CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements in this prospectus and in any prospectus supplement we may file constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.  These statements relate to future events concerning our business and to our future revenues, operating results and financial condition.  In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “forecast,” “predict,” “propose,” “potential” or “continue,” or the negative of those terms or other comparable terminology.

Any forward looking statements contained in this prospectus or any prospectus supplement are only estimates or predictions of future events based on information currently available to our management and management’s current beliefs about the potential outcome of future events.  Whether these future events will occur as management anticipates, whether we will achieve our business objectives, and whether our revenues, operating results or financial condition will improve in future periods are subject to numerous risks.  There are a number of important factors that could cause actual results to differ materially from the results anticipated by these forward-looking statements.  These important factors include those that we discuss under the heading “Risk Factors” and in other sections of our Annual Report on Form 10-K for the year ended December 31, 2013 and our Form 10-Q for the quarterly period ended March 31, 2014, all filed with the Securities and Exchange Commission (SEC), as well as in our other reports filed from time to time with the SEC that are incorporated by reference into this prospectus.  You should read these factors and the other cautionary statements made in this prospectus and in the documents we incorporate by reference into this prospectus as being applicable to all related forward-looking statements wherever they appear in this prospectus or the documents we incorporate by reference into this prospectus.  If one or more of these factors materialize, or if any underlying assumptions prove incorrect, our actual results, performance or achievements may vary materially from any future results, performance or achievements expressed or implied by these forward-looking statements.  We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

We were founded in 1998, and our principal executive offices are located at 6720 N. Scottsdale Road, Suite 390, Scottsdale, AZ 85253.  Our telephone number is (602) 522-3000.  Our website is located at www.ricebrantech.com.  Information contained on, or that can be accessed through, our website is not part of this prospectus.

PRIVATE PLACEMENT

On March 20, 2014, we entered into a Note and Warrant Purchase Agreement (Purchase Agreement) and a Registration Rights Agreement (Registration Rights Agreement) in connection with a private placement of its securities to certain accredited investors for aggregate gross proceeds of approximately $4,898,649 (approximately $4.3 million after estimated offering expenses).  Pursuant to the Purchase Agreement, the investors purchased (i) an aggregate of $4,898,649 in convertible notes which are convertible into shares of common stock of the Company at a price of $5.25 per share, and (ii) five-year warrants to purchase an aggregate of 1,399,614 shares of common stock at an exercise price of $5.25 per share. On March 20, 2014, our common stock’s closing price was $5.09 per share.

Under the terms of the Purchase Agreement, we could sell additional securities at one or more subsequent closings within sixty days of the initial closing.  On May 19, 2014, the Company sold additional securities under the Purchase Agreement consisting of (i) an aggregate of $1,249,762.50 in convertible notes which are convertible into shares of common stock of the Company at a price of $5.25 per share, and (ii) five-year warrants to purchase an aggregate of 357,075 shares of common stock at an exercise price of $5.25 per share.

The convertible notes had an annual interest rate equal to 5% and automatically converted into shares of our common stock once we obtained shareholder approval to increase the number of authorized shares of common stock to enable the issuance of the shares underlying the convertible notes and the warrants.  On May 30, 2014, all of the convertible notes converted into 1,180,567 shares of common stock of Company.

Pursuant to the Registration Rights Agreement, we are obligated to file a registration statement with the Securities and Exchange Commission within 30 calendar days the date we obtained shareholder approval to increase its authorized shares of common stock, which occurred May 30, 2014, covering the possible resale from time to time in the future of the shares of common stock underlying the convertible notes and the warrants.

DESCRIPTION OF OUR COMMON STOCK

The selling stockholders may, from time to time, sell, transfer, or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market, or trading facility on which the shares are traded or in private transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.  This prospectus provides you with a general description of the common stock the selling shareholders may offer.

The description below of our capital stock and provisions of our articles of incorporation and bylaws are summaries and are qualified by reference to the articles of incorporation and the bylaws.  These documents are filed as exhibits to the registration statement of which this prospectus is a part.

Our authorized capital stock consists of 25,000,000 shares of common stock, no par value, and 20,000,000 shares of Preferred Stock, no par value, of which 3,000,000 shares are designated Series A Preferred Stock, 25,000 shares are designated Series B preferred Stock, 25,000 shares are designated Series C Preferred Stock, 10,000 shares are designated Series D Preferred Stock and 2,743 shares are designated Series E Preferred Stock. As of June 20, 2014, there were 6,445,306 shares of common stock outstanding and no shares of preferred stock outstanding.

Common Stock

Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock are entitled to receive ratably dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for that purpose. In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are fully paid and nonassessable, and the shares of common stock to be issued upon the closing of this offering will be fully paid and nonassessable.

The holders of common stock are entitled to one vote per share on all matters to be voted upon by the shareholders.  Under certain circumstances, California law permits the holders of our common stock to cumulate their votes for the election of directors, in which case holders of less than a majority of the outstanding shares of our common stock could elect one or more of our directors. Holders of our common stock have no preemptive, subscription, or redemption rights. The outstanding shares of common stock are fully paid and nonassessable. The rights and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of holders of shares of preferred stock that we may designate and issue in the future.

Effect of Certain Provisions of our Articles of Incorporation and Bylaws

Our articles of incorporation and bylaws contain certain provisions that could make the following transactions more difficult:

·

acquisition of us by means of a tender offer;

·

acquisition of us by means of a proxy contest or otherwise; or

·

removal of our incumbent officers and directors.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids and to promote stability in our management.  These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

·

Undesignated Preferred Stock.  The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us.  These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company.

---

·

Shareholder Meetings.  Our bylaws provide that a special meeting of shareholders may be called only by the President or by the board of directors or the Chairman of the Board or by one or more shareholders holding shares in the aggregate entitled to cast not less than 10% of the votes at that meeting.

·

Requirements for Advance Notification of Shareholder Nominations and Proposals.  Our bylaws establish advance notice procedures with respect to shareholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee of the board of directors.

·

Board of Directors Vacancies.  Under our bylaws, any vacancy on the board of directors, including a vacancy resulting from an enlargement of the board of directors, may only be filled by vote of a majority of the remaining directors.  The classification of the board of directors and the limitations on the removal of directors and filling of vacancies would have the effect of making it more difficult for a third party to acquire control of us, or of discouraging a third party from acquiring control of us.

·

Board of Directors Size.  Within the range specified by our bylaws, our board of directors determines the size of our board and may create new directorships and elect new directors, which may enable an incumbent board to maintain control by adding directors.

·

Indemnification. Our articles of incorporation and our bylaws, as amended, provide that we will indemnify officers and directors against losses as they incur in investigations and legal proceedings resulting from their services to us, which may include service in connection with takeover defense measures.

Listing

Our common stock is listed on the NASDAQ Capital Market under the symbol “RIBT”.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

USE OF PROCEEDS

We will not receive any of the proceeds from any sale or other disposition of the common stock covered by this prospectus. We will receive proceeds upon the cash exercise of the warrant for which underlying shares of common stock are being registered hereunder. Assuming full cash exercise of the warrants at the exercise price of $5.25 per underlying share of common stock, we will receive proceeds of approximately $9.2 million. We currently intend to use the cash proceeds from any warrant exercise for working capital and general corporate purposes. We may also use a portion of the cash proceeds to acquire or invest in complementary businesses, technologies, product candidates, or other intellectual property, although we have no present commitments or agreements to do so. The amount and timing of our actual use of proceeds may vary significantly depending upon numerous factors, including the actual amount of proceeds we receive and the timing of when we receive such proceeds. In addition, the terms of the warrant provide that it may be exercised on a cashless basis if at the time of exercise, the shares of common stock underlying the warrant are not subject to a registration statement or there has been a failure to maintain the effective registration of such shares. We will not receive any cash proceeds as a result of warrant that are exercised on a cashless basis pursuant to such terms of the warrant.

PLAN OF DISTRIBUTION

A selling stockholder of the securities offered by this prospectus and any of its pledgees, assignees and successors-in-interest may, from time to time, sell any or all of the securities covered hereby on the NASDAQ Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions.  These sales may be at fixed or negotiated prices.  A selling stockholder may use any one or more of the following methods when selling securities:

·

ordinary brokerage transactions and transactions in which the broker‑dealer solicits purchasers;

·

block trades in which the broker‑dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·

purchases by a broker‑dealer as principal and resale by the broker‑dealer for its account;

·

an exchange distribution in accordance with the rules of the applicable exchange;

·

privately negotiated transactions;

·

settlement of short sales;

---

·

in transactions through broker‑dealers that agree with the selling stockholder to sell a specified number of such securities at a stipulated price per security;

·

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·

a combination of any such methods of sale; or

·

any other method permitted pursuant to applicable law.

The selling stockholder may also sell securities under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholder may arrange for other brokers-dealers to participate in sales.  Broker-dealers may receive commissions or discounts from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440, and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

In connection with the sale of the securities or interests therein, the selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume.  The selling stockholder may also sell securities short and deliver these securities to close out its short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities.  The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales.  In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.  The selling stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities.  The Company has agreed to indemnify the selling stockholder against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because the selling stockholder may be deemed to be an “underwriter” within the meaning of the Securities Act, it will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder.  In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. The selling stockholder has advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale securities by the selling stockholder.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the selling stockholder without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect, or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect.  The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution.  In addition, the selling stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholder or any other person.  We will make copies of this prospectus available to the selling stockholder and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The estimated expenses payable by the registrant in connection with the issuance and distribution of the securities being registered are as follows:

*	Estimated solely for the purposes of this Item.  Actual expenses may vary.

Item 15. Indemnification of Directors and Officers

The California General Corporation Law and our Articles of Incorporation and Bylaws provide that we may indemnify our officers, directors, employees or agents or former officers, directors, employees or agents, against expenses actually and necessarily incurred by them, in connection with the defense of any legal proceeding or threatened legal proceeding, except as to matters in which such persons shall be determined to not have acted in good faith and in our best interest.  This means that if indemnity is determined by the Board of Directors to be appropriate in any case we and not the individual might bear the cost of any suit that is filed by a shareholder against the individual officer, director or employee unless the court determines that the individual acted in bad faith. These provisions are sufficiently broad to permit the indemnification of such persons in certain circumstances against liabilities arising under the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors and officers, and to persons controlling our company pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 16. Exhibits

---

Item 17. Undertakings

(a)

The undersigned registrant hereby undertakes:

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

---

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

---

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 15 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
