Re: Registration Statement on Form S-1

Gentlemen:

        You have requested my opinion as to the legality of the prior issuance of 1,677,596 shares and the issuance of 587,153 shares upon exercise of outstanding common stock purchase warrants by Pure Bioscience, (the “Corporation”) for a total of 2,264,749 shares of Common Stock (the “Shares”) being offered by the named selling securities holders pursuant to the Registration Statement on Form S-1 of the Corporation (the “Registration Statement”) to be filed on or about January 17, 2008.

        Pursuant to your request I have reviewed and examined:(1)The Articles of Incorporation of the Corporation, as amended (the “Articles”); (2) The Bylaws of the Corporation, as certified by the Secretary of the Corporation; (3) The minute book of the Corporation; (4) Certain resolutions of the Board of Directors of the Corporation; (5) The Registration Statement; (6) The General Corporation Law of the State of California; and (7) Such other matters as I have deemed relevant in order to form my opinion.

        Based upon the foregoing, I am of the opinion that the Shares, issued or if issued upon exercise of outstanding stock purchase warrants as described in the Registration Statement are or will have been duly authorized, legally issued, fully paid and non-assessable pursuant to the Articles and Bylaws of the Corporation and the General Corporation Law of the State of California.

        This opinion is furnished by me as counsel to the Corporation and is solely for your benefit and for reliance upon by the selling security holders and investors purchasing pursuant to the registration statement. Neither this opinion nor copies hereof may be relied upon by, delivered to, or quoted in whole or in part to any governmental agency or other person without our prior written consent.

        Not withstanding the above, I consent to the use of this opinion in the Registration Statement.

Very truly yours,

/s/ DENNIS BROVARONE
