FOODS AND BEVERAGES WITH INCREASED POLYUNSATURATED FATTY ACID CONTENT

摘要

A foodstuff or beverage such as bread or beer containing polyunsaturated fatty acid (PUFA) is produced using use for fermentation in the preparation thereof of a microbial cell such as Saccharomyces cerevisiae comprising at least two desaturases and having an increased in vivo desaturase efficiency in said cell, whereby said PUFA is produced in situ in said foodstuff or beverage by said metabolic activity of said microbial cell. The desaturases may be selected from delta-9 desaturase, delta-6 desaturase, delta-12 desaturase, delta-5 desaturase, omega-3 desaturase, delta-4 desaturase and delta-8- desaturase.
