    摘要: The aldehydes, N-hexanal, 3-(Z)-hexen-1-al and 2-(E)-hexen-1-al, and their corresponding alcohols are enzymatically produced in high yield from linoleic, linolenic acid or a natural precursor thereof such as hydrolyzed oil. The acid or natural precursor is mixed with soy flour containing lipoxygenase which converts the acid to 13-hydroperoxy-octadeca-9,11-dienoic acid or 13-hydroperoxy-octadeca-9,11,15-trienoic acid. Guava homogenate containing lyase is added to convert the 13-hydroperoxy-octadeca-9,11-dienoic acid into n-hexanal or the 13-hydroperoxy-octadeca-9,11,15-trienoic acid into 3-(Z)-hexen-1-al. The n-hexanal or 3-(Z)-hexen-1-al is recovered, or reduced with yeast to n-hexanol or 3-(Z)-hexen-1-ol, respectively. Alternatively, the 3-(Z)-hexen-1-al is isomerized to obtain 2-(E)-hexen-1-al which is recovered or reduced with yeast to 2-(E)-hexen-1-ol which is recovered. The yeast used for reducing and isomerizing is Saccharomyces cerevisiae. Steam distillation and/or extraction with an inert organic solvent is used in recovery of the aldehydes and alcohols.

    摘要: A process is disclosed for producing a heat-stable, yeast fermented malt reaction flavor concentrate which is of low volatility. The process involves preparing a malt flour such that it has sufficient fermentable sugars, fermenting the malt flour with yeast at a temperature of from about 10.degree. C. to about 60.degree. C. for a period of time from 1/2 to 6 hours and heating the fermented malt produced by the fermentation to inactive the yeast and develop flavors. The yeast fermented malt derived food flavorant may be incorporated into a foodstuff, preferably a ready-to-eat cereal or baked good at a level of from 0.3 to 5% by weight.
