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.

Described is a process for the preparation of compositions of matter containing octalactones defined according to the structure: ##STR1## which includes the stereoisomers having the structures: ##STR2## by means of the sequential steps of (i) fermentation of caprylic acid or the ethyl ester of caprylic acid defined according to the generic structure: ##STR3## wherein R is hydrogen or ethyl using a microorganism selected from the group consisting of:Mortierella ramanniana var. ramanniana--CBS 112.08Mortierella ramanniana var. ramanniana--CBS 478.63Choanephora cucurbitarum--NRRL 2744Mortierella isabellina--IFO 8183Mortierella isabellina--IFO 8309Mortierella nana--IFO 8794Mortierella isabellina--IFO 7824Mortierella vinacea--IFO 6738whereby a gamma hydroxy octanoic acid defined according to the structure: ##STR4## is formed; and (ii) lactonization of the resulting gamma hydroxy octanoic acid by means of simultaneous acidification and heating according to the reaction sequence: ##STR5##
摘要:
A process for the production of a flavoring agent, in which an aqueous suspension of a protein-rich material is prepared, the proteins are solubilized by hydrolysis with a neutral or alkaline protease, the suspension is heat-treated at a mildly acidic pH value and is then ripened with koji enzymes.
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.
摘要:
A novel hydroxy-cinnamic acid ester hydrolase can be obtained by cultivating, in a medium, a mold strain belonging to Genus Aspergillus or Genus Botrytis and having an ability to produce a hydroxy-cinnamic acid ester hydrolase specifically hydrolyzing the ester linkage of hydroxy-cinnamic acid ester substances represented by the following general formula: ##STR1## wherein R is hydrogen atom, hydroxyl group or methoxyl group and X is tartaric acid residue or quinic acid residue, followed by collecting the hydroxy-cinnamic acid ester hydrolase from the cultivated product.
