    摘要: Highly resistant granular starches may be produced which have unique and useful properties, including high enzyme resistance, dietary fiber, a unique molecular weight distribution, a high melting temperature and a high heat of gelatinization (Delta H) indicative of excellent processing tolerance. These starches may be prepared for example by heating a high amylose starch having at least 40% by weight amylose content and at a percent moisture and temperature insufficient to destroy the granular nature of the starch, and digesting the amorphous regions using alpha-amylase or a chemical reagent.

    摘要: The invention provides a process for preparing medium chain dicarboxylic acids by biochemical oxidation so that in particular C.sub.8 and C.sub.10 dicarboxylic acids are prepared from nontoxic levels of C.sub.8 -C.sub.14 fatty acids using a nitrogen-restricted yeast propagated in a carbon substrate containing growth medium. Preferably the fatty material is supplied to the yeast in the form of a glyceride. Also it is preferred that the amount of nitrogen in the biomass is between 4 and 9%, in particular between 5.5 and 7% (w/w).
