Leguminosae-based instant prod. prepn. - by quickly cooking aq. flour suspension contg. alpha-amylase, starch degradation and drying

摘要

Quickly dissolved, i.e. instant, leguminosae-based powder prods. are prepd. (a) The dry legumes are first ground so finely that the exosperm also disintegrates and becomes inseparable from the fluor. (b) A suspension is then prepd. from this flour, added alpha-amylase and water. (c) The suspension is subjected to a continuous process, successively comprising : (i) intensive, short cooking; (ii) a reaction leading to at least partial degradation of starch in the cooked suspension by the alpha-amylase and (iii) drying. Short cooking retains natural flavours in prod., e.g. soups. The process is cheap, simple and obviates manual activity. Partial starch degradation eliminates bitter, raw taste.
