Abstract

A process for removing alkaloid and peculiar smell caused by trimethylamine from konjak starch includes squeezing and digestion steps. Its advantages are simple process, low cost and no pollution. The resultant konjak starch can be used for food, adhesive, feed, etc.

Description

Technical field: [0001] The invention relates to the field of agricultural and sideline product processing, in particular to a method for eliminating alkaloids and peculiar smell in konjac flying powder. Background technique: [0002] Konjac (Amorphophallus konjac) is a perennial herb of Araceae (Araceae) genus Amorphophallus blume, also known as konjac. It is mainly distributed in the mountainous areas of southwest my country. The bulbs are rich in konjac glucomannan, starch, protein, minerals and alkaloids. It has been used for nearly two thousand years. It has been recorded in the Song Dynasty "Kaiyuan Materia Medica" that "Konjac root It is effective to spread carbuncle and swollen poison.” From this, it can be seen that the main application of konjac in ancient my country was in food and in combination with medicine. The development of konjac planting and deep processing is of great significance to poverty alleviation, environmental protection, and accelerating the deve...
