[0001] Preparation of low DE value maltodextrin by jet liquefaction enzyme method, the invention relates to an enzyme engineering preparation method and product application of low DE value maltodextrin. Background technique
[0002] When starch is treated with heat, acid or specific enzymes, it can produce a kind of degradation products mainly composed of a series of oligosaccharides and polysaccharides such as D-glucose, maltose, maltobiose and maltotriose. Due to the increase of reducing end groups during the degradation process, the degree of degradation can be expressed by DE (Dextrose Equivalent, glucose equivalent) value. Theoretically speaking, the DE value of pure starch is close to 0, while the DE value of glucose is 100. Therefore, as the DE value increases, its hydrolysis degree also increases gradually.
[0003] Maltodextrin is a starch hydrolysis product with a DE value of less than 20. It is between starch and starch sugar, and it is a nutriti...
