The invention discloses a making method of preserved black
jerusalem artichoke, and belongs to the technical field of
food processing. The problems that in the existing preserved
jerusalem artichoke production technology, preserved
jerusalem artichoke is not suitable for
glycosuria patients due to the fact that saccharose is exogenously added, and
food safety is potentially affected due to the fact that
sodium hydrogen sulfite and other food additives are added are solved. The
processing technological process comprises the following steps of
raw material freezing, sorting and cleaning,
processing through
zymogen, sealing,
fermentation,
drying, packaging, finished product forming and
cold storage. Compared with raw jerusalem artichoke, in the preserved black jerusalem artichoke, the certain synanthrin content is reserved, the content of
reducing sugar and polyphenols is obviously increased, a large number of melanoidins are produced, the product reserves the functions of regulating
blood sugar in two ways, lowering blood fat, proliferating bifidobacteria, promoting mineral substance absorption, preventing and treating
constipation, improving intestinal tract microenvironment, enhancing
immunity, resisting
cancer and preventing
obesity of the synanthrin in the raw jerusalem artichoke to the certain degree, and the preserved black jerusalem artichoke has the stronger
antioxidant function due to the fact that the content of the polyphenols and melanoidins is obviously increased.
