Problems solved by technology

[0005] In order to increase the health-care efficacy of vinegar, relevant researchers have developed health-care vinegar, for example: Chinese Patent Application No. CN201010187965.8 "Production Process of Papaya Vinegar", Chinese Patent Application No. CN201210162462.4 "A Tea Vinegar Beverage and Its Preparation Method", etc. These patents all use traditional methods to prepare health-care vinegar with a certain effect. The ingredients are relatively single and the taste is average.
[0006] At present, there is no patent report containing chitosan oligosaccharide vinegar. It is necessary to develop fruit vinegar products rich in chitosan oligosaccharides and having good taste and nutritional and health effects.

Abstract

The invention discloses a fermentation preparation method of chitooligosaccharide-rich papaya fruit vinegar, belonging to the field of food processing. The papain-rich papayas and chitosan-rich shrimp-shells are subjected to mixed fermentation, and the papain is utilized to degrade the chitosan, so that the fermented vinegar contains rich chitooligosaccharides. By comprehensively utilizing the shrimp processing waste shrimp shells and rich papain, the shrimp shell-papaya fruit vinegar lowers the cost, contains the nutritive value of papayas, and thus, has favorable health-care function.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a fermentation preparation method of papaya fruit vinegar rich in chitosan. Background technique [0002] Vinegar is a traditional condiment in major Chinese cuisines. The vinegar is brewed from grain, sugar, and ethanol through microbial fermentation; synthetic vinegar is made by adding water, sour agents, and seasonings to edible acetic acid. Blended with spices and food coloring. Vinegar has the effects of reducing swelling, detoxification, digestion, and dispersing silt. Drinking an appropriate amount of vinegar is of great help to your health. [0003] Papaya, Rosaceae Papaya genus, shrub or small tree, up to 5-10 meters, leaves oval-ovate or oval-oblong, rare obovate, papaya is delicious and has therapeutic effects. The proteolytic enzymes contained in papaya can compensate for the secretion of pancreas and intestines, supplement the insufficiency of gastric juice, help dec...
