Abstract

The invention provides a preparation method for a kumquat fresh-keeping solution. A main flow of the method comprises the following steps of: hydrolyzing fresh high-quality fish scales to obtain a collagen solution; adding nano titanium dioxide into the collagen solution; agitating sufficiently and uniformly to obtain a compound fresh-keeping solution. after kumquats are soaking into the compound fresh-keeping solution for several minutes and then taken out, one layer of a fresh-keeping film is formed on the surface and the formed fresh-keeping film is easy to wash; the fresh-keeping film is harmless to the human body after being ingested by a human body; ingested micro-molecular collagens are beneficial to the human body. The compound fresh-keeping solution provided by the invention is environment-friendly and safe, the preparation method is simple and feasible, and the fresh-keeping effect is good.

Description

technical field [0001] The invention relates to fruit fresh-keeping technology, in particular to a preparation method of kumquat fresh-keeping liquid. Background technique [0002] Fruits and vegetables are usually listed in a fresh form, rich in nutrition and suitable in taste, and are indispensable foods in people's lives. Fresh fruits and vegetables are harvested and consumed by humans. Due to their own respiration and pathogenic organisms, a large number of fruits and vegetables are rotted and lost every year. [0003] Kumquat, belonging to Rutaceae and Kumquat genus, is native to China and has a cultivation history of more than 1,700 years so far, with an annual output value of more than 100 million yuan. The fruit is oval, golden yellow, shiny, juicy and delicious, and can be eaten with the skin on. Kumquat is not only beautiful, but its fruit is rich in vitamin C, kumquat glycosides and other ingredients, which can prevent colds, lower blood lipids, and have a certa...
