A kind of thorn old bud green protection compound agent

Abstract

The invention discloses a compound agent for protecting the greenness of thorn old buds, which belongs to the field of agricultural product processing. Aiming at the problem that the old thorn buds are easy to yellow and difficult to be stored for a long time and the current situation that the fruit and vegetable preservation industry mostly uses green protection agents containing heavy metal ions, a food-grade compound green protection agent specially used for the green protection of the old thorn buds is developed. agent. The old spiny shoots blanched by the green protecting agent of the present invention have emerald green vegetable body, plump appearance and long fresh-keeping time. The invention provides a green protection compound agent, under the premise that the three green protection agents of vitamin C, cysteine ​​and sodium sulfite play their roles respectively, the compound agent enhances the synergistic green protection effect by adding citric acid and calcium chloride , so as to effectively protect the chlorophyll of old thorn buds, reduce the loss rate of chlorophyll and add no heavy metal ions. It is a green, safe and efficient green protection method, which can be used for green protection and freshness of thorn old shoots, green processing and research and development of related green foods Provide a basis for the development of other industries.

Description

technical field [0001] A green-protecting compound agent for thorn old shoots belongs to the field of agricultural product processing technology, and specifically relates to a compound technology of a food-grade green-protecting agent without heavy metal ions, which is safe, green, and efficient, and finally obtains vegetables without yellowing and high chlorophyll content. The old thorn bud products with higher nutrient content and less loss of nutrients provide a basis for the development of industries such as green protection and freshness of the old thorn buds, green processing and research and development of related green foods. Background technique [0002] The old shoots of thorns have extremely high nutritional value, and its nutritional components include protein, fat, carbohydrates, dietary fiber, vitamin B 2 , Vitamin B 1 , niacin, vitamin C, 16 kinds of amino acids and 22 kinds of trace elements, among which the content of calcium, manganese, iron, titanium, nic...

[0005] The patent "Preparation Method and Product of Puffed Wild Vegetable Chips" (publication number: CN103461892A, publication date: December 25, 2013) discloses "put the blanched wild vegetables at 100°C and contain 1% by mass Salt, 0.1% ascorbic acid and 2% citric acid in a mixed aqueous solution, blanched for 1 min, and then rinsed with running water." However, it is mainly for the production of puffed products, and green protection is not the main indicator. There is no in-depth discussion, and the green protection agent Large doses, especially large doses of citric acid, can easily affect the flavor of the product

[0006] The green protection agent involved in the present invention is composed of vitamin C, cysteine, sodium sulfite, citric acid, and calcium chloride. There is no report on the research on the greening effect of thorny old shoots after compounding the greening agent as an organic whole
