Problems solved by technology

[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

Embodiment 1

[0019] Example 1: Select 1.0 g of thorny old shoots with the same size, no mechanical damage, and no pests and diseases. After cleaning, place it at 85 ° C to make 0.10% vitamin C, 0.05% cysteine, 0.02% sodium sulfite, and 0.30% lemon acid, 0.30% calcium chloride (w / v) in an aqueous solution of the green protection compound, blanching for 3 minutes, and then rapidly cooled and vacuum-packed. Its chlorophyll a content was determined to be 0.0836 mg / L, and the chlorophyll b content was 0.0260 mg / L.

Embodiment 2

[0020] Embodiment 2: Select 1.0 g of thorny old shoots with the same size, no mechanical damage, and no pests and diseases. After cleaning, place it at 85 ° C to make 0.20% vitamin C, 0.10% cysteine, 0.03% sodium sulfite, and 0.30% lemon acid, 0.20% calcium chloride (w / v) in an aqueous solution of the green protection compound agent, blanching for 3 minutes, and then rapidly cooled and vacuum-packed. Its chlorophyll a content was determined to be 0.1050 mg / L, and the chlorophyll b content was 0.0291 mg / L.

Embodiment 3

[0021] Embodiment 3: select 1.0g of thorny old shoots with the same size, no mechanical damage, no damage by diseases and insect pests, place it at 85°C after cleaning, and make 0.20% vitamin C, 0.15% cysteine, 0.05% sodium sulfite, 0.40% lemon acid, 0.10% calcium chloride (w / v) in an aqueous solution of the green protection compound agent, blanching for 3 minutes, and then rapidly cooled and vacuum-packed. Its chlorophyll a content was determined to be 0.1226 mg / L, and the chlorophyll b content was 0.0361 mg / L.

Abstract

The invention relates to an aralia mandshurica green-protecting compounded agent and belongs to the field of agricultural product processing. The invention develops a food-grade compounded green-protecting agent specially used for aralia mandshurica and aims at solving the problem that the aralia mandshurica can get yellow easily and is not applicable to long-term storage and the current situation that a green-protecting agent containing heavy metal ions is mainly adopted for green protecting in the fruit and vegetable fresh-keeping industry. The aralia mandshurica blanched by virtue of the aralia mandshurica green-protecting compounded agent is emerald green in overall, full in appearance and long in preservation time. The green-protecting compounded agent provided by the invention has the advantages that on the basis that three green-protecting agents, namely vitamin C, cysteine and sodium sulfite, respectively fully play roles, citric acid and calcium chloride are added to enhance the synergistic green-protecting effect, so that chlorophyll of the aralia mandshurica is effectively protected, and the chlorophyll loss ratio is reduced; and no heavy metal ion is added, so that the green-protecting compounded agent serves as a green, safe and efficient green-protecting method, and a basis can be provided for development of the industries such as aralia mandshurica green-protecting and fresh-keeping, green processing of aralia mandshurica and development of related green foods.

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, ni...
