Problems solved by technology

[0004] Preservatives are widely used in food production, but commonly used food preservatives are mainly chemically synthesized, which have a certain impact on human health
With the improvement of people's living standards, there is an increasing need for safer antistaling agents. Natural antistaling agents are new products that have been advocated and developed at home and abroad in recent years. However, natural antistaling agents are difficult to effectively maintain freshness and existing natural antistaling agents are difficult to effectively prolong storage. time

Embodiment 1

[0018] The yam is washed with clean water, and then the head and tail of the yam are removed. After air-drying, the epidermis is removed and cut into flaky yams with a thickness of about 1cm. The prepared yam is mixed with 0.05% γ-aminobutyric acid and calcium lactate 0.5%, 0.05% zinc acetate, 5% garlic extract, 12% loquat leaf extract, and pure water as the balance, soak in the preservative for 5 minutes. After soaking, let it air-dry naturally, put the processed fresh-cut yam into a fresh-keeping bag, tie the mouth, and store it in a cold storage at 4°C.

Embodiment 2

[0020] The yam is washed with clean water, and then the head and tail of the yam are removed. After air-drying, the epidermis is removed, and the yam is cut into flakes with a thickness of about 1cm. The prepared yam is mixed with 1% calcium lactate, 0.05% zinc acetate, 7% of the garlic extract, 15% of the loquat leaf extract, and pure water as the balance, soaked in preservative for 5 minutes. After soaking, let it air-dry naturally, put the processed fresh-cut yam into a fresh-keeping bag, tie the mouth, and store it in a cold storage at 4°C.

Abstract

The invention discloses a fresh-cut Chinese yam fresh keeping agent. The fresh keeping agent comprises 0-0.1% of gamma-aminobutyric acid, 0.5-2.5% of calcium lactate, 0.05-0.1% of zinc acetate, 5-10% of a garlic extract liquid, 10-20% of a loquat leaf extract liquid, and the balance of purified water. The fresh keeping agent overcomes the restriction problems of difficult effective freshness keeping and difficult effective preservation time prolongation of present natural fresh keeping agents, and can greatly prolong the preservation time of fresh-cut Chinese yam and greatly improve the preservation freshness of foods due to compounding of synthetic additives with low concentrations and pure natural additives.

Description

technical field [0001] The invention relates to the fresh-keeping and processing technology of agricultural products, in particular to a fresh-keeping agent for fresh-cut yams. Background technique [0002] Mechanical damage caused by cutting and other reasons during the processing of fresh-cut fruits and vegetables will cause tissue damage. The internal components of fruits and vegetables are prone to browning reaction when exposed to the air, thus changing the color. Furthermore, due to contact with the outside world, a large number of microorganisms will multiply, which will cause serious rot in fruits and vegetables. At present, the relevant fresh-cut fruits and vegetables sold on the market in my country are only processed through simple cleaning, and advanced processing techniques such as net treatment are not adopted. These will inevitably lead to many problems, such as: safety and health. The existence of many hidden dangers will directly lead to a decline in sale...
