Embodiment 1

[0030] A fresh-keeping method for Chinese toon sprouts based on ice-temperature storage of the present invention comprises the following steps: dissolving 0.9 g of betaine in 1000 mL of distilled water, and precooling at 2±0.5° C. for later use. The freshly picked Chinese toon shoots are transported to the cold storage in the shortest possible time, and the pre-cooled preservative solution is sprayed on the surface of the Chinese toon until a layer of mist-like water droplets are formed, and then dried naturally at 2±0.5°C and continue to pre-preserve. Cool to 24h. Then the toon shoots were bundled and put into LDPE fresh-keeping bags with a thickness of 0.05mm, each bag was filled with 800g, and then the mouth of the fresh-keeping bags was tied tightly, and then stored in a freezer at -0.5°C to 0°C.

Embodiment 2

[0032] A fresh-keeping method of Chinese toon sprouts based on ice-temperature storage of the present invention comprises the following steps: dissolving 1.3 g of betaine in 1000 mL of distilled water, and precooling at 2±0.5° C. for later use. The freshly picked Chinese toon shoots are transported to the cold storage in the shortest possible time, and the pre-cooled preservative solution is sprayed on the surface of the Chinese toon until a layer of mist-like water droplets are formed, and then dried naturally at 2±0.5°C and continue to pre-preserve. Cool to 24h. Then the toon shoots were bundled and put into LDPE fresh-keeping bags with a thickness of 0.03mm, each bag was filled with 1000g, and then the mouth of the fresh-keeping bags was tied tightly, and then stored in a freezer at -0.5°C to 0°C.

Embodiment 3

[0034]A fresh-keeping method of Chinese toon sprouts based on ice-temperature storage of the present invention comprises the following steps: dissolving 1.8 g of betaine in 1000 mL of distilled water, and precooling at 2±0.5° C. for later use. The freshly picked Chinese toon shoots are transported to the cold storage in the shortest possible time, and the pre-cooled preservative solution is sprayed on the surface of the Chinese toon until a layer of mist-like water droplets are formed, and then dried naturally at 2±0.5°C and continue to pre-preserve. Cool to 24h. Then the toon shoots were bundled and put into LDPE fresh-keeping bags with a thickness of 0.015mm, each bag was filled with 1200g, and then the mouth of the fresh-keeping bags was tied tightly, and then stored in a freezer at -0.5°C to 0°C.

Abstract

The invention relates to a fresh-keeping method of toona sinensis sprouts based on ice-temperature storage. The fresh-keeping method comprises the following steps of (1) collecting toona sinensis sprouts; (2) performing fresh keeping with a biological fresh-keeping agent and performing precooling; (3) performing spontaneous air-conditioning fresh-keeping packaging; (4) determining the temperature of ice temperature; and (5) performing ice-temperature preservation. According to the fresh-keeping method disclosed by the invention, internal nutrient components and external organoleptic quality of the toona sinensis sprouts are maintained to the great extent, and the breathe intensity and the lipid peroxidation degree of the toona sinensis sprouts are reduced. Besides, the activity of polyphenol oxidase PPO is restrained, the shelf life can be prolonged to about 40 days, and the purposes of storage and fresh keeping are achieved. The fresh-keeping technology is simple, convenient to operate, easy to implement, low in cost, environment-friendly, free from toxic effects on human bodies, and broad in market prospects.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping and storage of fruits and vegetables, and in particular relates to a fresh-keeping method for storing Chinese toon sprouts at ice temperature. Background technique [0002] Toon ( Toona Sinensis ) as a specialty resource in my country, not only has good color, aroma and taste, but also is rich in nutrition, ranking first among vegetables, and can secrete insect repellent substances during the growth process without spraying pesticides. It is a veritable green vegetable. Under the background that food safety and health issues have become the focus of attention at home and abroad, the advantages of Chinese toon, such as greenness, nutrition, and health care, can best meet the new trend of modern people's pursuit of healthy eating fashion. It is deeply loved by Chinese people and has a large international market. develop potential. However, the tender buds of Toona sinensis have strong season...
