Embodiment 1

[0053] Pack into the polyethylene film bag that has added 8g / kg antistaling agent through the precooling, selection of 2.0kg of the shallot, and store in the cold storage at 0°C. The antistaling agent includes 8% potassium permanganate, potassium permanganate, 8% Tartaric Acid, 15% Grapefruit Extract and 69% Diatomaceous Earth.

Embodiment 2

[0055] Pack into the polyethylene film bag that has added 10g / kg antistaling agent through the precooling, selected 2.0kg of the shallots onions, and store in a cold storage at 3°C. The antistaling agent includes 10% potassium permanganate, potassium permanganate, 5% Tartaric Acid, 20% Grapefruit Extract and 65% Bentonite Clay.

Embodiment 3

[0057] Pack into the polypropylene film bag that has added 16g / kg antistaling agent through the precooling, selected 2.0kg of the shallots onion, and store in a cold storage at 9°C. The antistaling agent includes 5% potassium permanganate, potassium permanganate, 10% Tartaric Acid, 10% Grapefruit Extract and 75% Vermiculite.

Abstract

The invention provides a preservative and its preparation method and application. The preservative is mainly prepared from the following raw materials: potassium permanganate, tartaric acid, grapefruit extract and porous media. Potassium permanganate, tartaric acid, grapefruit extract and porous medium in the antistaling agent of the present invention cooperate with each other, not only effectively absorb the ethylene produced by the shallots, but also significantly inhibit the activity of bacteria and fungi during storage, effectively delaying the preservation of shrimp. The metamorphism of shallots has a remarkable effect on freshness preservation.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping and storage, and relates to a fresh-keeping agent and its preparation method and application. Background technique [0002] Allium schoenoprasum L., also known as catkins, shallots or chives, is native to Europe and belongs to the Allium genus. It has a strong aroma and a soft taste. It is a commonly used spice in Western or Japanese cuisine. Ezo scallion is clustered, the plant is erect, the plant height is about 45-50cm, the diameter of the tubular leaf is about 3-5cm, the leaves are slender and dark green, the plant is more heat-resistant but not cold-resistant, and the suitable growth temperature is 22-24℃, which is good for soil Strong adaptability, likes humidity and is not drought-tolerant. [0003] In recent years, Chongming District of Shanghai has introduced all-green onions from Europe, processed them with vacuum freeze-drying technology, and exported them to Japan, Europe and th...
