Problems solved by technology

At present, most of the anti-mildew preservatives used on garlic sprouts are general-purpose anti-mold and fresh-keeping agents for fruits and vegetables, which are not highly targeted, and most of them are low-toxic chemical preservatives. The dosage and limit are not standard, and there are food safety hazards. Biological preservatives with advantages such as safety appear on the market, but due to high cost and unsatisfactory fresh-keeping application effect, their promotion and use are limited

Embodiment 1

[0013] Embodiment 1: proportioning (percentage by weight): chitosan 5%, ethylparaben 0.05%, propylparaben 0.05%, natamycin 0.005%, tekedo 0.05%, all the other are water ( solvent).

[0014] How to use: Mix the above ingredients evenly, soak the sprouts with this solution, put them in the warehouse in time, and pre-cool them to 0-3°C. After the sprouts are slightly dry, put them into polyvinyl chloride silicon window fresh-keeping bags for garlic sprouts. Store at -0.8℃~-0.3℃.

[0015] The application effect of the special high-efficiency anti-mold antistaling agent prepared by the embodiment 1 of the present invention is as follows:

[0016] Experimental material: Shandong Anqiu garlic sprouts, harvested in time in the middle and late May

[0017] Storage temperature: -0.8℃~-0.3℃

[0018] PVC silicon window bag packing: 20kg / bag

[0019] Treated with the special antistaling agent of the present invention (CL), treated with common garlic sprouts antistaling agent (the activ...

Embodiment 2

[0026] Embodiment 2: Proportioning (percentage by weight): 3% chitosan, 0.1% propylparaben, 0.01% natamycin, 0.08% Tecdo, and the rest are water (solvent).

[0027] Using method is the same as embodiment 1.

Embodiment 3

[0028] Embodiment 3: Proportioning (percentage by weight): 4% chitosan, 0.08% ethylparaben, 0.008% natamycin, 0.07% tekedo, and the rest is water (solvent).

[0029] Using method is the same as embodiment 1.

Abstract

The invention discloses a high-efficiency mould-proof preservative special for preserving garlic stems, which consists of the following components in percentage by weight: 1 to 5 percent of chitosan, 0.05 to 0.1 percent of nipagin ester, 0.001 to 0.01 percent of natamycin, 0.05 to 0.1 percent of thiabendazole and the balance of water. The garlic stem preservative has low cost and is convenient toapply and high-efficiency and safe; by combining measures and technology such as low temperature, spontaneous modified atmosphere packaging and the like, the garlic stems treated by the preservative are bright green, have tender tissues and are still fresh after being stored for 6 to 8 months, and mould does not grow in garlic involucre and strips; the commodity rate reaches 95 percent; and the preservation effect is good.

Description

technical field [0001] The invention relates to a fresh-keeping agent for fruit and vegetable storage, in particular to a high-efficiency mold-proof and fresh-keeping agent for garlic sprouts. technical background [0002] Garlic sprouts are the flower stems of bolting garlic, also known as garlic seedlings and garlic cloves. They are rich in protein, carbohydrates, calcium, phosphorus, iron and other elements, and also contain allicin, which is a physiologically active component. It is a unique vegetable in my country. One of the vegetable varieties with larger storage capacity after harvest. In my country, the annual storage capacity of garlic sprouts is relatively large, about 1 billion catties in general years, and 2 billion catties in more years. [0003] The respiration type of garlic sprouts after harvest is climacteric, with strong physiological metabolism, enhanced transpiration, and easy to lose water, wilt, and deteriorate due to aging. Because the harvesting pe...
