Embodiment 1

[0064] Firstly, the garlic extract solution is carried out: 100 g of garlic is weighed, and the garlic is placed at a low temperature of 5° C. for 48 hours. Then measure 300ml of ethanol, weigh 0.5g of tea polyphenols, soak garlic, soak for 10 days at 10°C, then crush in a crusher, place in a centrifuge after crushing, and centrifuge at 10000r / min for 5 minutes. Get the supernatant to obtain 300ml of garlic extract. Dilute to 2000ml with distilled water.

[0065] Compounding of nutritional preservatives: Weigh 5g of urea, 5g of monoammonium phosphate, and 5g of potassium sulfate, place them in the above-mentioned preservative solution, weigh 2.5g of magnesium chloride, 2.5g of calcium chloride, 0.1g of copper sulfate, and 0.2g of zinc sulfate, Measure 0.01 g of indole acetic acid, 1.0 g of chitosan, and 0.01 g of nano-silicon dioxide, and add acetic acid to adjust the pH to 5.5 until they are completely dissolved. Form a complex fresh-keeping nutrient solution.

Abstract

The invention discloses a composite fresh-keeping nutritional agent for fruits and vegetables and a preparation method thereof. The fresh-keeping nutritional agent is prepared from garlic extract, mineral nutrient elements, an organic acid cell regulator and multifunctional sugar, wherein a method for preparing the garlic extract comprises the following steps: placing garlic at low temperature for preprocessing, then placing the garlic in a polar solution, and adding an antioxidant for soaking; executing crushing and pulping after soaking, and centrifugally separating supernatant to obtain the garlic extract. The fresh-keeping nutritional agent is used before picking of fruits and vegetables, integrates nutrition, freshness keeping and antisepsis, can effectively improve the taste quality of fruits and prolong the fresh-keeping period of fruits and vegetables.

Description

technical field [0001] The invention relates to a fruit and vegetable composite fresh-keeping nutrient and a preparation method thereof, belonging to the field of fruit and vegetable fresh-keeping. Background technique [0002] Fresh fruits and vegetables are rich in carbohydrates, proteins, vitamins, dietary fiber and other nutrients, and are an indispensable part of human nutrition. Especially with the improvement of living standards in our country, higher requirements are put forward for the quality of fruits and vegetables. [0003] After fresh fruits and vegetables are picked, under the influence of respiration and transpiration, the nutrients are gradually consumed and lost, and the appearance, taste and flavor become poor. , easy to breed bacteria and cause rot and deterioration. According to incomplete statistics, about 30% of fruits and vegetables per year rot and deteriorate during picking, transportation, storage and retailing, or lose product properties, result...
