Fresh keeping tablets for grapes

Abstract

The invention discloses fresh keeping tablets for grapes. The fresh keeping tablets are prepared from the following raw materials in percentage by weight: 60-70% of a fresh keeping agent, 2-4% of a Chinese herbal medicine antibacterial agent, 10-20% of a slow-release agent, and 1-2% of magnesium stearate, wherein the Chinese herbal medicine antibacterial agent is selected from but not limited to one or several kinds of celery seeds, dill seeds, alpine yarrow herb, hyssopus officinalis and camomile; the slow-release agent is selected from starch and / or microcrystalline cellulose; the fresh keeping tablets are prepared through the following steps: crushing the raw materials, screening the crushed materials, feeding the screened materials through calculation, mixing the fed materials, preparing wet granules, baking the wet granules, enabling the baked granules to be made into whole granules, totally mixing the whole granules, and tabletting the mixed granules, wherein the weight of each fresh keeping tablet is 0.7-0.8g. The fresh keeping tablets for the grapes provided by the embodiment of the invention have the advantages that in the storage and transportation process, the grapes stored with the fresh keeping tablets are high in fresh keeping degree, and the fresh keeping tablets take effect quickly, are convenient, simple and safe, and are free from any side effects. The grapes can maintain the original color and the original flavor for a long term.

Description

technical field [0001] The invention relates to a fresh-keeping agent, in particular to a novel grape fresh-keeping material capable of controlling the release of sulfur dioxide and having antibacterial and sterilizing effects, in particular to a grape fresh-keeping sheet. Background technique [0002] With the economic development of our country and the further opening of the fruit market, the market competition of grape products is becoming more and more fierce, and the demand and quality requirements of consumers for fresh grapes are also getting higher and higher. On the one hand, due to the strong seasonality of grape production, one of the most prominent factors affecting the contradiction between grape production and sales in the peak season of grape ripening is the processing and preservation technology of grapes. On the other hand, due to the relatively scattered areas of grape production, the rot loss rate of grapes reaches 20% to 30% during the annual transportati...

Problems solved by technology

However, the method adopted in the related art has the following problems: (1) because the combustion of sulfur is not easy to control, the concentration of sulfur dioxide gas produced is uneven, resulting in different degrees of freshness of the grapes, and even rottenness affects sales; (2) due to the use of The method of adding sulfur dioxide and other chemical mixtures can not effectively inhibit the pathogenic bacteria of the genus Botrytis, and there is a potential risk. Therefore, it is not conducive to the storage and transportation of grapes.
