Abstract

The invention discloses a tomato coating compound preservative. The compound preservative is composed of the following components in mass percentage: 0.5-1% of lecithin, 0.05-0.1% of phytic acid, 1-2% of polyoxyethylene sorbitan oleate, 0.05-0.1% of konjac flour, 0.1-0.3% of xanthan gum, 0.2-0.4% of sodium chloride, 0.3-0.5% of nano silica, 0.5-1% of glycerine, 0.3-0.5% of sodium hexametaphosphate and the balance of gardenia extract. According to the invention, the various components of the tomato coating compound preservative cooperate with each other, so that the compound preservative has the functions of anti-bacteria, water retention, color protection and the like, is safe and efficient, low in cost, good in film formation performance, can improve the tomato appearance and prolong freshness time of tomatoes and has quite high commercial value. The invention also discloses a preparation method for the tomato coating compound preservative. The preparation method is simple in technological procedure, strong in operability and suitable for large-scale industrial production and application.

Description

technical field [0001] The invention relates to the technical field of food fresh-keeping, in particular to a tomato-coated composite fresh-keeping agent and a preparation method thereof. Background technique [0002] Tomatoes, commonly known as tomatoes, are rich in vitamins and other nutrients and have a good taste. They can be eaten raw as fruits, cooked vegetables or cooking accessories, and are very popular among the masses. Now, although the transportation is convenient, and there is the advance and delay function of the greenhouse, the tomato skin is thin and soft, fresh and perishable, and easy to damage, which brings a lot of inconvenience to both storage and transportation. In the northern market, there are still obvious differences between off-season and peak season. The commonly used tomato fresh-keeping technologies in China mainly include cold storage, controlled atmosphere fresh-keeping, drying and fresh-keeping, etc., but the above-mentioned technologies all...
