Problems solved by technology

[0003] However, most coating preservatives also have many problems. One is that they contain chemical components that are harmful to the human body, which do not meet the requirements of green safety; Condensed water appears, the coating agent is easily soluble in water and loses its protective effect
[0004] The emergence of pullulan (Pullulan, also known as pullulan, pullulan, pullulan, pullulan or pullulan) as the main component of coating preservatives has partially solved the above problems, but There is also the problem that the amount of pullulan sugar is large, the cost is high, and the water resistance of the formed film is poor; the application of the two-component fruit and vegetable coating film preservative also has the problems of complicated processing technology and poor operability

Abstract

The invention relates to the technical field of refreshing, in particular to a fruit and vegetable coating antistaling agent, aiming at providing the fruit and vegetable coating antistaling agent which has low cost, green initiative and convenient application. The invention has the following technical scheme in particular: each liter of the fruit and vegetable coating antistaling agent contains 5-50g of pullulan sugar, 0.2-2g of preservatives, 1-20g of sorbitol, 5-50g of hydrophobizing agent, 1-30g of surfactant and the balance of solvent. The invention has the following advantages: the film-forming agent used in the invention contains less usage of the pullulan sugar, thus the cost is lowered; the hydrophobizing agent is added without the influence of condensed water. The preparation of the coating agent and the operation of the coating have simple steps and strong operability.

Description

Technical field [0001] The invention involves the field of fresh -keeping technology, which is specifically a fruit and vegetable coating film preservation agent. Background technique [0002] Fresh fruits and vegetables are rotten after the harvesting of fresh fruits and vegetables. According to statistics, about 10-20 % of fresh fruits and vegetables in developed countries are rotten due to postponed diseases, and developing countries have reached 40-50 %.Due to the backwardness of fresh -keeping technology, the direct waste and loss rate of fruits produced in China each year is as high as 38 %.In order to solve the problem of rotting after the pumping and vegetables, the shelf period is extended. At present, the hotspots of domestic and foreign research are concentrated in the edible coating film preservation method.Edible coating film is a thin film with a porous network structure formed by the interaction between different molecules between different molecules, and covers th...
