Method for preparing actinidia chinensis preservative film master batch containing rare-earth complex

Abstract

The invention relates to a method for preparing an actinidia chinensis preservative film containing a rare-earth complex. The technical scheme is as follows: the method comprises the steps: weighing acrylamide and purple soil powder, of which the grain size is 125 microns to 150 microns, putting the acrylamide and the purple soil powder into a reactor, adding distilled water into the reactor, heating the reactor to the temperature of 75 DEG C to 90 DEG C, adding potassium persulfate into the reactor with stirring, carrying out a stirring reaction for 1.5 to 2.5 hours at the temperature of 75 DEG C to 90 DEG C, adding an oil tea fruit peel extract into the reactor, and carrying out a stirring reaction for 1 to 3 hours at the temperature of 75 DEG C to 90 DEG C; adding a 10% (mass concentration) sodium hydroxide solution into the reactor, carrying out a stirring reaction for 1 to 3 hours at the temperature of 75 DEG C to 90 DEG C, adding acid to adjust the pH value to 7, and carrying out drying and crushing, thereby obtaining an oil tea fruit peel extract flocculant. According to the method, the oil tea fruit peel extract is used as a preparing raw material, the source is wide, and the cost is low; the comprehensive utilization of the oil tea fruit peel extract is facilitated, and the emission of wastes is reduced. The method has the advantages that the preparation process is simple, the conditions are mild, the cost is relatively low, the degradation is easy, the use is safe, and the like.

Description

technical field [0001] The invention relates to a preparation method of a functional plastic film masterbatch, in particular to a preparation method of a kiwifruit fresh-keeping film masterbatch containing a rare earth complex. Background technique [0002] Actinidia chinensis Planch belongs to Actinidia chinensis Planch, which is a high-grade fruit with high nutritional value, medicinal value and fresh eating rate. The fruit is sweet and sour, delicious and nutritious, especially famous for being rich in vitamin C. It is known as the "king of vitamin C". Kiwifruit has a long history of cultivation in my country. In recent years, with the continuous acceleration of the kiwifruit industry, the planting area and output of kiwifruit in my country have leapt to the first place in the world. However, the production period of kiwi fruit is concentrated, and the fruit is easy to lose water and shrink, soften and rot after harvesting, which greatly limits the development of kiwi fr...

Problems solved by technology

Preservation methods related to new preservatives such as oxalic acid treatment, 1-MCP treatment, ClO 2 Although some progress has been made in processing, etc., it still fails to meet the commercial needs of fresh kiwi fruit preservation, and there are many problems in actual promotion and application.
