Abstract

The invention relates to a mangifera indica fresh-keeping solution containing kieselguhr. The mangifera indica fresh-keeping solution containing kieselguhr is prepared from the following raw material ingredients in percentage by weight: 5-10% of kieselguhr, 0.2-0.5% of citric acid, 0.1-0.3% of cinnamic acid, 0.1-0.2% of chitosan and the balance of distilled water replenished until the total weight percentage is 100%. The mangifera indica fresh-keeping solution containing kieselguhr is used for performing coating preservation on mangifera indica, and is capable of keeping pericarp surfaces of mangifera indica dry, effectively restraining propagation of pathogens, obviously restraining the pericarps of mangifera indica from becoming yellow and restraining fruits of mangifera indica from getting rot, and reliving a fruit after-ripening process. The mangifera indica fresh-keeping solution containing kieselguhr is simple in preparation process, low in production cost, and non-toxic and safe, and conforms to the environmental protection concept.

Description

technical field [0001] The invention relates to the technical field of fruit preservation, in particular to a mango preservation solution containing diatomite. Background technique [0002] Fresh fruit is a necessity in people's life. Timely, fast and high-quality transportation of fresh fruit from the place of production to the place of consumption can not only communicate the economic relationship between urban and rural areas in time, open up product sales, activate the rural economy, and promote agricultural development, but also more It is good to meet the growing demand of urban residents for food. After the fruit is harvested, it still undergoes complex physiological changes, continues to respire and transpirate, and is prone to rot and deterioration, which will affect the quality and sales of fruits and vegetables. [0003] Mango is a typical tropical fruit, known as the "King of Tropical Fruits", and is currently the fifth most produced fruit in the world. However...
