Embodiment 1

[0028] Take 200 parts by mass of chitosan powder as a biological information substance, and 1 part by mass of abamectin as a biopesticide to prepare a vegetable bioinformation substance, and add water to prepare a solution with a mass concentration of 0.8% of the fruit and vegetable bioinformation substance. Chitosan is soaked in hydrochloric acid with a mass concentration of 10 by the shrimp shell to remove inorganic salts in the shell for about 24 hours, and then boiled with a 40% sodium hydroxide solution for about 0.5 hour to remove the shell collagen. Then use 70% alkali to remove the acetyl group for about 4 hours, dry and pulverize to prepare chitosan.

Embodiment 2

[0030] Take 800 parts by mass of chitosan powder as biological information substance, and 1 part by mass of biopesticide abamectin to prepare the biological information substance of fruits and vegetables, and add water to prepare a solution with a mass concentration of 0.8% of functional antistaling agent during use. Chitosan is soaked in hydrochloric acid with a mass concentration of 15% by the crab shell for about 20 hours to remove inorganic salts in the shell, and then boiled with a 30% sodium hydroxide solution for about 0.7 hours to remove the shell collagen protein, and then use 75% alkali to remove acetyl group for about 3 to 5 hours, dry and pulverize to prepare chitosan.

Embodiment 3

[0032]Take 15 parts by mass of chitosan powder as a biological information substance, and 1 part by mass of abamectin as a biological insecticide to prepare the biological information substance of fruits and vegetables, and add water to prepare a solution with a mass concentration of 0.8% as a functional antistaling agent during use. Chitosan is soaked in hydrochloric acid with a mass concentration of 20% by the crab shell for about 12 hours to remove inorganic salts in the shell, and then boiled with a 35% sodium hydroxide solution for about 0.5 hour to remove the shell collagen , and then use 75% alkali to remove the acetyl group for about 3 to 4 hours, dry and pulverize to obtain chitosan.

Abstract

The invention provides a fruit-vegetable biological information substance consisting of a biological information substance and a biotic pesticide. The fruit-vegetable biological information substance is mainly prepared by chitosan, thus being an ideal green fruit-vegetable biological information substance which generates no harm to human health in production and use processes, and does not contain carcinogenic substance components prohibited for use in environmental protection nor contain other pollutant; the fruit-vegetable biological information substance has the functions of enlarging mango fruits to improve mango output, increasing maturity and reducing rotting rate in sales, and reducing chemical pesticide residues; and the fruit-vegetable biological information substance also can improve the quality of the mango fruit simultaneously when improving output, thus achieving the effects of nutrition and health care. Besides, the fruit-vegetable biological information substance has the characteristics of simple method, low cost price, high operability and easy implementation, thus being capable of achieving good economic and social benefits.

Description

technical field [0001] The invention relates to extracting plant information substances from environmental waste, and artificially activating the defense force of crops before the plants are harmed or aging, so as to increase the output and quality of the crops. It also belongs to the technical field of chitosan. Background technique [0002] Fruit is rich in nutrition and is a favorite snack food for people. Research by medical experts has shown that people who eat more fruits have a relatively small proportion of suffering from heart disease, cancer, stroke and diabetes. However, because fruits are restricted by nature and have obvious seasonal and regional characteristics, this is in contradiction with people's consumption demand for fruits throughout the year. Moreover, fruits suffer serious losses due to the influence of physical, physiological and pathological factors after harvesting. According to investigations, the postharvest loss rate of fruits and vegetables in...
