Problems solved by technology

Pears are the "family of all fruits". Because of their tenderness, juiciness, sweet and sour taste, they are also known as "natural mineral water". The current production of pears has developed from scattered distribution to large-scale production bases. Fresh food and processed The combination of juice production, expansion of domestic sales, and expansion of overseas markets have a good development trend. At present, the transportation of pears mainly relies on bagging and then packaging with foam nets to prevent pears from being damaged due to collisions during transportation and handling. , but because the foam net is a structure with openings at both ends, and the thickness is average, the effect of preventing transportation damage is average

Embodiment 1

[0017] A fresh-keeping and anti-collision packaging method for pears during transportation, comprising the following steps:

[0018] (1) Mix carrageenan with polyacrylamide, sodium D-gluconate, calcium dihydrogen phosphate, and sodium bicarbonate in a weight ratio of 100:3:5:1:1, and add walnuts in a volume ratio of 1:10 Skin extract, heated to 80°C, kept stirring at a stirring rate of 3000r / min for 23 minutes to obtain a stable colloidal solution;

[0019] When preparing the walnut skin extract, mix walnut skin and water at a volume ratio of 1:7 and heat to 90°C, vacuumize until the vacuum degree reaches 2MPa, and reflux for 2 hours to obtain the walnut skin extract liquid;

[0020] (2) Pass the colloidal solution into the granulation model to granulate. The granulation diameter is 0.1cm to obtain spherical particles. The spherical particles are dried under hot air at 45°C until the water content is 15%;

[0021] (3) Put the freshly harvested pears into the packaging bag, a...

Abstract

The invention relates to a vegetable and fruit freshness retaining treatment method, in particular to a freshness retaining anti-collision package method in the pear transport period. Carrageenan, polyacrylamide, D-sodium gluconate, monocalcium phosphate and sodium bicarbonate are mixed and are added into walnut peel leach liquor, after heating and stirring, the mixed liquor is led into a granulation model for granulation, freshly-harvested pears are put into a package bag, spherical particles are added, distilled water and mixed gas are led into the package bag, and bag sealing is carried out. The package method has the good anti-collision, freshness retaining and color protecting effects.

Description

technical field [0001] The invention relates to a fresh-keeping treatment method for fruits and vegetables, in particular to a fresh-keeping anti-collision packaging method for pears during transportation. Background technique [0002] Pears are known as "the family of all fruits". In the world fruit market, apples, pears and oranges are known as the "three major fruit tyrants". my country is one of the origins of the Pear family. Among the 25 species of the Pear family, there are 14 species in my country, accounting for more than half of the total. It is the country with the most varieties of pear trees in the world. With the increase of my country's pear production year by year and the substantial improvement of people's living standards, pears have become a daily fruit in common people's families. Pears are the "family of all fruits". Because of their tenderness, juiciness, sweet and sour taste, they are also known as "natural mineral water". The current production of p...
