Problems solved by technology

Among them, the purchase and maintenance costs of physical fresh-keeping equipment such as low-temperature storage and controlled-atmosphere storage are high; chemical preservatives are mostly synthetic chemicals, which have problems such as low safety, large residues, and large side effects.
Although the chemical preservatives mainly used in the market are efficient and cheap, they have certain potential toxicity, and the main methods of use are dipping, smearing, etc. The direct contact between the preservative and strawberries will cause the preservative to remain on the surface of the strawberry, affecting consumers. food safety

Embodiment 1

[0013] Material preparation: prepare isoamyl salicylate, straws, cardboard with a thickness of 0.3 cm, strawberries and several plastic boxes with a capacity of 1.5 liters;

[0014] Preservation card preparation: Cut the cardboard into a 4*4 cm square, weigh 200 mg of isoamyl salicylate with a straw and fill it on the surface of the cardboard to make a preservation card.

[0015] Experimental test: select 100 strawberries and 10 plastic boxes, divide the strawberries into 10 groups and place them in the plastic boxes respectively, put the fresh-keeping card prepared in this example in each plastic box, and store them in a sealed manner. Placed under the same conditions for 10 days, samples were taken every 2 days during storage to determine the decay index, weight loss rate and vitamin C (Vc) content of strawberry fruit.

[0016] Calculation method of direct rot:

[0017] The weight loss rate was determined by weighing method: weight loss rate = (fruit mass before storage -...

Embodiment 2

[0022] Material preparation: prepare isoamyl salicylate, straws, flannelette with a thickness of 0.3 cm, strawberries and several plastic boxes;

[0023] Preservation card preparation: cut the flannelette into 4*4 cm squares, weigh 300 mg of isoamyl salicylate with a straw and fill it on the surface of the flannelette to make a preservation card.

[0024] Antiseptic effect test: the method is the same as in Example 1, except that the fresh-keeping card made in this example is used for the fresh-keeping card.

[0025] The experimental data are as follows:

Abstract

The invention discloses preparation and application of an external control type strawberry fresh-keeping card taking food spice isoamyl salicylate as an effective component, relates to the technical field of fruit and vegetable fresh-keeping, and in particular relates to an external control type fresh-keeping card prepared by adding isoamyl salicylate to a carrier material. The volatile isoamyl salicylate gaseous molecules have preservative and fresh-keeping effects on strawberries, so that the fresh-keeping time of strawberry fruits in the storage process can be prolonged, the rotting rate and the nutrient loss are reduced, and the quality and the appearance of the strawberries are kept. The isoamyl salicylate used in the invention is a food spice allowed to be used in the national standard, is prepared into the fresh-keeping card for strawberry fresh-keeping, and has the advantages of safety, environmental protection, convenience in use and low cost.

Description

technical field [0001] The invention relates to the technical field of strawberry storage, in particular to a preparation method and application of an externally controlled strawberry fresh-keeping card. Background technique [0002] Strawberry fruit is bright in color, sweet and juicy, rich in nutrition, and has a high demand in the fruit market. Because strawberry pulp is soft and tender, it is susceptible to microbial infection and damage during transportation, and it is difficult to keep fresh and store and transport, resulting in huge economic losses and waste of resources. How to prevent strawberry fruit from rotting and deteriorating after picking, and keep its nutritional components and color, fragrance and taste unchanged, is a major problem affecting the supply and consumption of strawberries. At present, the commonly used strawberry postharvest preservation techniques include physical measures and preservative treatment. Among them, the purchase and maintenance ...
