Problems solved by technology

However, the strawberry peel is thin and has a large water content. It is a non-respiratory climacteric fruit with a very short postharvest life. Due to the high temperature and rain in the harvest season, the postharvest fruit has a large water content, a strong metabolism, and is sensitive to fungi. Mechanical damage and infiltration of germs lead to rot and loss of commodity value. It can only be stored for 1-2 days at room temperature. How to prolong the storage and preservation time of strawberries, maintain the nutritional content to the maximum extent, and reduce the rot rate has become the key to the production and sales of strawberries. question
[0003] At present, strawberry fresh-keeping technologies mainly include low temperature, film packaging and preservative treatment. However, due to problems such as short storage time, complicated film packaging operations, and chemical residues in preservatives, the development of the industry is limited, and it also causes huge losses for strawberries after harvest.

Embodiment 1

[0016] A high-efficiency fresh-keeping method for fresh strawberry fruit, comprising the steps of:

[0017] a), harvest eight to nine mature strawberries, and select strawberries with uniform size, no pests and diseases, and mechanical damage;

[0018] b) Soak the strawberries in a preservative for 10 minutes, pick up the strawberries and drain, and dry in the air. The preservative includes 10 parts by weight of tea polyphenols, 0.3 parts by weight of perilla leaf distillate, and 0.5 parts by weight of calcium chloride , 50-100 parts by weight of distilled water;

[0019] c), after the dried strawberries are packed in a film bag, they are stored in a cold storage where the ambient temperature is 4° C. and the relative humidity is 80-95%.

[0020] The above perilla leaf distillate is prepared as follows: soak the perilla leaves for 1 to 3 hours, steam distill for 4 to 6 hours, and extract the volatile oil; filter with three layers of gauze to remove the medicinal residues, and...

Embodiment 2

[0023] The efficient fresh-keeping method of strawberry fresh fruit comprises the following steps:

[0024] a), harvest eight to nine mature strawberries, and select strawberries with uniform size, no pests and diseases, and mechanical damage;

[0025] b) Soak the strawberries in a preservative for 10 minutes, pick up the strawberries and drain, and dry in the air. The preservative includes 5 parts by weight of tea polyphenols, 0.1 parts by weight of perilla leaf distillate, and 0.01 parts by weight of calcium chloride , 50 parts by weight of distilled water;

[0026] c), after the dried strawberries are packed in a film bag, they are stored in a cold storage where the ambient temperature is 4° C. and the relative humidity is 80-95%.

[0027] Using the fresh-keeping method of this embodiment, the loss rate of fresh strawberry fruit is more than 5% after storage for 53 days, and the fruit just begins to grow mold.

Embodiment 3

[0029] The efficient fresh-keeping method of strawberry fresh fruit comprises the following steps:

[0030] a), harvest eight to nine mature strawberries, and select strawberries with uniform size, no pests and diseases, and mechanical damage;

[0031] b) Soak the strawberries in a preservative for 10 minutes, pick up the strawberries and drain, and dry in the air. The preservative includes 14 parts by weight of tea polyphenols, 0.5 parts by weight of perilla leaf distillate, and 1 part by weight of calcium chloride 100 parts by weight of distilled water;

[0032] c), after the dried strawberries are packed in a film bag, they are stored in a cold storage where the ambient temperature is 4° C. and the relative humidity is 80-95%.

[0033] Using the fresh-keeping method of the present embodiment, the loss rate of strawberry fresh fruit exceeds 5% after storage for 50 days, and the fruit just begins to grow mold.

Abstract

The invention discloses an efficient preservation method of fresh strawberries. Preservative for use comprises, by weight, 5 to 14 parts of tea polyphenol, 0.1 to 0.5 part of Perilla leaf distillate, 0.01 to 1 part of calcium chloride, and 50 to 100 parts of distilled water. The Perilla leaf distillate and the tea polyphenol in the preservative are both preserving agents extracted from natural plants, having strong bacteriostatic action on various bacteria and ensuring safety and non-toxicity. The calcium chloride added to the preservative helps improve hardness of the strawberries and is good for preservation of the strawberries.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a high-efficiency preservation method for fresh strawberries. Background technique [0002] Strawberry belongs to Rosaceae and is an evergreen herbaceous plant for many years. Strawberry fruit is bright in color, unique in flavor and rich in nutrition. It has the medicinal effect of purging, and has certain effects in antibacterial, anti-tumor and anti-HIV viruses. However, the strawberry peel is thin and has a large water content. It is a non-climacteric fruit with a very short postharvest life span. Due to the high temperature and rainy season during the harvesting season, the postharvest fruit has a large water content, strong metabolism, and is sensitive to fungi. Mechanical damage and infiltration of germs lead to rot and loss of commodity value. It can only be stored for 1-2 days at room temperature. How to prolong the storage and preservation time of...
