Effect test

Embodiment 1

[0028] Taking Fupingjian persimmon as the test material, the ozone concentration was 4 mg m in the comparative experiment when ozone was sterilized. -3 , 5mg m -3 , 6 mg m -3 , 7mg m -3 and 8 mg m -3 The bactericidal effect of:

[0029] the concentration of ozone Sterilization rate 4mg m -3 80％ 5mg m -3 95％ 6mg m -3 80％ 7mg m -3 70％ 8mg m -3 65％

[0030] Based on the above five sets of results, it can be concluded that during ozone sterilization treatment, the concentration of ozone is 5-7 mg m -3 It is advisable to take 5 mg m -3 better.

Embodiment 2

[0032] Taking Fupingjian persimmon as the test material, the storage period of persimmon fruits at 0°C, 0.5°C, 1°C, 1.5°C, 2°C, 2.5°C and 3°C was compared. The results are as follows:

[0033] Refrigeration temperature (℃) Storage period (days) 0 100 0.5 107 1 124 1.5 125 2 109 2.5 77 3 65

[0034] This embodiment two shows:

[0035] The storage period of persimmon fruits stored at 0~2℃ can meet the general storage requirements, and the storage period of persimmon fruits stored at 1~1.5℃ has the longest storage period and the best effect.

[0036] The storage period of persimmon fruits stored at 2.5~3℃ was obviously shortened, which was only half of the storage period at 1~1.5℃.

Embodiment 3

[0038] Taking Fupingjian persimmon as the test material, the relative humidity of the cold storage was 80%, 85%, 90%, 95% and 98% when the refrigeration temperature was 1 °C in the comparative experiment, and the relative humidity of the cold storage was 80%, 85%, 90%, 95% and 98% respectively. Five groups of storage effects, the results are as follows:

[0039] Relative humidity Weight loss rate 80％ 5.6％ 85％ 2.7％ 90％ 2.1％ 95％ 2.5％

98％

4.8％

[0040] According to the experiment, it can be concluded that:

[0041] When the relative humidity of the cold storage is kept at 85-95%, the weight loss rate of persimmon fruit is lower, and the storage effect is better, and the effect is the best when the relative humidity is 90%.

Abstract

The invention relates to a method for storing persimmons. Well-developed persimmons without mechanical damages are selected; ozone sterilization is carried out to fresh fruits selected and the concentration of ozone is 4 mg question mark m<-3> to 8 mg question mark m<-3>; the persimmons are precooled to 1 DEG C to 5 DEG C and then put into packaging bags with a thickness of 0.03mm to 0.08mm and sealed; and the persimmons packed and sealed are stored in a refrigeratory at 0 DEG C to 2 DEG C for cold storage. The method solves the technical problems of high damage ratio in the fruit quality and poor cold storage effect when cold storage is carried out to the persimmons. The method can restrain the browning of the fruits with low quality damage ratio, thus being capable of realizing long time storage while preserving both quality and freshness so as to adjust market demand.

Description

technical field [0001] The invention relates to a method for storing fruits, in particular to a method for storing persimmon fruits. technical background [0002] Persimmon is rich in nutrients, containing protein, fat, pectin and a variety of vitamins and minerals. Persimmon also has high medicinal value. According to the "Compendium of Materia Medica": "Persimmon is the fruit of the blood of the spleen and lung, and its taste is sweet. The Qi is flat, the nature is astringent and can be absorbed, so it has the power of strengthening the spleen, astringing the intestines, and stopping bleeding." However, during the ripening process of persimmon fruit, the hardness will decrease and the pulp will soften, which is an important factor limiting the long-term storage of persimmon. Therefore, how to control the fruit softening and prolong the storage period of persimmon has become an urgent problem to be solved. [0003] At present, low temperature storage is one of the most ef...
