Embodiment 1

[0031] Embodiment 1: the modified atmosphere fresh-keeping method of small white apricot

[0032] The invention provides a modified atmosphere preservation method for small white apricot, which specifically adopts the following technical steps:

[0033] (1) Pre-cooling treatment: picking the small white apricot fruit with slightly hard pulp and not fully ripened, and pre-cooling by wind temperature at 3°C ​​until the final fruit temperature is 12±2°C to stop the pre-cooling.

[0034] (2) Modified atmosphere packaging preservation: carry out modified atmosphere packaging under the condition of the final fruit temperature of 12±2°C, put the small white apricot fruit into the packaging bag, and fill it with O 2 and CO 2 Mixed gas, the volume ratio of the fruit volume in the packaging bag to the gas volume is 1:3 to 1:6.

[0035] (3) Cold storage: After the packaging is completed, the temperature is gradually lowered to 8±1°C and stored in a cold storage.

Embodiment 2

[0036] Example 2: Pre-experiment of modified atmosphere fresh-keeping method for small white apricot

[0037] 1. Pre-cooling treatment

[0038] The apricot fruit used in the test is 7-8 maturity, and the post-harvest storage temperature should not be too low to avoid strong glycolytic metabolism, which will cause softening of the pulp, increase of soluble sugar, and loss of aroma and flavor. After the fruit is harvested, the air temperature is 3°C to pre-cool the fruit until the final fruit temperature is 12±2°C to stop the pre-cooling. At this temperature, the modified atmosphere packaging is completed according to the processing settings of each test. After the packaging is completed, the temperature is gradually reduced to 8±1°C to 6# cold storage storage.

[0039] 2. Processing settings

[0040] Set 4 packaging treatments of different air permeability film materials, design O 2 The upper and lower limits of the ratio are 5% to 10%, CO 2 The upper and lower limits of th...

Embodiment 3

[0070] Example 3: Orthogonal optimization method of modified atmosphere preservation of small white apricot

[0071] A single factor experiment was designed to explore the volume ratio of fruit to gas, O 2 Concentration, CO 2 The effect of concentration on the good fruit rate of small white apricot after storage and preservation for 15 days. On the basis of the single factor experiment, a three-factor three-level orthogonal experiment was carried out. The factors and levels of the orthogonal experiment are shown in Table 6.

Abstract

The invention discloses a modified atmosphere fresh-keeping method for small white apricots. The purpose of fresh-keeping is achieved through the steps of pre-cooling treatment, modified atmosphere packaging, and cold storage. The material of the modified atmosphere packaging bag is any one of PP material and PET material. The ratio of the fruit volume in the bag to the gas volume is 1:3~1:6, and the O in the mixed gas of the modified atmosphere packaging 2 The gas concentration is 8%~10%, CO 2 The gas concentration is 2%~4%; the good fruit rate of the provided fresh-keeping method can still reach 80% after 25-30 days of storage, and the fruit has obvious deterioration, while the good fruit rate of CK is lower than 80% after 15 days of storage. %, obvious deterioration appeared, indicating that modified atmosphere packaging prolongs the storage period of small white apricot by 10-15 days, which is about double the time. , the modified atmosphere packaging began to have symptoms of microbial diseases 30 days after harvest.

Description

technical field [0001] The present invention mainly relates to the technical field of food preservation, in particular, the present invention relates to the technical field of apricot preservation. Background technique [0002] Xiaobai apricot belongs to the Central Asian group of common apricot (Prunus armeniaca L.), and is one of the most regionally characteristic Xinjiang melons and fruits. It is native to Xinjiang and only distributed and planted in Xinjiang. Compared with other common apricot varieties on the market, such as Liao apricot and Siberia apricot, the oily apricot type of small white apricot fruit has more than double the sugar content, nearly twice the malic acid content, and the skin is glabrous or short-haired. Thin and smooth, the flesh is delicate, sweet and sour, and it has been verified by experiments that it belongs to drupe fruit and climacteric fruit. Due to the physiological characteristics of small white apricot itself, it is extremely difficult ...
