Embodiment 1

[0027] Embodiment 1: prevent the storage method of drying Xinjiang Wen No. 185 thin-skinned walnuts from rancidity

[0028] Taking into account factors such as the rigor of scientific research, operability in production practice and ease of application, it has been proved by experiments. For details, see the attached figure 1 , the storage method to prevent dry Xinjiang Wen 185 thin-skinned walnuts from rancidity is as follows:

[0029] Select Xinjiang Wen No. 185 thin-skinned walnuts at relative humidity mass percentages of 30-40%, 40-50%, 50-60%, and 60-75%, and the temperature is normal temperature, 15°C±0.5°C, 10°C±0.5°C, 5°C ℃±0.5℃ at different temperatures, and the packaging environment is breathable cloth bag packaging, vacuum packaging, spontaneous modified atmosphere MA packaging, 100% volume percentage carbon dioxide packaging, and 100% volume percentage nitrogen packaging. The influence of three different aspects on the storage quality of thin-skinned walnuts, the ...

Embodiment 2

[0031] Example 2: Effects of different gas environments on storage quality of Wen 185 thin-skinned walnuts

[0032] Experimental design: According to the experimental design during storage, the samples were stored with 5 kinds of gas treatment.

[0033]Treatment 1: storage with ventilation, packed in cotton bags with good ventilation; treatment 2: storage in vacuum packaging, packaging in food vacuum bags and vacuum treatment; treatment 3: packaging and storage in 100% carbon dioxide, packaging in food vacuum bags and Inject CO after evacuation 2 ;Treatment 4: 100% nitrogen packaging and storage, food vacuum bag packaging and vacuum treatment, inject N 2 ; Treatment 5: MA package storage, food vacuum bag packaging, leaving a certain amount of air in the bag. The vacuum bag is made of nylon (NL) + polyethylene (PE) + polyester resin (PET) produced by Suzhou Jiasheng Packaging Materials Co., Ltd., with a thickness of 0.2mm. 30 bags for each of the 5 treatments, 1kg per bag. ...

Embodiment 3

[0045] Example 3: Effects of different storage methods on the membrane lipid antioxidant enzyme activity of Wen 185 thin-skinned walnut

[0046] Experimental method: The walnuts were stored at room temperature using five storage methods with different gas conditions, including breathable cloth bag packaging, vacuum packaging, MA (spontaneous modified atmosphere) packaging, 100% carbon dioxide packaging, and 100% nitrogen packaging. Malondialdehyde (MAD), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), peroxidase (POD) content was determined.

[0047] In the assay method, the mensuration of glutathione peroxidase adopts spectrophotometry, the mensuration of superoxide dismutase (SOD) adopts spectrophotometry, the mensuration of peroxidase adopts spectrophotometry, and the mensuration of catalase adopts spectrophotometry. The titration method was used for the determination, and the spectrophotometric method was used for the determination of malondia...

Abstract

The invention discloses a storage method for preventing a dried Xinjiang Wen 185 thin-skin walnut from rancidity. Research that temperature, relative humidity and gas components are key technical factors influencing the storage quality of the thin-skin walnut is started, the controllability of production operation of the Xinjiang thin-skin walnut is considered, and the storage temperature and the gas components are researched on the premise of certain relative humidity, so that the key problems of oxidative rancidity such as flavor change, color and lustre browning and nutritional quality reduction during the storage period of the Xinjiang thin-skin walnut are regulated and controlled; the storage temperature is controlled to be 4.5-5.5 DEG C under the relative humidity of 50-60%; a 100% carbon dioxide packaging environment is adopted; the technical research of a storage period quality regulation and control technique is developed; a reasonable storage technological process and a basic technological parameter are determined; the storage method for preventing the dried Xinjiang Wen 185 thin-skin walnut from the rancidity is provided; a good technical effect is achieved; and the storage method has an important actual development value.

Description

field of invention [0001] The invention relates to the technical field of storage and preservation, in particular to the technical field of storage for preventing oxidative rancidity of Xinjiang dried thin-skinned walnuts. Background technique [0002] Walnut, also known as walnut, Qiang peach, and long live seed, belongs to the Juglandaceae Juglans plant. Walnuts have been considered as a high-quality brain food since ancient times. Many of its ingredients can improve the metabolic balance of the brain, improve the biofilm function of nerve cells, reduce blood viscosity, have the effects of scavenging free radicals, anti-aging, and inhibit the body's metabolism. Lipid peroxidation. Xinjiang is one of the main walnut producing areas in my country, and walnut is one of the main economic forest species in Xinjiang. Xinjiang walnut kernels are fine and crisp, rich in fragrance, high in oil content, and of excellent quality. The main varieties of walnut planted in Xinjiang ar...
