Embodiment Construction

[0035] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0036] A method for fresh-keeping fresh wet walnuts without belt shells at room temperature, the specific method steps are as follows:

[0037]1. Put the fresh walnuts without the green belt shell into the special hydrogen-excited fresh-keeping device, the effective concentration of hydrogen is 5ppm-50ppm, the treatment time is 0.5h-10h, and the nonaldehyde solution (5ppm-50ppm) is steam sprayed and fumigated for 0.5h-1h;

[0038] The structure of the special hydrogen-excited fresh-keeping device is as follows: figure 1 As shown, it includes a hydrogen generator 3, an ultrasonic humidifier 2 and a processing cabinet 1. The hydrogen generator is connected to an ultrasonic humidifier, and the ultrasonic humidifier is connected to a processing ...

Abstract

The invention relates to a normal-temperature logistics fresh-keeping method for fresh and wet walnuts without shells, which is scientific and reasonable in design, efficient in use and remarkable in fresh-keeping effect. Hydrogen excitation fresh-keeping treatment, three-dimensional passivation treatment, a novel controlled atmosphere fresh-keeping process, equipment and packaging are utilized, and the fresh-keeping technical problems of water return, walnut kernel browning, shell and kernel mildewing and the like occurring in the normal-temperature storage process of the fresh walnuts are comprehensively and efficiently solved. The fresh walnuts obtained by the method have brighter kernels, fuller pulp and better taste, and compared with the traditional technology, the fresh walnuts are stored at normal temperature for 15 days, and various evaluation indexes such as appearance, taste and nutrition are remarkably improved. The method is suitable for multiple scenes such as direct normal-temperature logistics sales after walnut harvesting or normal-temperature logistics after cold storage for a certain time. Compared with existing similar technical products, after fresh walnuts are stored at the normal temperature for 15 day, the mildewing of fresh walnuts is avoided, and the weight loss rate thereof is smaller than 3.1%. the brown stain is low, the taste is fresh and not greasy, and the like.

Description

technical field [0001] The invention belongs to the field of fresh-keeping processing, and relates to a logistics preservation technology at normal temperature, in particular to a fresh-keeping method of fresh-wet walnuts without belt shells at normal temperature. Background technique [0002] my country's walnut planting area and output rank first in the world. Compared with dried products, the unique quality and flavor of fresh walnuts have gradually become a new trend of consumption. However, the fresh-wet walnuts, which are mainly fresh-keeping with green skin and peeled off the shell, are difficult to keep fresh. They are stored at room temperature and stored on the surface of the shell, which is wet, sticky, and prone to mildew. The seed coat is easy to brown and loses water and weight significantly (15 %-30%), oil oxidation and hardening and other technical problems of room temperature preservation. [0003] At present, fresh walnut fresh-keeping technologies are mos...
