Problems solved by technology

Because the seed kernels of torreya are wrinkled, the peeling method of extruding and rubbing is easy to cause damage to the appearance of the kernels, and because the kernels are finely wrinkled, it is difficult to remove the wrinkled inner seed coat...

Embodiment 1

[0022] Take 100g of shelled torreya (moisture content about 15-20%) that has been cooked and not dried, and treat it with medium heat (output power about 300w) in a household microwave oven (working frequency 2450±50MHz) for 1.5min. After taking it out, The shell temperature is 60-70°C. The outer shell is more fragile than before treatment, and the inner testa is cracked. The outer shell and inner testa are easily removed by manual stripping.

[0023] The water content of the kernels after the above treatment is still about 10%; this method is suitable for high requirements on the appearance of the kernels and low demand.

Embodiment 2

[0025] The difference from Example 1 is that the processed Torreya torreya is ripe after completion, and the water content after drying is about 8-10%, and the treatment time is changed to 2min; all the other are the same as in Example 1. After the treatment, the inner testa and kernel are dry and brittle. At this time, the water content of the kernel is 5%.

Embodiment 3

[0027] Using intermittent large-scale microwave oven (operating frequency: 2450±50MHZ; cavity size: 840(L)×700(W)×690(H)(mm); material turntable: Φ660mm), every time the shelled Chinese torreya (moisture content) The content is about 15-20%) 5kg, the set power is 6kw, and the processing time is 5min. Take it out after treatment, at this time the inner testa has cracked, then put it into a vibrating sieve, immerse in 90°C water for 5 minutes, the inner testa will expand after absorbing water, and separate from the kernel; Put into the bottom of the water, the kernel can be obtained from the sieve, and the endocarp can be obtained by filtration.

Abstract

The invention discloses a method for removing endopleura from Chinese torreya seeds. The method comprises the following steps: the Chinese torreya seeds are put into microwave equipment and processed by electromagnetic wave at 2450 plus or minus 50MHz or 915 plus or minus 25MHz for 1-7min; the endopleura clinging to kernel cracks after processing of the Chinese torreya seed and the endopleura is removed; and the Chinese torreya seeds have hull or have no hull. The method can help easily and effectively separate the endopleura from the kernel, and can help respectively obtain the endopleura and the kernel which basically keep the original nutrients and active ingredients.

Description

technical field [0001] The invention relates to a pretreatment technology for deep-processing products of agricultural and forestry products, in particular to a technology for removing inner testa of torreya. Background technique [0002] Torreya is the seed of the yew family (Taxaceae) Torreya. Torreya genus in my country includes Torreya yunnanensis, Torreya bashanensis, Torreya longifolia, Torreya vulgaris, etc. Among them, the Torreya tree is the most widely distributed, the longest cultivation history, and the highest economic value in my country. It is mainly produced in the Kuaiji Mountain area of ​​Zhejiang Province, including seedling varieties such as Mi Torreya, Sesame Torreya, Ivory Torreya, Round Torreya, Dayuan Torreya, etc., as well as cultivated varieties. Torreya, Torreya is a rare dried fruit unique to my country because of its delicate kernel texture and crisp flavor. It has become a local famous product as early as the Tang and Song Dynasties.
