Embodiment 1

[0030]A preparation method of peeled and detoxified peach kernels comprises the following steps:

[0031] (1) Dehulling: The dried wild peach kernels are peeled with the improved HAS-200 type apricot kernel peeling machine. By adjusting the feeding baffle and the distance between the double rollers, the fruit with a whole fruit rate of more than 95% can be obtained. peach kernel;

[0032] (2)Na 2 S 2 o 5 Soaking: get the complete peach kernel gained in step (1) and put it into Na with a mass fraction of 0.06‰ 2 S 2 o 5 Soak the solution at room temperature for 2 to 5 hours, then remove the peach kernels and rinse off the residual Na 2 S 2 o 5 , to obtain light white leather and clean peach kernels, this step can reduce the pollution of impurities and colors to the lye in the next step;

[0033] (3) Alkaline peeling: take the peach kernel obtained in step (2) and put it into Na 2 CO 3 and CaCl 2 The mixed solution was treated at 70° C. for 20 minutes to obtain soft-...

Abstract

The invention provides a preparation method of skin-removed and detoxified peach kernels, and the preparation method can produce high-yield peach kernel pulp by using Na2(subscript)CO3(subscript) andCaCl2(subscript) combination in peach kernel skin-removing alkaline solution; calcium ions are used to harden the peach kernels in the solution to prevent the peach kernels from softening; and the peach kernels are debitterized and detoxified by citric acid with a mass percentage of 0.15%-0.25% to achieve ideal skin removal and detoxification.

Description

technical field [0001] The invention belongs to the technical field of food pretreatment and processing, and in particular relates to a preparation method of peeled and detoxified peach kernels. Background technique [0002] The peach kernel referred to in the present invention is the dried mature seed of the Rosaceae Prunus plant light walnut (wild peach) (Amygdalus mira KoehneKov et.Kpst), which is mainly produced in Nyingchi, Qamdo, Tibet and Limu County, Sichuan. It is a common Chinese medicinal material, which has the effects of promoting blood circulation and removing blood stasis, moistening the intestines and laxative, relieving cough and asthma. The annual output of light walnuts (wild peaches) in Tibet is nearly 7,000 tons. At present, except for a small amount used in traditional Chinese medicine, most of them have not been utilized. The main components of peach kernels are oil and protein, of which the protein content accounts for about 25%, and the oil content ...
