Abstract
The invention belongs to field of deep processing of farm products, in particular to peony seeds albumen and its extracting method：Peony seeds albumen and its extracting method：After peony seeds shelling, shell is separated with benevolence, then by benevolence by broken, after preheating, peony seed oil is separated using supercritical extraction, remainder is the peony seeds dregs of rice, the peony seeds dregs of rice powder separated is dried, it crushes, the distilled water of certain mass ratio is then added, after high-speed homogenization, NaOH solution is added and is adjusted to suitable ph, stirring and leaching certain time under the conditions of 40-60 DEG C, leaching liquor is centrifuged, collect supernatant, obtain tree peony protein solution, then tree peony protein solution pH value is adjusted to acidity with HCl solution again, the tree peony albumen precipitated, it is centrifuged and washs to neutrality, it is dried to obtain peony seeds albumen.This method extracting method is simple and fast, at low cost, is conducive to industrialization production, the molecular weight of gained peony seeds albumen is mainly in 10-30ku, it is necessary to which amino acid content is high, and nutritive value is high.
Description
Technical field
The invention belongs to field of deep processing of farm products, in particular to peony seeds albumen and its extracting method.
Background technique
Tree peony has permanent plantation history in China, and oil has good economic, ecology and social benefit with tree peony, energetically
Development oil can not only make full use of forest land resource abundant with tree peony industry, effectively increase in the case where not striving ground with peasant
Food plant oil yield, maintenance national food and oil safety optimize national diet structure, improve health conditions.And life can be improved
State environment promotes economic development, increases farmers' income.Oil can produce 3000~3500kg/hm of seed with tree peony2, peony seed oil 600 out
~700kg/hm2, benefit per mu is more than 5000 yuan, and compared with traditional grain and oil crop, benefit is plant cereal crops 8~10
Times.Oil is an important economic tree with tree peony, and development oil is with tree peony industry for improving farmers' income, peasant being helped to shake off poverty
It gets rich and is of great significance.However it is also less to the comprehensive utilization of peony seeds at present, peony seeds mention the grouts after oil, contain high egg
It is white, it is a kind of novel plant albumen leaved for development.
Summary of the invention
The present invention provides peony seeds albumen and its extracting methods, and steps are as follows：
(1) after peony seeds shelling, shell is separated with benevolence, then by benevolence after broken, preheating, using overcritical extraction
Separation peony seed oil is followed the example of, remainder is the peony seeds dregs of rice, and the peony seeds dregs of rice powder separated is dried, and is crushed；
(2) distilled water of 10-15 times of mass ratio, high-speed homogenization are added in the tree peony benevolence powder that step (1) obtains；
(3) NaOH solution is added in the homogenate obtained by step (2) to be adjusted to pH is 8.8-10.0, under the conditions of 40-60 DEG C
Stirring leaching 1-2h, collects filtrate；
(4) dilute HCl solution is added in step (3) by tree peony protein solution pH value to 4.5-5.5, the tree peony precipitated
Albumen；
(5) mixture obtained by step (4) is centrifuged, sub-cloud precipitating, and washed to neutrality, be dried to obtain peony seeds
Albumen.
The beneficial effects of the present invention are：This method extracting method is simple and fast, at low cost, is conducive to industrialization production, institute
The molecular weight of peony seeds albumen is obtained mainly in 10-30ku, it is necessary to which amino acid content is high, and nutritive value is high.
Detailed description of the invention
Fig. 1 is influence of the pH to peony seeds protein extracting ratio in the embodiment of the present invention 1.
Fig. 2 is the amino acid analysis result of peony seeds albumen in the embodiment of the present invention 1.
