Problems solved by technology

Although peony seed is a kind of high oil content oil crop, its oil content is as high as 32% ~ 34%, but peony seed grain is hard, and the existing pressing equipment is used for squeezing peony seed oil and can not reach ideal oil yield and pressing. Effect, for example, the residual oil rate of seed meal with traditional extrusion pressing technology is about 10%, and the residual oil rate of seed meal with screw pressing technology is about 8%.

preparation example Construction

[0021] The invention provides a kind of preparation method of peony seed oil, comprises the following steps:

[0022] 1) Shelling and pulverizing peony seeds to obtain peony seed powder;

[0023] 2) mixing the tree peony seed powder described in step 1) with an aqueous solution of an enzyme preparation, performing enzymolysis to obtain an enzymolysis solution;

[0024] 3) drying and pressing the enzymatic hydrolysis solution in step 2) to obtain peony seed oil.

[0025] The invention dehulls and pulverizes the peony seeds to obtain the peony seed kernel powder. In the present invention, the peony seeds are preferably mature peony seeds (endosperm is fully developed, the seeds are full, and there is no rancidity); the variety of the peony seeds is preferably Fengdan peony seeds; low pros.

[0026] In the present invention, the equipment for shelling is preferably a shelling machine, more preferably a special shelling machine for peony seeds; the special shelling machine for ...

[0035] After dehulling and pulverizing the mature peony seeds, take 10g of α-amylase and dissolve it in 1kg of water, activate it in a constant temperature water bath at 50°C for 15min, mix the activated enzyme preparation aqueous solution with 5kg of peony seed powder evenly, and Enzymolysis at 50°C for 6 hours, setting the temperature of the blast drying oven at 55°C, drying for 6 hours, pressing with a screw press, testing (Xima hand-held infrared temperature measuring gun, model: AS852B) pressing The temperature is 61°C, the pressing times are 2 times, the time is 4.5 min, and the pressing efficiency is 1.11 kg / min. The obtained 1.41 kg oil is peony seed oil, and the oil yield is 28.24%. The residual oil rate of seed meal was detected by Soxhlet extraction method, and the result showed that the residual oil rate of seed meal was 4.8%.

Abstract

The invention provides a preparation method for peony seed oil, and belongs to the technical field of edible oil processing. The method comprises the following steps: 1), shelling and crushing penoy seeds to obtain peony seed kernel powder; 2), mixing the peony seed kernel powder in step 1) and an enzyme preparation aqueous solution for enzymolysis to obtain an enzymolysis solution; 3), drying andpressing the enzymolysis solution in the step 2) to obtain the peony seed oil; the enzyme preparation in the step 2) comprises one or more of cellulase, neutral protease, alkaline protease and alpha-amylase, pectinase and hemicellulase; the pressing temperature in the step 3) is 50-80 DEG C. The method has the advantages of high pressing efficiency, high oil yield and low residual oil rate of seed meal.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a preparation method of peony seed oil. Background technique [0002] Peony seed oil is a new resource food oil. Peony seed oil is rich in alpha-linolenic acid. α-linolenic acid is the basic substance that constitutes cell membranes and biological enzymes, plays a decisive role in human health, and is an essential nutrient that is necessary for human health but generally lacks. Peony seed oil has high health care and medical value. Although peony seed is a kind of high oil content oil crop, its oil content is as high as 32% ~ 34%, but peony seed grain is hard, and the existing pressing equipment is used for squeezing peony seed oil and can not reach ideal oil yield and pressing. Effects, for example, the residual oil rate of seed meal with traditional extrusion pressing technology is about 10%, and the residual oil rate of seed meal with screw pressing technology...
