[0040] 1) Preparation of sample solution

[0041] Accurately weigh 1.0 g of protein product, add appropriate amount of distilled water to make a 5% solution, add 0.1 g of papain, fully hydrolyze in a water bath at 50°C for 1.0 h, and then lyophilize. Add 20.0 mL of methanol to the lyophilized protein, and ultrasonic bath for 20 min. Take 0.5 mL of the standing supernatant and perform silica gel column chromatography to remove impurities, using petroleum ether-diethyl ether (v / v 8:2) as the eluent, and collect the liquid obtained through the column. Dry the liquid with nitrogen flow, dissolve it in 1.5 mL of methanol, pass it through a 0.22 μm organic membrane in an ultrasonic bath for 5 min, and store the obtained filtrate in a refrigerator for later use.

[0042] 2) Drawing of CBD standard curve

[0043] Use Merck C18 column, Waters2487 high-performance liquid chromatograph to measure. The conditions used are as follows: the wavelength is 220nm, the column temperature is 2...

Embodiment 1

[0047] Get denatured hemp meal 2.0kg (this denatured hemp meal is the by-product in the process of extracting hemp oil at high temperature, the main component protein content is 63.69%, fiber content is 13.52%, fat content is 1.09%), is placed in stainless steel tank, according to material Add 20.0L of industrial water at a liquid ratio of 1:10 (Kg / L), and stir mechanically at room temperature to mix evenly. While stirring, NaOH lye with a mass concentration of 10% was added until the pH value was 9.0, and the stirring was continued at room temperature for 40 min. Then transfer to a vertical colloid mill, and carry out 20min grinding process at a rotating speed of 4000r / min. The above-mentioned feed liquid is transferred into the jet cooker system, and the processing temperature is set at 130° C., and the processing time is 120 s. Then transfer to a horizontal centrifuge with a temperature of 25° C. and a rotational speed of 3000 r / min for 20 minutes of centrifugation. The s...

Embodiment 2

[0052] Take 1.0kg of denatured hemp meal, put it in an aluminum tank, add 15.0L of industrial water according to the material-to-liquid ratio of 1:15 (Kg / L), and manually stir and mix evenly at room temperature. Add 10% lye while stirring until the pH value is 9.5, and keep stirring at room temperature for 45 minutes. Then transfer to the split type colloid mill, and carry out 20min grinding process at a rotating speed of 4500r / min. The above feed liquid is transferred into the jet cooker system, the processing temperature is set at 135°C, and the processing time is 120s. Then transfer to a horizontal centrifuge with a temperature of 25° C. and a rotational speed of 3000 r / min for centrifugation for 15 minutes. The supernatant was transferred to a stainless steel ultrafiltration membrane system with a membrane pore size of 100nm for ultrafiltration at 35°C, the inlet pressure was 0.3MPa, the outlet pressure was 0.3MPa, and the flow rate of the permeate was 2.0L / min for cyclic...

Abstract

The invention discloses CBD (cannabidiol)-rich fructus cannabis concentrate protein powder and a preparation method thereof. According to the preparation method, denaturated fructus cannabis meal is taken as a raw material, and protein of the denaturated fructus cannabis meal is preliminarily extracted through the dissolution action of alkaline liquor to protein; the denaturated fructus cannabis meal dissolved in the alkaline liquor is ground by a colloid mill; after the denaturated meal is ground, a spray digester is used for performing thermal treatment on the denaturated meal; after thermal treatment of the denaturated meal, the denaturated meal is subjected to centrifugation through a centrifugal machine; supernatant obtained through centrifugation is treated with a membrane ultrafiltration technology, and a fructus cannabis concentrate protein solution is prepared; finally, the fructus cannabis concentrate protein solution finishing ultrafiltration treatment is subjected to spray drying, and the CBD-rich fructus cannabis concentrate protein powder with good quality can be obtained. The CBD-rich fructus cannabis concentrate protein powder has higher protein content, shallow color, high CBD content and excellent function characteristic. The method adopts a simple process, large-scale implementation is facilitated, the application range of the denaturated fructus cannabis meal is widened, and development and utilization of a high-value-added product of fructus cannabis are promoted.

Description

technical field [0001] The invention relates to a protein powder, in particular to a concentrated hemp protein powder rich in cannabidiol and a preparation method thereof; it belongs to the field of development technology and application technology of hemp, and is specifically prepared from high-temperature denatured hemp meal A cannabidiol (CBD) rich hemp protein concentrate powder with good functional properties. Background technique [0002] Hemp, also known as Chinese hemp and castor, is one of the traditional medicinal materials and health food raw materials in my country. The 2002 document of the Ministry of Health included hemp seed in the "list of items that are both medicine and food", which makes the development and utilization of hemp food legally guaranteed. Studies have shown that hemp seeds contain about 40-50% oil and 25-30% protein, so hemp meal is a good source of vegetable protein. [0003] Denatured hemp meal is a by-product produced in the process of pr...
