Embodiment 1

[0038] A preparation method of hemp seed oil rich in cannabidiol (CBD), the steps are as follows:

[0039] Raw material pretreatment: wash hemp leaves and hemp seeds with water and dry them with vacuum drying equipment, wherein the hemp seeds are extruded and shelled to obtain hemp seeds, and then the hemp leaves and hemp seeds (water content 3%) crushed to a particle size of 1-5mm.

[0040]The pulverized hemp leaves and hemp seeds (collectively referred to as hemp material powder, wherein the hemp leaves account for 35% of the hemp seed mass) are measured in volume and packed into a closed extraction tank, and press the hemp material powder Volume: Solvent volume = 1:1 Inject the extraction solvent, mix and perform subcritical extraction; the extraction solvent is butane and ethanol with a volume ratio of 1:0.5, the extraction pressure is 0.5MPa, the extraction temperature is 40°C, and the extraction time is 2 hours , the number of extractions is 4 times;

Abstract

The invention relates to a cannabidiol-rich hemp seed oil and a preparation method thereof. The method comprises the following steps: 1, decorticating: decorticating dried hemp seeds to obtain hemp seed kernels and shells; 2, crushing: crushing dried hemp leaves and hemp seed kernels to obtain a hemp material powder; 3, extracting: carrying out subcritical extraction on the hemp material powder toobtain an extract; 4, desolventizing: evaporating the extract under a reduced pressure to remove an extracting solvent to obtain an extract concentrate; and 5, centrifuging: centrifuging the extractconcentrate to obtain a supernatant which is the cannabidiol-rich hemp seed oil. The hemp leaves and hemp seeds are compounded to serve as extraction raw materials, and undergo a subcritical extraction technology to obtain the cannabidiol-rich hemp seed oil (the content of cannabidiol is 0.20-0.28%), and the method has a high oil yield of 80-95% and a high recovery rate of 25-28%.

Description

technical field [0001] The invention relates to the technical field of hemp development, in particular to hemp seed oil rich in cannabidiol and a preparation method thereof. Background technique [0002] Hemp, also known as hemp and industrial hemp, is a short-sun, annual herb with palmately divided leaves and mostly dioecious plants. It 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. This also makes condition and support provided to the development of hemp plant mosaic. In recent years, with the deepening of people's understanding of hemp and the in-depth research on the strong physiological functions of its processed products, countries have generally reopened the restrictions on the development of hemp and its products. What follows is...
