Problems solved by technology

[0003] Pomegranate seed oil has various biological effects such as lowering blood lipids, preventing vascular sclerosis, lowering blood concentration and preventing thrombosis, and can also produce and maintain the normal structure and function of epithelial and nerve cells, as well as anti-oxidation, anti-aging, protection of vision, and promotion of children's health. Physiological effects such as growth and development, pomegranate seed oil is used in various groups of people, especially for middle-aged and elderly people. External use of pomegranate seed oil for skin care can not only absorb skin, nourish skin cells, textile rough and keratinized skin, but also is extremely lubricating and refreshing. Non-irritating, it is a good natural skin care product. Generally, the pomegranate seeds are thrown away directly after the pomegranate juice is squeezed, and only a small part is further processed, resulting in a great waste of resources. At present, most of them use subcritical low-temperature extraction technology. Carry out the extraction of pomegranate seed oil, complex operation, higher cost, therefore, need to improve a kind of efficient and high-quality extraction method of pomegranate seed oil

Embodiment 1

[0024] A high-efficiency and high-quality extraction method for pomegranate seed oil, comprising the following steps:

[0025] The first step, pomegranate seed pretreatment, crush the pomegranate seed, pass through a 60-mesh sieve, collect the pomegranate seed powder, add vitamin E to the pomegranate seed powder, stir and mix evenly, and dry at 65°C for 4 hours to obtain the pretreated pomegranate seed powder ;

[0026] The second step is to add the pretreated pomegranate seed powder to the round bottom flask, add ethyl acetate to the round bottom flask, put the round bottom flask into the microwave oven, and microwave the 400W power for 5 times, each time for 50s, and then suction filter , collect filtrate A, wash the filter residue three times with ethyl acetate, collect filtrate B, mix filtrate A and filtrate B, and evaporate to 1 / 3 of the original volume in a rotary evaporator at 78°C to obtain crude pomegranate seed oil;

[0027] The third step is to pass the crude pomeg...

Abstract

The invention discloses an efficient and high-quality pomegranate seed oil extraction method, which comprises the steps of pomegranate seed pretreatment, microwave treatment, D101 macroporous resin purification, antioxidant addition and the like, and is characterized in that pomegranate seeds are crushed and mixed with vitamin E before the pomegranate seeds are extracted, and the pomegranate seedsare extracted by utilizing the characteristics that the vitamin E is sensitive to oxygen and easy to oxidize .Pomegranate seeds are protected from being oxidized and decomposed in the crushing and ultrasonic extraction process, a microwave extraction method is used, the characteristics of rapid microwave heating and damage to biological cell structures are utilized, the extraction time is greatlyshortened, ethyl acetate serves as an organic solvent, the pomegranate seed oil extraction rate is excellent, and the method is suitable for industrial production. Finally, a compound antioxidant isadded into the extracted pomegranate seed oil, and safety and stability of the pomegranate seed oil in the storage and transportation process are guaranteed through the strong antioxidant capacity ofsesamol, rosmarinic acid and Lascorbyl palmitate.

Description

technical field [0001] The invention belongs to the technical field of oil processing, and in particular relates to an efficient and high-quality extraction method of pomegranate seed oil. Background technique [0002] Pomegranate seed oil is the only polyunsaturated conjugated fatty acid of plant origin, its main component is punicic acid, and its content can reach 70-80%. Therefore, the structure of punicic acid is closest to conjugated linoleic acid (CLA) and it is called "super conjugated linoleic acid". The human immune system can prevent animal atherosclerosis, reduce cancer, and help the body resist cancer, obesity, diabetes and heart disease. Pomegranate seed oil can be widely used in the field of medicine and health care to alleviate women's menopausal syndrome. [0003] Pomegranate seed oil has various biological effects such as lowering blood lipids, preventing vascular sclerosis, lowering blood concentration and preventing thrombosis, and can also produce and m...
