Problems solved by technology

Among them, low-temperature pressing refers to processing at an environment below 60°C, and the nutrients are most completely preserved. However, since the oil yield of low-temperature pressing is only half of that of hot pressing, the price of most low-temperature pressing oils is relatively high. Pressed sesame oil is favored by people who pay attention to health and quality of life

Abstract

The invention provides a low-temperature squeezing technology of sesame oil, and relates to the technical field of production of edible oil. The technology comprises the following steps: (1) removingimpurities through a screening machine; and shucking to obtain sesame kernels; (2) adding water; stirring and heating to reach temperature of 30 DEG C; soaking for 20-40min; moving out the sesame kernels; draining water; refrigerating for 5-8h under the temperature of 0 DEG C; and performing vacuum microwave radiation; (3) feeding sesame into a spiral squeezing machine for squeezing; and pumping the sesame oil into a plate and frame filtering machine for filtering; (4) adding the filtered semi-finished sesame oil into an oil refining pot; stirring and heating to reach the temperature of 55-60DEG C; stopping heating; adding edible salt water with the same temperature as the oil to a pot; continuously stirring for 30-50min; and filtering to obtain hydrated oil; and (5) adding the hydrated oil to a reaction kettle; then adding activated clay and activated carbon; stirring and heating to reach the temperature of 50-60 DEG C; stirring for 60min; filtering; and then adding to a vacuum drying tank for drying for 40-50min to obtain the sesame oil product. The sesame oil product remains all nutritional components; and the oil yield is greatly increased by being compared with a traditionallow-temperature squeezing technology.

Description

technical field [0001] The invention relates to the technical field of edible oil production, in particular to a low-temperature pressing process of sesame oil. Background technique [0002] Sesame oil is a relatively common edible oil. When sesame oil is put in the dish, it will be more delicious and have a special aroma. Regular consumption of sesame oil has a lot of benefits for health, such as delaying aging, laxative, protecting blood vessels, etc., because sesame oil is rich in vitamin E, which is often called the "anti-aging vitamin". Because vitamin E can improve blood circulation in the human body, promote metabolism, thereby preventing the human body from accelerating aging. [0003] At present, the production technology of sesame oil mainly includes pressing method and leaching method. Among them, low-temperature pressing refers to processing at an environment below 60°C, and the nutrients are most completely preserved. However, since the oil yield of low-temper...
