Preparation technology of peony seed oil

Abstract

The invention discloses a preparation technology of peony seed oil. The method comprises the steps that peony seeds are cleaned away and impurities are removed; drying is performed; husking is performed, and the husking rate is 98%; the peony seeds are stir-fired under the temperature of 115 DEG C for 25 min; squeezing is performed; oil is heated to 65 DEG C, water with the weight being 3.5% that of the oil is added, stirring is performed for 25 min, stirring is stopped when the temperature is 80 DEG C, and standing is performed for 3.5 h; the oil is rapidly heated to 55 DEG C, in the stirring process, alkali liquor with the weight being 8% that of the oil is added, when soapstock particles exist in the oil, the speed is adjusted to 25 turn / min, the temperature is increased to 70 DEG C, when the soapstock particles become larger, stirring is stopped, and standing is performed for 6 h for cooling; hot water is used for mixing middle layer oil, and filtering is performed three times; the oil is transferred to a bleaching tank, activated clay with the weight being 3% that of the oil is added, stirring is performed for 55 min under the temperature of 90 DEG C, and a vacuum pump is used for suction filtration; a deodorization pot is vacuumized, oil is sucked into the pot by means of vacuum, the pot is heated under the temperature of 200 DEG C, when the temperature is 110 DEG C, water vapor is introduced to the bottom of the pot, the water spraying time is 2.5 h, and the residual pressure is 0.08 MPa, when the water spraying time is 2.3 h, heating is stopped, and when the water spraying time is 2.5 h, water vapor spraying is ended, and the oil is cooled to 30 DEG C. The method can solve the problems that the peony seed oil extraction rate is low and the taste is poor.

Description

Technical field: [0001] The invention relates to the technical field of edible oil processing, in particular to a preparation process of peony seed oil. Background technique: [0002] Peony seed oil is a tree nut vegetable oil extracted from peony seeds. It is unique to China. It is unique because of its rich nutrition and health care function. It is called "the best oil in the world" by relevant experts. Treasures, but also China's unique health care edible oils. [0003] The unsaturated fatty acid content of peony seed oil is more than 90%, especially the polyunsaturated fatty acid-linolenic acid content is more than 40%, which is 140 times that of olive oil, and many other indicators are also higher than other oils, that is to say, Peony seed oil is the most suitable oil for human nutrition among the oils found so far, and its composition structure is very reasonable. Although the nutritive value of the peony seed oil is extremely high, and it also has the function of m...
