Problems solved by technology

At present, Wuhan Institute of Technology and Xingguo Hongtianxia Camellia Oil Co., Ltd. propose to use Maillard reaction to produce Luzhou-flavored camellia oil under high temperature conditions. It is obtained by crushing and enzymatically hydrolyzing oil, and then adding pressed and refined camellia oil at a high temperature of 120°C for 60 minutes to obtain product, but due to the high temperature treatment, the oxidation of lipids and the destruction of heat-sensitive physiologically active substances in camellia oil, this technology can obtain strong-flavored camellia oil at 120 ° C for 60 minutes, but the product quality and nutritional efficacy are reduced, the product The grade is lowered

Abstract

The invention discloses an aroma camellia oil which is prepared by adopting the following steps: (1), preparing foots slurry; (2), performing enzymolysis and Maillard reaction; (3), obtaining fragrant digestion grease; and (4), dewatering. According to the fragrant camellia oil, camellia oil foots is adopted as a raw material for preparation, and aroma substances are mainly from a protein denaturation aroma and a aroma formed by reducing sugar in camellia seeds and amino acid in a low-temperature enzymatic process through the Maillard reaction. According to the fragrant camellia oil, the problems of influence of high temperature on quality of the camellia oil in a conventional cooking aroma enhancing procedure, inactivation of active substances in nutritional ingredients in the camellia oil due to the high-temperature long-term Maillard aroma enhancement reaction of and aroma reduction of the camellia seed oil are avoided, and thus the camellia oil which is not damaged in nutrient substances and is thick in aroma is obtained. The camellia oil has the advantages of recycling waste materials, and being simple in process, low in operation cost and stable in product quality. The aroma camellia oil prepared by using the preparation method disclosed by the invention is capable of generating higher economic benefit.

Description

technical field [0001] The invention relates to the technical field of edible oil, in particular to a scented camellia oil and a preparation method thereof. Background technique [0002] Eating fragrant vegetable oil is a characteristic of Chinese diet. Traditional fragrant oil is widely used in cooking and cold salad, etc., and is deeply loved by consumers. At present, the processing of scented oils adopts the traditional production process. Usually, the whole grain raw materials are roasted and pressed at high temperature or the raw materials are pressed first and then steamed and fried at high temperature. The main purpose is to heat denature the protein to improve the yield At the same time, the aroma produced after protein denaturation is integrated into the oil. Because the acid value and peroxide value of the oil are easy to increase under high temperature conditions, and the heat-sensitive active substances in the oil are destroyed at the same time, the oil produced ...
