Abstract:
In order to better meet the requirements of fatty acid balance for adults and meet the demands of consumers for nutritional and healthy oils, 11 kinds of common vegetable oils and fractionated butter were used as the raw materials. On the premise of meeting the requirements of fatty acid balance and nutrient content, the price is taken as the index, and the MATLAB software was used for modeling and programming to obtain the formula of nutritionally balanced animal and vegetable blend oil. The blending process was optimized by the single factor and orthogonal experimental designs, and the shelf life was predicted. The results showed that the proportion of nutritionally balanced animal-plant blend oil was as follows: fractionated butter 8.00%, corn oil 16.40%, flaxseed oil 72.20%, sesame oil 3.40%; the unit price was 0.28 yuan per 100 ml, The actual measurements revealed the composition as follows: saturated fatty acids, 12.78%; ω-6/ω-3 polyunsaturated fatty acids (PUFA) ratio, 5.99 (which was between 4 and 6:1); the mass ratio of monounsaturated fatty acids (MUFA) to PUFA, 0.96 (which basically meets the required MUFA-to-PUFA ratio of 1:1). The fatty acid ratio of the blend oil was consistent with the expected value. The optimum blending process was as follows: stirring time, 30 min; TBHQ addition, 15 mg; stirring temperature, 20 ℃. The nutritionally balanced animal and plant blend oil had a shelf life of 18 months. The results of this study lay a theoretical foundation for the development of nutritionally balanced and healthy blend oils, and provide a new path for edible oil enterprises to develop new products.
