Embodiment 1
[0037] Embodiment 1,Low trans acid modified oil composition of the present invention
[0038] A low-trans-acid modified oil composition, which is obtained by transesterification of raw material oil. The raw material oil is composed of at least two components as follows, and the sum of the percentages of each component is 100%:
[0039] 0-15% of hard palm oil, 0-15% of soft palm oil, 65-75% of butter, 20-30% of soybean oil, 0-15% of coconut oil, the trans fatty acid content of the oil composition Less than 1.0%.
[0040] The preparation process of the present embodiment 1 oil composition is as follows:
[0041] 1) According to the formula, add the raw material oil to the esterification reaction kettle in proportion, and at the same time vacuumize the inside of the kettle so that the pressure intensity is 0-3500Pa;
[0042] 2) Use a heat exchanger to increase the temperature of the oil in the kettle to 150°C, control the temperature at 140-160°C, stir, and then add a stro...

Abstract
The invention discloses a low-trans acid modified oil and fat composition and a preparation method thereof, and belongs to the technical field of oil and fat deep processing. The low-trans acid modified grease composition is obtained through raw material oil transesterification. The raw material oil comprises at least two components of 0 to 50% of soybean oil, 0 to 95% of stearic palm oil, 0 to 100% of palmitin palm oil, 0 to 80% of beef tallow and 0 to 50% of coconut oil, wherein the sum percentage of the components is 100%. After the transesterification is conducted on the raw material oil, the position of fatty acid at the triglyceride is rearranged, the low-trans acid modified oil and fat composition with the ideal solid fat content characteristics at the relative temperature is obtained, the melting point of the modified oil and fat composition is close to human body temperature, ductility, whipping property and durability after whipping are optimized, the trans-fatty acid content of the composition is reduced to be smaller than 1.0%, healthy oil and fat raw materials with the low trans-fatty acid content is provided for margarine, and development of oil and fat industry is facilitated.
Description
technical field [0001] The invention belongs to the technical field of oil deep processing, and in particular relates to a low-trans-acid oil composition and a preparation method thereof. Background technique [0002] Most of the formulas of traditional margarine products use partially hydrogenated oil as raw material, and partially hydrogenated oil will contain higher trans fatty acid (TFA, trans fatty Acid), resulting in higher content of trans fatty acid in the final product (Content in 5-40%). In recent years, there has been increasing attention to trans fatty acids at home and abroad, and the understanding of trans fatty acids has become more and more in-depth. Medical research in Europe and the United States has clearly shown that long-term intake of large amounts of trans fatty acids, The harmful low-density lipoprotein cholesterol in the blood will increase, which is the main cause of obesity and ischemic heart disease, and brings great harm to people's health.
