Abstract

The invention discloses a preparation method of palm oil microemulsion. The method comprises the steps that (1) palm oil, Span 80 and ethyl alcohol are evenly mixed; (2) water is dropwise added, stirring continues, and the uniform and transparent palm oil microemulsion is obtained. The water-in-oil (W / O) microemulsion prepared by applying the method is transparent in appearance. The prepared palmoil microemulsion belongs to the category of nanomaterials and has the advantages of being free of toxicity or harm, biodegradable, good in biocompatibility and the like. The melting point of the palmoil microemulsion is increased, and the palm oil microemulsion has good shearing resistance and is less influenced by change of the temperature and shearing force. The used palm oil is low in price,good in processing performance and large in modification potential, the used palm oil of 24 DEG C, 33 DEG C and 43 DEG C is a food-grade oil application raw material, and the toxic effect cannot be caused. A surfactant and an auxiliary surfactant are simple and easy to obtain and are applied to the field of food pharmacy. The method does not need high-temperature or high-pressure treatment and issimple and easy to implement, the technology efficiency is high, the energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a palm oil microemulsion and a preparation method thereof, belonging to the field of production, preparation and application of the microemulsion. Background technique [0002] Oil palm is the most efficient oil-producing plant in the world. It has the reputation of "the king of oil in the world". It is mainly distributed in Malaysia and Indonesia in Asia, west and central Africa, northern South America and Central America. Palm oil refers to a triglyceride-rich oil that is pressed from the pulp of the palm on the oil palm tree. Saturated fatty acids and unsaturated fatty acids in palm oil each account for 50%, which has good oxidation stability and is an excellent industrial oil. As the edible vegetable oil with the most price advantage in the world, palm oil is cheaper than other bulk oils such as soybean oil and rapeseed oil, and has strong competitiveness in the world industrial processing market. Due to its low price, go...
