Prospects for development

More than 30,000 tons of food emulsifiers have been approved for use in China, and the world’s consumption of food emulsifiers has exceeded 400,000 tons. The varieties and dosage of food emulsifier products in China are far less than those in foreign countries. Developing new varieties of emulsifiers with various functions and enriching the intrinsic functions of Chinese food emulsifiers should become the idea of the industry in developing new products.

Span:

Sorbitan esters (also known as sorbitan fatty acid esters) are nonionic surfactants that can be mixed with polysorbates in varying proportions to produce lotions or creams with a variety of textures and consistency. They are suitable as water-in-oil (W/O) emulsifiers that are soluble in hot oil and many organic solvents but insoluble in water. In addition, they are non-toxic, tasteless, easily biodegradable, and can be used in food, medicine, cosmetics, textile industry, etc.

The colors of the Span are amber viscous liquid, slightly yellow waxy solid, amber viscous oily substance and yellow oily liquid. Due to different states, the packaging of Span is also different. Span S-20, Span S -80, Span S-85 is packed in 50Kg plastic drum; Span S-40, Span S-60 are packed in 20Kg woven bag.

Spans in different states are named differently. Jihua.com Span series includes Span 20 Span 40 Span 60 Span 80 and Span 85. The numbers behind Span represent different fatty acids, such as Span-20. (SP-20) represents monolaurate; Span-40 (SP-40) represents monopalmitic acid (palmitic acid) ester; Span-60 (SP-60) is monostearate; Span- 80 (SP-80) is monooleate.

Span has different specifications and can be divided into industrial grade, food grade and pharmaceutical grade. The main difference between these three classification systems is that the former focuses on content, while the latter focuses on “quality” (whether it is harmful to the human body or the environment). Generally speaking, the price of industrial grade is the cheapest, followed by food grade, and pharmaceutical grade is the most expensive. It can be said that pharmaceutical grade can be used instead of food grade, and food grade can be used instead of industrial grade.
