Complete set of diacylglycerol production solutions

Natural Source and Content

Diglyceride is a natural trace component of oil, accounting for only 0.8%-9.5% in ordinary edible oil (such as 1% soybean oil and 9.5% cottonseed oil). Due to its health potential, commercially available diester oil is purified through technology to increase the DAG content to more than 40%, and the main raw materials are soybean oil, rapeseed oil, etc.

Diacylglycerol edible oil, represents a new generation of functional edible oil that preserves dietary habits, meets the texture requirements of daily life, and enables healthy consumption.

Technology for Diacylglycerol Oil Preparation

Huatai Group adopts molecular distillation technology for the production of diacylglycerol oil. The production process uses oils and fats as raw materials, with lipase preparations, water, glycerol, etc., as main auxiliary materials. Through lipase catalysis, it is manufactured via processes such as distillation separation, decolorization, and deodorization. The key technologies and industrialization of enzymatic diacylglycerol production have become important means to improve product quality and increase output.

Diacylglycerol oil preparation technology

Core Production Technology: Enzymatic Catalysis

Enzymatic synthesis: Mainstream processes include glycerol hydrolysis (oil + glycerol → DAG), ester exchange (oil + monoglyceride → DAG) and direct esterification (fatty acid + glycerol → DAG). Among them, the direct esterification method has the highest efficiency and can obtain 70% pure DAG within 6 hours.

Core production technology: enzymatic catalysis

Diacylcerol (DAG)

Broken down into 1-monoglyceride + free fatty acids → Cannot be reorganized into TAG, reducing fat synthesis → Directly enter the liver for β-oxidation to provide energy → converted into energy rather than fat.

The free fatty acids (FFA) hydrolyzed from diacylglycerol are not as much as those from triacylglycerol, so the materials for resynthesizing triacylglycerol in the epithelial cells of the small intestine are relatively scarce, and the triacylglycerol chylomicrons finally formed are far less than when triacylglycerol is directly ingested.

Differences Between Traditional Edible Oils and Diacylglycerol Edible Oils

Composition of conventional edible oils

  • Triacylglycerols (TAG) account for 98%
  • Diacylglycerols (DAG) constitute 2%
  • Prone to causing fat accumulation
  • One of the root causes of numerous chronic diseases
Differences between traditional edible oil and diacylglycerol edible oil

Composition of diacylglycerol (DAG)-enriched edible oils

  • DAG content ≥ 40%~80% in specialized oils
  • Not prone to accumulation
  • Healthier
  • A natural oil component without burden

The metabolism of diacylglycerol is very different from that of triacylglycerol. The absorption of diacylglycerol is different from that of triacylglycerol. Its polarity is between monoacylglycerol and triacylglycerol, and it is easier to emulsify, which is beneficial to digestion and reduces the burden of fat digestion on the intestine.
