Mono-and diglycerides

产品介绍

Mono-and diglycerides 是由甘油三酸酯在胃肠腔中被胰脂肪酶分解而形成的。Mono-and diglycerides 是一种食品添加剂，用作非离子型乳化剂，主要存在于食用脂肪中。

生物活性

Mono-and diglycerides is formed by triglycerides being broken down by pancreatic lipase in the gastrointestinal lumen. Mono-and diglycerides is a food additive used as a nonionic emulsifier and mainly present in food fats.

体外研究

Squalene and Mono-and diglycerides on the frying stability of olive pomace oil is determined. Refined olive pomace oil is distilled using a falling film type short-path distillation unit at 230℃ under a pressure of 0.02 mbar to remove minor components. Distilled olive pomace oil is introduced with approximately 10,000 mg/kg of squalene and 2.5% of Mono-and diglycerides. Fryings are performed 8 times/day at 180 °C for 3 min. All criteria except smoke point and iodine value increased in all fractions during fryings. The lowest total polar compound is obtained in distilled olive pomace oil while polymerized triglycerides is the lowest in the Mono-and diglycerides added fraction.

体内研究

In the body, the triglycerides undergo digestion in the gastrointestinal lumen. Triglycerides are broken down mainly by pancreatic lipase with the formation of Mono-and diglycerides. Mono-and diglycerides are absorbed into the intestinal cells. In their passage through the intestinal mucosa Mono-and diglycerides are largely converted back into triglycerides. These pass into the body as a fine emulsion and give rise to the milky appearance of the chyle and the blood plasma. Under certain circumstances, these fat particles can be broken down by another fat-splitting enzyme in the blood-stream. When this occurs, the formation of Mono-and diglycerides can be demonstrated.
