Product Introduction

1,3-Dioleic acid-2-palmitic acid triglyceride, commonly known as OPO, is a structured triglyceride, carefully designed to mimic the fat composition found in human milk. Its unique structure features palmitic acid at the sn-2 position of the glycerol backbone, with oleic acid at the sn-1 and sn-3 positions. This specific arrangement is key to its beneficial properties, particularly in infant nutrition, aiding in fat absorption and calcium uptake. OPO is produced through enzymatic interesterification, and it appears as a white to off-white powder or granules.

Production Process

The production of 1,3-Dioleic acid-2-palmitic acid triglyceride typically involves enzymatic interesterification. This process rearranges the fatty acids on the glycerol backbone of triglycerides using enzymes as catalysts. The reaction usually starts with a mixture of tripalmitin and oleic acid, which are then combined under specific conditions with a suitable enzyme. The enzyme facilitates the exchange of fatty acids, resulting in a triglyceride structure enriched with palmitic acid at the sn-2 position and oleic acid at the sn-1 and sn-3 positions. The resulting product is then refined, purified, and standardized to meet the required specifications for use in food and nutritional applications. The final steps often include deodorization, bleaching, and filtration to ensure the purity and stability of the OPO.

Functions and Effects

The primary function of 1,3-Dioleic acid-2-palmitic acid triglyceride is to improve fat absorption and calcium uptake, particularly in infants. In standard triglycerides, palmitic acid is often located at the sn-1 and sn-3 positions, which, upon digestion, leads to the formation of insoluble calcium soaps in the intestine, reducing both fat and calcium absorption. With palmitic acid primarily at the sn-2 position, as in OPO, it is less likely to form these insoluble soaps, thereby promoting better fat digestion and calcium absorption. This can lead to several benefits, including improved bone mineralization, softer stools, and reduced colic in infants. Additionally, enhanced fat absorption supports overall growth and development by making more energy available to the infant.

Application Scenarios

1,3-Dioleic acid-2-palmitic acid triglyceride is primarily used in infant formula to mimic the fat composition of human milk. It is also incorporated into other nutritional supplements and food products aimed at improving fat and calcium absorption, and it can be found in products designed for individuals, with specific dietary needs related to fat digestion. OPO is frequently used in clinical nutrition to support patients who have difficulty absorbing fats.

Packaging and Storage

1,3-Dioleic acid-2-palmitic acid triglyceride should be stored in a cool, dry, and well-ventilated place to maintain its stability and quality. Proper packaging is essential to prevent exposure to moisture, light, and air, which can degrade the product. Typically, it is packaged in airtight containers, such as sealed bags or drums, often with inert gas flushing to minimize oxidation. The recommended storage temperature is usually below 25°C, and the shelf life is generally 24 months from the date of manufacture, provided that the storage conditions are strictly followed.
