Principle and roles of high temperature steam sterilization in palm oil production process

Sterilization is a key step in palm oil production process. Its main purpose is to sterilize palm fruits through high temperature steam to prevent microbial contamination and enzyme decomposition. This process not only ensures the quality of palm oil, but also prevents the increase in the acid price of palm fruits, thereby improving the stability and economic value of the oil. This article delves into the principle and roles of high temperature steam sterilization in palm oil production process.

1. Principle of High Temperature Steam Sterilization in Palm Oil Production Process

Use high temperature steam to steam palm fruits to destroy the microbial cell structure and inhibit its growth. Cook the fruit skewers softly by high temperature and sterilize at 145°C for 60-90 minutes. This high temperature environment can effectively kill most microorganisms, while making the palm fruit soft, making it easier to thresh and press palm fruit later.

2. Roles of High Temperature Steam Sterilization in Palm Oil Production Process

(1) Softens Palm Fruit to Improve Palm Oil Production Efficiency

The main purpose of high temperature steam sterilization is to soften the palm fruit. This not only makes it easier to separate the palm fruit from the bunch, but also increases the moisture content of the palm fruit, which facilitates the subsequent palm oil extraction and separation of the palm kernel and the shell. The heat of the steam penetrates into the palm fruit, destroying the cell structure and liquefying the oil, which facilitates subsequent extraction. Without adequate sterilization, the oil will be difficult to separate, resulting in reduced yield and increased palm oil production time.

(2) Inhibits the Decomposition of Lipolytic Enzymes

Freshly picked palm fruits contain lipolytic enzymes, which can break down triglycerides (the main component of oils) into free fatty acids and glycerol. This process, called hydrolysis, increases the acidity of the oil, which significantly reduces the quality of the extracted palm oil. High temperature steam sterilization can effectively inactivate these enzymes, prevent hydrolysis, avoid the increase in the content of free fatty acids, and ensure the quality of crude palm oil.

(3) Purifys Microorganisms

High temperature steam sterilization also serves as a powerful microbial control mechanism. By subjecting the fruit bunches to temperatures typically ranging between 145°C, it eliminates or significantly reduces the microbial load present on the fruit surface and within the palm fruits. This process is vital in preventing spoilage and extending the shelf life of both the crude palm oil and subsequent refined products.
