Nutritious, healthy, convenient and fast eight-treasure porridge has become a must-have breakfast for many people in the morning. It has won the love of many people with its sweet and soft taste and rich and diverse ingredients. The main ingredients are red beans, mung beans, glutinous rice, wheat, peanuts, lotus seeds, longan, etc., which are not only rich in dietary fiber, protein, carbohydrates, but also contain a variety of vitamins and minerals. Whether it is carried or eaten, eight-treasure porridge can meet everyone's needs to replenish energy at any time. There are various forms of packaging for eight-treasure porridge, including cans, cups, bowls, bags, etc., among which iron cans are the most common. The shelf life of eight-treasure porridge packaged in tinplate cans can generally reach 1-2 years, which makes people wonder: why can canned eight-treasure porridge without preservatives be left for so long without spoiling?This is due to the unique production process of Babao porridge, especially the two links of canning and sterilization. 
First of all, Babao porridge has gone through raw material processing, pre-cooking, canning, sterilization and other processes in the manufacturing process. Among them, canning and sterilization are the two most critical links. After a raw meal filling, the maturation and sterilization process is completed at one time at high temperature in the sterilization pot. As long as the can is completely sealed and not deformed at the time of consumption, there is almost no possibility of spoilage during the shelf life. 
So, which sterilization process is more suitable for the sterilization of eight-treasure porridge?Due to the viscous texture and rich ingredients of eight-treasure porridge, it is easy to stratify after heating at high temperatures. In order to prevent this from happening, we recommend that Babao porridge manufacturers use a rotary sterilization kettle. The rotary sterilization kettle is suitable for high-viscosity products and large-size packaging, in which the product is constantly rotated at a uniform speed to make its heat transfer more uniform, thereby shortening the sterilization time and achieving the effect of high-temperature short-term sterilization. This not only saves the energy consumption of sterilization, but also avoids the occurrence of the phenomenon of delamination of eight-treasure porridge and improves the yield of the product. Next, according to the specific packaging form of the product, we will recommend customers to choose to use the water immersion sterilization process or spray sterilization process. Water immersion sterilization is suitable for large-capacity, viscous product sterilization, and the process water can be recycled, which is more energy-saving. During sterilization, all the food in the pot is soaked in hot water, and the temperature control system can be flexibly and automatically controlled according to the characteristics of different packaging. The pressure control system automatically adjusts the pressure with the standard mode, and corrects the back pressure according to different situations, so as to prevent the deformation and damage of the container and improve the yield rate. The water circulation is facilitated by a pressure system and a pump, which provides a relatively uniform heat distribution and fast heat transfer. 
The spray sterilization method is divided into top spray type, side spray type and full spray type. In this way, nozzles and spray pipes are used to spray hot water into the surface of the food in a mist wavy shape, and the temperature is transmitted evenly without dead ends. The water is heated and cooled by an exclusive patented heat exchanger, which heats up and cools quickly to sterilize the product. In short, the reason why Babao porridge can maintain its quality and taste for a long time depends not only on reasonable recipes and advanced production technology, but also thanks to a rigorous sterilization process. It is the strict control of this series of links that enables the eight-treasure porridge to maintain its original quality and taste during the shelf life. And for consumers, no matter which packaging form of eight-treasure porridge is used, as long as it is stored and used correctly according to the instructions, they can enjoy a delicious and nutritious breakfast.
