Factors affecting acid price exceeding the standard

Since excessive acid prices can cause harm, what factors can lead to an increase in acid prices?

Raw materials and raw material storage

Generally speaking, the raw materials used for oil processing will directly affect the acid value of oil. For example, the acid value of oil obtained from mature oil seeds is smaller than that of immature or germinating moldy seeds. At the same time, if the raw materials are improperly stored or stored for too long, resulting in the decomposition of the oil in the raw materials, the acid value of the processed oil will inevitably increase.

Oil processing technology

During the production process, the operating process was not strictly controlled, the temperature was too high, and the time was too long, which accelerated the decomposition of the grease contained in it. During transesterification during oil processing and modification, the interaction between triglycerides in the oil causes transesterification or molecular rearrangement. Triglycerides are decomposed by heat or lipase during the oil production process to produce free fatty acids, thereby increasing the acid value of the oil.

Storage methods and conditions of oils and fats

During the storage of finished oil, due to different packaging materials and packaging forms, the moisture, temperature, light, lipase and other factors of the finished oil may be affected. The temperature and humidity of the storage environment will also greatly affect the acid price changes of oil. The longer the storage time, the more oil will be decomposed into free fatty acids, which will increase the acid value and reduce the storage stability.
