Processing of Peanut Oil

Some clients reported that the peanut oil they produced do not have good smell or fragrance was too weak. Actually, there are many factors that make peanut oil smell unscented, mainly in the following aspects:

  • Quality of Peanut

The quality of peanut raw materials can influent the taste of extracted oil directly. Good peanut oil requires good groundnut resources. There is no doubt that the peanut used for manufacturing superfine fragrant peanut oil should be fresh and full seed, so as to make the high quality peanut oil with strong fragrant.

  • Proportion of Raw Peanut and Cooked Peanut

The proportion of raw peanut and cooked peanut also matters. Generally, it should be controlled to 3:1. If the proportion of cooked peanut is too small, the smell of extracted peanut oil will be lighter. If the proportion is too big, the oil yield will be lower. The crude oil will be cloudy and it will increase the difficulty of subsequent process.

  • Cooking Temperature

The pretreatment process before oil extraction in peanut oil expeller is definitely a skilled task. The control of moisture content and temperature are both key factor that can greatly affect the oil yield and oil flavor. Cooking is the key step in the production of strong fragrant peanut oil. The oil fragrance has a direct relationship with the seeds cooking process. If the temperature is too low, the fragrance is lighter. If the temperature is too high, the peanut will be burned easily. Generally speaking, the cooking temperature should be controlled 180℃ ~ 200℃. Besides, to prevent gelatinization and spontaneous combustion, the seeds should be cooled immediately after cooking.
