Key points of peanut oil production
Raw material selection: The oil used to produce strong flavored peanut oil requires mature and plump seeds that have not undergone aging, and must not have moldy, damaged, or immature seeds. These damaged and moldy oilseeds can easily affect the acidity and flavor of peanut oil, and may even be contaminated with aflatoxins.
Pre treatment process: This is an important process that affects the oil yield and flavor of edible oil, including cleaning, crushing, steaming, and frying of peanuts. These processes can adjust the moisture and temperature of peanut kernels, causing the oil to absorb water and expand, splitting the cell wall, thereby opening up oil channels, reducing oil viscosity, and increasing oil yield.
Baking and frying temperature: Baking and frying are key processes for producing strong flavored peanut oil, and temperature control is crucial. The temperature is not enough, and the aroma of peanut oil is weak; If the temperature is too high, the oil will become burnt. Therefore, it is necessary to configure an automatic temperature controlled frying pan and set different temperatures according to different oil processing techniques to achieve high-temperature short frying and prevent oil gelatinization.
Refining process: The processing of strong flavored peanut oil requires specific refining processes, such as low-temperature crystallization, anhydrous dephosphorization, etc., to remove impurities such as wax and phospholipids from the crude oil and obtain a fragrant peanut oil.
Key points of cottonseed oil production
Raw material source: The main raw material of cottonseed oil is cottonseed, and the yield and quality of cottonseed directly affect the production of cottonseed oil. Therefore, it is necessary to pay attention to the planting area, yield, and collection, storage, and transportation of cotton seeds.
Pressing and refining: The production of cottonseed oil requires two main processes: pressing and refining. The pressing process uses mechanical pressure to squeeze out the oil from cottonseeds, while the refining process removes impurities and harmful substances from the oil through physical and chemical methods, improving the quality and safety of the oil.
Quality control: The quality control of cottonseed oil is an important link in the production process. Strict control of raw material quality, pressing conditions, refining processes, and other parameters is required to ensure that the final product meets national standards and consumer demands.
Market demand: Cottonseed oil has the characteristics of light taste and good oxidation stability, making it an ideal raw material for producing salad oil, margarine, and shortening. At the same time, in the food industry, due to its high smoke point and ignition point, the shape and color of the fried food are good, and it is often used as frying oil. Therefore, it is necessary to closely monitor changes in market demand and adjust production strategies and product structures in a timely manner.
In summary, the production of peanut oil and cottonseed oil involves multiple aspects such as raw material selection, pretreatment process, roasting temperature (unique to peanut oil), refining process, quality control, and market demand. The effective control and management of these key links are of great significance for improving product quality, reducing costs, and enhancing market competitiveness.
