Peanut butter is a favorite food for many people, and the peanut butter machine plays an important role in the process of making peanut butter. Before grinding peanut butter, peanuts are usually peeled. This process seems simple, but it has important significance and function.

Next, we will discuss why it is necessary to peel peanuts before grinding peanut butter.

1, Improve the taste and quality of peanut butter.
Peanut skin is rough, with a certain degree of fiber. If you grind directly without peeled peanuts, it will not only affect the fineness of peanut butter, but also make the taste rough and even slightly bitter. After peeling, the peanut particles are purer, and the ground peanut butter is smoother and more delicate, and the taste is better. In addition, removing the skin can also prevent impurities or peculiar smell in the skin from interfering with the flavor of peanut butter, thus improving the overall quality.

2, Improve the color of peanut butter.
Peanut skin is usually reddish brown or deep red, while peanut kernel itself is milky white or light yellow. If you grind the peanut butter directly without peeling, the color of the skin will be mixed into peanut butter, which will make the finished product darker and may even look unattractive. After peeling, the peanut butter produced is brighter and more uniform in color, looks more attractive, and is more in line with consumers’ expectations of food appearance.

3, Reduce impurities in the processing process.
Peanut peels are easy to produce chips during processing, which may affect the operation efficiency of the machine and even block the equipment. In addition, the fiber components in the skin may form small particles that are not easy to decompose when grinding, which affects the uniformity of the finished product. By peeling, these impurities can be effectively reduced, making the whole processing process smoother and ensuring the purity of the product.

4, Improve the nutrient absorption rate.
Peanut kernel is rich in nutrients such as protein, unsaturated fatty acids and vitamin E, which are more easily absorbed by human body. Peeling can make these core nutrients more concentrated in peanut butter, thus improving its nutritional value.

5, Extend the storage time.
Peanut skin may contain a certain amount of lipid oxides or microbial residues. If these substances are not removed, it may accelerate the oxidative deterioration of peanut butter, thus shortening its shelf life. Peeling can effectively reduce these potential negative factors, prolong the storage time of products and improve food safety.

6, Meet market demand.
From the consumer’s point of view, most people prefer to choose peanut butter with delicate taste, uniform color and excellent quality. And peeling treatment is the key step to realize these characteristics. Therefore, peeling peanuts is not only a necessary technological process, but also an important means to meet market demand and enhance product competitiveness.

To sum up, although some people choose not to peel when grinding peanut butter at home, most people and factories peel peanuts in advance when processing peanut butter. This seemingly simple step plays an important role in ensuring the quality of the final product and the satisfaction of consumers.
