Introduction to Peanut butter

China is the world's largest peanut production country, its total output, single output and export volume are ranked first in the world. Currently, peanut butter accounts for 37 percent of China's edible peanut consumption.
Peanut butter is not only rich in vegetable protein, but also rich in vitamins, niacin, vitamin E and minerals, etc., rich in nutrition and unique flavor. Peanut butter is widely used in flour products, hot pot dip and other fields, but peanut butter has a high fat content, which is not suitable for high blood pressure, diabetes and other patients to eat, it is also easy to produce oil in storage, easy oxidation, rackness, and the non-fat part of peanut butter in the storage process naturally settles to form a hard solid substance. Thus, the flavor quality of peanut butter is reduced and the storage period is shortened. The research of new peanut butter aims at the defects of flavor, nutrition and stability. At present, a series of new peanut butter with low fat, high protein, unique flavor, high nutrition and good stability has been developed. 
In China, peanut butter is widely used as a condiment for pasta, steamed bread, hot pot, stir-fry, etc., and is also used as a filling for sweet cakes, steamed buns, bread, etc. Peanut butter has been exported from China since 1988. The main product of peanut butter is full-fat peanut butter, but there are few researches on low-fat or nonfat peanut butter and nutrient-flavored peanut butter.
