Peanut is an important edible agricultural product in China. It is rich in nutrients such as protein, fat and amino acid, and has a high therapeutic value. As a highly adaptable crop, peanuts are grown in many parts of the country.
Peanut can be used as a dish or as a food ingredient, and processed into other foods such as peanut butter, peanut butter, peanut milk, peanut biscuits, peanut cake, peanut bread. Peanut candy is a kind of convenient food, which is popular among consumers because of its good taste, healthy nutrition, convenient eating, easy to store and carry.
If the production environment is poor, the peanut candy is easily contaminated by microorganisms, and then moldy and deteriorated, resulting in shortened shelf life of peanut sugar, which will affect the health of consumers and the production and operation of food enterprises.
So, how can we prevent the peanut candy from becoming moldy and prolong the shelf life of peanut candy ?
Zhou Jiang, chief engineer of Shanghai Kangjiu Disinfection Technology Co., Ltd. , which specializes in the development of food quality assurance technology, believes that scientific design and production processes, avoiding cross-contamination, and application of advanced food safety guarantee technologies such as dynamic sterilization machines can effectively prevent microbial contamination of peanut sugar by molds and other microorganisms. Extend the shelf life of peanut sugar .
The nutritional value and therapeutic value of peanuts are high. Peanut is rich in nutrients and is a healthy and affordable product. Studies have shown that peanuts contain a large amount of phytosterols, which is very beneficial to human health, especially the β-sitosterol contained in the prevention of colorectal cancer, prostate cancer and cardiovascular disease. Further research by American scientists found that peanuts also contain "resveratrol", which has strong biological activity, not only can resist cancer, but also inhibit platelet aggregation and prevent myocardial infarction and cerebral infarction. It contains 8.48 mg of zinc per 100 g of peanuts, which can enhance immune function and delay aging. Therefore, peanuts are known as "longevity fruit."
The main therapeutic effects of peanuts are as follows:
1. Lower cholesterol. Peanuts are sweet and flat, can strengthen the spleen and stomach, moisten the lungs and remove phlegm, and benefit Qi and stop bleeding. It can be used for spleen deficiency, weight loss, lack of food, dry cough and less phlegm, postpartum milk deficiency and other symptoms. The fat in peanuts can break down the cholesterol in the liver into bile acids, promote excretion, and thus lower the cholesterol content in the blood, which can be used to prevent atherosclerosis.
2. Peanuts can warm the stomach. In order to alleviate the high-risk stomach pain after the frost, you can consciously eat some warm stomach foods, such as peanuts, pumpkins, sweet potatoes, carrots, cabbage, etc., to achieve the purpose of stomach and warm stomach.
3. Delay aging. High levels of protein and amino acids in peanuts can improve memory and delay aging. Vitamin E contained in peanuts can delay tissue aging and enhance liver detoxification.
4. Strong hematopoietic function. Peanut has the function of stopping bleeding and promoting platelets, and the effect of peanut red is 50 times stronger than that of peanut itself. It is better to eat peanuts and even red ones.
Ingredients for the production of peanut sugar include sugar, peanuts, white sugar, and salad oil.
The main points of operation of processing peanut candy are as follows -
1. Choose peanut kernels with full granules, normal appearance, no mildew, no odor, and wash off the surface with clean water.
2. Remove the washed peanut kernels from the water, place them on a clean bamboo or stainless steel plate with holes, and drain the water.
3. Put the peanut kernels that have been drained in a wok and fry them. Stir the aroma and stop heating. In the process of frying, peanuts should not be scorched. Peanut kernels can also be baked in the oven.
4. Pour the sugar and white sugar into the pot, first heat it with medium heat and stir constantly to prevent burnt. When the syrup is boiled, switch to a simmer and add salad oil and continue to cook. When there is a lot of foam on the surface of the syrup, use a pair of chopsticks to pick out the syrup and check it. When the syrup can be pulled into a silk, and when it is broken, it will be crisp when it is broken.
5. Put the fried peanut kernels in step 3 above into a high-quality syrup, and mix well.
6. Spread a high-temperature-resistant food-grade plastic film on the bottom and four walls of a rectangular stainless steel frame. Pour the mixed peanut candy material from the previous step into this large box and spread it with a bamboo knife. When hardened, cut into small pieces of peanut candy of the same size with a knife.
7. When the peanut candy is cold to hard and does not stick, put it in a plastic bag and seal it in time.
8. Test peanut sugar in accordance with relevant food safety standards. Products that have passed the inspection are stored as finished products and stored in the warehouse for sale.
The total number of colonies exceeding the standard and moldy deterioration is a quality problem that is easy to occur in cakes such as peanut candy.
According to Zhou Jianli, chief engineer of Shanghai Kangjiu Disinfection Technology Co., Ltd., an important reason for the excessive microbial and moldy deterioration of peanut sugar is the peanut sugar waiting for packaging and the air in the cooling workshop and packaging workshop during the cooling and packaging process. Contact, and the air contains a large number of microorganisms such as bacteria and molds. These microorganisms will adhere to the surface of the peanut candy and enter the packaging bag along with the peanut candy, resulting in the microbial content of the packaged peanut candy exceeding the standard. During the shelf life, the microbes in the bag use peanut candy as a nutrient source to grow and reproduce rapidly, and the Zui eventually causes the peanut candy to be mildewed and deteriorated.
The use of dynamic sterilization equipment can effectively improve the hygienic quality of the air in the cooling workshop and packaging workshop, prevent the contamination of peanut sugar by microorganisms, and thus prolong the shelf life of peanut sugar .
NICOLER sterilization technology refers to a sterilization method in which the human-machine can work in the same field. When the air is sterilized, the staff does not need to leave, and is harmless to human health, so it is called dynamic sterilization technology. The sterilization equipment developed with dynamic sterilization technology is called dynamic sterilization machine .
With the increase of economic income and the spread of popular science knowledge, consumers' demand for food is not only good flavor, but also sufficient quantity, and also requires good nutrition and health effects. Peanut not only has high nutritional value, but also has good health functions, such as resisting cancer, inhibiting platelet aggregation, preventing myocardial infarction and cerebral infarction, and delaying aging. Therefore, as a healthy food, peanuts are suitable for healthy consumption trends and are healthy foods for consumers.
In the process of peanut processing, the use of dynamic sterilizer and full-process food quality control measures can prevent microbial contamination of peanut sugar and other prolonged peanut sugar shelf life, contribute to the development of peanut food and meet the needs of healthy food consumption.
