The puffed snacks we eat everyday, such as fried crisps, crisps, Fried Dough Twists, are golden, crisp and fragrant when they first come out of the pot. But if left unattended for a period of time, it will become soft and fluffy, and the taste will deteriorate. What's going on?
In fact, fried snacks have a loose and porous structure, and after high-temperature frying, they have many internal pores and low moisture content. This is the source of their crispy texture, but it also makes them highly susceptible to absorbing moisture and microorganisms in the air. Water vapor seeps into the pores, softening the starch structure and causing the snacks to lose their crispness.
The microwave drying sterilization process precisely solves the pain point of poor taste of fried snacks and has become an important process in snack processing.
Unlike traditional ovens that bake from the outside in, microwaves have a penetrating and uniform effect, which can activate residual moisture inside snacks, allowing deep moisture to quickly vaporize and be discharged, and controlling the moisture content of the finished product. Microwave processed fried snacks have dry and transparent pores, bidding farewell to the problem of softness and hair loss, long-lasting crispness, and uniform taste.
At the same time, microwaves also have physical sterilization effects, relying on thermal and biological effects to kill bacteria and mold attached during snack processing and cooling, reducing the risk of microbial growth. The entire process is very fast and will not damage the original color, aroma, and quality integrity of the fried snacks.
In large-scale production, the advantages of this process are very obvious. Without relying on preservatives, relying solely on physical drying and sterilization can stabilize snack quality and extend shelf life. It not only solves the industry problem of fried snacks being prone to moisture and spoilage, but also meets consumers' demand for clean ingredients and healthy snacks.
