Do you know the principle behind making pork jerky with a light and crispy texture?
Traditional hot air drying and oven baking belong to the heat conduction heating from the outside to the inside, where the heat first contacts the surface of the meat jerky and then penetrates the inside, resulting in a slower drying speed.
Microwave processing is the core process for mass production of crispy pork jerky, which reshapes the internal fiber structure of the jerky through unique internal heat generation and micro expansion effects, stabilizing the production of lightweight, fluffy, and crispy high-quality products.
Microwave drying adopts the principle of penetrating integral heating to change the dehydration and shaping logic of meat jerky. Microwave energy can directly penetrate the entire piece of pork jerky, activate high-frequency vibration of water molecules inside the meat, generate heat through friction, and achieve synchronous heating and dehydration of the surface, middle, and inner layers of the jerky.
During the rapid drying process, the moisture inside the meat jerky evaporates instantly, creating a uniform and small air pressure between the gaps in the meat jerky material. The mild internal air pressure will slightly expand the dense flesh fibers, forming a large number of uniform and fine microporous structures, producing a slight and natural puffing effect. This loose and porous internal structure is the core key to the crispy texture of pork jerky.
After processing, the pork jerky naturally cools and solidifies, with a stable internal microporous structure that is lightweight, fluffy, and has a loose texture. It can be easily crushed with a light bite, and its crispness is even and transparent.
At the same time, the characteristics of microwave low-temperature short-term processing will not damage the meat quality and seasoning flavor of the meat jerky, which can well preserve the meat aroma and seasoning layer, and balance the crispy taste, flavor, and overall quality. It is suitable for standardized batch production of crispy ready to eat pork jerky.
