Background

Mutton is one of widely edible meats, is one of livestock meats which are eaten in every country internationally, is rich in nutrition, tender in meat quality and easy to digest, can resist wind cold and tonify bodies, is most suitable for being eaten in winter, is called as a winter tonic and is deeply popular with people.

Air-dried meat is a main traditional meat product in China and is famous for its color, fragrance and taste. In the Xinjiang pastoral area of China, a habit of pickling mutton chops and then airing the pickled mutton chops to be mature to form air-dried meat is provided in folk.

The tomato-rich dietary fiber air-dried mutton chop is a product prepared from fresh mutton chops through shaping, injecting dietary fiber, pickling liquid, inoculation, fermentation and air drying treatment, for example, the air-dried mutton chop has fresh taste and unique flavor and is deeply favored by people, but on the other hand, a minority likes meat, and rarely intakes vegetables, so that gastrointestinal diseases are frequent, and the dietary fiber is added into the mutton product, so that the nutritive value can be improved, and the intake of the dietary fiber can be increased, thereby reducing the illness probability of the gastrointestinal diseases, simultaneously utilizing the tomato byproducts, and prolonging the tomato industry chain.

Due to the fact that the tomato-rich dietary fiber air-dried mutton chops are difficult to manufacture, long in manufacturing period and difficult to control in quality, related products are not seen in the market at present.

Mutton is used as excellent livestock meat, belongs to high-protein, low-fat and low-cholesterol nutritional food, with social development and progress, mutton processing technology research draws attention from various countries, the existing mutton consumption mode is still limited to directly selling fresh products to consumers, and the production of mutton products with high added value can certainly attract more consumers.
