Problems solved by technology

[0002] Konjac is a special economic crop with high economic value. Konjac powder has been widely used in food, medicine, petroleum, chemical industry, textile and other industries, but konjac is prone to browning during dehydration and baking, and browning It is very serious. In order to control browning, sulfur dioxide gas fumigation is generally used in production to prevent it. This processing method not only seriously pollutes the environment, but more importantly, the residue of sulfur dioxide in subsequent konjac products seriously exceeds the standard, which is not only harmful to human health, but also serious. Affect the competitiveness of konjac powder in the international market

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a sulfur-free drying method in dried konjac dehydration roasting. Background technique [0002] Konjac is a special economic crop with high economic value. Konjac powder has been widely used in food, medicine, petroleum, chemical industry, textile and other industries, but konjac is prone to browning during dehydration and baking, and browning It is very serious. In order to control browning, fumigation with sulfur dioxide gas is generally used in production to prevent it. This processing method not only seriously pollutes the environment, but more importantly, the residue of sulfur dioxide in subsequent konjac products seriously exceeds the standard, which is not only harmful to human health, but also serious. Affect the competitiveness of konjac powder in the international market. Contents of the invention [0003] The object of the present invention ...
