The invention discloses a method for producing instant
straw mushroom chips by adopting a vacuum low-temperature
dehydration technology, and belongs to the technical field of
deep processing of agricultural products. The method for producing the instant
straw mushroom chips comprises the following main processes of: performing pretreatments such as conventional picking, cleaning, segmenting,
blanching, non-
sulfur color protecting, ultrasonic aid impregnating,
sodium alginate
film coating and the like on fresh
straw mushrooms, and then, performing hot air and vacuum frying combined dehydrating, centrifugal oil removing,
seasoning and packing. By adopting the new processes of non-
sulfur color protecting, ultrasonic aid impregnating,
sodium alginate
film coating and hot air and vacuum fryingcombined dehydrating, the
oil content of the product is remarkably reduced while the sensory quality of the product is improved and the impregnating efficiency is increased. In the method, necessary freezing treatment in the conventional fruit and vegetable
chip frying process is not needed, so that the
processing time is greatly reduced, and the production period of the product is effectively shortened. The product obtained by using the method has the characteristics of high puffing rate, low
oil content, good sensory quality and the like; and a feasible new path is provided for
deep processing utilization of the straw mushrooms.
