Abstract

The invention discloses a method for processing crunchy white radish strips. The method comprises the following steps of: step 1, cutting a white radish into strips with a length of 3-5cm and a thickness of 0.5-1cm to obtain white radish strips; step 2, blanching the white radish strips at a temperature of 95-100 DEG C for 10-30s, and then cooling the blanched white radish strips to 30-40 DEG C at a cooling rate of 10-16 DEG C / min; step 3, freezing the cooled white radish strips at a temperature of 70-80 DEG C for 1-3h, and then immersing the frozen white radish strips in a maltose syrup solution with a mass concentration of 40-60% at a temperature of 50-70 DEG C for 3-8h; step 4, drying the white radish strips treated in step 3; and step 5, puffing the dried white radish strips to obtain the crunchy white radish strips, wherein the conditions for puffing the dried white radish strips are that the puffing temperature is 90-100 DEG C, the puffing pressure is 0.2-0.3 MPa, the dead time is 8-10 min, the puffing times is 3-5 times, the evacuation temperature is 65-95 DEG C, and the evacuation time is 1-2h.

Description

technical field [0001] The invention relates to crisp white radish strips and a processing method thereof. Background technique [0002] White radish, root vegetable, cruciferous radish plant. White radish is white in color, belongs to gold, enters the lungs, is sweet and pungent in nature, and returns to the lung and spleen meridian. Indications for lung impotence, lung heat, constipation, vomiting blood, flatulence, food stagnation, indigestion, excessive phlegm, constipation, etc. It can be eaten raw or cooked, and its taste is slightly spicy. However, white radish is bulky, heavy, difficult to store, difficult to transport, and because its taste is not very good, many people do not eat or buy white radish or its processed products, how to increase the sales of white radish or its products is to promote its sales Added a big problem. Dried fruits and vegetables are loved by many consumers because they are easy to preserve, nutritious and delicious, and can be eaten as...
