Embodiment 1
[0025] Wash with tap water to remove the soil and impurities on the surface of the yam, cut the yam into sections and put it on a microwave plate, heat it quickly with 800W power for 3 minutes, remove the skin, roots and damaged brown spots after natural cooling, and then cut into pieces with a slicer Thin slices with a thickness of 2mm were then frozen in a -60°C freezer for 1h. Place the frozen yam slices on a microwave plate, and quickly ripen them with 800W power for 2 minutes, then spread them on the separator in a single layer, put them in a blast drying oven at 65°C, and dry them until the moisture content on a wet basis is 4%~ 10%, after the product cools down, it will be sealed and packaged in a high-barrier food-grade aluminum foil composite bag to ensure the crispness of the product.
Embodiment 2
[0027] Wash with tap water to remove the soil and impurities on the surface of the yam, cut the yam into sections and put it on a microwave plate, heat it quickly with 1000W power for 3 minutes, remove the skin, roots and damaged brown spots after natural cooling, and then cut into pieces with a slicer Thin slices with a thickness of 4 mm were frozen in a -40°C freezer for 2 hours. Put the frozen yam slices on a microwave plate, and quickly ripen them with 1000W power for 1min, spread them on the separator in a single layer, put them in a blast drying oven at 75°C, and dry them until the moisture content on a wet basis is 4% to 10 %, immediately after the product is cooled, it is sealed and packaged in a high-barrier food-grade aluminum foil composite bag to ensure the crispness of the product.
Embodiment 3
[0029] Wash with tap water to remove the soil and impurities on the surface of the yam, cut the yam into sections and put it on a microwave plate, heat it quickly with 1200W power for 1min, remove the skin, roots and damaged brown spots after natural cooling, and then cut into pieces with a slicer Disc-shaped yam slices with a thickness of 5mm were frozen in a -80°C freezer for 3h. Put the frozen yam slices on a microwave plate, and quickly ripen them with 1200W power for 1min, spread them on the separator in a single layer, put them in a blast drying oven at 90°C, and dry them until the moisture content on a wet basis is 4% to 10 %, immediately after the product is cooled, it is sealed and packaged in a high-barrier food-grade aluminum foil composite bag to ensure the crispness of the product.
[0030] The original flavor yam crisp chip that embodiment 1-3 makes adopts sensory evaluation method, from mouthfeel, form, smell, color and luster four aspects, and according to smel...
