Embodiment 1
[0020] Embodiment 1: Production of high colloidal sea cucumber dried products
[0021] Cut the sea cucumber (collagen content in the surface layer 78%) abdomen 1 / 4 body length from the anus, cut the opening about 1 / 4 body length parallel to the sea cucumber body, remove the internal organs of the sea cucumber, and remove the attachment to the inner wall Wash the inner cavity of the sea cucumber with clear water, then treat the surface of the sea cucumber until it is clean, with an initial moisture content of 88.6%, and set aside. Pre-boil in 100°C water for 20min, after cooling, freeze in -25°C quick freezer for 1 hour, then vacuum freeze-dry (vacuum degree 50Pa, clapboard temperature 60°C, dry for 8h, dehydrate to moisture content 35% (wet basis), and then The material is moved to a vacuum microwave drying chamber with a microwave power of 1.8W / g, a drying pressure of 30kPa, and a drying time of 40min until the moisture content is below 7% (moisture basis), packed and stored ...
Embodiment 2
[0022] Embodiment 2: production of dried squid with high colloidal surface layer
[0023] Cut the fresh squid (the collagen content in the skin is 90%) along the center line of the abdominal cavity, so that the meat slices on both sides are symmetrical. The incision should be about 1cm away from the fish tail. Remove the ink sac. Slant a knife on each side, cut the eyeball, and let the eye fluid flow out to facilitate drying. Put the meat slices on both sides of the abdominal cavity, remove the viscera, then rinse, remove dirt and mucus, drain the surface water, pre-boil in 100°C water for 30 minutes, and freeze in a -25°C quick-freezer for 1 hour after cooling, then vacuum freeze-dry (vacuum Temperature 50Pa, partition temperature 70℃, dry for 10h, dehydrate to moisture content 40% (wet basis), then move the material to vacuum microwave drying room, microwave power 2.2W / g, drying pressure 20kPa, drying time 50min, until moisture content Below 7% (moisture basis), packaged an...
