Embodiment 1
[0029] Step A, bird's nest removal of impurities: the bird's nest raw material is put into the 1.0wt% sodium bicarbonate aqueous solution of 10 times of its dry weight mass, the water temperature is 80 ℃ during foaming, soaking for 6h, removing the bird's hair, and cleaning 3 times;
[0030] Step B, ripening: take by weighing the bird's nest after soaking and washing in step A, add deionized water three times its dry weight mass, stew at 100° C. for 30 minutes;
[0031] Step C, concentration: the bird's nest after the sufficient water absorption and ripening is carried out low temperature rotary evaporation vacuum concentration, concentrated once, the bird's nest water absorption ratio after the concentration is 5 times, and the solution viscosity is 72mpa s;
[0032] Step D, molding: the concentrated bird's nest concentrate is extruded and molded with an air compressor;
[0033] Step E, drying: vacuum-drying the shaped bird's nest again, the vacuum drying temperature is 60°C,...
Embodiment 2
[0035] Step A, bird's nest removal: put the bird's nest raw material into the 0.01wt% vitamin C aqueous solution of 30 times of its dry weight mass, the water temperature during foaming is 20 ° C, soaking for 3h, removing the bird's hair, and cleaning 5 times;
[0036] Step B, ripening: Weigh the bird's nest after soaking and cleaning in step A, add deionized water 100 times its dry weight, steam and ripen at 180° C. for 5min;
[0037] Step C, concentration: the bird's nest after the sufficient water absorption and ripening is carried out low temperature vacuum infrared concentration, when concentrated to the bird's nest water absorption multiple 30 times, then add the deionized water of the bird's nest dry weight 10 times, repeat the concentration, and the number of times of concentration is 2 time, the water absorption ratio of bird's nest after concentration is 40 times, and the solution viscosity is 5mpa s;
[0038] Step D, molding: the concentrated bird's nest concentrate...
Embodiment 3
[0041] Step A, bird's nest removal of impurities: the bird's nest raw material is put into the pure water of 15 times of its dry mass, the water temperature is 40 ℃ during soaking, soaking for 8h, removing the bird's hair, and cleaning 8 times;
[0042] Step B, ripening: take by weighing the bird's nest after soaking and cleaning in step A, add pure water 5 times its dry weight mass, and heat at 130° C. for 5min by microwave heating;
[0043] Step C, concentration: the bird's nest after the sufficient water absorption and aging is carried out low temperature rotary evaporation vacuum concentration, when concentrated to the bird's nest water absorption multiple 5 times, then add the deionized water of the bird's nest dry weight 5 times, repeat the concentration, the number of times of concentration is 5 times, the water absorption ratio of bird's nest after concentration is 2 times, and the solution viscosity is 90mpa s;
[0044] Step D, shaping: the concentrated bird's nest co...
