Embodiment 1
[0015] Embodiment 1: Subsequent drying mode is the production of seasoning dehydrated bamboo shoots (Ma bamboo shoots) of vacuum freeze-drying
[0016] Choose fresh moso bamboo shoots, first select, peel, wash, slice (4.5mm), soak (0.2‰ sodium sulfite, 0.5% malic acid) to obtain 25Kg (moisture content about 83% wet basis), press in water at 100°C Bamboo shoots and water 1: 10 were blanched for about 10 minutes, then cooled rapidly with cooling water, carried out conventional hot air convection drying, to a weight of 4.52Kg (moisture content 6%), then at 80 ℃ seasoning liquid (0.5% salt, 5 % glucose) for 60 minutes, to a weight of 6.54Kg (moisture content 35%), frozen in a freezing room at -35°C for 5 hours, and then vacuum freeze-dried (absolute pressure 550Pa) at 70°C for about 5 hours to If the moisture content is below 6%, then select, classify, and conduct metal detection, then carry out nitrogen-filled packaging and storage of various specifications as required.
Embodiment 2
[0017] Example 2: Production of Seasoned Dehydrated Edamame with Vacuum Microwave Drying as Subsequent Drying Mode
[0018] Select fresh edamame, firstly select and peel the edamame to obtain 25Kg of clean edamame (moisture content about 78% wet basis), adjust the pH to 7-7.5 with NaHCO3 to protect the color, and pre-blanch in a ZnCl2 solution with a total concentration of Zn2 + 0.05% for 5 Minutes, then quickly cooled with cooling water, and carried out conventional hot air convection drying (85°C, 4-5 hours, turn to 60°C, 6-8 hours), to a weight of 5.9Kg (moisture content 7%), and then seasoned at 80°C (0.5% salt, 8% glucose) in rehydration for 30 minutes, to a weight of 6.9Kg (water content 20%), then carry out vacuum microwave drying (absolute pressure 660Pa) at 70 ° C for about 5 minutes, to a weight of 5.9Kg (moisture content 20%) rate of less than 7%), and then select, classify, and carry out nitrogen-filled packaging and storage of various specifications as required af...
