Embodiment 1

[0017] Embodiment 1: produce garlic vinegar

[0018] 1. Peel the garlic cloves and rinse them with running water;

[0019] 2. Take 1000kg of washed garlic cloves, float in warm water at 60°C~70°C for 20~30 minutes, remove and cool to room temperature quickly;

[0020] 3. Use a crusher to crush the washed garlic cloves into small pieces of about 1.5cm, add 500kg of water, and squeeze the juice with a juicer to obtain 1100kg of garlic juice;

[0021] 4. Heat the garlic juice to about 70 degrees, keep it warm for 25 minutes to sterilize, and wait for the garlic juice to cool to room temperature;

[0022] 5. Add 3 kg of glucoamylase, stir well, and carry out saccharification and fermentation at 25°C~30°C for 5~8 hours;

[0023] 6. Add 0.5kg of Saccharomyces cerevisiae, and carry out alcoholic fermentation at about 30 degrees for 5-7 days;

[0024] 7. Adjust the alcohol content of the fermented liquid to 7-8 degrees, transfer it to a fermenter, connect with 5% acetic acid bacter...

Embodiment 2

[0025] Embodiment 2: produce concentrated juice of black garlic

[0026] Garlic rice 500kg, cut into 3mm slices, put in a reaction kettle, add 1000kg of water, heat to 80°C, and keep warm for 48 hours. The temperature was lowered to 70°C and kept for 96 hours. Release the material, extract the juice through a plate and frame filter press to obtain 1320 kg of black garlic juice, add 13 kg of 1% chitosan acetic acid solution, stir and clarify, and filter through a plate and frame filter to obtain 1300 kg of clarified black garlic juice, after ultrafiltration Obtain 1400kg of black garlic juice, and the garlic juice is first concentrated to 600kg with a nanofiltration membrane. Then concentrated by evaporation under reduced pressure, controlled temperature 55°C~60°C, pressure -0.5MPa~-0.8Mpa, obtained 250kg black garlic concentrated juice.

Embodiment 3
