Overview of processing technology of duck blood production line
material:
Duck blood 50kg; salt 0.8kg; sodium carboxymethyl cellulose 0.7kg; sodium citrate (anticoagulant) 0.5kg (blood collection and preparation 0.25); calcium chloride 1.0 kg (10kg dissolved water); water 48kg ( Soluble salt 4; carboxylic acid 17; blending 27)
Processing technology:
1, blood collection
Put 0.25kg of sodium citrate in the blood container in advance; put 50kg of duck blood; put it at 4~10 °C
Alternate in the library.
2, filter
The duck blood after cooling was filtered through a mesh of 10 mesh or more to remove a small amount of clots.
3, ingredients
With 0.25 kg of sodium citrate, 0.7 kg of sodium carboxymethylcellulose, 0.2-2% calcium chloride (combined solution),
Mix well with 27kg of water.
4, filling, vacuum degassing package
After the ingredients dispensed into the fixed shape duck cassette; solidified under vacuum conditions heat package.
5, sterilization
The encapsulated duck blood is sterilized in hot water at 60-90 ° C for 30-140 min (or autoclaved for 5-40 min ).
6, storage
The sterilized duck blood is naturally cooled and tested, and the qualified product is stored at 0-4 °C. Shelf life is 1 month.
distinguish
When buying duck blood, first look at the color, the real duck blood is dark red, while the fake duck blood is generally brown. The true duck blood has undergone high-temperature degassing and deodorization during processing, and there is no bloody smell, but a duck-like fragrance floats; the fake duck blood has a honeycomb stomata after it is opened, and starch is often added during processing. And some other Chemicals, so generally have toughness and can stretch. True duck blood is more brittle.
1, the real duck blood is delicate and tender, the chopsticks are fragile, and the fake duck blood is relatively rough, and the chopsticks are not broken.
2. After using a napkin to blot a piece of duck blood, if it becomes very tough like plasticine, it is fake duck blood.
3, true duck blood and fake duck blood ratio, dark color, good elasticity, and there is a strong smell.
In general, the fake duck blood has a gelatinous texture, is not easy to break, the color is similar to the red brick color, and the cross section mostly has honeycomb shaped holes. The real duck blood is dark red, with sparse holes and extremely fragile
