Because this method uses two fillings, although the box is turned upside down after sealing, it cannot completely guarantee that the duck blood and seasoned water have been completely mixed. If the two are completely mixed, the packaging box needs to be shaken vigorously; It has been basically filled with duck blood, and the air space is very small, so it needs to be shaken for a long time to achieve the mixing effect, and the operator cannot judge whether the materials in the box have been mixed.

Abstract
The invention discloses boxed duck blood and a preparation method thereof. The preparation method comprises the steps that the duck blood is pretreated; the duck blood is seasoned by seasoning water, wherein the seasoning water comprises the following components: 1-8wt% of salted duck egg white, 0.01-0.05wt% of onion and ginger sauce, 0.1-0.38wt% of sodium chloride, 0.02-0.3wt% of solidifying agent, and the balance of water; the seasoned duck blood is encapsulated, and then subjected to rough solidification, high-temperature sterilization and cooling; moisture is drained off; and then the duck blood is sent into a refrigerated warehouse. The salted duck egg white is added to the seasoning water, so that sodium chloride is supplemented in the duck blood, a taste of the duck blood can be improved, and the duck blood is more delicious and tasty. According to the preparation method, the duck blood is encapsulated and then directly sealed, and subjected to the rough solidification in a process that the duck blood is transferred into high-temperature sterilization equipment, and the transfer time is fully used, so that the technology time is shortened greatly, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the processing of livestock and poultry blood, in particular to boxed duck blood and a preparation method thereof. Background technique [0002] Duck blood is rich in protein and various trace elements such as iron, copper and calcium, among which the iron content is relatively high, and exists in the form of heme iron, which is easily absorbed and utilized by the human body. Duck blood has the functions of nourishing blood, clearing heat and detoxifying, and has the effect of preventing and treating iron deficiency anemia. Duck blood is rich in carbene acid, called duck blood oleic acid, which can prevent herpes zoster, stimulate muscles, and enhance immune function. [0003] The plasma protein in duck blood, through the digestion of the human stomach, decomposes a substance that can detoxify and smooth the intestines. It can chemically react with the toxic and harmful substances entering the body to reduce its toxicity and e...
