Problems solved by technology

[0008] The production of the above-mentioned heme is all directly produced by fresh blood. Due to the limited time of blood preservation, the water content in the blood is very high, which greatly increases the use of organic solvents and production costs in the production of heme.

Embodiment Construction

[0020] Based on systematic research on the physicochemical and functional properties of goat fluid and obtaining the best production conditions for producing hemoglobin using blood cell powder, the present invention is verified by experiments, and the method is used to extract 7.0-8.5g from 1kg of blood cell powder with a purity of 95-97% % of heme, the organic solvent recovery rate is 98-99.9%.

[0021] Fig. 1 shows the production process flow diagram of sheep blood heme. Take fresh sheep blood for centrifugation to obtain plasma and blood cells, use spray drying method to dry blood cells into blood cell powder, dissolve with acetone, extract, stir, adjust pH, filter to remove precipitation, separate to obtain supernatant, distill and dry to obtain blood red Vegetarian products.

[0022] Below in conjunction with the accompanying drawings, the present invention will be further described by way of example embodiments.

[0023] Example 1. Taking 10 kg of blood cell powder as ...

Abstract

The invention discloses a method for preparing heme of sheep blood, belonging to field of foodstuff and foodstuff additive. It comprises following steps: taking fresh sheep blood as raw material, separating through centrifugation, getting plasma and blood cell, spray drying blood cell into blood cell powder, dissloving with acetone, extracting, stirring, moderating pH, filtering to remove deposition, separating and getting supernatant, drying through distilling and getting heme. The invention is characterized by simple process, reduced equippment investment by 25- 35%, high organic disslovant recovery rate of about 98- 99.9%, low production cost, reduced about by 40- 60%, and high purity heme of about 95- 97%. The quantity of heme extracted from each 1kg blood cell powder is 7.0- 8.5g.

Description

technical field [0001] The invention belongs to the scope of food and food additives, and in particular relates to a production method of sheep heme. Background technique [0002] Heme is the red pigment in the blood and muscle of higher animals. Its basic structural component is porphine composed of pyrrole, which forms porphyrin after being attached with a side chain, and then forms an iron porphyrin compound with a molecule of ferrous iron, which is heme . In hemoglobin and myoglobin, heme accounts for about 3.8%, and the heme content in whole blood is about 0.5%. Heme is one of the important products obtained from the deep processing of sheep blood. At present, there are many research reports on the production methods of heme, mainly including: [0003] 1. Song Zhaojun, Zhang Yansheng, Liu Xi. Research on New Technology of Heme Extraction and Purification from Pig Blood. Meat Processing, 2004, (8): 23-25. Description: The extraction process of hemoglobin in pig red b...
