Due to the special effects of plasma protein powder, so the domestic high-grade suckling pig feed gradually in use, it is indeed possible to reduce the incidence of diarrhea, increase daily gain and improve piglet's body resistance and the like. But because of its expensive, complicated process, and the current market shortages in China, plasma protein powder material than a dozen manufacturers, large and small, to fish, but few manufacturers actually do good, so there is in the product quality great variation, even the possibility of adulteration, the following common errors one by one: 1, the water-soluble Analysis: As the real high-quality plasma protein powder is pure plasma spray drying, so it should be 100% Water-soluble, water-soluble aqueous solution fast and after the appearance of pale yellow, complete solution clarification. Low quality plasma protein powder are common in isolated soy protein or add protein powder, or plasma and other blood cell separation is not complete, although the level of plasma protein content increased, but poor aqueous solubility, water-soluble very slow, and visible water-soluble After excessive insolubles floating above or deposited on the bottom. 2, see the appearance of analysis: First, many manufacturers because of the plasma and blood cell separation is not complete (or malicious cost reduction of plasma proteins) so the performance of plasma protein powder reddish color, due to the blood cells in the blood plasma protein powder mixed into plasma protein protein meals increase, increase production, but its value is greatly reduced, but the manufacturer of the recovery can be improved, and therefore cost reduction; second is to use a water-soluble test to identify, mixed with blood globulin products whose solution is red and insoluble material in the presence of water. After the real high-quality pure water-soluble plasma protein powder should look clear, yellowish complete solution. 3, amino acid analysis: Amino Acids in your balance, to analyze whether the total amino acid content and balance to identify. 4, crude protein analysis: imported plasma protein powder, because of its production process added to the process and the reverse osmosis concentrate ash and other special process, thereby increasing the protein content (content 76% -82%), and thus lower the recovery rate , relatively better quality, higher value, high-end quality of goods. Domestic process to achieve this level of only one (XF-77). In addition to this domestic manufacturers more than the protein content of the process is at 70-75% more than the protein content should be combined with water-soluble and appearance to determine to see if adding additional protein material. Low quality plasma protein powder protein content of less than 72 percent more. More performance in high ash content, such as more than 14 percent and so on. High crude protein alone does not explain the problem (blood cells that may be contaminated), it should be combined with the appearance, ash and water-soluble to identify. 5, denatured protein analysis: protein after high temperature spray drying the moment, whether degeneration has long been a focus of professional animal nutritionist and creep feed manufacturers concerned, in general, the average temperature will not only lead to protein denaturation, will make Special active protein such as an immunoglobulin activity loss. Simply put here a discriminating way: take samples plus the amount of water placed in the oven at 100 ℃ modulation wait 10-15 minutes out, high-quality plasma protein powder should be frozen state, and sets the color of the stain has been free of any impurities; low quality plasma protein powder will be different colors or impurities spots appear or brownish color component (mixed blood cells and impurities sake) color. 6. Determination of immunoglobulin content: Although the domestic immunoglobulin content in the feed industry measurement method provides no uniform industry regulations, but vision, relative to the strict quality requirements of the manufacturer usually issued two (only two In contrast only stable sense) have certain significance test report.
