Embodiment 1

[0006] Take by weighing 20kg of paphia clams, microwave the shell to open, and take out the clam meat. Grind the clam meat with a biological grinder, then put it into a pot, add 3 times the volume of water and boil for 1 hour, then separate the liquid from the solid, add 1 times the volume of water to the residue and boil for half an hour, separate the liquid and solid again, twice The supernatants were combined and the residue was retained. The supernatant is heated and concentrated to one-sixth of the original volume, and the pH is first adjusted to 3 with 3mol / L hydrochloric acid. There is acidic protein precipitation, and the liquid-solid is centrifuged. The supernatant is adjusted to pH 9 with 3mol / L NaOH solution. Alkaline protein precipitation, liquid-solid centrifugation, then adjust the pH of the supernatant to 5, let it pass through 100×10cm Na + Strong acid ion exchange column, eluted with distilled water, the flow rate is 25ml / min. Take the effluent of the 2nd to...

Embodiment 2

[0008] Weigh 10kg of scallops, mince them with a biological grinder, put them into a pot, add 3 times the volume of water and boil for 1 hour, then separate the liquid from the solid, add 1 times the volume of water to the residue, boil for half an hour, and separate the liquid from the solid again , the two supernatants were combined, and the residue was retained. The supernatant is heated and concentrated to one-sixth of the original volume, and the pH is first adjusted to 3 with 4mol / L hydrochloric acid. There is acidic protein precipitation, and the liquid and solid are separated by centrifugation. The supernatant is adjusted to pH 9 with 5mol / L NaOH solution. Alkaline protein precipitation, liquid-solid centrifugation, then adjust the pH of the supernatant to 5, and pass it through a column with a volume of 5.0L Na + Weak acid ion exchange column, eluted with distilled water, the elution speed is 25ml / min, take 5000 ~ 20000ml of effluent, this part of effluent contains a ...

Embodiment 3

[0010] Weigh 20kg of mussels, freeze them to minus 24 degrees to open their shells, take out the shellfish, grind them with a bio-shredder, then put them into a pot, add 3 times the volume of water and boil for 1 hour, then separate the liquid from the solid, and add one more to the residue Double the volume of water was boiled for half an hour, the liquid and solid were separated again, the two supernatants were combined, and the residue was retained. The supernatant is heated and concentrated to one-sixth of the original volume. First, adjust the pH to 3 with 6mol / L hydrochloric acid. Acidic protein precipitates, and the liquid and solid are centrifuged. The supernatant is adjusted to pH 9 with 6mol / L NaOH solution. Alkaline protein precipitation, liquid-solid centrifugation, then adjust the pH of the supernatant to 5, and pass it through a column with a volume of 5.0L Na + Weak acid ion exchange column, eluted with distilled water, the elution speed is 25ml / min, take 5000 ~...

Abstract

The invention provides the preparation method of multifunctional feedstuff additive by using shell manufacturing leftover bits and pieces as the raw material, wherein two products of fresh flavor agent and feed addictive can be prepared, the process comprises the steps of excorticating, fragmenting biological tissue, extracting through water boiling, removing alkaline protein with hydrochloric acid and NaOH solution deposition, liquid-solid separating, adjusting pH to be 4-5, disintegrating through ion exchange process and enriching, distilled water eluting, collecting the effluent liquid, drying and disintegrating the solid body.

Description

technical field [0001] The invention relates to a feed additive, and mainly relates to a method for producing a multifunctional feed additive by utilizing low-value shellfish such as clams and mussels and shellfish processing leftovers. Background technique [0002] Puffy clam is the shellfish with the highest yield in Guangdong in recent years, and its output has increased dramatically year by year; and the emerald mussel (Pernaviridis) is the main traditional shellfish species in Guangdong, with a very high natural breeding yield. As the market of these two kinds of shellfish is close to saturation, the price drops, and the purchase price is 0.6 yuan / Kg and 0.30 yuan / Kg respectively. It has greatly dampened the enthusiasm of fish farmers, which has also seriously affected the development of shellfish farming in Guangdong. Especially if the prices of these two types of shellfish continue to be low, fish farmers are unwilling to harvest them and allow them to proliferate, w...
