Abstract
The invention discloses extracted corn protein which takes corn soaking water generated in the process of producing corn starch by traditional technology as raw materials and is produced through physical-chemical precipitation, separation, evaporation and drying. The protein product of the invention is rich in kinds of amino acid, reasonable in composition proportion and high in nutritive value, contains lots of essential amino acids required by human bodies and animals, not only can be used as animal feeds but also can be used as composition of culture media to culture microorganisms. The production technology of the invention not only produces no pollutants, but also perfectly solves the problem of corn water pollution in the process of producing the corn starch and lightens the environmental protection pressure, thus being an environment-friendly production method which changes wastes into valuables.
Description
Technical field
The present invention relates to a kind of is the corn lixiviate albumen of raw material production with the soak water of maize, the invention still further relates to its production method.
Background technology
The indispensable amino acid of animal proteinum is balance relatively, but animal protein is mainly derived from foods such as meat, fish, milk, egg, these foods are on the one hand because price is more expensive, contain more saturated fatty acid that easily causes cardiovascular disorder and cholesterol owing to meat product on the other hand, thereby be unfavorable for health.
Along with the production-scale continuous expansion of domestic W-Gum, the amount of soak water of maize constantly enlarges, and has produced a large amount of waste water such as soak water of maize at present.The processing mode of corn water waste water has: 1. directly discharging, because its CODcr content is up to 12000～15000 mg/litre, and can serious pollution of water environment, for institute of country does not allow, also wasted available protein powder simultaneously; 2. handle by certain mode, this has not only wasted available protein powder, and returning enterprise has increased the cost of handling waste water.Development along with starch industry and product downstream industry, a large amount of soak water of maize becomes the burden of enterprise, and increase burden to environmental protection, the invention of the environment-friendly type production technology that this turns waste into wealth has perfectly solved this problem, not only obtained nutritious lixiviate albumen, and the waste water that is produced reaches the requirement of international sewage second-level emission standard.
Summary of the invention
The objective of the invention is to overcome shortcoming of the prior art, the soak water of maize that adopts traditional technology to produce the W-Gum generation is a raw material, through the albumen that physics and chemistry precipitation, separation, evaporation, drying form, corn lixiviate albumen of the present invention is rich in the required necessary amino acid of humans and animals such as Methionin, Threonine, methionine(Met).
Technical scheme of the present invention is: a kind of soak water of maize that utilizes is produced proteic method, and its content is:
(1) primary sedimentation: soak water of maize stoste degree Beaume is 8Be °-9Be °, and pH is 3.0-4.0; Regulating its pH with sodium hydroxide is 6.0-6.5, stirs, and utilizes the difference of range protein iso-electric point to make the partial protein flocculation sediment earlier, is warming up to 80 ℃, is incubated after 30 minutes, and a solid-liquid separation obtains primary sedimentation albumen (paste);
(2) secondary sedimentation: through one heavy after the liquid degree Beaume be 4Be °-5Be °, pH is 6.0-6.5; Regulating its pH with calcium hydroxide is 8.0-8.5, stirs, and places 30 minutes, and the heavy albumen of a large amount of calcium is separated out, and secondary solid-liquid separation under the normal temperature obtains secondary sedimentation albumen (paste);
(3) evaporation concentration: liquid that will be after secondary sedimentation obtains protein concentrate, the temperature in the vacuum Concentrating Process through the triple effect vacuum concentration: one imitates 90 ℃-96 ℃ of temperature, and two imitate 80 ℃-86 ℃ of temperature, 70 ℃-76 ℃ of triple effect temperature; Vacuum tightness is: 0.08-0.10Mpa;
(4) drying: with gained one heavy albumen, two heavy albumen, protein concentrate drying, get white or light yellow protein powder, drying temperature is 80 ℃ in the drying process, vapor pressure 0.5MPa-0.7Mpa;
(5) mix:, get finished product after the packing primary sedimentation albumen, secondary sedimentation albumen and protein concentrate thorough mixing after drying.
The corn lixiviate albumen that the present invention utilizes aforesaid method to produce, its main ingredient and weight percentage are: protein 10%-50%, calcium 10%-30%, total phosphorus 5%-30%, amino acid has: Aspartic Acid 0.8-3.0%, Threonine 0.3-3.0%, Serine 0.2-3.0%, L-glutamic acid 1.0-4.3%, glycine 0.5-2.3%, L-Ala 0.5-3.9%, Gelucystine 0.06-0.36%, Xie Ansuan 0.29-3.2%, methionine(Met) 0.08-0.9%, tyrosine 0.07-0.80%, phenylalanine 0.08-0.9%, Methionin 0.1-1.8%, Isoleucine 0.09-0.90%, Histidine 0.08-0.92%, arginine 0.04-0.78%, proline(Pro) 0.26-2.63%, leucine 0.2-3.0% also contains other constituents such as starch etc.
The invention has the beneficial effects as follows: protein product rich amino acids of the present invention, proportion of composing is reasonable, be of high nutritive value and contain a large amount of human bodies and the required necessary amino acid of animal, not only can be used as animal-feed and use, the moiety that also can be used as substratum is used for the cultivation of microorganism.Production technique of the present invention does not only have the generation of pollutent, and has perfectly solved the pollution problem of corn water in the W-Gum production process, has alleviated environmental protection pressure, is a kind of environment-friendly type production method of cleanliness without any pollution of turning waste into wealth.Technical solution of the present invention is a raw material with the corn water of thinking refuse all the time, when reducing the Starch Production cost greatly, turns waste into wealth, for contribution has been made in environmental protection.
