Abstract
Description
The present invention relates to a method for producing food for pets using salmon, and more particularly, to a method for producing a food for pets using salmon, which comprises extracting oil from salmon using high pressure carbon dioxide as a solvent capable of dissolving astaxanthin dye and omega- High-protein salmon powder, and a method for producing the salmon oil and the salmon powder, both of which are made available as feeds for pets or snacks.
Salmon is a species that has been eaten for a long time by humankind because of its excellent nutritional value, which is called super food. Therefore, in countries such as Norway and Chile, a large amount is cultured, and it is imported into frozen or refrigerated state with the intestines removed. In Korea, processed salmon raw materials are processed for fillet, slice, sushi, and for grilling. In this process, about 30% of by-products are produced, which can be used for pet food or snack to create a lot of added value. However, because it is more oily than other fish species, it can not be easily made into powder by drying. When dried and crushed, the oil contained in the meat is spilled out to form a powder, which does not become a powder.
Especially, polyunsaturated fatty acids such as DHA [docosahexaenoic acid] and EPA [eicosapentaenoic acid], which are mostly contained in the byproducts of salmon, have a problem in that they are difficult to use because they are easily oxidized due to high carbon number and high unsaturation . In particular, DHA and EPA have been reported to improve the quality of pets and to prevent, prevent and improve skin diseases.
Generally, the hot water extraction method, which is a method of extracting oil, requires separation of water and oil after extraction, and the separated oil must be further subjected to processes such as deoxidation, decolorization and deproteinization. In this process, And the polyunsaturated fatty acid is oxidized. The extraction method by hot pressing has a low extraction yield and a low yield. The extraction method using an organic solvent extracts other unnecessary components in the extract, and since the various organic solvents which are harmful to the human body are used, the probability that the residual solvent remains in the desired extract Is high. Also, since the amount of the organic solvent used is excessive, it presents many problems in terms of cost and environment.
Astaxanthin, a pigment present in salmon, is a pigment that has antioxidant activity and immunity - enhancing effect in addition to its functions, and has been attracting attention as a biofunctional substance. It has been reported that antioxidant ability is superior to alpha-tocopherol by more than 500 times. Astaxanthin has been reported to have anticancer effects, especially in pets.
A method of using high-pressure carbon dioxide as a solvent capable of extracting oil at a low temperature is attracting attention. High-pressure carbon dioxide extraction technology is a technology that uses carbon dioxide above critical temperature and critical pressure, and is attracting attention as a new environment-friendly cleaner technology that can replace existing processes in extraction, purification and related fields of pharmaceuticals, food processing and petrochemical refining have. In recent years, for the past 30 years, advanced countries have been using gas and liquids as a traditional process because of rising prices of energy resources, the environmental degradation of traditional separation processes, and the expansion of demand for special purpose new materials that can not be manufactured by gas or liquid processes. And has been concentrating on the development of new process technology that uses high pressure carbon dioxide as process fluid.
Although the initial high pressure carbon dioxide extraction technology has been mainly applied to natural materials extraction and purification, it has been limited to nonpolar materials such as spices, cosmetics, and fats, and low-priced foods and fragrance components. Recently, the development of various phenomenological characteristics and additional technologies Polar, small amount, and expensive natural drug extraction and purification. Carbon dioxide is colorless, odorless, harmless to the human body and chemically very stable. In addition, carbon dioxide exhibits a lower critical temperature (31.1 ° C) and a critical pressure (7.4 MPa) than any other fluid and can be easily adjusted to extraction conditions, thus having significant advantages in terms of energy efficiency as well as environmentally friendly properties. Furthermore, when this technology is applied in the field of separation and purification of natural biologically active materials, there is a problem in existing processes, namely, human toxicity due to organic solvents remaining in the final product, high cost, environmental pollution by waste solvent, Degeneration and low extraction selectivity can be solved or supplemented in a considerable amount.
Accordingly, the present invention relates to a method for producing astaxanthin pigment and omega-3 fatty acid-containing oil, high-protein and high-calcium powder for pets extracted from salmon using high-pressure carbon dioxide. It is expected that the oil will contain the astaxanthin pigment extracted simultaneously with the omega-3 fatty acid due to the characteristics of high pressure carbon dioxide, which is the extraction solvent, to improve the quality of the pet, prevent and prevent skin diseases, and have anticancer effect. Calcium and flesh proteins in salmon bones are processed into natural salmon without heat denaturation, so they prevent allergies caused by denatured proteins and play a role in the health of pets.
In order to achieve this object, the present invention provides a process for producing a salmon and a salmon processing product comprising the steps of: a) drying and then grinding salmon and salmon processing by-products; And b) extracting astaxanthin pigment and omega-3-containing oil extracts for pets and high-calcium, high-protein extracts from pet foods using high pressure carbon dioxide as a solvent from the pulverized product prepared in a) Of the powder.
According to the present invention, astaxanthin pigment and omega-3 fatty acid-containing oil, high-calcium and high-protein powder are produced at low temperatures and oil is collected at the same time in the separation tank, The weak pigment can be provided in a state of maintaining the functionality, and it can be utilized positively in the pet food and snacking field as a health functional material.
In addition, extraction time is greatly shortened compared with the conventional extraction methods such as milking and solvent, and more than 95% of the used solvent, carbon dioxide, is economical and environmentally friendly. And because there is no protein denaturation due to high temperature, the possibility of allergy is lowered and salmon processing by-products are used. Therefore, it is excellent in industrial availability and can provide high quality feed with high protein and high calcium.

b) extracting omega-3 fatty acid and astaxanthin pigment-containing oil at a temperature of 30 to 80 DEG C and a pressure of 70 to 700 bar using the high pressure carbon dioxide as the solvent, And recovering the high-protein, high-calcium salmon powder.
In the method of the present invention, the pulverized product of step a) may preferably be a vacuum lyophilized powder, and is free from naturally drying, cold air drying or vacuum drying. However, the omega-3 fatty acid can be prevented from oxidation, health-functional pigment and protein denatured, and drying at low temperature is preferable.
Also, in the method of the present invention, the high-pressure carbon dioxide extraction range of step b) may be a temperature of 30 to 80 ° C and a pressure of 70 to 700 bar, and most preferably 50 ° C, of 400 bar. Extraction under these conditions can extract omega-3 fatty acids in the highest yield. The apparatus for extracting oil includes a cooler for cooling the carbon dioxide introduced from the cylinder to 0 ° C or lower and converting the carbon dioxide into a liquid phase; A high pressure liquid pump for transferring the carbon dioxide to a high pressure state; A reactor capable of being sealed and capable of temperature control with a double jacket; And a separating tank for separating the carbon dioxide and the extract by injecting carbon dioxide containing the extract at a high pressure into a low pressure vessel.
