Description

Meat improvement method of broiler with excellent processability

1 is a graph showing the fragmentation rate of muscle fibers over time after the present invention and conventional broiler muscles, and FIG. 2 is a graph showing the change in physical properties (shearing force) of the meat over time in the present invention and conventional broiler muscles.

The present invention relates to a method for improving meat quality of broilers with excellent processability, and more particularly, to a method for improving broiler meat by feeding broiler compound containing chitosan and drinking water to broilers.

Common broiler feeds are the initial broiler feed (feed from 1 to 7 days of hatching), 21% or more crude protein, 3.5% or more crude fat, 6.0% or less crude fiber, and up to 7 days or 20 days after hatching. The feed has 19% crude protein, more than 2.6% crude fat, less than 6.0% crude fiber, more than 3005 Kcal / kg of ME (metabolizable energy), and the late broiler feed (feed until 20 days after hatching) is crude protein. 17% or more, crude fat 2.5% or more, crude fiber 6.0% or less, ME 3080 Kcal / kg or more.

On the other hand, as a drug that affects the metabolism of livestock, it has the characteristics of a nutrient, such as vitamins, calcium, sugars, blood substitutes, minerals and organic acids.

In addition, antibiotics are added to prevent disease and improve feed efficiency, and recently, lactic acid bacteria are used for the same purpose.

However, these feeds and nutritional supplements are administered for the growth and nutritional status of broilers and not only improve the meat quality, but also had the disadvantage that the meat quality is lowered compared to the native chickens of Korea.

On the other hand, chitosan is a derivative of chitin, and chitin is a polysaccharide contained in shells of shellfish such as shrimps and crabs, upper shells of upper layers, exoskeletons of arthropods, organs of molluscs, fungi, yeast, mushrooms, and cell walls of fungi. It is a kind of protein and exists as a glycoprotein in vivo.

Chitosan is a substance linked by β-1, 4 bonds of glucosamine pyranose units formed by the removal of acetyl groups by chemical or biological treatment from chitin.

Chitin and chitosan have almost the same molecular structure, are easily soluble in weak acids, are easily absorbed by the action of enzymes, and become cations in the dissolved state. Chitin was discovered in 1811, and since 1986, the characteristics and functions of chitin-chitosan have been discovered in Japan, and its use has been developed.

Particularly noteworthy is the medical action for the growth and maintenance of plants and animals, humans and other diseases, prevention and treatment of diseases.

According to the literature, chitosan is called a functional food because it has a function similar to a drug, and has the following effects.

① Suppression of aging: makes old cells become active by making them active.

② strengthen immunity: strengthens immune cells that prevent invasion and proliferation of bacteria, viruses, cancer cells, etc.

③ Disease prevention and recovery: It gives vitality to the weakened somatic cells and immune cells and activates the healing power of the living body.

In addition, according to the high-tech chitin and chitosan of the high-tech material of reference Kim Yong-bum, LDL cholesterol lowering level (59p), immune resiliency effect, oligosaccharide immunoreactivity effect, antacid and digestive accelerator (85p), wastewater Treatment field (coagulant, heavy metal adsorbent, dye purifier, 86p), cosmetic field (87p), food field (cholesterol lowering agent, preservatives, repair and moisturizer, food coating and packaging agent, and low calorie weight agent, 89p), agriculture field ( Soil modifier, improved egg production, 98p).

However, the above-mentioned various documents and technical configurations do not mention or imply the use of chitosan as a feed additive for improving meat quality, and are greatly different from the basic technical configurations of the present invention.

Accordingly, it is an object of the present invention to provide a broiler meat improvement method having excellent processing suitability by incorporating chitosan-containing blended feed and drinking water into broiler chickens.

The method of the present invention for achieving the above object is 0.1 ~ 1 weight of additives mixed with 99 ~ 99.9 wt% of general blended feed and chitosan, charcoal powder and less than 10 mesh (grain) in a weight ratio of about 1: 1: 1 It is composed of feeding a blended feed containing% to broilers and drinking drinking water containing chitosan.

Looking at the present invention in more detail as follows.

As described above, chitosan has low LDL cholesterol, immune responsiveness, oligosaccharide immune responsiveness, antacids and digestion accelerators, wastewater treatment (coagulants, heavy metal adsorbents, dye purifiers), cosmetics, and food (cholesterol lowering agents). , Preservatives, refining and moisturizers, edible coatings and packaging agents, and low calorie weight agents, used in agriculture (soil improver, poultry laying rate improvement), but references to meat improvers are not shown in any literature.

The present inventors have found that the chitosan functions as a meat improver of the broiler, and this will be described in the following examples, but the chitosan is determined to be effective not only for the broiler but also for livestock such as pork, beef cattle, and the like. It is included in the scope of the present invention.

On the other hand, the compounded feed according to the present invention is prepared by mixing 0.1-1% by weight of a mixture of chitosan, charcoal powder and less than 10 mesh fine sand in a weight ratio of about 1: 1: 1. In addition, 0.5 to 2% by weight of chitosan powder was dissolved in 0.3 to 1% by weight of glacial acetic acid, and diluted with 5 to 10 ppm of a 1% by weight aqueous solution of chitosan, to which 97 to 99% by weight of purified water was added, and supplied as negative water. At this time, the effect is less than 5ppm, and if more than 12ppm compared to the amount of chitosan used, the effect of improving the meat is low.

The chitosan used in the present invention is a pale yellow powder composition, and water-soluble substances having 10% or less of moisture, 1.0% or less of ash, and 50 mesh or less of particles are preferably high purity chitosan having a deacetylation degree of 90% or more. At this time, if a small amount of chitosan is added, the meat quality improvement effect is insignificant.

The charcoal powder is sold on the market baked with oak, it is preferable that the water content is low and the particle size is less than 50 mesh. The charcoal powder is a wood carbon baked at a high temperature of more than 800 ℃ in a charcoal kiln as a raw material of hard wood, it is electrically good conductor and has the function of reducing all the surrounding materials.

These charcoal functions have been scientifically proven, and if a person has an upset stomach or lack of energy, they may be taken in small doses with folk remedies.

The fine sand used in the present invention is preferably 50 mesh or less with particles removed from soil, impurities and the like by sand sand from the river.

The reason why the fine sand sand is added is to promote digestion, strengthen stomach wall, or to ingest various components (silicon, calcium) contained in sand.

The present inventors add that chitosan powder, charcoal powder, and fine sand additives to commercial broiler compound feeds of 99 to 99.9 wt% and drink the chitosan solution therein to improve the quality of the initial (4 to 6 week old) broilers. there was.

Therefore, in the present invention, by using a commercially available broiler feed in large quantities to change the meat quality of the broiler to a tender and excellent processing ability, the broiler stable production of broilers to improve the quality than other chickens By activating high quality meat production and processing chicken, processors such as chicken produce high quality meat products that can secure the consumption market and guarantee profits by producing products with improved taste and quality. Could produce.

Although the effects of the present invention are described in more detail with reference to the following examples, the scope of the present invention is not limited to the following examples.

EXAMPLE

Broiler Harvard was selected as the subject livestock, and the experiment was conducted while breeding up to 7 weeks immediately after hatching. The breeding environment was not specially designed and the breeding was carried out under general broiler breeding conditions. The broiler group was divided into half and each group was divided into two groups: a diet fed with chitosan and the like (see Table 1 below), and a control group fed with a diet (excluding table 1) and water (see Table 1). During the fifth week of breeding, the samples were slaughtered and the meat was inspected, and the results are shown in FIGS. 1 and 2.

As can be seen in FIG. 1, the meat quality test results of broiler chickens slaughtered at 5 weeks of breeding were evaluated by meat quality test method by varying the length of muscle fibers under the microscope immediately after slaughter. It was much higher than the 43% fragmentation rate of the control, resulting in meat softening effect of about 0.6 times. This can be confirmed that there is a significant improvement in meat quality compared to broilers fed general formula feed.

On the other hand, Figure 2 is a result of measuring the physical properties using a method of measuring the shear force of broiler samples immediately after the slaughter of the broiler group slaughtered 5 weeks. From FIG. 2 the shear force of the embodiment is 146 g / cm Shearing force of control 273g / cm Compared to that, there was about 87% meat softening effect.
