Description

The composition of improved Lactic acid bacteria feed additive and Method for manufacturing et al.

The present invention relates to a feed lactic acid bacterium for enhancing the antimicrobial effect and a method for manufacturing the same, and in particular, the conventional lactic acid bacteria are cultured for a predetermined time, followed by heat treatment by addition of bitine, followed by two steps of reculturing by adding a yucca extract. The present invention relates to a lactic acid bactericidal agent having an enhanced antimicrobial effect, comprising adsorbing a bactericidal culture solution to a conventional pharmaceutically acceptable adsorbent, and then mixing the same with an excipient and repeating the same. .

Probiotic is derived from the Greek word for life and, in contrast to antibiotic, refers to a beneficial relationship between living organisms and in the ecological term probiosis, meaning symbiosis. It was first used by Lilly and Stillwell (1965). Since then, many researchers have defined probiotics. Parker (1974) is a microbial and metabolite that has beneficial effects on the host through control of the intestinal microflora. It was. Mitsuoka (1975) and Crawford (1979) are probiotics that are microorganisms or cultures with moderate physiological activity, and antagonistically act against antagonistic bacteria in their intestines by administering them. It should be possible to guarantee that the gun is returned to normal. Fuller (1989) later defined probiotics as living microorganisms that benefit the host by improving the balance of intestinal microflora. In Korea, Probiotics are preparations containing live beneficial microorganisms in Korea, and they are settled in the intestines of animals and compete with other pathogenic microorganisms to inhibit the growth of harmful microorganisms and to help digestion and absorption of ingested feed. It is defined as a microbial agent that promotes growth and improves feed efficiency.

Probiotics have been recognized for their effects on abnormal fermentation, diarrhea, indigestion, and constipation in the intestine, and have been used for humans. They are widely used in various livestock species for the purpose of improving the intestinal environment, improving productivity, and preventing diarrhea. It has been used. Microorganisms currently used in probiotics include lactic acid bacteria, subtilis bacteria, molds and yeasts, and lactic acid bacteria isolated from the gut of healthy livestock are generally widely used.

In 1973, Tortuero reported that dietary supplementation of 100 chickens with Lactobacillus acidophilus for 11 days resulted in increased weight gain and improved feed efficiency (Poultry Sci., 52, 197). In 1982, Watkins et al. Found that Lactobacillus acidophilus was significantly reduced in E. coli-infected chickens compared to non-administered bacteria (Poultry Sci., 61, 1298). -1308). In 1989, Myung-Won Jae et al reported that when lactic acid bacteria were fed to pigs, the gain in body weight was improved and diarrhea in piglets was prevented (Korea J. Anim. Sci ,. 31, 318-323). In 1984, Reddy G.V et al. Reported that Lactobacillus acidophilus and Lactobacillus bulgaricus exerted antimicrobial activity as natural antibiotics (Cultured Dairy Product J. 7-11). Binek M et al. Then demonstrated that lactic acid bacteria isolated from the digestive tract of chickens had antibacterial effects against Salmonella, Escherichia coli and Clostridium bacteria (Poultry J. Microbiol. 2005; 54 (4) 287-294). Belfiore et al. Reported that the growth of Escherichia coli was inhibited by bacteriocin, lactocin and nisin, which are antimicrobial peptides produced by lactic acid bacteria in the culture of lactic acid bacteria (Food microbiol, 2007 May; 24 (3)). 223-229), Stern NJ et al. Reported that bacteriocin, an antimicrobial peptide produced by Lactobacillus salivarius, significantly inhibited Clostridium bacteria (Antimicrob. Agents chemother., 2006 Sep; 50 (9) 3111-3116).

Recently, the problem of resistance due to misuse and abuse of antibiotics and antimicrobial agents and the problem of residues in livestock products due to the addition of antibiotic feed have led to trade friction between countries. According to the 2005 Food and Drug Administration data, food and livestock products are shocking to find antibiotic resistance in more than 80% of E. coli and enterococci. In order to prevent antibiotic and antimicrobial residues in livestock and food products, the US Code of Federal Regulation has created a Food Additive Compendium for antibiotics and antimicrobials and strictly restricts their use. The Annex I of council regulation strictly controls the use of antibiotics and antibiotics by species. In Korea, in accordance with the criteria for the use of veterinary medicine for formulated feed under Article 72 of the Pharmaceutical Affairs Act and Article 46 of the Handling Rules of Animal Medicine, the use of feed additive antibiotics was reduced from 53 to 25 in July 2005. Regulates the use of materials. In addition, the Ministry of Agriculture and Forestry announced comprehensive measures for the hygiene and stability of livestock products and measures to reduce the use of antimicrobial substances, including antibiotics, to support the development and supply of antibiotic substitutes such as probiotics, enzymes, organic acids, medicinal plant preparations, and natural ingredients. Probiotics make up the bulk of antibiotics used. However, because probiotics differ from the test tubes of animals, there is a problem that the evidence indicating permanent settling in the intestine is unclear and should be continuously administered if a continuous effect is needed (Fuller, 1992, Livestock Research Vol. 46, No. 1). , 44).

In addition, depending on the environmental conditions, the expected effect is insufficient and there is a problem in stability (stability), so the processing process of the distribution process or feed, especially in the case of heat-treated feed such as pellet feed, crumble feed and flake feed during the manufacturing process The high heat and steam of 120 lead to the loss of viability and deterioration of vitality (Lee, In-Ho, Technology Management Approach to Direct-fed Microbials Theory, 2000, 17-19). Republic of Korea Patent No. 10-0261352 (Clean feed additive composition and its manufacturing method), 10-0396022 (Manufacturing method for livestock probiotics and livestock probiotics), 10-0489859 (Lactobacillus for treating and preventing poultry typhoid and poultry using the same Typhoid treatment method), 10-0688441 (feed additive using citrus gourd and its manufacturing method) and US Patent No. 6,503,544 (Animal feed additive) are all patents related to animal feed additives using lactic acid bacteria, and are fundamentally stable. I have a problem with In order to solve the problem of stability of heat of probiotics, a lactic acid bacterium that has been treated with tyldallization has been developed and marketed. J. Fourniat et al. Found that mortality was significantly reduced by oral administration of Lactobacillus acidophilus treated with E. coli (Swiss OF1). It was reported that the antimicrobial peptides produced by lactic acid bacteria were greatly increased during the heat treatment (Microecology and therapy, Vol. 14, 1984, 263-264). Currently, commercially available tindal lactobacillus is listed as the Lactobacillus asidophilus tindal freeze-dried product in the 2nd Amendment of Standards and Test Methods of the Korea Food and Drug Administration. It is difficult to feed chickens, pigs and cows, which are expensive to use when applied to economical animals, and there is a disadvantage that the antimicrobial effect is insufficient as an antibiotic substitute.

An object of the present invention is to repeat the process of culturing the conventional lactic acid bacteria in order to solve the above problems for a certain period of time after the heat treatment by the addition of betaine (betaine) and adding the yucca extract (yucca extract) twice After the sterilization process by adsorbing to a suitable adsorbent and then mixed with an excipient, to provide a lactic acid bacteria agent and a method for producing the enhanced antibacterial effect.

In the present invention, after incubating the conventional lactic acid bacteria at 34 ℃ to 37 ℃ for 6 to 12 hours and then heat treatment at 60 ℃ to 70 ℃ 10 minutes to 30 minutes by adding 0.005 to 0.2 parts by weight of betaine to 1 part by weight of the culture medium Lower to 34 ° C. to 37 ° C., add 0.001 to 0.05 part by weight of yucca extract per 1 part by weight of the culture, and incubate at 34 ° C. to 37 ° C. for a period of time, and then regenerate 0.005 to 0.2 parts by weight of betaine per 1 part by weight of the culture. Heat-treated at 70 ° C. to 80 ° C. for 10 minutes to 30 minutes, and then lowered to 34 ° C. to 37 ° C., and then, 0.001 to 0.05 parts by weight of yucca extract was added to 1 part by weight of the culture solution, followed by incubation at 34 ° C. to 37 ° C. for a predetermined time. Next, the adsorbent was adsorbed to 4 to 9 parts by weight of the adsorbent based on 1 part by weight of the sterilized lactic acid bacteria culture medium sterilized at 121 ° C. for 15 minutes to 30 minutes, and then 1 part to the adsorbate of the sterilized lactic acid bacteria culture solution. The present invention relates to conventional excipients 4 to 19 parts by weight of the lactic acid feed preparation for the addition to the composition enhanced the antimicrobial effect mixing and a method of manufacturing the same.

As described above, the lactic acid bacteria were incubated for a predetermined time, followed by heat treatment with the addition of betaine, followed by re-cultivation with the addition of the yucca extract, followed by sterile treatment, adsorption and mixing with the adsorbent and the excipient to feed the lactic acid bacteria. By preparing the formulation, it is possible to achieve stability problems against heat with enhancement of the antimicrobial effect.

Hereinafter, the present invention will be described in detail.

The present invention largely comprises (a) the heat treatment step and (b) the adsorption and mixing step of the culture solution is completed the heat treatment.

The heat treatment step of step (a) can be carried out divided into three steps,

As a first step, conventional lactic acid bacteria (Lactobacillus acidophilus, L.brevis, L.casei, L.fermentum, L.lactis, L.plantarum, L.bulgaricus, L.reuteri, etc.) approved by the US National Feed Ingredients Association After 6 to 12 hours of incubation at 34 ° C. to 37 ° C. using a culture medium, betaine was added thereto, followed by heat treatment at 60 ° C. to 70 ° C. for 10 to 30 minutes.

At this time, betaine used in the present invention is a kind of alkaloids extracted from sugar beet or sugar cane, and acts as an osmolyte to protect the lactic acid bacteria during heat treatment and activate the vitality of the lactic acid bacteria in the subsequent culture. Therefore, by adding a certain amount of betaine during heat treatment, it is estimated that the antimicrobial effect of the antimicrobial peptide material is increased by lactic acid bacteria, thereby enhancing the antimicrobial effect. The amount of the bitine added is preferably about 0.005 to 0.2 parts by weight with respect to 1 part by weight of the culture medium, when less than 0.005 parts by weight can not fully exert the effect of the lactic acid bacteria as an osmotic pressure protection agent during heat treatment, if exceeding 0.2 parts by weight Overuse is undesirable.

 In the second step, the appropriate amount of yucca extract was added to the culture solution, which was heat-treated as in the first step, incubated again for 6 to 12 hours at 34 ° C. to 37 ° C., and then, again, betaine was added, and this time at 70 ° C. to 80 ° C. Heat-treat for 10-30 minutes. Yucca extract (yucca extract) used in the present invention is a natural substance extracted from a plant called Yucca schidigera, which mainly lives in the Americas, and should contain at least 5% of sarsaponin. Yucca extract is used for animal odor removal, animal growth promotion, meat quality improvement and feed efficiency improvement in the livestock field, and in the present invention, it was used to prevent the aggregation of cells during heat treatment and to promote the growth of surviving lactic acid bacteria. The amount of the yucca extract is preferably about 0.001 to 0.05 parts by weight with respect to 1 part by weight of the culture medium, when less than 0.001 parts by weight is insufficient to prevent the aggregation of lactic acid bacteria, and when exceeding 0.05 parts by weight is preferred by excessive use. I can't. The amount of bitine added is preferably 0.005 to 0.2 parts by weight based on 1 part by weight of the culture as in the first step.

As a third step, add the appropriate amount of Yucca extract to the culture solution after the second heat treatment as in the second step, incubated for 6 to 12 hours at 34 ℃ to 37 ℃ and sterilized for 15 minutes to 30 minutes at 121 ℃ (a Prepare the sterile lactic acid bacteria culture medium, which is the final product of step). The amount of the yucca extract is preferably 0.001 to 0.05 parts by weight based on 1 part by weight of the culture as described in the paragraph.

The step (b) adsorption and mixing can be carried out divided into two stages,

As the first step, the bactericidal lactic acid culture medium obtained in the third step (a) is adsorbed while being sprayed onto a common adsorbent (for example, zeolite, silicon dioxide, methyl cellulose, etc.). The amount of the adsorbent is preferably about 4 to 9 parts by weight based on 1 part by weight of the bactericidal lactic acid bacteria culture medium. When the amount of the adsorbent is less than 4 parts by weight, the moisture content is high, and when the amount of the adsorbent exceeds 9 parts by weight, the amount of the adsorbent is required. Many are not desirable.

In the second step, the adsorbed sterilized lactic acid culture medium obtained in the first step and the usual excipients (e.g. chaff powder, powder, starch, lactose, etc.) were added to the mixer and stirred at 35 RPM for 10 to 20 minutes. Lactobacillus preparations can be prepared for enhanced antimicrobial effect. The amount of the excipient added is preferably about 4 to 19 parts by weight based on 1 part by weight of the bactericidal lactic acid bacteria adsorbate. When the amount of the excipient is less than 4 parts by weight, the amount of the excipient added to the feed may cause problems in mixing. If it exceeds the weight part, it is not preferable because the amount used when added to the feed may cause inconvenience when mixing.

Hereinafter, the present invention will be described in more detail based on Examples and Comparative Examples, but the present invention is not limited thereto.
