TR TR TR DESCRIPTION METHOD OF OBTAINING COLLAGEN FROM EXTRACELLULAR MATRIX COMPONENTS Field to which the invention relates: It is related to the method of obtaining collagen, which can be used in the health, food, cosmetics and medical material sectors, from the extracellular matrix components in lamb's feet. State of the Art Regarding the Invention (Prior Art) Extracellular matrix (ESM), a complex that fills the spaces between cells and connects cells to each other, contains most proteins, hormones, proteoglycans and growth factors, and enables cells to interact with intracellular signaling pathways to perform special functions. and a dynamic structure ESM, called sclula connective tissue, is found in large amounts in cartilage and bone. Collagen is one of the basic extracellular matrix components that constitute an important part of ESM. Collagen properties vary depending on the raw material and extraction conditions. The most used extraction methods are based on the solubility of collagen in neutral salt solutions, acid solutions and acid solutions to which enzymes are added, which are classical extraction methods. Classical With the extraction method, it is seen that both the amount of solvent used and the extraction times are long. The functional properties of collagen vary depending on the processing conditions of the raw material from which it is obtained. Therefore, it is important to determine the appropriate conditions for the raw material in order to obtain high efficiency and the best collagen properties. In the known state of the technique, Acid hydrolysis or enzymatic hydrolysis methods are generally used in collagen extraction.Recent studies have shown that the use of ultrasound together with these methods is effective in increasing the extraction efficiency. Ultrasound technology plays an important role in achieving the goal of sustainable "green" chemistry. However, it has many advantages over other methods, such as being safe, cheap, reproducible and environmentally friendly. Studies using ultrasound in collagen extraction @malarrsîiîllîiîi This situation reveals the need for new studies to evaluate the effect of ultrasound on enzyme activity and the benefits of using it together with other methods. However, in the previous technique, extraction times and therefore energy consumption are quite high in the extraction with collagen extraction methods. Description Home Objectives 3 The present invention relates to a method of obtaining collage from the extracellular matrix components in lamb's feet, which meets the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages. The primary purpose of the invention: by developing an innovative and environmentally friendly method, by applying the ultrasound process after a 6-hour processing time, instead of the 24-hour or more applications used in traditional extraction methods, the time to obtain collagen is shortened. It is the production of collagen with high purity, eta and added value. Ultrasound application is seen as an effective method to increase product purity and quality. Studies on collagen extraction have shown that ultrasound application preserves collagen adhesion and improves product properties. The invention extraction method includes ultrasound application in addition to acid and enzymatic hydrolysis methods. With the invention method, high value-added collagen production has been achieved from lamb feet, which is an animal by-product, in shorter extraction times with kgstone compared to the methods known in the art. Obtaining collagen, which is considered one of the most important biomaterials, by evaluating lamb feet is especially important for the meat industry in terms of atm evaluation. With the invention method, the effects of ultrasound on collage structure have been examined in detail. Since most commercial collagens are obtained from mammals, especially pigs, they are not preferred for religious purposes. In this context, halal collagen will be produced as an alternative to pig collagen by using lamb feet. The method of the invention is not suitable for using lamb's feet as a source of collagen. The invention method can also be used effectively for collagen raw materials of animal origin, such as cattle, sheep or poultry feet: tendons, skin or tracheas, chicken sternum or mountain fish skin, scales, fins or fish. Description of the Drawings Explaining the Invention: The drawings and related drawings necessary for a better understanding of the subject of the invention, the method of obtaining collagen from extracellular matrix components and the characteristic features of the obtained collagens are as follows.

The mentioned animal sourced collagen raw material is the feet of cattle, sheep or poultry: tendons, skin or trachea, chicken stem or fish skin. It may have scales, fins or wings. In the invention, lamb's foot was preferred as the raw material of the collage of animal origin. In order to effectively determine the pre-treatments to be made, component analyzes were carried out on lamb feet. Lamb's foot composition was taken into consideration when determining the pre-processing steps. Preliminary Processes: (1) Lamb feet: after being cleaned with a grinder to remove contaminants, they were ground in an industrial grinding machine for size reduction. (2) Cleaned and reduced-sized lamb feet were homogenized in 0.05 M Tris-HCl (pH 7.5) at a ratio of 1:20 (w/v) for 50 minutes using a waring blender. At the end of the process, the face was centrifuged at 9000 rpm for 25 minutes at 4°C. After centrifugation, take Elm Et 3. (3) After the centrifuge, the mixture was added for the purpose of oil removal at a ratio of 1:10 (w/v). It was treated with 50% ethanol for 3 hours. At the end of the process, the mixture was centrifuged at 9000 rpm for 20 minutes at 4°C and the solid fraction was collected. (4) The collected solid mixture was centrifuged with 0.5 M EDTA-ZNa for decalcification purposes. (5) Removal of non-collagenous proteins was carried out in 0.1 M NaOH at a ratio of 1:10 (W/v). It was kept for 1 night. Afterwards, centrifugation was applied for 25 minutes at 9000 rpm at 4°C and katEkßEh al Elm St E. (6) Pre-processed lamb feet were stored at -18°C until extraction. Solvents and their ratios used in the extraction stage and ultrasound conditions. It was determined as a result of many experiments. Three different temperatures, durations and durations were tried as ultrasound application; Production continued at the highest parameter, reflecting the highest collage density. Extraction step 3 (1) Samples after pre-treatments: ratio containing 01% pepsin (w/v) for extraction process Ilda with 5% lactic acid at 4°C for 6 hours 31: EJIn Wet E. ultrasonic bath (Bandelin Sonorex (3) At the end of the extraction process, the mixture was centrifuged at 9000 rpm at 4°C for 30 minutes. At the end of the centrifuge, silt was collected. 4) Alian sßlükßßi was treated with 2.5 M NaCl for 1 night in order to precipitate the proteins. (5) After the precipitation process, the final precipitate was collected by centrifuging for 30 minutes at 9000 rpm at 4°C. (6) Dialysis was carried out to remove excess salt. The samples were first dialyzed against 0.1 M lactic acid for 24 hours and then against pure water for 48 hours. (7) At the end of dialysis, the samples were lyophilized and stored at -18°C until analysis. reach their concentrations. Collagen density concentrations are given in Table 1. Table 1: Collagen concentration of samples obtained under different extraction conditions. Ekşiralßiyun Kusulu Kulajeii content (ug/uL) The extraction condition with the highest collagen concentration was determined as 25°C-60 min ultrasound application (5061.75 ug/ul). Likewise, an increase in collagen concentrations was observed due to increasing ultrasound time. However, in order to avoid structural deterioration, it should not exceed 60 minutes. It was observed that the collagen samples obtained at different ultrasound durations at 25°C had the highest collagen concentration. It was observed that the collagen concentration began to decrease at temperatures and times above 25°C. In general, it is seen that the ultrasound duration affects the collagen concentration more than the humidity. Collagen analysis results have shown that lambsfoot can be used as an alternative collagen source. SDS-PAGE bands showing protein distributions and subunit components of collagen samples are shown in Figure 3. In this figure, protein distributions of collagen samples can be seen. The fact that no other protein band not related to collagen was seen in the protein gel electrophoresis results shows that the sample is 90% pure. The a, [3 and y chains that make up collagen are shown in the figure. It has been observed that all collagens produced under different extraction conditions consist of (11, (12), B and y chains (~. Electrophoresis results show that all collagens produced under different extraction conditions maintain their structural integrity and that Type 1 collagen [al(1)]2 (120)] is the main component of lamb's foot collagen. FTIR spectra of the collagen samples obtained at different times and times are shown in Figures 4, 5 and 6. CH2 bending was observed in the amide A, amide B, amide 1 and amide ranges, which is characteristic in the FTIR spectra of all collagen samples. Amide III banded with "1450- The fact that the wave number E E density ratio between the bands of 1454 cm""" is close to 1 shows that the triple helix structure of the collagen is not damaged. This ratio was found to be 1.17 for all collagen samples. FTIR results showed that the ultrasound process applied at the difference in wetness and duration did not damage the collagen structure. The surface morphology and particle sizes of collagen samples were determined by scanning electron microscopy. SEM images were taken at a magnification of 5000). SEM images of collagen samples obtained under different extraction conditions are given in Figure 7. When the surface morphologies and microstructure of the collagen samples are examined, it is seen that all samples have fibrous and porous adhesives. The average fiber diameter of the collagen samples is 0.1. ~0.9 um spacing has been observed to vary. Some differences have been observed depending on the ultrasound temperature and duration. While a more regular and distinct fiber structure was observed in the collagen samples at 20°C, as the temperature increased, a more irregular, rough and spongy structure with small pores was observed. It is clearly seen that increasing ultrasound durations affect the collagen structure. The most optimal results were obtained at 20°C and 60 min extraction conditions, regardless of both the desired collagen mass (Figure 7: A3) and the concentration. The space between the intertwined layers gives porosity to the collagen. Fibers with a spiral-like appearance were observed as an interconnected layer, as reported in the art. Porosity, pore size and material surface area are considered important parameters of biomaterials for biomedical purposes.
