This study is on the feasibility of use of glycoprotein as an alternative material for collagen peptide in various areas such as cosmetics and food etc. by extracting, isolating and refining glycoprotein from carrots, red ginseng extract residue, sesame and pine needles using protease and by analyzing general characteristics and measuring various bioactivities with scale collagen peptide and pig skin collagen peptide, which are kinds of collagen peptide in order to use glycoprotein as substitute for collagen peptide. The results of analysis of nutritional composition showed less protein content than that of collagen peptide, but it had carbohydrate which cannot be found in collagen peptide and had a similar pattern to nutritional composition of carrot glycoprotein being used now as an ingredient of cosmetics. In the analysis of constitutive amino acids, the ratio of contents of hydroxy proline and glycine, the characteristics of collagen peptide, appeared similar and the contents of glutamic acid and aspartic acid which are involved in glucose metabolism and lipid metabolism appeared high. The average molecular weight ranged from 800 to 2,400 from measurement, which showed the range of lower molecular weight than that of collagen peptide and calorie also showed lower. As a result of measurement of total polyphenol content and total flavonoid content, it showed that glycoprotein had more contents generally, and the effect of bioactivity of glycoprotein appeared generally higher than that of collagen peptide although different kinds of glycoprotein showed a little different DPPH radical scavenging ability, total antioxidant capacity by ABTS, ACE inhibitory activity and nitrite scavenging ability. And, from the measurement of inhibitory effect on lipid peroxidation, both glycoprotein and collagen peptide showed higher inhibitory effect on lipid peroxidation than BHA and Vitamin A, control groups. Consequently, it is considered that glycoprotein has nutritional and functional characteristics that can be applied to cosmetics materials, processed food and various industries alternating animal-derived collagen peptide.
