삼나물-페퍼민트 혼합물의 첨가 농도가 물속 콩기름 에멀션의 소비자 기호도와 지방질 산화안정성에 미치는 영향

Abstract

Purpose: Consumer acceptance and lipid oxidative stability of soybean oil-in-water emulsions with added samnamul (Aruncus dioicus)-peppermint (Mentha × piperita) mixture were investigated. Methods: The emulsions basically consisted of refined, bleached, and deodorized soybean oil (40 g) and citrate buffer (60 g, pH 4.0) with samnamul-peppermint extract mixture (1:1, w/w) added at 0, 400, 800, or 1,200 mg/kg that were stored at 25°C under light (2,600 lux) for 4 days. Consumer acceptance of color, taste, smell, mouthfeel, and overall liking of emulsions was evaluated with 100 panels, and lipid oxidation was evaluated based on the peroxide and p-anisidine values. Results: Consumer acceptance of the color, taste, mouthfeel, and overall liking of the emulsion improved in response to addition of the samnamul-peppermint extract mixture; however, there was no significant difference in acceptance among emulsions amended with 400, 800, and 1,200 mg/kg (p>0.05). The degree of lipid oxidation was higher in emulsions containing the added samnamul-peppermint extract mixture, and there was an increasing tendency as the amount added increased. However, there was no significant effect (p>0.05) on the rates of lipid oxidation. Conclusion: The optimum level of samnamul-peppermint extract mixture for an oxidation-stable and consumer acceptable soybean oil-in-water emulsion was 400 to 800 mg/kg based on consumer acceptance and lipid oxidative stability.
