Abstract

This study was conducted to investigate the quality characteristics of functional 'sunsik' as the nutritionally balanced diet for the moderns. The major nutrient of nutritionally balanced 'sunsik' was carbohydrate, while contained lower contents of protein and lipid than general 'sunsik'. Sucrose was the major free sugar of nutritionally balanced 'sunsik', and major organic acids were malic, tartaric, oxalic and citric acid. Free amino acids were predominantly serine, arginine, alanine and glutamic acid. Linolenic acid $(12.52\%)$ was contained in the nutritionally balanced 'sunsik'. Ca, Mg, K, Na and Fe were found as major minerals. Antioxidant activity was about $29\%$ compared to BHA and BHT(200 ppm), and about $40\%$ of $\alpha-tocopherol$(400 ppm). Sensory evaluation of nutritional balanced 'sunsik' gained higher sensory score in color, cooked aroma, flavor, chewiness and overall acceptance, compared to the general 'sunsik'.

일반인의 식사대용이나 노약자의 영양공급용 기능성 영양균형선식을 제조하고 그의 품질특성을 조사하였다. 영양학적 성분은 탄수화물의 함량이 가장 높았으며, 단백질함량은 일반선식이 $21.96\%$로 영양균형선식의 $16.76\%$ 보다 상대적으로 높은 함량을 나타내었다. 주된 유리당으로 sucrose 함량은 영양균형선식이 226.91 mg/100 g으로 일반 선식 74.82 mg/100 g 보다 높은 함유량이었다. 주요 유기산으로는 malic acid의 경우는 일반선식과 영양균형선식에 각각 15.41 mg/100 g과 36.76 mg/100 g로 높은 함량이었다. 주요 유리아미노산으로 영양균형선식에는 serine이 180.31 mg/100 g으로 일반선식의 serine 함량보다 약 2배정도로 높았다. 주요지방산으로 Linoleic acid의 함량은 일반선식에 $38.16\%$와 영양균형선식에 $29.30\%$로 높은 함유량을 보였다. 주된 무기질로 P의 함량은 일반선식에는 641 mg/100 g으로 높은 함량이었으나 영양균형선식에서는 457.64 mg/100 g 함량 수준으로 낮았고, 또한 Ca함량은 일반선식에 290.08 mg/100 g과 영양균형선식에 234.78 mg/100 g로 높은 함량을 보였다. 항산화활성의 경우는 영양균형선식 개발제품은 BHA 200 ppm과 BHT 200 ppm에 비해 약$29\%$ 정도의 항산화력을, $\alpha-tocopherol$ 400 ppm에 비해 약 $40\%$ 정도의 항산화력을 가지는 것으로 나타났다. 관능평가에서는 영양균형선식이 외관적 색, 고소한 맛, 향미, 씹힘성 및 전체적인 기호도 등에서 높은 관능점수를 얻었다.
