Abstract

This study investigates the quality of strawberry jam containing different quantities of strawberry. Strawberry jam was prepared by the addition of 70-30%(w/w) strawberry puree, Sweetness, pH, total acidity, color, anthocyanin and pectin content, texture, free sugar, and organic acid content of the samples were measured. Decrease in the quantity of the strawberry puree led to a decrease in the following: total acidity(significance value p<0.05), anthocyanin, pectin, total free sugar, frutose, glucose, sucrose, and, organic acid content, namely oxalic acid, citric acid, malic acid, succinic acid, and formic acid. A texture profile analysis showed reduction in the hardness, gumminess, and chewiness of the jam. At the same time, decrease in the puree quantity also led to an increase in the sweetness, pH, L-value, a-value and b-value(significance value p<0.05) of the jam. These results promote, the consumption of fruit that are high in fruit, low in sugar, and do not contain any chemical additives.

딸기 과실과 설탕 이외에 젤리화 형성에 영향을 주는 산, 펙틴 등을 따로 첨가하지 않고 딸기와 설탕의 배합비를 달리한 잼의 품질특성을 조사하였다. 딸기를 70~30% 수준으로 감소한 처리구의 당도는 $59.00{\sim}77.33^{\circ}Brix$, pH는 4.17~4.28으로 증가한 반면, 총산도는 1.55~0.31%로 감소하였다. 딸기 함량이 줄어드는 S1~S5 처리구의 L값은 5.36~30.83, a값은 27.83~37.19, 그리고 b값은 9.08~40.52로 모두 증가하였다. 딸기 함량이 줄어들수록 딸기잼의 안토시아닌 함량과 펙틴 함량은 각각 9.91~5.15 mg/g, 4.86~1.46 mg/g으로 감소하였다. 딸기 첨가량에 따른 딸기잼의 물성 측정 결과에서도 hardenss, gumminess 및 chewiness은 딸기 함량이 줄어들수록 감소하였다. 딸기 첨가 수준이 낮아지는 S1~S5 처리구의 glucose, fructose 함량이 감소된 반면 sucrose 함량은 증가하였다. 유기산 구성은 oxalic aicd, citric acid, malic acid, succinic acid 및 formic acid으로 조성되었고, 이들 함량 변화는 딸기 첨가 수준이 낮아질수록 감소하였다. 따라서 본 연구를 통하여 산과 펙틴 등의 첨가물 없이 딸기와 설탕으로만 잼 제조가 가능하지만 색, 맛 등의 품질에 차이가 있음을 확인하였다. 통상적인 과실잼은 과실과 설탕을 동량인 50%(w/w) 수준으로 제조하고 있으나 과실을 60~70%(w/w) 수준으로 높인 고품질 딸기잼은 당도, 유리당, 유기산 및 안토시아닌 함량 등의 품질이 좋았다. 하지만 당도 $65^{\circ}Brix$ 이하인 점을 고려하여 저장안정성 연구, 안토시아닌 색소 안정성에 대한 연구가 추가적으로 추진되어야 할 필요가 있다.
