Abstract

We evaluated the physicochemical properties of four varieties of muskmelons (Thankyou, Beauty, Picnic, Sympony) during storage at $7^{\circ}C$. We stored Thankyou, Sympony, and Beauty varieties for 28 days at $7^{\circ}C$, while the Picnic variety was stored for 21 days. After the storage period, the mineral content of the Thankyou variety changed the least, by 2.36%, while that of the Sympony and Picnic varieties changed the most. The Thankyou variety also lost the least amount of free sugar content during storage. The Sympony variety had the highest vitamin C content at the beginning of the storage (26.0 mg%/100 g). After 14 days of storage, there was little difference in the vitamin C content of the varieties, which ranged from 11.5 to 12.5 mg%/100 g. The Picnic variety, which had the highest respiratory quotient, indicated lower storability than the other varieties. In a sensory evaluation, the Thankyou variety was considered to be the best in terms of consumer preference. However, the stem water loss seen in this variety tends to be the first thing that consumers see and may determine its merchantable quality.

국내산 머스크멜론의 품종(Thankyou, Beauty, Picnic과 Sympony) 차이에 따른 $7^{\circ}C$ 저장 중 품질 변화를 조사하였다. Thankyou, Beauty, Sympony 품종은 28일, Picnic 품종은 21일까지 저장 실험이 가능하였다. 저장 초기 무기질 함량이 308.6 mg%이었던 Thankyou 품종의 경우에는 저장중 함량이 약 2.36%만 감소하였던 반면, Sympony와 Picnic 품종은 각각 28.53, 26.35%의 큰 감소를 보였다. 또한 초기 유리당 함량이 높았던 품종은 Thankyou와 Picnic 품종으로 13.3%이었으며, 다음으로 Sympony(9.8%), Beauty(8.0%)순이었으며, Thankyou 품종은 저장 28일후에도 12.8%의 가장 높은 유리당 함량을 유지하였다. Vitamin C 함량은 Sympony 품종이 26.0 mg/100 g으로 가장 높았으며, Picnic (21.36 mg), Beauty(20.53 mg), Thankyou(16.89 mg) 품종 순이었지만, 저장 14일 이후에는 11.5~12.5 mg%으로 품종간의 차이를 보이지 않았다. 호흡률은 저장 중 변화가 가장 크게 나타났던 Picnic 품종이 다른 품종들에 비하여 저장성이 떨어졌다. 관능검사에서도 Thankyou 품종의 기호도가 가장 뛰어났지만 꼭지의 수분손실은 저장 중 다른 품종들에 비하여 큰 것으로 나타남에 따라, Thankyou 품종의 머스크멜론 유통 시 꼭지 수분손실을 최소화할 수 있는 추가 연구가 필요하다.
