고로쇠수액의 채취적기인 3월에 채취한 수액과 후기인 4월에 채취한 수액의 이화학적 특성을 비교분석하고, 고로쇠 수액의 품질을 향상시키고자 한외여과 전후의 품질특성을 살펴보았다. 4월에 채취된 고로쇠수액이 3월에 채취된 수액보다 총균수 및 탁도가 높았지만, 한외여과 후 탁도는 비슷한 수준으로 감소하였고 미생물을 검출되지 않았다. 유기산, 총산, 유리당 및 총당 함량은 4월의 고로쇠수액이 3월 수액보다 약간 낮았지만, 조회분과 무기성분은 높은 함량을 나타내었다. 특히 칼슘은 3월과 4월에서 각각 129.40 및 166.38 mg/L로 4월이 높았다. 고로쇠나무 수액의 영양성분은 한외여과 후 약간의 감소를 나타내었지만 채취적기 이후(4월)에 채취되는 수액을 한외여과 할 경우 미생물제거 및 탁도 향상 등 품질을 향상시킬 수 있으며, 무기성분이 더 많이 함유되어 있기 때문에 영양적으로 우수할 것으로 판단되었다.
We investigated the effects of ultra filtration (UF) of Goroshoe (Acer mono Max.) sap collected in March and April. The total bacteria and turbidity of the sap collected in April were higher than in March. However, after UF, the turbidity decreased and bacteria were not detected. The total acidity and total sugar of the sap collected in April were lower than that collected in March. After UF, total acidity and total sugar decreased slightly in sap from both of the collection times. The crude ash and mineral content of the sap collected in April were higher than in March. In particular, the calcium and potassium content of the sap collected in April were 166.38 and 29.47 mg/L, respectively, which was much higher than in March. Again, after UF, the crude ash and mineral content were decreased in the sap from both collection times. We concluded that UF of Goroshoe sap increased its quality regardless of collection time.
