This study provided basic data for the commercialization of healthy functional beverages by examining the physicochemical characteristics, nutrient content, and microbiological safety of onion peel beverage. The total acid of onion peel beverage was 0.12 mg/g and the pH was 6.07. According to the storage period, the total acid decreased and the pH increased in all temperature ranges(25℃, 35℃, and 45℃). After 30 days of storage, it showed 0.06 mg/g in all temperature sections and maintained the pH 7 range. The total phenol content, which is a nutritional component of onion peel beverage, was 0.93 mg/g, flavonoid content was 0.25 mg/g, and quercetin content was 0.17 mg/g. The flavonoid content decreased according to the storage period, and in the case of storage temperature of 25℃, it contained 50% content up to 120 days of storage, but in the case of 35℃ and 45℃, it had a flavonoid content up to 90 days and 30 days, respectively. In the case of quercetin, a residual rate of about 50% was shown for 150 days of storage at 25℃ and 35℃. In the case of 45℃, it decreased to 35% at 30 days of storage. On the other hand, onion peel beverage maintained a viable cell count of less than 5 CFU/mL for 150 days of storage, and no coliform group was detected. As a result of analyzing the quality characteristics of onion peel beverage according to storage period, quality stability was confirmed in physicochemical characteristics and microbiological safety. Research on changes in biological activity according to low-temperature distribution or storage period is necessary.

As an attempt to develop new functional health beverage by using medicinal herb, green ginger(Zingiber officinale Roscoe), we investigated the effect of Zingiber officinale on blood pressure and regional cerebral blood flow (rCBF) of rats with Zingiber officinale extracts. Zingiber officinale extract increase rCBF significantly. The drink produced consisted of Zingiber officinale extract 1.825%, maltitol syrup 17.0%, citric aicd 0.06%, ascorbic acid 0.02%, stevioside 0.001%, ginger flavor 0.11% and water. Brix, pH and acidity of product were 13.7, 4.4 and 0.09, respectively. This drink had good score by the sensory evaluation. The above results showed that development of such functional beverage using Zingiber officinale can used as a functional material improving blood circulation in beverage industry.
