칼슘함량이 높은 녹미채를 넣은 김치를 만들고 1$0^{\circ}C$에서 숙성하면서 pH, 적정산도, 환원당, 총균수, 유산균수 및 관능 검사를 실시한 결과는 다음과 같았다. 녹미채의 첨가량이 많을수록 pH가 높은 것은 김치의 숙성 5일에서 15일 사이였으며, 그 이후로는 시험구간에 차이가 크지 않았다. 녹미채를 첨가한 김치의 적정산도는 대조구보다 낮았으며, 0.1%를 첨가한 시험구가 가장 낮은 값을 보였다. 김치의 적숙기로 생각하는 적정산도 0.6~0.8%를 기준으로 본다면 0.1% 첨가구는 2~3일 정도 적숙기를 연장하는 효과가 있을 것이다. 또한 이 시험구는 숙성 10일부터 다른 시험구에 비하여 높은 환원당 함량을 유지하였는데, 이는 적정산도의 증가가 다른 시험구에 비하여 낮았기 때문으로 보인다. 김치를 담근 직후부터 숙성 2일째까지 녹미채를 첨가한 김치의 유산균수가 대조구에 비하여 현저히 낮았으나 10일 이후에는 큰 차이를 보이지는 않았다. 숙성 5일째인 김치의 색, 냄새 및 맛을 평가한 결과 대조구가 가장 높은 점수를 얻었으며, 녹미채를 0.1% 첨가한 시험구는 대조구보다 점수는 낮았으나 유의적인 차이는 없었다.

The effects of sugars and heating methods on the sugar infilteration, hardness, color and organoleptic characteristics were investigated for quality improvement of sugared chestnuts. Among the tested sugars, isomaltooligosugar was the most effective on the rate of sugar infilteration. High temperature increased the rate of sugar infilteration during sugaring process, but color and flavor were deteriorated at 9$0^{\circ}C$. The most suitable temperature for sugaring process was 7$0^{\circ}C$. The product sugared with fructooligosugar recoreded the highest score in hardness, odor and preference than any other sugars tested and increased the rate of sugar infilteration when mixed with sugar at same amount. The changes of soluble solids in chestnuts boiled with microwave oven were ranged from 18。Brix to 32。Brix, while chestnuts heated in general were from 18。Brix to 28。Brix. Chestnuts boiled with microwave heating were sugared rapidly. The hardness of boiled and sugared chestnuts was lower when treated with microwave than with general heating. Hunter's L and b value of sugared chestnut treated with microwave decreased during processing but a value somewhat increased.

Physicochemical changes were determined for the boiled-dried anchovies packaged in a laminated film(nylon 15${\mu}{\textrm}{m}$/polyethylene 100${\mu}{\textrm}{m}$) and stored for one year at ambient and cooling(5~1$0^{\circ}C$) temperatures after gamma irradiation. Lipophilic and hydrophilic browning pigments increased with storage time particularly at ambient temperature, even though initial 5 kGy irradiation did not affect the formation of pigments significantly. This results were confirmed by the instrumental color determinations, Hunter color L, a, b and ΔE. With respect to changes in relative fatty acid compositions, storage period and temperature were more influential factors than gamma irradiation. Irradiation at 5 kGy induced insignificant changes in the total flavor profiles of stored anchovies, which were mainly composed of n-dodecanal(26.7%), n-pentadecane(22.2%), n-octanal(4.9%) and 2-pentylfuran(3.4%).

This study was carried out to investigate the anti-fungal effect of Pyrethri Flos Boiled Solution (PFBS) from Chrysanthemum Cinerariaefolium Visiani on Microsporum canis, Microsporum gypseum and Trichophyton Mentagrophytes with 0.5 ml, 1ml, 2 ml. In comparative drugs, on Sabouraud's glucose agar medium to 2 ml respectively and PFBS on the rabbit skin lesions, in vivo experiments, were observed. The results obtained were as follows : PFBS slightly suppresed the growth of the fungi in 0.5 ml and markedly it in 1 ml and 2 ml. In comparative drugs, benzylbenzoate represented similar anti-fungal action in 2 ml compared with PFBS. While, salicylic acid and boric acid represented less suppression of growth of the fungi than PFBS in 0.5 ml. The effects of PFBS on the rabbit skin lesions inoculation with dermatophytes was almost normally recorved about Microsporum gypseum, Trichophyton mentagrophytes except Microsporum canis after 8 days.

To explore the possibility of using freeze dried loach for instant choo o tang(Korean traditional loach soup), protein qualities and fatty acid composition were evaluated on boiled and steamed loach. Total lipid and ash content were lowered in both heated(boiled and steamed) loaches due to deboning and eviscerating during cooked meat preparation. Profiles of total amino acids were not changed seriously by the type of cooking, but the amount of essential amino acids were comparable in all samples. Two times more free amino acids were quantified in cooked samples compared to raw meat. Available lysine was marginally decreased by cooking, and that caused some measurable change in typsin indigestible substrate(TI) in streamed whole loach. In vitro protein digestibility of the heated loaches was not altered drastically and the protein quality determined as computed protein efficiency ratio(C PER) was similar for the raw, boiled and steamed loach. The ratios of unsaturated to saturated fatty acids changed measurably in heated whole loach. The results shows that heating caused apparent oxidative deterioration of the polyunsaturated fatty acids.

To compare the cooking methods (boling, steaming) for broccoli, the extracts from water or 80% ethanol were used to determine total polyphenols, total flavonoids, and antioxidant activities. The total polyphenol and flavonoid contents of both fresh and boiled or steamed broccoli were found to be higher in the 80% ethanol extract compared to the water extract. Nine glucosinolates were identified in broccoli using high-performance liquid chromatography. The glucosinolate content was found to be higher in steamed broccoli compared to fresh broccoli; however, in boiled broccoli, the glucosinolate content decreased by 5.74-18.64% compared with fresh broccoli. It was confirmed that antioxidant activity decreased through heat treatment such as boiling or steaming compared to unheated broccoli. In particular, the decrease in antioxidant activity was higher in boiled broccoli than in steamed broccoli. The results suggested that it would be preferable to use raw or steamed broccoli rather than boiling it in water to minimize the loss of bioactive substances when consuming broccoli.
