LOHAS(Lifestyles Of Health And Sustainability) drinks were prepared by the addition of mulberry leaf powder(MLP) at various levels(0%, 5%, 10% and 20%). Their characteristics of the drinks were examined according to antioxidant activity and sensory evaluation. In the sensory evaluation, there was no significant difference between the control group(0% MLP group) and 5% MLP group for overall quality. For the proximate compositions of the LOHAS drinks, moisture, crude ash, crude protein and crude fat were all increased as the ratio of MLP increased. For the mineral contents, the amounts of calcium and magnesium were increased, but sodium, according to adding levels of MLP.

It has been known that the mulberry leaf is effective in many diseases. Nowadays, the pharmacological effects on diabetes mellitus of mulberry leaves have been confirmed and they are used for many aspects. And Mulberry leaves are also hewn to be effective in the prevention of diabetics, because of their rich amino acids and fibers. From the results of sensory evaluation, the addition of up to $0.5\%$ MLP(mulberry leaf patty), to the chicken patties induced no significant differences in texture, appearance, and color until $0.5\%$ adding of MLP. However, chicken patties with added $0\%$, and $0.25\%$ added of MLP were shown have the highest acceptability, so these levels were thought to be the proper addition amounts of MLP to the chicken patty. Brightness(L) of these patties was the highest in the $0\%$ group as (55.63) and decreased with increasing adding amount of MLP level. Redness(a) was decreased with increasing adding amount of MLP and appeared as ueenish. Yellowness(b) was the lowest in the $0\%$ MLP addition group as (13.31) and increased with increasing MLP level. Hardness was the highest in the chicken patty with $0.25\%$ added MLP, and the lowest value in the chicken patty with $0.5\%$ added MLP. Cohesiveness was the highest in $0\%$ added MLP added chicken patty and springiness was the highest in $0.5\%$ added MLP added chicken patty. But not significantly. Also Brittleness was similar among the various chicken patties with no significantly difference. As for the composition of fatty acids in the chicken patties with added MLP, saturated fatty acids were decreased and unsaturated fatty acids were increased with increasing MLP Especially, the contents of essential fatty acids showed a largely increasing tendency in the chicken patties with added MLP Linoleic acid, linolenic acid, and arachidonic acid were increased to $9.38mg\%,\;0.65mg\%\;and\;1.28mg\%$, respectively in chicken patty with $1.0\%$ added MLP.

Recently, the concern about safety and functional substances of foods are increased therefore antioxidant substances and plants which had pharmacological effect have been studied actively. It has been known that the mulberry leaf is effective in curing many diseases. Nowaday, the pharmachological effects of mulberry leaves on diabetes mellitus and their usage for many aspects were confirmed. Mulberry leaves are known for effective in prevention of diabetes mellitus, because of specific amino acids and fibers. In this study, methanol, hexane, chlorform, ethyl acetate, and butanol extracts obtained from mulberry leaves were added to soybean oil and they were stored for 30 days at $60{\pm}2^{\circ}C$ and peroxide value(POV) and conjugated diene value(CDV) were measured periodically. Results of this study were obtained as follows; 1. The POV of soybean oil after the addition of each mulberry leaves powder(MLP) extracts generally enhanced as the storage time was prolonged, so the POV of all samples was reached higher than 100meq./kg.oil after 10 days storage without the addition of butanol, methanol, ethylacetate, hexane extracts at 0.1% level. Especially, the POV of soybean oils including butanol extract was 87.35meq/kg.oil after 10 days storage and antioxidant activity of butanol extract was shown to be superior to that of BHT. The pattern of the changes of the CDV of soybean oil after the addition of MLP extracts at 0.02%, 0.05% and 0.1%, respectively, were almost constant during 10 days of storage and then rapidly increased during the rest of experimental periods. During 10 days of storage in case of 0.1% adding level, the antioxidant activities of the butanol extract was superior to that of the each MLP extracts.
