This research was attempted to investigate the sex bias in nutrition knowledge, food preference and food roles in the family. 152 couples living in Seoul, Cheonan in the 20s∼60s were selected for this research as subjects from October 1 to December 20, 1991. The data analysis was made by way of frequency, percentage, χ^2-test using SPSS package. The summarized results are as follows. 1. The survey on the sex bias in nutrition knowledge related heart disease on the subjects showed that there were no significant differences between men and women. But women had a relatively good nutrition knowledge than men. Especially women had a good nutrition knowledge that low sodium diet and exercise are efficient on preventing heart disease. 2. On the food preference, the subject showed significant difference between men and women. Men showed a relatively highest preference for protein food just as pork, fish, and tofu. Women showed a relatively highest preference for bread, fruit and vegetable. 3. On the food roles, the subjects showed that gender difference in household labor regarding food preparation still exit. Food-related activities are clearly still the domain of women in most families. Husbands and wives in younger families tended to think the husbands showed increase their efforts in food related activities.

The objective of this study was to improved the limited functional characteristics of mungbean whole` globulin. The mungbean whole globulin was acylated with succinic and acetic anhydride, and the functional properties of acylated protein were investigated. The results obtained were as follows : 1. The UV-absorption spectra of acylated whole globulins with that of the succinylated 74% whole globulin as large blue shift of the absorption maximum and minimum wavelength from 275㎚ to 269㎚, respectively. 2. The mobility of acylated whole globulin were increased on PAGE pattern, and degree of mobility was particulary remarkable in case of succinylation. 3. The water absorption capacity of whole globulin was increased by acylation. The most increased rate of whole globulin was 174.02% from succinylated 74%. The oil absorption capacity of whole globulin was increased by acylation. The most increased rate of whole globulin was 165.41% from acetylated 81.77%. 4. The bulk density of whole globulin was decreased by acylation, and the greater the extent of acylation, the smaller the bulk density. 5. The foaming capacity and stability of whole globulin was increased by acylation, and remarkably high in 74% succinylated whole globulin, in contrast, however, the foaming capacity and stability of native and acylated whole globulin were decreased by heat treatment.
