  • This study was to investigate consumer recognition of food safety and food additives. The results of this study are as follows: 1. When shopping for food, the food safety was rated as foremost concern for the respondents and the details checked most often were manufacture date, packing condition and axpiration date, respectively. When asked their opinion about harmful factors in relation to food safety, the most important consideration was food additives. The highest rating for credibility regarding the sources of information on food was given to scientists in university and institute, lowest one was given to food manufacturer. 2. Government regulation on the use of food additives was known to exist, but control of the uses of food additive was considered inadequate by 60% of the respondents. These results showed significant differences for age (p<0.05), for education level (p<.01) and for income (p<.05) respectively. 3. 47.9% of the respondents indicated that they were willing to purchase the additive free foods, although it was expensive. More than 70% made an effort to eat food with less food additive and were concerned about possible effects of food additives on health, showing significant differences for age (p<0.05), for education level (p<0.05) and for income (p<0.05). 4. Labeling for food additive found on food package was shown to be unsatisfactory, showing significant difference only for income (p<0.05) and more information about food was needed by over 91.3% of the respondents, showing significant difference for education level (p<0.05). 5. Although approximately 80% of the respondents were concerned about artificial preservative, artificial flavor, artificial color and artificial sweetener, the concern about artificial preservative was the highest. Primary causes that respondents felt fear toward food additives were the unknown harms and cancer, and primary sources that respondents got information on food were televison and radio, respectively. From these results, it was shown that consumer considered food safety important and they felt a great deal of concern about food additives.

  • Migration levels of plasticizers, di-n-butyl phthalate (DBP), benzyl-butyl phthalate (BBP), di-n-octyl phthalate(DNOP), di-iso-decyl phthalate (DIDP) and di-iso-nonyl phthalate (DINP), di-(2-ethylhexyl) adipate (DEHA), from 46 poly(vinyl chloride) (PVC) wrap films and 54 PVC gaskets into food simulants were determined using gas chromatography/mass spectrometry (GC/MS). The method was validated with limit of detection (LOD) of $0.01{\sim}0.02\;{\mu}g/mL$ for DBP, BBP, DNOP and DEHA, and $2\;{\mu}g/mL$ for DIDP and DINP. The linearity were found to be > 0.99 for all the compounds in concentration range of $0.1{\sim}81.4\;{\mu}g/mL$, and overall recoveries were ranged from 90.4 ~ 99.6%. DBP, BBP, DNOP, DEHA, DIDP and DINP were not detected in food simulants, except 1 wrap sample from which 0.28 and $0.99\;{\mu}g/mL$ of DEHA were detected respectively when tested with 20% ethanol and n-heptane as food simulants. These values were below the regulatory limitation in European Union (EU).

  • This study was conducted to investigate the quality characteristics of mungbean starch gels containing various hydrocolloids (carrageenan, locust bean gum and xanthan gum) during room temperature storage ($25^{\circ}C$ for 24, 48 and 72 hours). Carrageenan and xanthan gum reduced the pasting viscosity of mungbean starch, whereas the locust bean gum increased the viscosity. The melting characteristics, as assessed by DSC, showed that carrageenan and xanthan gum delayed gelatinization of mungbean starch and the locust bean gum had no effect on this property. The lightness (L) of the gels with the locust bean gum was similar to that without the additive during storage, whereas that with carrageenan and xanthan gum was higher than that without the additive. Hardness, chewiness and gumminess of the gels with the locust bean gum was higher than that without the additive during storage, whereas that with carrageenan and xanthan gum was lower than that without the additive. The rupture stress, rupture strain and rupture energy of the gels with carrageenan and xanthan gum was lower than that without the additive during storage, whereas that with the locust bean gum was similar to that without the additive. In the sensory evaluation, springiness and cohesiveness of the gels with carrageenan and xanthan gum were lower than those without the additive, whereas springiness, brittleness and hardness of the gels with the locust bean gum were higher than those without the additive. In addition, the overall acceptability of the gels with the locust bean gum improved. The above results showed that carrageenan and xanthan gum lowered the quality characteristics of the mungbean starch gel and the locust bean gum improved them. Thus, the addition of 0.5% locust bean gum is an appropriate method for improving the quality characteristics of mungbean starch gel.

  • This study evaluated effects of food additive nutrition education on food additives-related knowledge, subjective awareness, and perception and dietary behaviors of food label use and processed-food intake. The study subjects were 5th grade students attending an elementary school in Seoul. A total of 101 subjects were assigned to either education (N = 50) or control (N = 51) group, and 3 food additive nutrition education classes were implemented to the education group. Self-administered questionnaires were collected from all the participants twice, a week before and after the nutrition education to compare the changes between two groups. The food additives-related knowledge and subjective awareness significantly improved in the education group compared to the control group. The changes in perceived harmfulness and perceived necessity for taste were also detected significantly different between the two groups, with more positive changes in the education group. Dietary behaviors of checking food labels and trying to purchase processed-foods with less food additives improved in the education group at a significant level in comparison with the control group. Additionally changes in intake frequency of several processed-food items were significantly different between the groups, again in a more positive direction in the education group. The study findings showed short-term food-additive nutrition education including hands-on activities could positively modify elementary school children's food additives-related knowledge, perception, and certain dietary behaviors, stressing better settlement of in-class nutrition education within an elementary school's education curriculum.

  • 세균포자는 살균소독제에 대해 영양세포보다 수백~수천배이상 저항성을 가지고 있기 때문에 과산화수소 및 과산화초산을 원료로 하는 아포살균용 살균소독제는 Escherichia coli 및 Staphylococcus aureus의 감소율을 측정하는 현행 살균소독제 유효성 평가방법을 적용하기 어렵다. 따라서, 아포살균용 살균속독제의 유효성 평가를 위해 Bacillus subtilis ATCC 6633 포자를 표준균주로 하여 아포살균용 살균소독제를 처리했을 때 초기포자수를 $10^3$이상 감소시키는지를 측정하는 정량적 표준시험방법을 확립하였다. 확립된 시험법은 아포살균력을 측정하는 국가표준시험법으로서 아포살균용 살균소독제의 유효성 평가에 적합하였다.

  • When bread making, the condition of thawing-fermentation for frozen dough were tested in variable temperature, and measured thawing-fermentation time and volume of frozen dough. L-Ascorbic acid (L-Aa) was added in frozen dough for the comparison test of develop volume in bread staling degree of baking bread were measured additive frozen dough which was stoppages in freezing, staling degrees were tested hardness with Rheometer. The test for comparison of thawing-fermentation time in variable temperature was shown the condition of dough conditioner at 3$0^{\circ}C$ was most effective for bread making, Because That condition was required very short time(74 min) But, in this comparison of volume in final products was shown the products in the condition of thawing-fermentation at 3$0^{\circ}C$ was smaller than the products at 5$^{\circ}C$(418 ml). The baking volume of L-Aa additive frozen dough which has under gone thawing-fermentation at 3$0^{\circ}C$, were shown baking volume of 420 ml in 2 weeks storage terms to 100 mg/kg L-Aa additive dough and shown baking volume of 454 ml in 4 weeks storage terms to dough of 200 mg/kg additive weight. Staling degrees of L-Aa additive frozen bread were measured with Rheometer. The hardness of 100 mg/kg L-Aa additive frozen bread was sown low level hardness in 1~2 weeks freezing term, 150 mg/kg L-Aa additive frozen bread was shown low level hardness in 3 weeks freezing term. In 4 weeks freezing term, 200 mg/kg L-Aa additive frozen bread was shown low level hardness compared with non-additive L-Aa frozen bread. In comparison of frozen bread quality, non-additive L-Aa products was better than additive L-Aa products in equality of baking shape and external apparence. But in total quality in external and internal apparence, additive L-Aa products was better than non-additive L-Aa products.

  • This study was aimed to examine the quality characteristics of the bread with the muffin added with the by-product of fermented ethanol from wheat rye that has high $\beta$-glucan contents. In the muffin added with TEFB (Triticale Ethanol Fermentation By-product), the height of the muffin decreased as the additive contents increased. There was no significant difference among the volumes of the muffins added with TEFB 0%, 5%, 10% and 15%. In the muffin added with TEFB, the height of the muffin decreased as the additive contents increased. In the moisture measurement of TEFB muffin, the moisture contents increased as the TEFB additive contents increased. Using SEM, showed that as TEFB additive contents increased, gluten contents was relatively lowered, which led to the reduced gas retention power and generation of rough tissues. In chromaticity, as the TEFB additive contents increased, the brightness decreased and the redness and yellowness decreased as well. The result of texture measurement showed that as the TEFB additive contents increased, hardness increased. springiness decreased gradually as the TEFB additive contents increased. There was no significant difference in cohesiveness (p<0.005). Although there as signigicant difference between the control group and the additive group in gumminess (p<0.005), there was no significant difference for a certain amount of additive contents (p<0.05). While there was significant difference in chewiness between the control group and the additive group (p<0.05). there was no significant difference for a certain amount of additive contents (p<0.05). The result of taste test of TEFB added muffin showed that the preference for the muffins added with 5% or more TEFB decreased. This study found that more than 5% of TEFB additives to muffin decreases the preference level.
