Mayonnaise has probability of fatness and adult disease because main components of it contain high calorie. We prepared dietary mayonnaise used for corn starch paste. And also, dietary mayonnaise with hot taste was manufactured by using both O.R.capsicum and O.R.paprika. It was observed that the calorie of general mayonnaise was 748 Kcal and the calorie of dietary mayonnaise used for starch was 237∼240 Kcal. The dietary effect was certified by animal experiment.

We have examined the effects of mayonnaise on the lipid metabolism and calcium bioavailability of rats by using myonnaise. Sprague Dawley male rats(131$\pm$5g) were divided into four dietary groups[Control (Con, 10% soybean oil), Mayonnaise(M5), 10% Mayonnaise(M10)and 15% Mayonnaise(M15)] were fed ad libitum with experimental diets for four weeks. Final body weight exhibited a decrease in the M10 group, also final thymus organ weight showed a significant decreasing trend(p<0.05). The levels of serum, liver and adipose total lipid were significantly different among the four experimental groups(p<0.05). Serum calcium levels were significantly lower in the M15 group than in among the groups(p<0.05). On the other hand, the elevation of serum cholesterol levels were not clearly observed, but triglyceride levels were elevated the M5 and M15 group. The P/S ratio of adipose tissue were higher in the M10 group(2.35$\pm$0.35) than any other groups. Free EDTA in mayonnaise was 0.0307~0.0387%, moisture 12.46~16.49% and calcium 0.012~0.019%. But commercial mayonnaise contained free EDTA higher than the safe use (0.0075%). Safety problems of EDTA additives resulted from mass processed mayonnaise are arising. Though the evaluation of safety can not reach a conclusion with only one or two clinical case studies. It often simply jumps to conclusion. Therefore more wide ranged discussion and deepened study is required to search for the solution of safety problems.

The study was carried out to investigate housewive's consumption pattern and preference of mayonnaise for the development of egg-white mayonnaise. Data was collected from 515 housewives in Ulsan by self-administered questionnaire. The collected data were analyzed by SPSS package program. The results were as follows: 1. Most(98.1%) of housewives were concerned about nutrition and health and they considered that nutrition was the most important factor when purchasing food related items. 2. The frequency of using processed foods was two to three times a week and the reason for use it was the convenience. Usually the housewives obtained nutrition related information through mass media such as TV, radio(37.5%) , and newspaper, magazine(32.1%). 3. 75.9% of the subjects thought mayonnaise is a high calorie food and 57.5% of them knew the basic ingredients of mayonnaise. Most(79.3% ) of housewives perceived that cholesterol which is rich in egg yolk is related to cardiovascular disease and arteriosclerosis. Among family members, children showed high degree in the preference for mayonnaise. 4. Comparison of the low cholesterol mayonnaise which was made by egg white for egg yolk with commercial product was made by sensory evaluation and mechanical test. The viscosity and turbidity did not show any difference. Overall taste of low cholesterol mayonnaise was better than of commercial product. Based on these results of this study provided useful information for development of egg-white mayonnaise (low-cholesterol mayonnaise) and expected the possibility of using low cholesterol mayonnaise will be high.

The purpose of this study was to investigate the sensory and mechanical characteristics of mayonnaise containing various levels of green tea powder The highest viscosity of mayonnaise was obtained at the green tea powder concentration of 0.5% The emulsion, stability was increased with the addition of green tea powder. In the sensory evaluation, overall acceptabilty appeared to be the highest when 0.1% of green tea powder was added. There was a significant difference between the samples (P<.05) In terms of change in color, the values of L, a, b, and ΔE decreased as the amount of green tea powder increased. In the measurement of the texture, the hardness of mayonnaise was highest in the control of green tea powder, and the springiness appeared to be higher in the mayonnaise with 0.1% of green tea powder. The odor acceptabilty in the sensory evaluation showed a negative correlation with the values of gumminess in the mechanical characteristics. The subjective parameters that affect overall quality on sensory evaluation were determined by, and they were odor acceptabilty, after taste, oily taste, sour odor. sweet taste. egg odor, color acceptabilty, and salty taste. These results showed that mayonnaise made with 0.1% green tea powder, salad oil 474.5ml. egg golk 85g, sugar l0g, salt 7g, and vinegar 23m1 with the addition of 0.6g green tea powder was the most effective compared with other treatments.

This study was conducted to evaluate the consumers' preferences and perceptions on the salad and its dressings, via a total of 401 subjects in the Taegu area on the basis of 5-point Likert scale. Anthropometric data included the total subjects consisted of 66 females and 335 males: categorized by age, 20's (103), 30's (135). 40's (83), over 50's (80), The average size of family was 4.2 persons. According to BMI, 64.8% of the subjects belonged to the normal group. The age group that liked salad most was the 20's group, which was also the group that ate salad most frequently. The salad was perceived as food item which is convenient to eat(3.83), healthy(3.63), easy to prepare(3.73) and delicious(3.61) but rarely as a expensive item(2.44). The ingredients, used for salad preparation included fruits and vegetables(3.19) such as tomato and cucumber. Among the salad dressings, the fruit dressing was preferred the most(4.59), while the mayonnaise the least(3.59). The mayonnaise was perceived as an item with highest calories(4.1), and hardly perceived as a luxury item(2.78). The preference for the fruits dressing was highly correlated with the degree of education(p<0.05), age(p<0.001) and BMI(p<0.001). The higher the degree of education, the lower the level of age group, and the lower the BMI, the higher preference for the fruit salad dressing was demonstrated.

This study was conducted to present fundamental data on the physicochemical properties and sensory qualities of salad dressings made with chicken foot gelatin. Preliminary experiments were performed to confirm the gelatin powder concentrations in preparing gelatin solutions. A 2% gelatin solution, including 0.5% agar, was prepared for use in the experiments that followed. Sensory evaluations were conducted to compare the organoleptic acceptance of dressings manufactured with differing concentrations of the additive in seasoning soybean sauce, mayonnaise, and sesame powder. The viscosities of the dressings significantly increased with increasing gelatin powder concentration. A decrease in turbidity was observed in the mayonnaise and sesame dressings. The color difference values of all dressings indicated no changes. In sensory evaluations of dressings prepared with gelatin solutions at different concentrations of 2 g (1%), 4 g (2%), and 8 g (4%) of gelatin powder, the 4 g (2%) sample received the highest score for overall acceptance. From this study, which was conducted to find an efficient use for chicken house wast product, it is anticipated that chicken feet will be utilized as a new raw material for producing collagen and gelatin, protein sources widely increasing in use with in the food and bio-industries.

Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.

BACKGROUND/OBJECTIVES: This study examined the changes in food behaviors of dietary fatty acids over 2007-2018 among Korean adults. SUBJECTS/METHODS: This study used data from the 4th (2007-2009), 5th (2010-2012), 6th (2013-2015), and 7th (2016-2018) Korea National Health and Nutrition Examination Surveys. A total of 46,307 adults aged 19-64 yrs were selected and dietary data were obtained from a single 24-h recall. In the 4th and 7th data, the major food sources for each fatty acid based on the contributing percentage of the food item were compared. The consumption trends in the major food sources were presented as grams per day over 2007-2018 and compared across the survey periods using the multiple regression model. RESULTS: From 2007 to 2018, for total fat, saturated fatty acid (SFA), and monounsaturated fatty acid, the contribution of animal food sources, including beef, chicken, and eggs increased but plant food sources (e.g., tofu, soybean, and plant oil) decreased. As polyunsaturated fatty acid sources, mayonnaise, eggs, and bread showed higher contributions, whereas soybean and tofu showed lower contributions in the 7th data compared to the 4th data. For n-3 fatty acids, the contribution of fish decreased between the 4th and 7th data. Over 12 yrs, the significant increases in the absolute amount of consumption from animal sources were observed. In contrast, decreases in the consumption from plant sources and fish were seen across the survey periods. CONCLUSIONS: In Korean adults, increases in the intake of dietary fatty acids along with changes in the food behaviors during 2007-2018 have evoked great concern for SFA intake, which is a cardiovascular disease risk factor. Healthy food sources of dietary fatty acids should be emphasized in this population.

Objectives: This study evaluated dietary intake and food sources of essential fatty acids in Korean adolescents. Methods: This study was comprised of 3,932 adolescents (9-18 years) who participated in the 2016-2021 Korea National Health and Nutrition Examination Surveys. Dietary intake and food sources of essential fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and linoleic acid (LA) were evaluated using data obtained from one-day 24-hour dietary recall. The proportions of adolescents consuming ALA, EPA + DHA, and LA above or below the adequate intake (AI) of the 2020 Dietary Reference Intakes for Koreans were calculated. All statistical analyses accounted for the complex sampling design effect and appropriate sample weights. Results: The mean intakes of ALA, EPA, DHA, and LA among Korean adolescents were 1.29 g/day, 69.6 mg/day, 166.0 mg/day, and 11.1 g/day, respectively. Boys had higher intakes of all essential fatty acids compared to girls. By age group, adolescents aged 15-18 years showed lower intakes of EPA and DHA compared to adolescents in younger age groups. The 9-11-year-old adolescents had lower intakes of ALA and LA than older adolescents. The proportions of adolescents who consumed more than AI were 35.7% for ALA, 30.4% for EPA + DHA, and 41.5% for LA. Adherence to the AI for ALA did not differ by sex or age group, although boys showed a lower adherence to the AI for EPA + DHA than girls. Major food sources for ALA and LA were plant-based oils, mayonnaise, pork, and eggs. Mackerel was the most significant contributor to EPA and DHA intake (EPA, 22.6%; DHA, 22.2%), followed by laver, squid, and anchovy. Conclusions: The proportion of Korean adolescents who consumed EPA + DHA more than AI was low. Our findings highlight that nutrition education emphasizing an intake of essential fatty acids from healthy food sources is needed among Korean adolescents.
