The effects of oil concentration and stabilizers and emulsifiers on the emulsion stability of mayonnaise were studied. The highest viscosity of mayonnaise and the least amount of oil separation were by the additon of soluble starch, but when it was added below 0.6%, the viscosity of a mayonnaise decreased sharply during storage at 3$0^{\circ}C$. The stability of mayonnaise was increased only when the soluble starch was added to mayonnaise above 0.9%. When xanthan gum was added at the concentration of 0.05~0.1%, the viscosity of mayonnaise was increased considerably and the emulsion stability was improve. But if it was added more than at 0.2% on the contrary, the emulsion stability was reduced and the texture of mayonnaise was changed. When both 0.1%-xanthan gum and 0.3%-soluble starch were added, the most stable mayonnaise was obtained.

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 objective of this study was to investigate the difference of oxidative stability between DHA (docosahexaenoic acid) added and not added commercial mayonnaise, and then to find out stable condition for maintaining the quality of DHA added mayonnaise. During the storage at room temperature $(25^{\circ}C{\pm}1^{\circ}C)$, it showed that DHA added commercial mayonnaise was more sensitive to oxidation than DHA not added commercial mayonnaise. And sensory quality of DHA added commercial mayonnaise decreased drastically after 5 months from the production date of mayonnaise. During the storage at low temperature $(4^{\circ}C{\pm}1^{\circ}C)$, DHA added mayonnaise was also more sensitive to oxidation than DHA not added mayonnaise, but it showed no apparent and sensory problem with both samples during 8 months of cold storage test periods. In considering the distribution condition of mayonnaise in the country, it was suggested that shelf-life of the DHA added commercial mayonnaise should be shortened 2 or 3 months than that of the DHA not added commercial mayonnaise.

The objective of the present study was to develop cholesterol-reduced and phytosterol-supplemented mayonnaise using crosslinked $\beta$-cyclodextrin and examine its physicochemical and sensory attributes during 10 months of storage. The composition of cholesterol-reduced phytosterol-supplemented mayonnaise was similar to the control. The amount of cholesterol removed ranged from 90.67 to 92.47%. The TBA absorbance of the samples showed that the more phytosterol the sample contained, the lower the TBA absorbance value. The viscosity of cholesterol-reduced mayonnaise with 2.0% phytosterol decreased significantly during storage (p<0.05). The color changes of mayonnaise during storage showed a decrease in the L- and b-values, and an increase in the a-value. The experimental mayonnaise maintained emulsion stability, which was significantly lower in 2.0% phytosterol-supplemented mayonnaise. With regard to sensory attributes, most characteristics were similar to the control mayonnaise, however, the addition of phytosterol had a negative effect on stickiness and bitterness. These results indicate that the cholesterol-reduced and phytosterol-supplemented mayonnaise has decreased oxidation and maintains most of its physicochemical and sensory properties during storage.

The purpose of this study was to investigate the oxidative stability of green tea-added mayonnaise during storage at 5, 15 and 25$\^{C}$. Mayonnaise was prepared with salad oil, egg yolk, sugar, salt and vinegar, and added with 0.1, 0.3 and 0.5% of green tea powder for experiment. Peroxide values (POV) of each mayonnaise were compared during storage for 13 weeks. POVs of control mayonnaise stored at 5, 15 and 25$\^{C}$ for 13 weeks were 28.0, 63.5 and 144.4 meq/kg, respectively. Oxidative stability of green tea-added mayonnaise was increased with increasing concentration of green tea in mayonnaise, but it was decreased with increasing storage temperature. The addition of green tea at 0.5% extended the induction period of mayonnaise significantly (p<0.05) at each temperature. Relative antioxidant effect (RAE) of mayonnaise containing 0.1% of green tea were 226%, 188% and 143% during storage at 5, 15 and 25$\^{C}$, respectively, and it was increased with increasing green tea concentration in mayonnaise. The results suggested that the use of green tea is valuable to inhibit the oxidation of mayonnaise as a natural antioxidant.

This study was conducted to develop an organic control of powdery mildews of cucumber by using mayonnaise in green house. The treatment of 0.1~2% mayonnaise resulted in 8.3%~99.2% control efficiencies against powdery mildew of cucumber. 0.5% mayonnaise treatment resulted control values over 97% in disease. It did not adversely affected the photosynthesis of foliages. Although one application of mayonnaise to the foliage was not practically effective enough, two or three application of mayonnaise to the foliage at the 0.5% concentration resulted in excellent control against powdery mildews. This treatment could provide protection for 10~14 days after application. Among the type of mayonnaise, general mayonnaise revealed 97.5% control value, but mayonnaise containing low oil content revealed 39.3%~97.5% control values on powdery mildews at the 0.5% concentration. Therefore, oil content in mayonnaise played a essential material to control powdery mildew. Results indicated that mayonnaise could be used as organic control of powdery mildews of cucumber. This control might be environmentfriendly as well as cost-effective.

This study investigates the characteristics of mayonnaise adding yuza juice, a byproduct of yuza tea, to it. The mayonnaise was prepared by adding yuza juice at 0(control), 25, 50, 75, 100%. In order to analyze the characteristics of the mayonnaise, we examined the color, viscosity, emulsion stability and sensory acceptability. The L, a, ${\Delta}E$ values of mayonnaise mixed with yuza juice were similar to or lower than control. As the content of yuza juice increased, the viscosity and emulsion stability, that is the physical quality of the mayonnaise, improved significantly(p<0.05). With regard to sensory evaluation, mayonnaise mixed with yuza juice had better flavor, taste, texture and overall acceptability(p<0.05). These results suggest that yuza juice is good ingredient to improve the quality and sensory acceptability of mayonnaise.

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.

Four kinds of low calorie mayonnaises containing 1.2% of sodium alginate, 1.0% of guar gum, 1.0% and 1.2% of xanthan gum and one control mayonnaise containing 78.5% of oil without gums were manufactured in pilot scale. Fresh control mayonnaise was higher in viscosity and turbidity than low calorie mayonnaise with gums. During storage at -1$0^{\circ}C$, viscosity and turbidity of control mayonnaise decreased sharply, whereas those of low calorie mayonnaise with gums decreased slightly. Scanning electron microscopy showed that fresh mayonnaise was composed of heterogeneous population of dispersed spherical oil droplets (<10 ${\mu}{\textrm}{m}$), and oil droplet size of control mayonnaise was smaller than any other low calorie mayonnaise. During storage at -1$0^{\circ}C$, a shift in oil droplet size toward larger oil droplets was frequently observed in control mayonnaise as a result of coalescence of oil droplets. Oil separation and turbidimetric study also confirmed that coalescence of oil droplets was occurring during this accelerated aging treatments.

Appropriate types and concentrations of starch-based fat replacers which are low-pH stable, shear resistant and heat stable were selected to develop reduced-fat mayonnaise without affecting taste, texture and emulsion stability. Four kinds of commercial fat replacers [Neutral DR (DR), Stellar 100X (SX), Sta Slim 150 (SS) and N-Lite L (NL)] were thermally activated after appropriately hydrated and applied to mayonnaise formulation. For each fat replacer, eight recipes having various ratios of soybean oil/fat replacer(95/5 to 60/40) were formulated and compared with standard formulation(100% soybean oil) using rheological and sensory evaluations. All tested starch pastes showed pseudoplastic behavior, time-dependent thixotropic gel characteristics. The increasing order of pseudoplasticity and yield stress was RM, NL, SS and ST. The hardness and adhesiveness of each fat replacer-added mayonnaise was increased in the same order as above. Formulated mayonnaise which contained higher ratio of fat replacer showed lower values in hardness and adhesiveness. ST at up to 25% oil replacement exhibited the highest oil replacing ability among four replacers. ST-added mayonnaise also exhibited the highest sensory score and emulsion stability among all products including standard formula. The high sensory score in spreadability of RM-added mayonnaise well reflected the consistent index of RM paste. Use of fat replacers reduced oily odor and greasy aftertaste of mayonnaise.
