การเปลี่ยนแปลงคุณภาพไข่เค็มพอกขมิ้นทดแทนดินจอมปลวกบางส่วนระหว่างการเก็บรักษา
This research aimed to study the quality changes of coating salted eggs partially replacing soil from termite mound with turmeric powder at the level of 0% 5% 15% and 25% during storage for 4 weeks. The results showed that the increasing in turmeric level caused a decrease in salt content in raw egg yolk and raw egg white which led to decrease in hardening ratio of egg yolk. The hardness values of cooked - salted egg yolk decreased while those of cooked - salted egg white slightly increased. At the same salting period the color values of raw egg yolk and raw egg white coated with different levels of turmeric were slightly different. Egg yolks changed to a yellowish orange color while egg whites showed lightness with a direction of red and slightly yellowish color. The raw egg white coated with higher level of turmeric powder exhibited more yellowness which was in accordance with the increasing in curcumin content. From the results of 9-point hedonic scale in terms of color aroma overall taste and overall liking it was found that salted eggs coated with turmeric powder to partially replace soil at a level of 25% with 2 weeks of preserved duration had high scores of sensory acceptability which did not differ significantly from the control samples (0% turmeric) (p>0.05). The curcumin content analyzed in dry egg white was 3.885 mg/g at week 2 and increased to 13.291 and 18.484 mg/g at week 3 and 4 respectively.

This research studied the factors that affect the efficiency of phosphate reduction in the wastewater of the washing process with CaCO3 and CaO produced from eggshell and mussel shell. The study found that the optimum condition for adsorption when using CaCO3 from eggshell is to adjust the pH to be equal to 10 take 15 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing the adsorbent to CaO the optimum condition for phosphate removal is to adjust the pH to 7 take 15 minutes to absorb and add 1 gram of adsorbent which can reduce the phosphate content by 24 percent. The optimum conditions for adsorption when using CaCO3 from mussel shell were to adjust the pH to 10 take 45 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing adsorbents to CaO the optimum condition for phosphate removal is to adjust the pH to 10 take 15 minutes to absorb and add 3 grams of adsorbents which can reduce the phosphate content by 24 percent. In addition when studying the adsorption of impurities in the wastewater such as conductivity turbidity COD and BOD it is found that the optimum reduction conditions can reduce the impurities of the parameters that mentioned above were 19.32 2.60 54.77 and 16.67 percent respectively. CaCO3 and CaO produced from eggshell and mussel shell can be used to absorb impurities in wastewater before releasing into natural water sources.

The objectives of the research on the different egg age affecting the sponge cake were to study the appropriate different egg age to bake the sponge cake and examine the physical and chemical qualities of the sponge cake. The density of the different age cake was measures using the randomized complete block design (RCBD) method at 95% reliability. The quality of senses sight color smell taste and texture and the overall preference were evaluated. The difference of mean was compared with by Duncan New Multiple Rang Test (DMRT) using a computer program to find the appropriate different egg age to bake the sponge cake. 30 testers applied the 5- point hedonic scale to test the product. Research results showed that the testers preferred the egg age at 9 days the most. Ln terms of taste texture and overall preference the mean was 3.70 3.67 and 4.00 respectively. The physical quality test results indicated that the texture of the one-day egg age had the best adhesion and flexibility 0.54 and 0.94 respectively. The egg age at 12 days had the highest lightness (L*) yellowness (b*) and redness (a*) 50.61 4.71 and 23.99 respectively with the statistical significance (p).≤ 0.05
การผลิตไข่เค็มแดงชนิดเค็มน้อยด้วยเกลือและมอลโตเด็กซ์ตริน
This study demonstrates a new concept of salted yolks processing using only the yolk directly with the egg white portion being further utilized. This salting process accelerated the salting time from 4 weeks for whole egg pickling to only 5 days. The results showed that the increasing of amount of salt and maltodextrin in the salt solution (20 and 26% of salt 10 and 20% of maltodextrin) and salting time (0-5 days) resulting in a decrease in the moisture content of the yolk as well as the increase in the amount of salt and fat content in salted yolk. These caused a lower in brightness (L*) and a yellow index (b*) while a higher red index (p<0.05) of salted yolk. Moreover salted yolk has higher hardness cohesiveness gumminess and chewiness while showed lower adhesiveness and springiness which the increasing of salt solution concentration and salting time (p<0.05). Pickling of egg yolks directly in a solution of 20% of sodium chloride mixed with 20% of maltodextrin resulted in the lowest salt content. The comparison of the chemical and physical quality for salted egg yolks this new separted yolk salting generated salted yolks of similar quality to those of commercial salted egg yolks which was produced using the traditional egg-shell method but lower in salt content (p<0.05). Thus this novel salting process can be a guideline for the development of an efficient low-salt egg yolk production method.

This research aims to study Bubble Mesona Chinensis Flavor added with Flaxseed The objective is to study the basic formula of Bubble and to study the quantity of grass jelly juice to substitute water in bubble which has 4 different levels consist of 25 percent 50 percent 75 percent and 100 Percent and to study the flax seed supplementation in Bubble which has 4 different levels consist of 3 percent 6 percent 9 percent and 12 Percent by using the method of randomized complete block design or RCBD. This experimental plan will help assess the sensory quality in appearance color smell taste texture and overall preference by using 9 “Point Hedonic Scale” method. This experimental study used 80 people to test the flavor consist of lecturers and food and nutrition students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The results were calculated the average (𝑥̅) to Analysis of Variance (ANOVA) and compare the mean difference at the confidence level 0.05 by using the method of Least Significant Difference (LSD) and Duncan’s New Multiple Range Test (DMRT). Results from the study of grass jelly juice to substitute water in bubble tasters rated Formula 3 for the highest acceptance for color taste texture and overall preference. The average score was 7.98 7.90 7.91 and 7.89 respectively. The tasters rated the highest acceptance score for Formula 2 in flavor with an average score of 7.73 and appearance. The tasters gave the highest acceptance at Formula 4 with an average of 8.02. When analyzed and compared the mean differences it was found that appearance and color when comparing the mean differences it was found that the appearance and color were statistically significant (P≤0.05) in aroma taste texture and overall preference. There was no significant difference (P> 0.05) Results from study of flax seed supplementation in Bubble tasters rated Recipe 1 for the highest acceptance for aroma and taste with a mean score of 7.92 and 7.92 respectively for appearance color and overall preference. 8.06 and 7.95 respectively texture. The tasters rated the same score between Formula 1 and Formula 2 with a mean score of 7.94. when analyzing and comparing the mean difference it was found that Appearance color smell taste and texture There was a statistically significant difference (P≤0.05).
