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 aimed to study the use of coarse aggregate obtained from removing old recycled asphalt pavement (RAP) in the production of the porous concrete paving block. Crushing and size separation of the coarse aggregate by using standard sieve size by selected the gradation size of the coarse aggregate that passed to sieve size 1/2” and retained on sieve size 3/8” and other that passed to sieve size 3/8” and retained on sieve size No.4 by mixing ratio 50 : 50 of the mass as replaced natural coarse aggregate. Portland cement quantity about 18% and 20% by weight of the aggregate. The water to cement ratio was 0.30 and 0.35 respectively. Compressive strength flexural strength and water permeability were investigated. The results showed that the cement content and water to cement ratio was influenced the strength properties and water permeability rate of the porous concrete paving block. The porous concrete paving block mixed with higher cement content (20%) had the compressive strength at the age of 28 days increased by 16-24% when compared with lower cement content (18%). On the other hand the water permeability rate decreased by 5.1-8.1%.
ผลของปริมาณแป้งกล้วยหอมเขียวทดแทนแป้งสาลีที่มีต่อคุณลักษณะของขนมปัง
The objective of this research was to study the effect of substitution of wheat flour with Cavendish banana flour on specific volume density antioxidant activity and the sensory acceptance of bread using Cavendish banana flour instead of wheat flour as 0% (control) 10% 20% and 30% of the total flour weight. It was found that an increasing amount of Cavendish banana flour caused the darker of the bread appearance and the specific volume of the bread decreased from 4.22 to 2.69 cm3/g while the bread density increased from 0.24 to 0.37 g/cm3. The total phenolic content and antioxidant activity of the bread made of Cavendish banana flour instead of wheat flour were significantly greater than the control bread (p<0.05). Also the sensory acceptance scores by panelists in terms of appearance color aroma taste texture and overall acceptance of bread using 10-30% of Cavendish banana flour content were not significantly different compared to the control bread (p>0.05) . Therefore the bread using 30% Cavendish banana flour gave the highest amount of total phenolic compounds and antioxidant activity with well accepted by consumers.

Purpose of this Using dried bananas to replace in Kanom Thong Muan the objective is to study the basic formula for Kanom Thong Muan in 3 formula and to study Using dried bananas to replace in Kanom Thong Muan were basic formula replace 20% 40% and60% By planning randomized complete block design (RCBD) and evaluating sensory quality in appearance (thin consistent) color odor taste texture (crumbly) and overall preference with the use of tasting methods for 9-Point Hedonic Scale. The study the basic formula for Kanom Thong Muan By allowing 40 tasters and the study this Using dried bananas to replace in Kanom Thong Muan By allowing 80 tasters to be undergraduates in foods and nutrition Faculty of Home Economics Technology Rajamangala University of Technology Phranakhon. Take average data (Mean) analyze variance (Analysis of Variance ANOVA) and compare different mean values (Duncan’s New Multiple Test DMRT) The results of the 3 basic formulas of Kanom Thong Muan namely formula 1 formula 2 formula 3 found that the tasting person accepted the formula 1 in appearance (thin consistent) color odor taste texture (crumbly) and overall preference. Average 8.20 7.90 7.85 8.05 8.30 and 8.15 respectively when analyzed Variance and comparison of differences found that appearance (thin consistent) color odor taste texture (crumbly) and overall preference There are significant differences at the level of 0.05. The results of the study of the amount of dried bananas that replaced sugar in 4 formula found that the tasting person accepted the formula replace 20% in appearance (thin consistent) color odor taste texture (crumbly) and overall preference average of 8.09 8.00 7.80 7.83 8.09 and 8.00 respectively when analyzed (3) Variance and comparison of statistical differences found that appearance (thin consistent) color odor taste texture (crumbly) and overall preference There are significant differences at the level of 0.05.

In order to maintain food and materials including drying products at the original dried condition silica gel can be one choice for absorbing moisture. Most silica gel is packed in an Parcel made from plastic which is difficult to naturally degrade thus causing environmental problems. This research therefore have developed packaging material from agricultural waste corn husks for absorbing moisture from food rice. From the study it was found that the corn husk paper had characteristic of smooth paper surface. When making it into a corn fiber Parcel its maximum moisture absorption from saturated humidity was 9.22±0.92% and it could absorb the moisture from the rice stored at room temperature when compared to the plastic sachet at 8.26±0.50% and 9.30±0.08% respectively. When coated with kaffir lime oil extract the corn husk Parcel had the capability in anti-fungus commonly habituated in corn husks up the concentration of 15000 ppm. It could naturally be degraded within 12 days. Therefore with these advantageous qualification the natural Parcel made of corn husk paper harboring silica is for moisture absorption as sustainable and environmental conservation material.
