การใช้สารฟีนอลิกจากดอกชมจันทร์ในการผลิตนมพาสเจอไรซ์
The fresh moonflower (FM) was dried in hot air oven at 50 C 48 hours as the dried moonflower (DM) 7.37 %. Then DM was extracted by ethanol concentration 95% and using the evaporator to evaporate ethanol solution. This study aimed to study the process which extract phenolic compounds (PC) from FM and formulate PC in pasteurized milk. From the results PC was 68.11±1.44 μg/ml. The final formula of pasteurized milk was added PC 1g /200 ml and was pasteurized at 72 °C 15 s. The (L*) 85.91±0.07 (b *) -1.92±0.06 (a *) 17.13±0.24 pH 6.58±0.00 total soluble solid 12 ˚Brix. It could be stored at 4 C for 7 days.

The purpose is to study the factors that affect the population of the marketing mix consumer pearl milk tea: Tea More case study to compare the effect of the marketing mix of consumers. The sample used in this study include pearl milk tea: Tea More Case Study which has a branch located in the Sukhumvit area. Bangkok The storage From the sample of use services at Pearl Milk Tea More 400 using statistics to analyze the data including the frequency of the Mean ( X ) the standard deviation ( . .DS ) and inferential statistics by analyzing the one-way ANOVA using statistical t-Test F-Test and crossover frequency distribution table. (Cross-tabulation) analysis conclusion. 1. Analysis respondents. Most are male aged 21-30 years with a single level of undergraduate studies. The average monthly income of less than 15000 baht a career and most other states including student groups. 2. Analysis of factors affecting the personal consumption pearl milk tea: Tea More Case Study found that gender age education level age and different opinions on products pricing channel distribution locations. the field of marketing is different except for the age difference. As a result the products factor Price Channel Promotion and marketing is no different. 3. Behavior Analysis found that female consumers pearl milk tea pearls consumption than men. And those aged less than 20 years of education than a bachelors degree. And those earning more than 55000 baht to consume more than six cups a week. Most are intended for consumption. Preference in the product and the taste which over time with most consumers and the afternoon. For products that are of interest most consumers. Including traditional milk And the toppings are a consumer favorite pearls. The person influencing the consumption of milk pearls are very self. Subsequent research suggested that there should be a comparison of the goods or services which are similar to features. Cons of goods and services The obvious question should be added to the comprehensive control.

The purposes of this research were to design and create dyed silk yarn and cotton yarn machine for community enterprises of Ban Na Pho woven group Na Pho district Buriram province. All materials were made of stainless steel and the principle of rotation of the yarn skein which was hung with spindle yarn inside the dye tank. Dyeing process began by mixing color tanks in the exterior size for diameter ๓๐๐ mm. Adjust the temperature inside the dye bag by the boiler was attached below. Using pump in dye tank for rotating the heat with stainless steel pipe in ๑๑/๒ inches and ๓ inches x ๑/๒ inches and the rectangular tank was ๖๐ cm. wide ๙๐ cm long and ๑๖๐ cm. high. It had ๕ mm. of plastic lid cover in front of and a channel that looked at the attachment of color yarn. The lid had ๒ levels adjustable lift spring lock and ๒-axis spindle yarn. It was triangular shaped drilled holes spray to ๑ mm. on the spindle with a diameter of ๑๕ cm. and ๖๐ cm. long rotating at ๑๐ rpm strength by using electric motor size ๐.๕ HP used ๒๒๐ volts. It could be rotated left and right with the gear ratios around ๒๐:๑ ๒ adjustable that were automatic with programming on the control box and simple pattern. the spray dyed paint had ๑ liter water pump to control pressure valve for opening and closing to dyed water flow regularly by the heat from the LPG gas with a head size of ๓๐ cm. and adjust the temperature up to ๑๒๐ Celsius degree. It was showed the temperature measurement of water dye with pressure gauge and temperature gauge. The efficiency of this dye can be dyed silk yarn and cotton yarn per ๕ kg. to ๑๐ kg. which was a medium-sized textile production to the local community enterprise and applied in the preparation of yarns before dying such as peeling glue and bleaching.

The purpose of this project is to study the mechanical and physical properties of recycled roofing materials. The pulp extracted from the UHT beverage boxes to get aluminum foil mixed with low density polyethylene. This can be used engineering and is an option to reduce the amount of UHT boxes left over to roofing sheets. In experiment 3 aluminum foil medium size and fine then hot and extruded with 68 and 10 bar compression then cut into test pieces. To test mechanical and physical properties in accordance with the test standards: Torsion Testing Tensile strength Impact resistance Heat resistance water absorption and density testing. Compare the mechanical and physical properties of the material; different sizes of aluminum foil and compressive strength. To bring the best materials to the product. From the tests it was found that the properties of recycled composite materials From the box UHT beetroot This is made of coarse aluminum foil. 18.23 MPa bending strength 10.66 MPa tensile strength 110.987 J / m2 impact resistance 52.40 Shore-D Hardness 0.62 % Water Absorption 0.70 % Thickness Swelling 1.086 g/m3 Density 0.031 m2.K/W Thermal Resistance and 0.291 W/mK Thermal Conductivity is the best mechanical properties. Due to the large aluminum foil it can be used for high strength. Which is higher than the aluminum foil of a smaller size.

This research aims to develop the cement board from vesicular basalt fragment. The 5 ratios of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water are equal to 1: 2: 0: 0.03: 0.5 1: 2: 2: 0.03: 0.5 1: 2: 4: 0.03: 0.55 1: 2: 6: 0.03: 0.6 and 1 : 2 : 8: 0.03: 0.65 by weight. The cement boards were produced by compression machine. The property tests of cement-bonded fiberboard followed the TIS. 878-1994 standard (cement bonded particle board: high density). From the results 1: 2: 4: 0.03: 0.55 is the most suitable ratio of cement board from coconut shell ash. This developed cement boards can apply the vesicular basalt fragment to use as the construction materials with light-weight high strength good thermal insulation and moisture protection properties
