The objectives of this research were to determine the suitable times of pork slices drying using microwave followed by hot air and to find specific energy consumption during drying. The physical characteristic (color and hardness) and the sensory test of dried pork slices were also investigated. Pork slices with the sizes of 50x50x1.3 and 50x50x2.2 millimeters were dried using the microwave at the powers of 160 320 480 640 and 800 watts until the samples did not burn during drying. Then the samples were dried using hot air at a temperature of 110oC until the moistures of the samples were lower than 20% dry basis. Based on the experimental results it was found that the suitable times of the samples drying using microwave were 50-600 seconds which depended on the microwave powers and the pork thicknesses. In hot air drying period drying times of the samples with thicknesses of 1.3 and 2.2 millimeters were 30 and 45 minutes respectively. The microwave powers had no significant effect on the redness (a value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). The pork thicknesses had the significant effect on the lightness (L value) and yellowness (b value) of dried pork the hardness of dried pork and the specific energy consumption (P<0.05). Moreover sensory scores of the dried pork obtained from this research were close to those obtained from the local market.

This research is studying of an electric field combine with a frying process in a Chinese water chestnut product for reducing oil absorb. An electric field that is used in an experiment will have a stress from 1-3 kV/cm. This will be generated by using a direct current high Voltage from 1066 to 3200 V. which is distributed to an electrode in an uniform and non-uniform of an electric field. This will have a dielectric barrier discharge. There is an analysis for finding a relationship of a moisture on absorbing oil of a Chinese water chestnut fried product due to a moisture has an effect on absorbing oil directly. From an experimental result this is found that the best electric field stress which will have an effect on reducing a moisture of a Chinese water chestnut is an non-uniform electric field form that is created from a direct current high voltage at 3200 V. and this will have an electric field stress at 3 kV/cm. This will have an average of a difference of a moisture at 0.6 g. This will select to use a direct current non-uniform electric field at 3 kV/cm. In an experiment combine with a fried process in a Chinese water chestnuts fried product this is done for reducing of absorbing oil. By this will fry at the temperature of 180๐C for 5 minutes. This is found that this can reduce an absorbing of oil best at 17.93% when this has compared to a Chinese water chestnuts fried that hasn’t passed an electric field.

This research was the basis for the design and development of home furnishings. Plastic woven from strands The woven plastic house hunters Si district seeking offense.The bulk sample from the production community in Angthong to represent the group of 50 people the researchers used a random sample quota (Quota Sampling) to obtain the desired characteristics of the sample. Then accidental sampling (Accidental Sampling) to the full amount required at the point of data collection and consumer groups. The research group defines a consumer as a representative group of 100 researchers by means of random sampling accident (Accidental Sampling) using questionnaires. The research found that The consumer and producer is of the opinion that the same approach in product form. The variance from the statistical products one is different with the two and there is a difference with the three products including the two have differences with the three significant at 0.05 number. three topics including the proper shape the suitability of woven pattern the suitability of the paint used on the products one has different products and the two products three. Significant at 0.05 Number 1 are beautiful and there is no difference between the three topics are appropriate for your size proportion appropriateness of materials used as components the adequacy of benefits. The analysis assessed consumer satisfaction with the products of home furnishings. Woven from plastic The woven plastic house hunters Si district seeking offense that overall consumer satisfaction with the product level. In the subsection are satisfied with the products good deal as well.

The study of utilizing core pineapple and phufa tea in drinking jelly. The purpose of this study and processing in add fiber from core pineapple wasted and Phufa tea in drinking jelly. The resulfs showed that formulation of carageenan was 10 gram because texture had elastic and softness appropriate. Ratio core pineapple juice : Phufa tea was 60 : 40 percentage had sensibility in color order and flavor for Phufa tea and add fiber from core pineapple was 10 gram because texture had elastic softness and easily suck. The consumer acceptability indicated of target consumer accepted the product. Consumer accepted like very much 41% and interested to buy product 83%. The physical attributes were as follows : L* a* b* value 75.20±0.01 1.31±0.01 28.43±0.02 and respectively Aw = 0.973±0.00 and hardness 5.42±0.45 (N). The chemical analysis of product contained pH = 3.52±0.02 Total soluble solid (TSS) = 15±0.00 (°Brix) and crud fiber content 0.602%. The microorganism (TPC) < 10 cfu/g. and yeast and mold < 10 cfu/g.
