การพัฒนาผลิตภัณฑ์ปลาดุกแดดเดียวของวิสาหกิจชุมชน โดยใช้ตู้อบพลังงานแสงอาทิตย์ ‘รุ่นหลังเต่า’ (COMMERCIAL PRODUCT DEVELOPMENT OF SEMI-DRIED CATFISH FOR COMMUNITY ENTERPRISE BY THE SOLAR DRYER CABINET ‘HLANG TAO MODEL’)

This research objectives were to development semi-dried catfish with the solar dryer cabinet “HLANG TAO MODEL”, and to examine sensory acceptability tests to select product standards suitable for analyzing chemical, physical, and microbial quality. It is a collaborative work between the university and the community to develop and promote quality of semi-dried catfish products in the community. To develop semi-dried catfish with the solar dryer cabinet, three recipes were tested. They included recipe 3 (fish: water: fish sauce = 100: 50: 40 by weight), recipe 3.1 (fish: water: fish sauce: sugar = 100: 50: 40: 10 by weight), and recipe 3.2 (fish: water: fish sauce: sugar = 100: 50: 35: 15 by weight). The finished products were tested for the acceptance by 120 consumers. The sensory test showed that the most accepted community product by consumers was recipe 3.2. Consumers evaluated semi-dried catfish products for acceptability of appearance, color, aroma, taste and overall liking. A binomial (yes/no) scale was employed to evaluate the overall acceptance and purchase intent. The results revealed that the overall liking score of semi-dried catfish products was over 6.00 (on a 9-point scale) within positive acceptance (86.2%) and purchase intent (95.83%). The chemical compositions of semi-dried catfish products of moisture, ash, protein, lipid, fiber and salt contents were 54.84, 4.84, 27.21, 9.83 and 3.18, respectively. Lactic acid, Trimethylamine (TMA) and Total volatile base (TVB) content were 0.28, 7.87 and 1.34 mg.N/100g sample, respectively. The physical compositions of semi-dried catfish products consisting of L*, a*, b*, water activity (aw) and pH were 42.33, 4.76, 15.64, 0.78 and 6.44 respectively. The results of the microbiological criterion followed a standard. The community product obtained by drying with this solar dryer cabinet “HLANG TAO MODEL” were of high quality and hygienic hygiene.
