 หัวเรื่อง:การพัฒนาอาหารว่างพลังงานต่ำจากข้าวกล้องโดยเครื่องเอ็กซทรูเดอร์สกรูคู่ ผู้เขียน: ดร.เนตรนภิส วัฒนสุชาติ ,  เพลินใจ ตังคณะกุล, Pracha Boonyasirikool สื่อสิ่งพิมพ์:pdf AbstractHigh fiber, low calorie snack products from unpolished rice, processed by Hermann Berstorff Laboratory Co-rotating Twin Screw Extruder ZE 25x33D was studied. Puffed unpolished rice was mixed with roasted peanut, sesame seed or sunflower seed, or pumpkin, corn or mungbean flake, and shaped using gel binder. The result of 9-hedonic evaluation showed that puffed unpolished rice mixed with corn flake, had higher scores of appearance, odor, taste and acceptability than other formulas. However, scores of all formulas were rather low according to hard crispy texture of 100% unpolished rice. To obtain better characteristics, 25% polished rice was added to unpolished rice and the texture became soft crispyness with acceptability more than other proportions. Chemical analysis showed that puffed rice mixed with mungbean flake contained the lowest calorie contents of 56.9 kcal/ 15 gram serving size and fiber content at 6 percent while sesame seed mixed with unpolished rice had the highest fiber content of 8.5 percent. For shelf life study, it was indicated that during 4 to 6 months storage at 26-27?C, 65%RH, peroxide value (PV) of hulled rice mixed with peanut or corn flake, packed in four layers laminating bags were not changed. But PV of sample with peanut packed in two plastic bags (polypropylene, PP) for 4 months was increased from 2.38 to 13.7 meq/kg, when kept until 6 months it was increased to 19.07 meq/kg. At the period of 6 months, corn flake mixed with unpolished rice showed lower changes of PV than peanut formula in either type of packagings. Moreover those formulas packed in laminated bags had PV and moisture contents lower than packed in PP bags. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Protein Bioavailability – Lowering in Rats Fed High Dietary Fiber from Cereal and Nata De Coco) ผู้เขียน:ดร.วันเพ็ญ มีสมญา , นางสาวเยาวดี คุปตะพันธ์, นางสาวดวงจันทร์ เฮงสวัสดิ์, เพลินใจ ตังคณะกุล, Sureepan Boonvisut, Somsri Poosimuang สื่อสิ่งพิมพ์:pdf AbstractThe comparative effects of 6 different high dietary fiber diets and casein diet on protein bioavailability (protein efficiency ratio, net protein utilization, biological value and digestibility) were investigated by feeding male Sprague – Dawley rats with diets containing unpolished rice, mung bean, sweet corn, nata de coco, milk powder, sugar (formula 1); pumpkin, mung bean, unpolished rice, nata de coco, milk powder, sugar (formula 3); oat, sweetpotato, kidney bean, nata de coco, milk powder, sugar (formula 5); formula 2, 4, 6 containing the same raw materials as formula 1, 3, 5 but without milk powder and sugar. Six experimental diets and control diet (casein) were prepared from 6 formulas by AOAC, contained 10 ? 0.3% test protein, 8% oil, 5% water, 5% mineral, 1% vitamin, 1% cellulose, 35% sucrose, 35% corn starch and different dietary fiber. Total dietary fiber in diet 6 was the highest with it being 20.01g/100 g but the casein diet was the lowest with 6.58 g/100 g whereas in diet 1-5 the dietary fiber ranged from 8.41 to 13.22 g/100 g . The value of protein efficiency ratio in diets 1-7 was 2.44, 1.89, 2.29, 1.66, 2.55, 1.88 and 2.50 respectively whereas net protein utilization and digestibility in diets 1-7 were 63.81 – 77.45 and 70.05-95.52 respectively. Net protein utilization and digestibility in the casein group showed the highest values of 77.45 and 95.52 respectively. The range of biological values in diet 1-7 was 80.29 – 91.76 . The results indicate the highest dietary fiber diet showed the highest content of feces and decreased the value of net protein utilization and digestibility. |
