 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Some Chemical Treatments on Kluai Khai Through Tissue Culture for Mutation Breeding) ผู้เขียน:ดร.ภาสันต์ ศารทูลทัต, ผู้ช่วยศาสตราจารย์ , นางเบญจมาศ ศิลาย้อย, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractPolyploidy of in vitro Kluai Khai plantlets were induced by different concentrations of the two mutagens : 0, 0.5, 0.75 and 1% colchicine and 0,15, 30, 45mM oryzalin containing 2% DMSO for 2.5, 5.0, 7.5 hours. It was found that the higher the mutagen doses and the longer the treatment duration, the less the survival rates. After treating plantlets with colchicine and oryzalin at 0.4, 0.5, 0.75% and 13, 15, 22mM, respectively the survival rate of each one was found to be 50%. In MV1, adventitious bud initiation of mutagenic treatment yielded 0.2-1.2 shoots which was lower than those in the control while those of MV2 and MV3 were not significantly different from each other. Treated plantlets were revealed to be abnormal in chimera and stomata sizes were larger than those of the controls. The plantlets with stomata over 28mm were selected for chomosome count. The controls were diploid (2n = 22) whereas three selected clones were tetraploid (2n = 44) derived from 1% colchicine at 7.5 hours and 45mM oryzalin at 2.5 hours. The mutants were then subcultured. The number of suckers of mutants was less than those of the control. MS medium without plant growth regulator was observed to give the best rooting of all treatments. After transfered to the greenhouse, the height of the controls and the colchicine treated plants were revealed to be significantly different from the oryzalin treated ones which were shorter with low survival rate. The results obtained in the field were similar to those in the greenhouse. The foliage of all mutants appeared more drooping with larger stomata cell, lower in stomata number per area and thicker than those of the controls. The numbers of leaf and sucker of each mutant were not significantly different from the controls. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Chemical Treatments to Reduce the Bitterness and Drying on Chemical Physical and Functional Properties of Dietary Fiber Pomelo Powder from Citrus grandis (L.) Osbe ผู้เขียน:Suwanna Pichaiyongvongdee, Boonyakrit Rattanapun สื่อสิ่งพิมพ์:pdf AbstractThe pomelo albedo was selected from three cultivars—Kao Nampung (KNP), Thongdee (TD) and Kao Yai (KY). KNP was a suitable cultivar for preparing dietary fiber powder because it had high crude fiber content and the limonin and naringin contents were lower than for TD and KY. Limonin and naringin are the main bitter components of pomelo albedo which need to be reduced. Three chemicals were used to reduce the bitterness of the pomelo albedo—NaCl (1%, 3%, 5%), CaCO3 (1%, 3%, 5%) as well as various pH levels using 0.1 N NaOH solution (pH 7, 8 and 9). The results showed that all chemicals treatment could reduce the limonin and naringin contents (P ? 0.05) but adjusting the organoleptic quality to pH 7 had the highest odor score and the lowest score for bitterness. Two drying methods were studied: freeze drying was conducted at -40 ?C for 14 hr and the three conditions for tray drying were 50 ?C for 5.5 hr, 60 ?C for 4.5 hr and 70 ?C for 2 hr. The freeze dried pomelo albedo powder had better physical, chemical and functional properties than the samples that were tray dried (P ? 0.05). The water holding capacity and swelling capacity of the dietary fiber pomelo albedo powder were compared with commercial cellulose (carboxymethyl cellulose). It was found that the pomelo albedo dietary fiber powder had better functional properties than the commercial cellulose based on scanning electron microscopy. Thus, dietary fiber pomelo albedo powder can be used as a functional ingredient or in industrial applications using food products. |
