การสำรวจความแปรปรวนของคุณภาพข้าวหอมมะลิ Thai Agricultural
Grissana Sudtasarn.
In 2012, surveys were conducted in both the northeast and the upper north of Thailand from seed sources, farmer fields, local mills and rice exporters. Samples were analyzed for grain physical and chemical quality, including a content of 2-Acetyl-1-Pyrroline (2AP). Soil samples were collected from farmer fields and analyzed for soil texture, pH, nutrients and organic matters. The results showed that both physical and chemical qualities of all samples met the standard for Thai Hom Mali rice. The 2AP contents of those samples from seed sources in the northeast were between 1.98-9.42 ppm while the samples from farmer fields were between 1.14-11.84 ppm. The 2AP contents of those samples from mills were between 0.86-7.2 ppm for the upper north, those of seed...

การสำรวจความแปรปรวนของคุณภาพข้าวหอมมะลิ Thai Agricultural
Grissana Sudtasarn.
The survey was conducted in 2013 in order to collect the information on production management of Kao Dawk Mali rice from various sources, i.e. seed sources, farmers' fields, local mills in the area of north eastern and upper northern Thailand, and also from the exporters. The samples of Kao Dawk Mali rice were taken for evaluating their grain physical and chemical properties. The content of 2-Acetyl-1-Pyroline (2AP) of those samples were measured in order to evaluate for their aromatic levels. Soil samples from each farmers' fields were also taken to analyse for soil texture, soil pH, soil nutrients and soil organic matter. The results from grain quality analyses indicated that all samples being analysed had met the standard of Hom Mali rice. The average...

Study on factors affecting Thai Hom Mali rice quality aims to investigate causal factors contributing to rice qualities such as production process, post-harvesting process and storage.This research was carried out in rice growing areas of northeast and upper north of Thailand during 2011-2014. The 5 major projects included in this research were: I) Survey on quality variation of Hom Mali rice II) Effects of water deficit on 2-acetyl-1-pyrroline content, grain yield and grain quality of Khao Dawk Mali 105 (KDML105) and RD15 III) Effects of plantnutrients, sulphur, calcium, manganese and magnesium on 2-acetyl-1-pyrroline content, grain yield and grain quality of KDML105 IV) Postharvest technologies affecting Khao Dawk Mali 105 grain qualities V) Yields...

การเปลี่ยนแปลงคุณสมบัติความหนืดของแป้งและคุณภาพการหุงต้มระหว่างการเก็บรักษาของสายพันธุ์ข้าวนาสวนนาน้ำฝนภาคตะวันออกเฉียงเหนือ Thai Agricultural

Study on changes of starch viscosity and cooking quality of northeastern rainfed lowland rice lines aims to gather basic information on grain quality for each promising line in order to plan for further product development. In 2012, the experiment was conducted on 6 promising lines, which include 5 non-glutinous lines, i.e. UBN03007-47-7-9-7-80-54, UBN03007-47-7-7-26-35-19, UBN03005-6-3-26-10-21-27, UBN02123-50(R)-B-3, UBN03005-6-3-26-10-49-10 and 1 glutinous line; RGD05282-3-3. After harvesting, paddy of each line was dried to 14% moisture content and then kept in granary storage. Samples were taken once a month and analyzed for grain chemical quality and starch viscosity. The results showed that, after 8-month storage, there was no change in amylose...
