如何提高稻米营养价值和附加值,积极开展稻米加工副产品综合利用是我国碾米行业共同关心的问题。我国是世界上最大的稻米生产国和稻米消费国,稻米也是我国的主要粮食品种,正常年景年产稻谷约2亿t,约占世界稻米产量的1/3,占我国粮食产量的2/5、我国约有8亿人口以稻米为主食,每年直接食用稻米及其制品耗用稻米约1.3~1.4亿t。所以,稻米及其制品的消费市场是我国最大、最稳定的粮食消费市场之一。 相似文献

Rice flour is a starchy material with low-cost, because it can be produced from rice that is broken during processing. The aim of this study was to develop biodegradable films based on rice starch and rice flour, and to characterize their physicochemical, microscopic and mechanical properties. Films from rice starch and rice flour were prepared by casting, with glycerol or sorbitol as plasticizer. SEM analysis of starch and flour films revealed compact structures. Rice flour films prepared in the present work have similar mechanical properties to those of starch based films. However, their water vapor permeabilities are two times higher than those of starch based films. Films with sorbitol were less permeable to water and more rigid, while films with glycerol are more plasticized and have poorer water vapor barrier properties. Therefore, preparing edible films from rice flour is a new alternative for using this raw material, which is sometimes much cheaper than commercial starches. 相似文献

The acidic condition of soil intervened crop growth, especially for rice crop. This research aimed to examine whether application of SRI method on saline soil can improve the productivity of rice. This research applied SRI method in the hinterland of mangrove forest areas around Segara Anakan Lagoon of Indonesia through modified irrigation to reduce saline water intrusion. SRI along with deep furrows in this first implementation had reduced the use of synthetic fertilizers by 40%, reduced variable costs by 8.35%, increased the B/C ratio by 95% and crop productivity by 76% compared to the control methods and increased the B/C ratio by 161% and crop productivity by 133% compared to conventional methods. The farmer’s motivation to apply SRI along with deep furrows for both N-Ach and N-Aff majority was distributed from moderate to high. 相似文献

Glutinous and non-glutinous rice hybrids derived from IRRI and Lao PDR rice germplasm were evaluated for yield heterosis and genetic diversity based on SSR markers. Pollen and spikelet fertilities of the hybrids showed absence of effective restorer and maintainer genes in the Lao varieties for WA-CMS cytoplasm. Positive heterosis over better or male parent (Lao varieties) was observed. Hybrids derived from an IRRIs TGMS line with Lao varieties showed a great potential in hybrid rice application. Genetic diversity among the rice lines was assessed by COP and SSR markers. Cluster analysis based on the molecular markers generated three parental groups in agreement with parental pedigree information. Significant linear relation was detected between yield heterosis and marker-based genetic distance of parents. 相似文献
