农产品质量安全问题受到了党和政府的极大关注。这也是应对入世挑战。提高我国农产品市场竞争力的一个重要方面。麻类产品在提高质量的同时，应加强安全生产监管，对生产中使用的农药、化肥、除草剂、重金属、化工原料、化学辅料等要严加控制；应推行市场准入制，加强对产品中有毒有害物质的检测；应完善质量保障体系，健全标准体系。打破欧盟的“技术壁垒”，建立我国的技术壁垒措施。 相似文献

In this paper, the bast of the Kosteletzkya virginica are degummed and separated into fine fibers, the chemical composition, morphology, microstructure and mechanical properties
of the Kosteletzkya virginica bast fibers are characterized by means of SEM, ART-FTIR, DSC-TGA, XRD and Instron tensile tester. The results show that the
surface of the Kosteletzkya virginica bast fibers is smooth, and there are many visible grooves along the vertical section. Typical cellulose I in the Kosteletzkya virginica bast fibers is confirmed by FTIR and XRD analysis. The crystallinity of the Kosteletzkya virginica bast fibers is higher than that of the cotton fibers and lower than that of the castor-oil plant bast fibers. The beginning
and maximum decomposition temperature of the Kosteletzkya virginica bast fibers are 252 and 347 °C respectively, which indicate that the Kosteletzkya virginica bast fibers have an appropriate thermal stability. The Kosteletzkya virginica bast fibers have a better mechanical properties and excellent hygroscopicity. All the results show that the Kosteletzkya virginica bast fiber is one of an ideal candidate for the new textile material. 相似文献

Fiber fineness characteristics are important for yarn production and quality. In this paper, degummed bast fibers such as
hemp, flax and ramie have been examined with the Optical Fiber Diameter Analyzer (OFDA100 and OFDA2000) systems for fiber
fineness, in comparison with the conventional image analysis and the Wira airflow tester. The correlation between the results
from these measurements was analysed. The results indicate that there is a significant linear co-relation between the fiber
fineness measurement results obtained from those different systems. In addition, the mean fiber width and its coefficient
of variation obtained from the OFDA100 system are smaller than those obtained from the OFDA2000 system, due to the difference
in sample preparation methods. The OFDA2000 system can also measure the fiber fineness profile along the bast fiber plants,
which can be useful for plant breeding. 相似文献

Samples of kenaf (Hibiscus cannabinus) grown in Malaysia were examined to determine the kraft pulp and papermaking properties of their bast (or bark) fibers. Using kraft pulping process showed that bast fibers were relatively easy to cook resulting good pulp yields in the range of 45–51%. The bast pulp produced sheets with great density, tear index and dry zero-span breaking length. Kenaf bast fiber is considered promising for production of high-grade printing, writing and specialty papers. 相似文献

Seed processing and testing hold the key to the market circulation of seeds, and are an indispensable link in commercial breeding to endow seeds with commodity attributes. The research of seed processing and testing theory and technology is an important link in improving the seed industry chain, realizing large-scale commercial breeding and consolidating the seed industry science of ‘integration of breeding, propagation and promotion’. The scientific and technological system of seed industry in China is being formed and perfected, which is subject to the development level of the industry. The theory and technology of seed processing and testing are relatively weak. We reviewed the development of seed processing and testing theory and technology, and put forward strategies and suggestions to improve the sound development of China’s seed industry. In order to meet the needs of seed industry development and on the basis of high quality breeding of varieties, the new directions and demands of seed processing and testing theory and technology were analyzed. We will work to strengthen the applied research of seed industry, establish advanced seed quality inspection system, improve seed processing equipment suitable for the development needs of modern seed industry, establish standardized production system of seed processing industry, develop the scientific and technological disciplines of seed industry, and promote the sustainable and healthy development of seed industry. 相似文献
