目的比较中国和美国小麦检验标准差异。方法对我国与美国小麦检验标准、品质分级、污染物及农药残留等方面进行比较分析,对我国进口小麦存在的检验问题进行探讨。结果美国标准中品质、农药残留的检测项目多且限量严格,中国对小麦污染物的检测项目要多于美国,美国对于小麦的等级分类指标更全面、系统化,可以更好地评价小麦等级品质。结论结合我国小麦检验的实际情况及国外先进经验,提出我国小麦质量标准系统存在的主要问题和发展方向,对我国进出口小麦的检验检疫工作提供帮助。 相似文献

豆制品标准在我国已经发展了半个世纪,为我国豆制品行业的发展做出了重要的贡献,然而近年来豆制品质量安全事件频繁发生,导致人们对我国现行的豆制品标准体系进行反思.本文对我国豆制品标准体系现状进行了研究和分析,发现目前我国共有豆制品国家标准35个,行业标准32个,地方标准25个,企业标准5个,已初步形成了一个较为完善的豆制品标准体系.然而标准体系仍存在覆盖面不全,重要标准缺失、缺乏系统性和配套性等问题.据此,本文提出了进一步完善我国豆制品标准体系的修订建议. 相似文献

ABSTRACT
Response surface methodology was applied to develop a standard method for gluten peak tester. Four variables – flour weight, temperature, solvent and rpm – were varied as per the center composite design, and the responses – torque and peak maximum time – were analyzed. Flour–solvent interaction was observed to be the most significant factor impacting the peak torque for whole meal and hard wheat flours while flour (g) and rpm were the most significant for soft wheat flour and insignificant for whole meal flour. The setting 8.5 g flour, 9.5 g solvent (0.5 M CaCl2), 34C temperature and 1,900 rpm was obtained as the standard setting applicable to whole meal as well as refined flours from soft and hard wheats.PRACTICAL APPLICATIONS
Gluten quality is an important criterion to predict flour performance in cereal processing industry. The gluten peak tester has been recently introduced as a sensitive and rapid way of testing wheat gluten quality. The current research was designed to optimize the gluten peak tester to work with wheat varieties with a wide range of protein contents so as to lay a baseline for method development to assess gluten quality of different wheat varieties/lines within a short time span with minimum sample requirements which is very critical for the breeding industry. 相似文献14.

Insect fragments in commercial wheat flour are a major concern to the milling industry because consumers expect high quality and wholesome products at the retail level. Thus, the US Food and Drug Administration (FDA) has established a defect action level of 75 insect fragments per 50 g of flour. Millers routinely test their wheat flour to comply with this federal requirement and to deliver sound flour to their consumers. The current standard flotation method for detecting fragments in flour is expensive and labor intensive. Therefore, we examined the possible use of a rapid, near-infrared spectroscopy (NIRS) method for detecting insect fragments in wheat flour. We also compared the sensitivity and accuracy of the NIRS method with that of the current standard flotation method. Fragment counts with both techniques were significantly correlated with the actual number of fragments present in flour samples. However, the flotation method was more sensitive than the NIRS method with fragment counts below the FDA defect action level. We were unable to predict whether the number of fragments in a sample exceeded the FDA action level with our NIRS instrumentation. However, we were able to predict accurately whether flour samples contained less than or more than 130 fragments. Although current NIRS instruments are unable to detect insect fragments at the FDA action level, this method should be re-examined in the future because NIRS technology is rapidly improving. 相似文献
