Forage Quality Analysis And Control Of Wheat And Its Main Byproduct

Based on the 2011-2015 in the enterprises purchase of wheat, wheat powder and wheat flour as the main research object. Each nutrition index in the analysis of the calendar year of wheat and its by-product of test results and the distribution range, analyzed the sensory index of wheat bulk density, impurity, mildew, disease spot in grain and vomiting toxins the correlation between sex, wheat powder and wheat flour in the crude protein, crude ash content, wet gluten value, the correlation of the three. The results are as follows:Chapter 1: Analysis quality of wheat and the quality controlIn this experiment, the paper analyzes the feed enterprises in 2014-2015 after the purchase of 708 wheat samples, think at the time of feed enterprises purchasing wheat, sensory evaluation is very important, in preference to the physical and chemical index detection. Recommended enterprise established wheat procurement standard for: moisture 14.0% or less; Unit weight 750 g/L or higher; Impurities 1.0% or less; 6.0% or less of the admixture; The mildew grain for 1.0% or less. When the mildew grain rate of 0.4% or less, can need not test on the spot vomiting toxins; When the mildew grain rate is between 0.4% ~ 0.8% depending on the type or gibberellic mildew grain of how many, to check the vomiting toxins; When mildew rate between 0.8% ~ 0.8%, demand will check vomiting toxins.Chapter2: Analysis quality of wheat powder and the quality control.In this experiment, the feed enterprises in 2011-2015 purchase of 229 wheat powder samples were analyzed after recommend wheat powder purchase labeled: moisture 14% or less, winter can be raised to 15.0%; Crude protein 14.5% or higher; Gluten 20.0% or higher; It is advisable to crude ash control within 3.0%. When purchasing the ash content must be classified as grading index, as will be checked. Gluten value as the item will be checked to reflect wheat protein quality of powder, protein can be used as a nutritional indicators checking items, used to adjust the formula to useChapter3: Analysis quality of wheat flour and the quality control.The experiment, the feed enterprises in 2013-2015 purchase of 622 wheat powder samples were analyzed after recommended procurement standard for wheat flour: moisture 14% or less; Crude protein 14.0% or higher; Gluten 38.0% or greater(aquatic products used as binder) or gluten 30.0% or more(as a high-end livestock and poultry feed energy to improve raw material or general aquatic natural adhesive); Crude ash can be controlled within 1.6%.When purchasing high gluten wheat flour, wheat flour gluten content relatively crude ash index is more important...
