Matu-soybean deliveries to grain elevators was and rity group means for oil and protein concentration ranged from percentage points, respectively. In the 3 yr of the study, to g kg11and to g kg, respectively. Oil concentration15% of the samples were above average for both protein. It has high (38–45%) protein content as well as its high (20%) oil content. The bulk of the soybean crop is grown for oil production, with the high-protein defatted and "toasted" soy meal used as livestock feed. Soybeans are standardized under the U.S. Standards for Soybeans.

However, this is a great opportunity for soybean growers to know about the protein and oil content quality of their soybeans with this free program. Duplicate aliquots of each sample were analyzed for nitrogen content by a micro-Kjeldahl method, and protein was estimated as %N × for corn (Ewart, ) %N × for wheat and soybeans (Ewart, ; Tkachuk, ) and %N × for barley (Ewart, ).Crude fat (oil) was measured in duplicate as ether-extractable material on a Soxhlet apparatus.

INTRODUCTION. Soybean is a major source of high nutritional quality protein and oil [1], and its economic value can be deter- mined by seed protein and oil content. Protein in soy- bean seed ranges from to g/kg with a mean of g/kg, and oil ranges . points (a protein/oil ratio of ) and kg ha. Given that the ). Processors may not be able to derive the valuable genetic-based protein/oil exchange ratio of is smaller than the 48% soybean meal if the soybean seed has too low of a calorific-based oil/protein ratio, one might expect the remaining protein content. To. MANUAL OF SOY QUALITY ANALYSES U.S. SOYBEAN EXPORT COUNCIL A-1 A. INTRODUCTION. The use of soybean products in the feed and food industry has increased steadily over the past decades. Of the total world production of soybeans, more than 90% is directly used for animal consumption. Book II, Grain Grading Procedures, illustrates the step-by-step procedures needed to effectively and efficiently inspect grain in accordance with the Official United States Standards for Grain. Official inspection personnel and agricultural commodity graders licensed or authorized to inspect grain.

The solubility of the protein, expressed as a percentage, was calculated by dividing the protein content of the KOH-extracted solution by the prot ein content of the original soybean sample (%). The Protein Dispersibility Index assay is also based on the solubility of soybean protein [13]. For this test . Flax Seed Oil/ Flax Seed Meal/ Chia Seeds – What about flax seed oil? Flax seed meal (flax needs to be ground) or Chia seeds are well tolerated and supply a bonus of . driest of all of the regions, so protein and oil levels on an as‐is basis tended to increase the most in those regions. For Western Corn Belt soybeans, an as‐is composition of % protein and % oil is quite extraordinary for a region that generally produces low protein soybeans. INTERPRETATION OF SEED SIZE AND FOREIGN MATERIAL RESULTS. Protein The amount of protein in wheat determines how flour performs. It is also used for a trading specification. The wheat protein is quoted at % dry matter and most laboratories will test it using a near infrared (NIR) spectrometer calibrated against the reference method. In the reference method, a ground sample of wheat is burnt.
