A study was conducted for four years to determine the effect of three soils at each of three Virginia locations on the protein and oil content of different soybean varieties. Soybeans were grown in plastic lined "pots'' fashioned by digging holes 48 inches deep and 14 inches in diameter. Root growth was restricted to the "pots" by plastic liners on the sides and copper mesh wire covering the bottom of each hole. Each soil was placed in the holes as near to its original position as possible. Under the conditions of this study, both soil type and location affected the oil and protein content of soybeans. Soil type affected protein percentage more than location but oil percentage was affected more by locations. Varieties responded differentially to soil type and location. Soybeans grown on Bertie sandy clay loam contained a higher protein and lower oil percentage than when grown on Sassafras or Davison soils. Soybeans grown on Davidson soil were lower in protein percentage than when grown on either Sassafras or Bertie soil. Location affected protein percentage in two out of four years and oil percentage each year. Soybeans grown on the southern-most location produced more oil and less protein than when produced at the two northern-most locations. / Master of Science

With the approval of menhaden oil pending, the food industry is trying to incorporate marine oils high in omega-3 fatty acids into food systems. The main problem obstructing its use as a food ingredient is fishy/painty flavors which occur with low levels of oxidation. The purpose of this study was to follow the formation of volatile compounds in menhaden/soybean oil blends and to correlate total volatiles with sensory odor scores. Specially Processed Menhaden Oil (SPMO) was supplied by Zapata Haynie Corporation (Reedville, VA). Blends of 0%, 10%, 20%, and 100% menhaden oil were stored for 15 weeks at 22 C, in the dark, with air in the headspace. Peroxide Value (PV) was measured. The amounts of pentane and total volatiles produced were measured using the Shimadzu static headspace attachment for the Shimadzu GC-9A capillary gas chromatograph. Total volatiles also were followed using direct injection volatile analysis. Retention times for selected volatiles were compared with those of known standards. Sensory analysis was completed using a modified version of the AOCS oil odor/flavor scorecard, with a panel of 12 trained judges. There was a significant increase in PY for each blend over the 15 week period (p<0.05). Pentane and total volatiles for the 0%, 10%, and 20% oils increased toward the end of the study but not significantly. Odor intensity scores did not increase over the 15 week period for any of the oils. The fifteen-week study period may not have been long enough for sufficient development of volatiles in the 0%, 10%, and 20% oils. The inclusion of the 100% menhaden oil altered the perceptions of the sensory panel since it had a much stronger fishy/painty odor. This caused the differences in the other oils to be overshadowed and poor correlations between sensory evaluation scores and PV and volatiles were obtained. Conditions responsible for the development of off-flavors in menhaden/soybean oil blends need further study before the commercial use of marine oils in food products is feasible. / Master of Science
