Title: Optimization of sunflower oil expression

Abstract

Models to predict input energy for sunflower oil extraction were developed for four seed types. Input energy was found to be the lowest in case of whole seed at low seed moisture content (up to 7%), whereas, at higher moisture content, coarsely ground seed required the minimum input energy. Maximum net energy was obtained for coarsely ground seed with 8% moisture content, heated to 35/sup 0/C and expressed at 28 MPa for 5.5 minutes.

  • The effects of expression conditions on sunflower oil recovery were studied. Samples of sunflower seed were selected at four levels; whole, dehulled, coarsely ground, and finely ground seed. In general, coarsely ground seed resulted in the highest oil recovery. Maximum oil yield for whole seed was obtained when a sample of seeds was expressed at 6 percent moisture, 42 MPa pressure for four minutes.

  • Four plastome mutations of type chlorina were crossed as female parents with variety Mayak. It was demonstrated that a three-phases hybridization led to the loss of chlorophyll defect in F/sub 1/. The suppression of plastic mutation is controlled by a single dominant gene. Four viable plastid mutants were used in the study-en: chlorina-1 (1-24), en:chlorina-3 (1-138), en:chlorina-5 (2-25), and en:chlorina-7 (2-43).
  • Effects of expression and pre-processing conditions on sunflower oil production in a static press were studied. Models to predict input energy for sunflower oil expression were developed for four seed types. Input energy was found to be the lowest for whole seed at low seed moisture content, whereas, at higher moisture content, coarsely ground seed required the lowest input energy. Maximum net energy was required in the case of ground seeds. In the case of whole seed, maximum net energy was required at the lowest moisture level. 9 references.
  • Sunflower oil is being researched as an extender or substitute for diesel fuel. Sunflower seed as a high oil content and an acre will produce about 60 gallons. Each Btu used to produce the seed and process sunflower oil will return about 5.78 Btu's. The price relationship per Btu of diesel to sunflower oil was 1:4.00 in 1979. This ratio declined to 1:1.80 in 1981. The on-farm processing cost for 4800 gallons varied from $2.82 to $4.33 per gallon for three press sizes analyzed. Operating these presses 300 days annually the cost per gallon varied from $1.74 to $2.99. 1more » figure, 8 tables.« less
