Insoluble Particles

The addition of L-ascorbate or 2-mercaptoethanol to aged crambe seed meal tends to restore the fresh meal pattern of epi-progoitrin hydrolysis to nitriles instead of (R)-goitrin. Neither of these reducing agents has an effect on the breakdown of epi-progoitrin to goitrin by an insoluble particulate thioglucosidase from crambe meal. The addition of ferrous ion to the insoluble particles results in the conversion of epi-progoitrin to (2S)-1-cyano-2-hydroxy-3-butene instead of (R)-goitrin over a range from pH 3.9 to 6.7.

The objective of this research was to study on charcoal block production from eucalyptus bark using screw press unit. The physical and thermal properties of charcoal and factors affecting the testing units performance, which were mixing ratios by weight of eucalyptus bark charcoal: cassava starch: water content (1: 0.10: 0.75, 1: 0.15: 0.75 and 1: 0.20: 0.75) and screw pressing speeds (90, 105, 120 and 135 rpm) were studied. The optimum of screw press unit was screw pressing speed of 120-135 rpm and a mixing ratio by weight of eucalyptus bark charcoal: cassava starch: water content of 1: 0.15: 0.75. The test result at the feed rate of 140 kg/hr indicated that the machine had a capacity of 119.71-121.95 kg/hr, specific energy consumption of 12.33-12.73 W-hr/kg, charcoal block bulk density of 467.55 to 468.88 kg/m3, charcoal strength of 152.58 to 153.60 kPa and heating value of 21.95 MJ/kg for charcoal block moisture content of 7.46 % (w.b.)

Camelina Seed

Camelina seed was ground, solvent-extracted, and fed at levels of 0, 5, 10, 15, 20 and 25% of the diet to weanling mice. Licorice (0 and 0.025%) was tested as a cross-treatment to modify flavor. Levels up to 10% resulted in no adverse effects on growth of mice but each increase in level beyond 10% resulted m a significant (P <.05) reduction in gains and feed intakes. Licorice was ineffective.In a second experiment 20 to 22% of camelina meal was fed m all diets. Raw meal was compared with dry-heated meal (12 hours, 135 °C), autoclaved meal (15 min, 1.2 kg/cm2), steam-stripped (2 hours, 110 °C) and a casein–methionine–supplemented control diet. In each case, four myrosinase-source supplements were added: nil, crambe seed, rapeseed, and camelina seed (Crambe abyssinica Hochst., Brassica napus L., and Cameline sativa Crantz).Destruction of myrosinase by any method of heating resulted in significantly better feeding value of camelina meal, but steam stripping was superior to dry heating or autoclaving.It was concluded that camelina meal is probably superior to rapeseed and crambe meals, in that more than 10% of raw meal is tolerated in the diet before growth depression occurs. Near maximum growth was obtained with myrosinase-free diets containing about 20% meal. Growth depression that occurred at the higher levels of intake exceeded that which could be accounted for by the content of volatile isothiocyanates.
