Food-yeast Production from Wood-processing by Products
ثبت نشده
چکیده
Food yeast, which may be produced from wood carbohydrates and inorganic salts, is a source of protein, fats, and vitamins. The yeast contains about 50 percent of protein and 2 to 7 percent of fat, and is produced in yields of 40 to 50 percent of the carbohydrate from which it is grown. This yield represents a conversion factor of carbohydrates to protein of 4 or 5 to 1, as compared with a ratio of about 20 to 1 when carbohydrate is fed to pigs. The time of conversion is short and depends on the type of propagator.
