Abstract
Two-step dry fractionation was employed to prepare the liquefied sheep tail oil at the pilot scale. Sheep tail oil was separated into fat residuals, crude oil, stearin A, stearin B, olein A, and olein B. The extracted rates for crude oil, olein A, and olein B were 66.7, 45.9, and 35.0%, respectively. The ratios of saturated/unsaturated fats in the crude oil, olein A fractions, and olein B fractions were 0.62, 0.63, and 0.60, respectively. The olein B was liquid at ambient temperature and its melting point was 5.32 °C. The iodine values of stearin samples were significantly decreased compared to the crude oil samples (P < 0.05). For the stearin fractions, the polymorphic form was mainly β’ form, and the solid fat content was significantly higher than the olein fractions (P < 0.05), which can be used to make the shortening product.
