EFFECT OF SOME STABILIZERS ON TEXTURAL AND SENSORY CHARACTERISTICS OF YOGURT ICE-CREAM FROM SHEEPS MILK

Yogurt ice cream made of 6.5% sheep's milk fat and 11.5% of nonfat milk solids (MSNF) derived by 83% from sheeps milk contained decreased lactose and increased protein by approximately 20% and 25%, respectively, compared to the conventional product from cow's milk. Acidity of the final product was from pH 4.4 to 4.9. Stabilizers that were tried were xanthan gum, guar gum and a commercial stabilizer at concentrations 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5%. Based on determinations of physical qualities as well as on the sensory evaluation of the yogurt ice cream, xanthan gum gave optimum results at 0.2% concentration, guar gum at 0.3% while the commercial stabilizer was partially satisfactory up to 0.5% concentration.
