Low fat yogurt requires the use of stabilisers to enhance the texture and creaminess of the product. The most common stabilisers used are: gelatine (100 - 250 bloom, 0.2 - 0.5%), pectin (0.05 – 0.20%), modified starch (0.5 – 2.0%), alginate (0.25 – 0.50%), agar (0.8 - 1.1%), carrageenan (0.05 – 0.20%) (Hui, 2007). Guar is also a commonly used stabiliser, however only specialised depolymerised guar is suitable for yogurt (otherwise depletion flocculation may occur).
