Abstract

Goat milk enriched naturally by Omega-3 through feeding with a mixture of carboxylate salt dry (MCSD), has a complete nutrition, but contrairely had a more distinctive smell goaty and high risk off flavour of rancidity. It made goat milk less desirable for consumption. Yoghurt is a fermented milk product that can be balanced the intestinal microflora between pathogens and beneficial bacteria. Cinnamon (Cinnamon burmanii) is a spices aromatic that rich in flavour and antioxidant. The addition of cinnamon extract in goat’s milk probiotic yoghurt aims to minimized the goaty smell and to maintain quality of product. This research has purpose to studied the effect of addition cinnamon extracts with different concentrations (3%, 4%, and 5%) on goat’s milk probiotic yoghurt characteristic include physical, chemical, microbiological and sensorial. The results showed that the addition of cinnamon extract influence the acidity (decreased pH value and increased total acid titrable) and sugar content of product, but there isn’t effect on viscosity, protein and fat content of yoghurt. Extract cinnamon addition at 4%-5% stimulated the growth of lactic acid bacteria to 0.7 log10 – 0.8 log10 CFU/ml. The hedonic-test showed that addition cinnamon extract wasn’t influence yoghurt acceptability, but the goaty flavour found less detectable in fermented product with addition of cinnamon extract becaused of the flavour resulted from fermentation process and volatile acid from cinnamon extract. It could be conclude that the fermentation and the addition of cinnamon extract increased the acceptability of goat’s milk probiotic yoghurt.
