Guava fruit has several vital vitamins, minerals, and antioxidant that play a pivotal role in the prevention of cancers, aging, and infections. Also fermented dairy products have several nutritional and health benefits. Six treatments of bio-Raybe milk were made from goat’s milk fortified with 5% sugar and 3, 6, 9, 12 and 15% guava pulp with using ABT-5 culture. Adding guava pulp to goat’s milk improved starter activity, decreased coagulation time and syneresis and increased curd tension and water holding capacity.
Guava Raybe milk had slight low acidity, fat and saturated fatty acids and higher carbohydrate, total solids, dietary fiber, ash, total protein, water soluble nitrogen, total volatile fatty acids, unsaturated fatty acids, oleic, linoleic, α-linolenic acids and antioxidant activity values as compared with control. Guava Raybe milk also had the highest numbers of Str. thermophillus, L. acidophilus and Bifidobacterium and the lowest loss of viability ratios. The recommended level of 107 cfu.g-1 of bifidobacteria as a probiotic was exceeded for various Raybe milk treatments and remained above 107 cfu g-1 until the end of storage. Adding 6 or 9% guava pulp to goat’s milk highly improved the sensory properties of Raybe milk.
