Spray drying is one of the well-established one-step processes of encapsulation technique to form micro
particles. The concentrated violet pigment produced from Chromobacterium violaceum UTM 5 was
encapsulated using Gum Arabic and spray dried under optimum conditions: atomizing air (1.15 kg/cm3),
temperature feed rate (30 C), air flow rate (60 m3/h), inlet (180 C) and outlet (85 C) temperatures to
produce violet powder. On further investigation, the encapsulated pigment exhibited greatest stability
during the entire storage period of 30 days at pH 7, temperature 25e60 C and under dark condition. The
violet powders produced were utilized in coloring food products, yogurt and jelly. Results confirmed
promising use of this healthy natural colorant in food industry. This is the first report on spray drying of
violet pigment from Chromobacterium violaceum and its potential for application in food items
