GST On Flavoured Curd

we are the manufacturer of dairy products with brand name"Creambell" and manufacturing of dairy products like curd, as per knowledge curd is exempted GST but we are also manufacturing flavored curd as mango curd and the process of mango curd is same such as normal but we are using only mango flavor approx 1% only and 85% milk rest of contentain I.e. 14% sugar, culture etc.
now the question is whether mango curd is taxable or exempted?
