Abstract
ABSTRACT :
Sterilized flavoured milk is the one among the most popular dairy beverages of India. Flavoured milk is preferred by the children world wide because of its pleasing flavour. Use of artificial colours and flavours may harm the health of children or young who are the main consumers of flavoured milk. Hence, there is a need to develop flavoured milk with natural colours and flavours extracted from plants and herbs. These natural colours and flavours are not only nutritious but also carry some health benefits when consumed. In the present investigation the method of manufacture of sarsaparilla / cinnamon / cardamom herbal sterilized flavoured milk using three natural colour extracts from beetroot, carrot and turmeric was standardized. Satisfactory quality herbal sterilized flavoured milk can be prepared from 2% fat milk added with 9% sugar.
Satisfactory quality sterilized flavoured milk was prepared using herbal flavours and natural colours. The quality of sterilized cardamom flavoured milk was superior even to control and among the three colourants, carrot was most acceptable.
Sterilized cardamom flavoured milk with three added natural colours can be stored up to 180 days. Sterilized sarsaparilla flavoured milk with added three colour extract up to 135 days, while sterilized cinnamon flavoured milk added with three colours extracts was moderately acceptable up to 3 months at room temperature.
The cost of formulations of one liter sterilized sarsaparilla flavoured milk beetroot, carrot and turmeric colour extracts was Rs.15.66, 18.36, 16.73 respectively. Similarly the cost of sterilized cinnamon flavoured milk was Rs.14.83, 17.53, 15.33 for beetroot, carrot and turmeric colours added flavoured milks. The cost of sterilized cardamom flavoured milk was
Rs.13.79, 16.49, 14.59 for beetroot, carrot and turmeric added flavoured milks. The cost of production of herbal sterilized flavoured milks was found to be high against a cost of Rs.10.80 for control sterilized flavoured milk prepared using artificial colours and flavours. The high cost of sterilized herbal flavoured milks may not deter its consumption because of the nutritional and health advantage of herbal flavoured milks and changing trends of preferences of consumers for more natural products.
