Milk which is termed as the elixir of life, is the precursor of various relishing indigenous milk products throughout India that contributes maximum to the GDP of India.
With the current trend of value addition in food products, various research works are done to strengthen the business world in terms of sound marketing and customer care output.
Indigenous milk products have grabbed 50% of the market share in dairy sector with rapid urbanisation that quantitatively enhanced modern marketing. The quality of these products has improved substantially with the arrival of FSSAI. In the current scenario, manufacturers and consumers are in a combative mood to give and take the best product without compromising on quality.
Business economics may be a major concern for launching new and innovative indigenous milk products that may regulate the industry. Whatsoever the trend may be, in India with a predominance of vegan population, indigenous milk products are unparalleled to any food commodity even now. The business world must tap this potential treasure to have greater share in national economy.
The major indigenous milk products that rules the north Indian market are khoa, chhana, paneer, ghee and resultant sweets viz. kalakand, rasgulla, sitabhog, srikhand, sandesh and many more mouthwatering relishing sweets that have been recognised as significant contributors of important nutrients to the human diet. In India, there exist huge varieties of indigenous milk products, specific to the different regions, across the country. Most indigenous milk products are produced and sold loose by local halwais/ mithaiwalas (David, 2013). Several government and private organisations have been conducting research on the mechanised and hygienic production as well as distribution of the indigenous milk products. With the current upward trend in national and international health awareness among the consumers, the demand for functional, herbal, low fat food has increased. This has forced the food industry for launching indigenous dairy products in the market with acceptable sensory characteristics.
Overview – Major Indigenous Milk Products of North India
Paneer is a popular indigenous variety of soft cheese (David, 2013). Paneer is obtained by acid and heat coagulation of milk. Good quality paneer is characterised by a white colour, sweetish mildly acidic and nutty flavour, spongy body and a close knit structure. Paneer is highly nutritious since it retains about 90% fat and protein, 50% minerals and 10% lactose of the original milk. Paneer is nutritious and wholesome food. It provides one of the methods of conserving, preserving and prolonging shelf life of milk solids in highly concentrated form.
Functional Coconut Paneer
Coconut is an indispensible ingredient in many of the traditional cuisines of Southeast Asian countries including India. Coconut milk and fat is popular for its characteristic nutty flavour and nutritional content. Coconut milk is extracted from freshly grated coconut meat. Fat in coconut is similar to fat in mother’s milk and have similar nutritional effects. Coconut fat helps to maintain a healthy ratio of Omega-6 (w-6) and Omega-3 (w-3) fatty acids, when consumed as a part of a diet. The coconut paneer with 90:10 ratios of buffalo milk and coconut milk was found to be the best among others.
Peanut Paneer Prepared from the Admixture of Peanut (Arachis hypogaea L.) Milk and Skimmed Milk
Peanut and Peanut milk products have nutritional benefits because of their extreme richness in protein, minerals and essential fatty acids such as linoleic and oleic acids, which are considered to be highly valuable in human nutrition. Being free in cholesterol and lactose, peanut milk is also a suitable food for lactose-intolerant consumers, vegetarians and milk allergy patients. Peanut milk may be produced by soaking and grinding full fat raw peanuts with water to get a slurry, subject to filtration. Many ways of producing peanut milk have been done by various researchers (Benchat and Nail, 2006). Peanut paneer prepared from the admixture of peanut milk and skimmed milk 60:40 ratio is best.
Among the indigenous milk products, Kalakand occupies an important place and found to be attractive product amongst all the classes of consumers.

The granular mass is fused and held together in loosely compact body. The colour of Kalakand varies from off-white to light caramel colour. Being a whole milk concentrate, Kalakand is a good source of protein, mineral, energy giving fat and lactose. It is 4-6 times more nutritious in terms of per unit weight and calorific value. It can be made by two methods, i.e. from milk or from khoa. Kalakand made from milk slightly differs in respect of its manufacturing process to that of kalakand made from khoa.
Herbal Kalakand using Ashwagandha (Withania somnifera)
Ashwagandha (Withania somnifera) is rare and endangered plant and is widely used in Ayurvedic medicine and it is one of the ingredients in many formulations to increase energy, improve overall health and longevity and prevent disease.

Ashwagandha possesses immune modulatory anti-inflammatory, anti-tumour, antioxidant, anticancer properties and having many pharmacologically and medicinally important chemicals, that protect the cells from oxidative damage and disease (Sharma et al., 2011). They are effective in prevention and treatment of different kinds of cancer like colon cancer, lung cancer, blood cancer, breast cancer, prostate cancer, skin cancer, renal cancer, fibrosarcoma and pancreatic cancer (Singh et al., 2011). Herbal kalakand using 1% Ashwagandha is found to be the best.

Low Fat Dietetic Kalakand (Maltodextrin as Fat Replacer)
Maltodextrin is easily digestible carbohydrate made from natural corn starch. The starch is cooked and then acid or enzymes are used to break the starch into smaller polymers. Maltodextrin is defined as a product having dextrose equivalent (DE) less than 20. It is recognised as safe food ingredient. Maltodextrin is excellent solids builder for standard and low fat products. Maltodextrin can be used as a fat replacer (Dorp, 1995), texture modifier and bulking agent in dairy products. It provides only 4 calories/g of food. Kalakand prepared from skim milk and 3% maltodextrin was found to be the best in chemical and organoleptic parameters.

The curd (dahi) is partially strained through a muslin cloth to remove the whey and thus produce a solid mass called chakka, the basic ingredient for Shrikhand (Singh et. al., 2014).

This is the source of passive immunity achieved by the mother and is transferred to the baby (Thapa, 2005). Bovine colostrums have been used in many disorders in human beings. Five different types of immunoglulins viz. Ig A, Ig D, Ig E, Ig G and Ig M have been isolated from colostrum. Bovine colostrum contains 8-25%, Ig G whereas human colostrum contain2% IgG. These are protein molecules, which have important role in the body to fight against infection (Davidson et al.,1989).There is a need for utilisation of colostrum to prepare Steam Sandesh as it will enhance the therapeutic value of the product which otherwise go as waste.
