Venkatesh1 and Akshaykumar2* 1(Dairy Technology), Dairy Science College, Bengaluru-24, India 2(Animal Science), ICAR-Krishi Vigyan Kendra, Bidar-585403, India *Corresponding author ABSTRACT In the present research an attempt was made to develop low fat Khoa. Khoa K e yw or ds is the traditional Milk based material for preparation of various sweets like Peda, Burfi, Kalakhand etc. Due to increased life style, disorders like Low fat khoa, cardio-vascular diseases, diabetes, and hypertension, the acceptability of Reconstituted skim milk and WPC calorie rich food like traditional products has been reduced. So, in order to meet demand for such target population and also for all the base material Article Info Khoa has been made with low fat by replacing WPC with 70 per cent Accepted: protein with has functionality of water binding, emulsification and gelation. 20 May 2020 Available Online: It is rich in essential amino acid and also has antibacterial, antifungal 10 June 2020 properties which can be exploited in dairy industry for manufacture of products. WPC at 5, 10, and 15 per cent was used among which 5 per cent was accepted. Introduction traditional dairy products particularly Khoa- based sweets have enormous market presence India ranks first in global milk production and tremendous consumer base in India and with milk production of 187.7 MT (NCAER, overseas as well. 2019), at growth rate of 6.62 per cent per year. The per capita availability of milk in Among traditional dairy products, heat India during 2019 was 394 g/day and by desiccated products have tremendous 2023-24, it is estimated to increase to 592 potential for value addition. Khoa, one of the g/day (NDDB, 2019). most important heat desiccated product, which utilizes 7.0 per cent of total milk Traditional dairy products are India’s largest production in India. About 1million tonnes of selling and most profitable segment in dairy Khoa is produced annually in India (Rasane et industry after liquid milk, accounting for al., 2015) and 520 billion Rupees market for about 50 per cent of milk utilization. Many Khoa based sweets with annual growth of 50 2661 Int.J.Curr.Microbiol.App.Sci (2020) 9(6): 2661-2666 billion INR.

According to National Council of Applied According to FSSR 2011, Khoa defined as Economic Research (NCAER) the current Khoya, by whatever variety of names it is carryover stock of Skim Milk Powder (SMP) sold such as Pindi, Danedar, Dhap, Mawa or is estimated at about 2 lakh tonnes, which is Kava, means the product obtained from cow unlikely to be absorbed until end of 2019. or buffalo or goat or sheep milk or milk solids Milk powder is obtained by partial removal of or a combination thereof by rapid drying.

Stainless steel sub-continent, a number of heat desiccated vessels of varying capacities and stainless milk confections are popular. These products steel stirrers were used at various stages of the are based on Khoa/Mawa, which is used as investigation. The vessels were washed by base material for sweets such as Peda, Burfi, using detergents and kept for air dry.
