Abstract
Kunun zaki, home-prepared beverage relished by the Northern people of Nigeria as a refreshing drink was enriched with soybean and analyzed alongside commercially prepared Kunun zaki [Control] for proximate, mineral and vitamin C composition using the standard methods of analysis of AOAC. Sensory evaluation was carried out on the beverages substituted with soybean using 9-point hedonic scale. The protein content of the drinks ranged between 3.1- 8.1 g and carbohydrate 4.0-6.0 g/100 g for commercial Kunun Zaki preparations respectively (p<0.05). Similarly, carbohydrate value of soybean substituted KZ (6.0 ± 0.9 g) was found to be significantly. The fat content of soybean enriched and commercial Kunun zaki [18.0 g and 17.3 g/100 g respectively] were very close with no significant difference (P<0.05). Soybean enriched Kunun zaki showed increased macro and micronutrient content over that of commercially prepared one, and was also the most acceptable to the panelists. The beverage can be consumed by children and adult alike; hence the soybean enriched Kunun zaki drink production on commercial scale should be encouraged in every part of Nigeria as a means of improving nutrient intake of its consumers.
Highlights
Human beings cannot survive without water for a long period of time, as normal functioning of the body requires a continual supply of fluid in various forms including beverages
One of the samples was without addition of soybean (LKZ) while the other was enriched with soybean (SKZ) at the ratio of 2:1 (w/w) – millet grains/soybean
Prepared Kunnu zaki (CKZ) had the highest moisture content followed by Laboratory-prepared Kunnu zaki (LKZ)
Summary
Human beings cannot survive without water for a long period of time, as normal functioning of the body requires a continual supply of fluid in various forms including beverages. Beverages are food items that are consumed in liquid state, but have lower food values relative to milk and milk products. They are consumed either for their thirst quenching properties or for their stimulating effects [1]. They may exist as liquid or thin gruel preparation with high water content which supplies the body with water necessary to maintain health [2]. It is easier to consume a large volume of beverages than the same volume of water
