In this study, the potential of indigenous egg as functional ingredient in cake and chin chin was investigated. The proximate, colour and sensory characteristics of the pastries evaluated using standard methods. Indigenous eggs showed higher protein content (14.83%) than the exotic (13.61%) eggs. The same trend was observed for their fat contents. Ash and fibre contents of wheat flour and the eggs were generally low. The protein contents of cake (15.53%) and chin chin (10.75%) produced using indigenous chicken eggs were significantly (p ≤ .05) higher than samples produced using exotic eggs (Cake: 14.12%; Chin chin: 9.47%). In general, as exotic chicken eggs were replaced with indigenous eggs, the crust colour became lighter as measured by their L values. Overall acceptability of the cake samples were very similar for cakes produced from exotic (7.52) and indigenous chicken eggs (7.46) indicating that these two samples of cakes were moderately acceptable. Values obtained for sensory characteristics showed that indigenous eggs may only be suitable for making cakes with comparable quality to those made from exotic eggs. Future studies should make use of food additives to improve the taste of the chin-chin made using indigenous eggs. Keywords: Pastry, Indigenous, Exotic, Egg, Sensory properties

Soybean beverage, most common nutritious local beverage in Nigeria and in the world, is a high protein beverage used as a dairy milk substitute with the limited utilization due to natural or ambient conditions that serve as growth medium for microorganisms. Hence, it has a short shelf life. This study examines the shelf life of soybean beverage preserved with the ginger spice (dried at 70 ˚C, 80 ˚C, 90 ˚C and 100 ˚C, and 2 g and 4 g of fresh/wet ginger respectively) over 7-week period. The samples were (A: plain soybean beverage; B: 200 ml soybean beverage + 2 g of ginger dried at 100 ˚C; C: 200 ml soybean beverage + 2 g ginger dried at 90 ˚C; D: 200 ml soybean beverage + 2 g ginger dried at 80 ˚C; E: 200 ml soybean beverage + 2 g ginger dried at 70 ˚C; F: 200 ml soybean beverage + 2 g fresh ginger; and G: 200 ml soybean beverage + 4 g fresh ginger respectively). The proximate, pH, microbial and sensory analyses of samples ranged as follows: 87.35% - 90.83% for the moisture content; 0.58% - 0.65% ash content; 4.65% - 4.96% protein; 0.10%-0.26% fibre content; 2.06% - 2.98% crude fat and 1.68% - 4.17% carbohydrate, and pH values ranged from 6.2 - 6.5. Microbiological analysis over storage period showed that the control sample ranged from 0.4×106 -8.3×106 cfu/ml, and treated samples from 0.4×106 to 2.4×106 cfu/ml. Low values of the samples treated with dry ginger spice were preserved better than others, probably due to preservative and anti-microbial properties of the spice. Sensory evaluation, carried out by twenty-eight persons, showed that the sample E: (200 ml soymilk+ 2 g ginger dried at 70 ˚C) was most preferred (with respect to taste, aroma and overall acceptability), while there was a significant difference in the appearance of the samples.
