MaterialsandMethods Infantfoodswereformulatedfrom blendsoftreatedAfricanyam beanandpearlmillet. Functionalproperties,pastingpropertiesandsensorypropertiesoftheblendswere studied.MilletandAfricanyam beanweresoakedseparatelyinwaterandallowedto fermentfor48hatroom temperature.Whileforsprouting,milletandafricanyam bean weresoakedfor12and24h,respectively,atroom temperatureandsoakedseedswere separatelysproutedfor48hasdescribedbyChikwenduetal.[2]andOkaforetal.[3] withslightmodification.Afterfermentationandsprouting,theseedswereoven-dried andthenmilledintoaflourof0.6mm size.Theflourswereformulatedtosix complementarydiets(A,B,C,D,E,andF)100%sproutedmilletflour;100%fermented milletflour;95% sproutedmilletflour&5% sproutedafricanyam beanflour;95% fermentedmilletflour&5%fermentedafricanyambeanflour;95%sproutedmilletflour &5% fermentedAfricanyam beanflour;95% fermentedmilletflour&5% sprouted african yam bean flourrespectively.Functionalproperties were determined as describedbyAOAC[4]andOnwuka[5].Pastingcharacteristicsweredeterminedwitha RapidViscoAnalyzer(RVA),New PortScientificRVA Super4Machinewithserial number2112582-S4AmadeinAustralia.Sensorypropertieswerealsodetermined.All evaluationtestswereconductedintriplicatesanddataobtainedweresubjectedtoone wayanalysisofvariance(ANOVA)anddifferencesamongthemeansweredetermined usingDuncanmultiplerangetest(DMRT).StatisticalPackageforServiceSolution (SPSS)Version23.0wasusedtoanalyzethedataandp<0.05wasconsideredtobe statisticallysignificant.
