Effect of Chemical Pre- Milling Treatments On the Physico-Chemical Properties of Mucuna Sloanei ‘Ukpo’

ABSTRACT This study examined the effects of chemical pre-milling treatment on the physico-chemical as well as pasting properties of Mucuna sloanei ‘ukpo’ flour. The seeds were treated with Distilled water, Citric Acid, Sodium bicarbonate, and Sodium Chloride solutions at various levels of concentration (1% 2.50%, 5% 7.5%, 10% w/v) before milling into flour. Proximate and functional properties of the flour were evaluated. Functional property analysis, of the Chemical treated flour showed t...

Effect of Oven Drying Temperatures in Preserving African Breadfruit (Trecuila Africana)

ABSTRACTThe study was designed to evaluate the effect of oven drying temperature in Preserving African Breadfruit (Trecuila africana). African breadfruit was sorted out, washed with clean water, parboiled for three mins to enable easy dehulling of the seed, dehulled using manual disc attraction mill, winowed and cleaned. The African breadfruit was subjected to different rates of drying temperature (50°c, 60°c and 70°c). Proximate, mineral, phytochemicals and sensory evaluation of th...

Traditional Fermentation And The Quality Of Balancotta Variety of Black Pepper {PIPER NIGRUM)

ABSTRACT A study was made of the effect on pepper quality of the traditional method of processing the "Balancotta" variety of Piper nigrum (black pepper). The study comparatively considered the microbiological quality, drying method, drying rate, colour and appearance, washing or cleaning method, prior to fermentation or heaping as well as an alternative method - heat treatment processing of the commodity. Using a solar dryer as a drying apparatus resulted in 9.8% moisture content of ...

QUALITY, SENSORY AND STORAGE ATTRIBUTES OF CHEESE PRODUCED FROM COWMILK SUPPLEMENTED WITH TIGERNUT AND COCONUT MILK

ABSTRACTCheese is a concentrated dairy product produced by acid or rennet curdling of milk, stirring and heating the curd, draining off the whey, collecting and pressing the curd. In this study, Cheese was made from cow milk supplemented with tigernut milk and coconut milk in the percentage ratio of 25:25:50; 25:50:25; 50:25:25; 75:25:0; 75:0:25% cow- tigernut milk-coconut milk (v/v). The unsupplemented cow milk cheese was used as control. The quality, shelf life and sensory attributes of the...

CHARACTERISATION OF MICROWAVED AND OVEN DRIED AERIAL YAM (Dioscorea bulbifera) STARCH

ABSTRACTNative Starch was extracted from Aerial yam (Dioscorea bulbifera). The starch extracted wasdried using oven (at 300C for 24 hours) and microwaved for (30, 45, 60 seconds). Starch obtainedusing different drying methods and conditions were analysed for their physicochemical, functionalproperties and pasting characteristics. Results obtained showed that amylose, amylopectin, colour,pH, bulk density, swelling power, least gelation capacity, oil absorption capacity, water absorptioncapacit...

Antimicrobial Activities of Oil Extracts of Piper Guineense and Xylopia Aethiopica on Some Microbial Pathogens of Food

ABSTRACT Oils extracted from the fruits of two Africa spices- Piper guineense and Xylopia aethiopica were evaluated for their antimicrobial activities using Escherichia coli, Salmonella sp, Aspergillus sp, Bacillus cereus, Penicillum commune and Rhizopus stolonifer as test isolates. Well-in-agar, disc diffusion and dilution susceptibility testing methods were used to assay for their antimicrobial properties. For the bacterial isolates the antimicro...

Comparative Of Production And Proximate Analysis Of Cake, Bread And Cookies Using Plantain Flour

Background of the studyThere is increased advocacy on the consumption of functional foods by World human nutrition due to different health problems related with food consumption such as diabetes and coronary heart diseases (WHO/FAO, 2003). Food professional/industries might face challenges of producing food products containing functional ingredients in order to meet the nutritional requirements of individuals with health challenges. This is because of the effect of added sugar and lipids...

Evaluation of the Emulsification properties of Hydroxypropylated Cassava Starch and its potential use in cocoa beverage

ABSTRACT Lecithin is used for applications in human food, animal feed, pharmaceuticals, paints, and other  industrial applications, but consistent importation of lecithin has a negative effect on foreign  exchange leading to devaluation of the naira. The need to explore locally available products such  as cassava starch as a possible substitute to the use of lecithin is paramount, hence, the reason for  this work. This research was carried out to evaluate the emulsification propertie...

Effect of Ocimum gratissimum in fresh tomato preservation

ABSTRACT The ability of leaf powder and leaf extract of Ocimum gratissimum plant to preserve tomatoes (Solanum lycopersicum) from early spoilage was investigated in  this study. Mixed cultures of tomatoes purchased from a  retail outlet in Ogun, Southwestern Nigeria, were treated with  the powder  and  some  with  the  leaf  extract  of  Ocimum  gratissimum  plant  and  observed  for preservation or spoilage ...

Thermophysical and Rheological properties of ogi(pap) made from sorghum

This study evaluated the thermo-physical and rheological properties of Ogi produced from varieties of sorghum with different soaking period (12, 24 and 36 hrs.). Sorghum grain steeped for 12, 24 and 36 hrs. was processed into Ogi making use of the traditional method and subsequently dried at 55oC. The Ogi powder obtained was analyzed for functional, thermo-physical, rheological properties and the consumer acceptability was also carried out. The results showed that the bulk density ranged from...

PROXIMATE AND SENSORY CHARACTERISTICS OF COOKIES FROM WHEAT AND TIGER NUT CHAFF FLOUR BLEND

ABSTRACTThe proximate and sensory characteristics of cookies from wheat and tiger nut chaff flour blend. Tigernut chaff was obtained, incorporated into wheat flour in the ratio (90:10, 80:20, 70:30, and 60:40). Cookies was produced from the blends using standard method. The cookie samples were analyzed for the proximate composition and sensory properties. The proximate composition showed the values for Protein, fat, fibre, ash, moisture, and carbohydrate ranged between 8.11 to 9.98, 7.59 to 9...
