  This study explored the nutrient and organoleptic potentials of wheat/ bambara groundnut based cookies. Bambara Groundnut (BG) (Voandeia Subterranean Thouars) and Wheat (W) (Triticum spp.) were purchased from Ogige market in Nsukka, Enugu state, Nigeria. Chemical composition, iron and zinc and phytochemical contents were analyzed using standard techniques. Wheat and bambara groundnut flours were blended in a ratio of 70:30 to provide 10% protein in cookies. The nutrient composition and sensory evaluation of the cookies were conducted. A panel of 38 judges and a 9-point hedonic scale were selected for use. Bambara groundnut complemented Wheat Cookies (BWC) contained 5.4% moisture, 9.85% protein, 19.7% fat and 10.32mg/100g iron which is much more than those of the 100% wheat based cookies. However, 100% wheat based cookies (WC) had six times ash and three times zinc content (1.2% and 23.28mg/100g) than those of the complemented (BWC) cookies. Nutrient composition of 100% wheat cookies (WC) could be improved when Bambara Groundnut (BG) blends it. The bambara groundnut-wheat cookies (BWC) were nutrient dense and culturally acceptable.

  Effects of household preservation were assessed in five vegetables commonly consumed in major tribes of Nigeria; Hibiscus esculentus, Corchorus olitorus, Lycopersicum esculentum, Talinum triangulare and Amaranthus caudatus. The selected vegetables were purchased from local markets without knowing their maturity age and time of harvest. The wholesomeness of the vegetables was based on physical examination of their texture and colour. The vegetables were divided into two portions. In the first portion, moisture and ascorbic acid were estimated. This served as the control. The second portion was sundried and their moisture and ascorbic acid compositions determined as well. Both moisture and ascorbic acid content of the vegetables were determined using standard methods. Sun-drying decreased ascorbic acid values between 68.1 and 86.7%. Moisture losses due to sun-drying ranged between 80.1 and 96.6%. The highest moisture and ascorbic acid losses were those of Talinum triangulare while Lycopersicum esculentum and Hibiscus esculentus had the least losses of moisture and ascorbic acid, respectively. Sundrying adversely affected ascorbic acid in these vegetables. Nutrition education is therefore necessary to minimize loss of ascorbic acid in vegetables due to household storage methods.

  This study evaluates the nutrient content and microbial quality of soymilk fortified with carrot powder. Carrots, soybeans, sugar and flavourings were bought from local retailers in Ogige main market, Nsukka in Enugu State, Nigeria. The fresh carrots were washed, scrapped, trimmed, sliced, sundried, grinded, packaged and stored in a labeled polythene bag. The soybean seeds were sorted, cleaned, washed, soaked for 18 hours, drained and blanched for 25 minutes at 89°C. The blanched beans were pulverized with hot water; the paste formed was diluted with water at 1:5 and then sieved to get the soymilk. The soymilk was cooked for 23 minutes at 87°C. Flavor agents and sugar were added, 20g each of carrot powder was added to 500ml and 600ml of soymilk respectively. Microbial loads of the samples were also determined. It revealed that proximate composition, vitamin and mineral contents of the fortified soymilk (CS2 and CS3) were higher than the plain soymilk (CS1). The total viable count of microbes of the samples CS1 and fortified soymilk (CS2 and CS3) were 4.85x10°CFU/mls, 6.25x101 CFU/mls and 6.80x101 CFU/mls, respectively. The result of the microbial counts revealed that the fortified soymilk (CS2 and CS3) contain higher microbial loads than the plain soymilk (CS1). Nutrition educators should encourage the public to use carrot powder-soymilk blend because of its source of micronutrient. Further researches should be done on the best way of reducing contamination in carrot powder.

  This study evaluated effectiveness of fresh and shade-dried Mucuna pruriens leaf extract in managing anaemia in adult male albino rats. Fresh leaves of Mucuna pruriens were harvested from Enugu-Ezike, Enugu state, Nigeria. The leaves were used to prepare fresh and shade-dried leaf extracts which were subjected to chemical analysis using standard analytical methods. Fifteen adult male albino rats weighing 180-250g, grouped into three groups (A, B and C) of five rats each were used for the study. All groups received rat chow and water ad-libitum. Group B and C received in addition, the fresh and shade-dried Mucuna pruriens leaf extracts respectively after anaemia induction. Blood samples were collected from the rats for determination of haemoglobin, PCV, RBC and WBC after a 5-day acclimatization, after anaemia induction and at the end of the study. Statistical Package for Social Sciences (SPSS) for windows version 18 was used to analyze the data obtained. p<0.05 was accepted as a cut-off for significant level. Fresh and shade-dried Mucuna pruriens leaf extracts contained iron (9.00±0.28 and 3.50±0.00 mg/100 mL), vitamin C (18.45±2.19 and 31.35±0.35 mg/100 mL) and pro-vitamin A (100.21±0.28 and 170.21±0.28 mg/100 mL). Haemoglobin, packed cell volume and white blood cell of rats fed fresh Mucuna pruriens leaf extract significantly (p<0.05) increased after treatment. Shade-dried Mucuna pruriens leaf extract significantly (p<0.05) increased red blood cell and white blood cell of the rats after treatment. Lymphocytes of the anaemic rats fed fresh and shade-dried Mucuna pruriens leaf extracts was significantly (p<0.05) increased whereas there was no significant (p>0.05) increase in the eosinophils of the anaemic rats.

  This study assessed effect of Iresine herbstii leaf extract and powder on biochemical profile of adult male albino Wistar rats. Twenty adult male albino Wistar rats divided into four groups of five rats each were used for the study. All the animals received rat-chow and water ad-libitum. Group A was the control. Groups B, C and D received in addition, fresh leaf extract, shade-dried leaf extract and shade-dried leaf powder, respectively. Blood samples were obtained from the rats for lipid profile, liver and kidney function tests. Data obtained were analyzed using Statistical Package for Social Sciences (SPSS) for windows version 18. p<0.05 was accepted as level of significance. Serum AST was significantly (p<0.05) increased in rats fed fresh leaf extract. There was a significant (p<0.05) reduction in serum ALT of rats fed shade-dried leaf extract and powder. However, serum ALT of rats fed fresh leaf extract was significantly (p<0.05) increased. Serum ACP was significantly (p<0.05) increased in the three treatment groups. Serum creatinine was significantly (p<0.05) increased in rats fed fresh leaf extract. Rats fed shade-dried leaf powder showed a significant (p<0.05) increase in serum urea after treatment. Serum urea of rats fed fresh leaf extract was slightly reduced. There was a significant (p<0.05) increase in total cholesterol of rats fed fresh leaf extract whereas rats fed shade-dried leaf powder showed a significant (p<0.05) decrease in total cholesterol. Serum LDL-C of three treatment groups were increased. However, this was only significant (p<0.05) in rats fed shade-dried leaf extract.
