Effect of processing on micronutrients (calcium, iron, vitamin A, and zinc) in maize, bambara groundnut, cowpea, cattle bone, roselle calyces, palm oil, Brachystegia eurycoma and Althernanthe

Healthy mature seeds of bambara groundnut (Voandzeia subterranea Thouars), cowpea (Vigna unguiculata), cattle bone, roselle calyces (Hibiscus sabdariffa), red palm oil, yellow maize (Zea mays), and “achi†(Brachystegia eurycoma), were purchased from Ogige market, Nsukka, Nigeria. Methods The processing methods was based on the methods of Uvere et al., (2010). Production of maize-bambara and maize-cowpea food blends  The maize, bambara groundnut and cowpea seeds were cleaned by win...

ANALYTICAL REAGENTS FOR THE SPECTOPHOTOMETRIC DETERMINATION OF CHROMIUM, TIN AND LEAD – A REVIEW

BACTERIOLOGICAL ANALYSIS OF WELL WATER IN NEW HAVEN, IN ENUGU URBAN AREA

ABSTRACT Samples of well water were collected from four (4) different wells  located in different parts of New Haven in Enugu urban area, for  bacteriological analysis. Total bacterial counts, using pour plate  method were carried out. Nutrient agar plates were used for  general bacterial count, while MacConkey agar plates were used  for total coliform count. The four different wells that were  examined showed different bacterial counts. A total of four  different bacteria were isolat...

THE MICROORGANISMS AND COMPOUNDS INFLUENCING THE ORGANOLEPTIC PROPERTIES OF UGBA (FERMENTED Pentaclethra macrophyllea BENTH SEEDS)

ABSTRACT Ugba is a delicacy popular among the Ibo ethnic group of Nigeria, made by the fermentation of boiled seeds of African oil bean (Pentaclethra macrophyllea Benth). The microorganisms and compounds influencing the organoleptice properties of ugba were studied. The pure cultures of these microorganisms isolated from (ugba) sample produced by traditional method, were used in singles and in combinations to ferment African oil bean shreds. The ugba so fermented were analyzed organoleptical...

FOOD CONSUMPTION PATTERN, LIFESTYLE AND BODY MASS INDEX OF MARKET WOMEN (A CASE STUDY OF IKOSI-ISHERI LOCAL GOVERNMENT AREA OFLAGOS STATE, NIGERIA)

ABSTRACT The study was carried out to assess the food consumption pattern, lifestyle and body mass index of market women in Ikosi-isheri local government area of Lagos state. One hundred and fifty respondents were selected from two markets using random sampling method. Data were collected using 24-hour dietary recall, diet history, anthropometric data such as height, weight and body mass index was also calculated. The data was analyzed by using descriptive analysis such as frequency and per...

EFFECTS OF YOYO BITTERS AND SWEDISH BITTERS ON THE ARYLESTERASE ACTIVITY IN VERY LOW DENSITY LIPOPROTEIN OF MALE ALBINO RATS

ABSTRACT In order to investigate the effects of Yoyo and Swedish bitters on arylesterase activity in very low density lipoprotein (VLDL), 40 male albino rats were divided into 6 groups; i, 3-week Yoyo bitters. ii, 3-week Swedish bitters. iii, 3-week control. iv, 6-week Yoyo bitters. v, 6-week Swedish bitters, vi, 6-week control. Daily weight of animals were determined and dosage of bitters corresponding to weight of each animal was administered. VLDL was isolated by a simple precipitation pr...

CONSUMER ACCEPTABILITY OF SPICED COMPOSITE BREAD

ABSTRACT This study was conducted primarily to evaluate the consumer acceptability of spiced composite bread. The socio-economic characteristics, spiced composite bread consumption pattern of the consumer and the purchase intent through the use of questionnaire were also determined using a structured questionnaire. The bread samples were evaluated in terms of appearance, taste, texture and overall liking using nine-point hedonic scale. Interestingly, over 95% of the consumers (N=200) rated s...

CHEMICAL/MINERAL COMPOSITIONS OF WATER EXTRACTS OF Hibiscus sabdariffa

ABSTRACT This work was carried out to investigate the chemical properties of the water extract of zobo (Hibiscus sabdariffa) drink using the modern atomic absorption spectrophotometer. Zobo drink is a popular drink in the Nigeria, especially in the northern part of Nigeria. The result of the analysis indicated that the drink is high in vital mineral nutrients required for the healthy growth by humans and for the proper metabolic processes to be adequately maintained. Zobo drink is high, as i...

CHLAMYDIA INFECTIONS, HOW TO CONTROL & ERADICATE IT

INTRODUCTIONChlamydiae are small gram-negative obligate intracellular microorganisms that preferentially infect squamocolumnar epithelial cell (www. Google. Com.2010). Chlamydia is the most prevalent sexually transmitted disease resulting in urethritis, with frequencies exceeding those of Neisseria gonorrhoeae. In the United State for instance, roughly four million cases are reported annually mostly occurring in men and women under the age of 25 (Barners, 1990). In Nigeria and indeed most ...

COMPARATIVE STUDY OF DISINFECTANT EFFICIENCY OF ETHANOL, BLEACH AND PHENOLICS AGAINST Pseudomonas aeruginosa and Staphylococcus aureus

ABSTRACT Ethanol, Bleach and Phenolics are three kinds of disinfectants which have been widely used in common laboratories.  In this study, a compared experiment on these three disinfectants efficiency was conducted against Staphylococcus aureus and Pseudomonas aeruginosa using agar hole diffusion method.  Different concentrations of bleach (1%, 2%, 3%, 4% and 5%) were used on both organisms.  Also (50%, 60%, 70%, 85% and 95%) of ethanol as well as (5%, 10%, 20%, 25%, and 30%) Phenolics w...

COPARATIVE ANALYSIS OF MICROBIAL LOAD OF RIVERS IN OHAJI EGBEMA LOCAL GOVERNMENT

ABSTRACT Ohaji Egbema, Imo State were studied over a period of  twelve months to determine the effects of detergent effluent discharges on the aspect of water quality of the river. Water samples from Points A, B and C were screened for microbiological analysis. The results revealed that the level of pollution varied depending on season and that the water quality was acceptable at the upstream (Point A) but became impaired at Points B and C, indicating significant pollution from detergent ef...
