The importance of mineral elements for humans, domestic animals and plants - A review

  Minerals are inorganic nutrients, usually required in small amounts from less than 1 to 2500 mg per day, depending on the mineral. As with vitamins and other essential food nutrients, mineral requirements vary with animal species. For example, humans and other vertebrates need large amounts of calcium for construction and maintenance of bone and normal function of nerves and muscles. Phosphorus is an...

Optimisation of raw tooke flour, vital gluten and water absorption in tooke/wheat composite bread: Effect of raw tooke flour and vital gluten on wheat flour physicochemical and dough rheological properties (Part I)

Raw Tooke Flour (RTF) is a generic, shelf stable flour from matooke (a cooking banana variety) targeting the baking industry. However, its lack of gluten has hampered development of RTF/wheat composite bread. It is thus necessary to optimize levels of substitution of RTF into wheat flour with vital gluten as a processing aid for improving rheological and baking properties. The specific objective of this study was to...

Optimisation of raw tooke flour, vital gluten and water absorption in tooke/wheat composite bread, using response surface methodology (Part II)

  The objective of this study was to optimise raw tooke flour-(RTF), vital gluten (VG) and water absorption (WA) with respect to bread-making quality and cost effectiveness of RTF/wheat composite flour. The hypothesis generated for this study was that optimal substitution of RTF and VG into wheat has no significant effect on baking quality of the resultant composite flour. A basic white...

Functional and sensory properties of wheat (Aestium triticium) and taro flour (Colocasia esculenta) composite bread

  Functional and sensory properties of wheat (Aestium triticium) and taro (colocasia esculenta) composite bread were investigated. Unblanched and blanched flour were produced from taro tubers. These were separately used to formulate composite flour blends with wheat flours in ratios of 70:30, 80:20 and 90:10. Functional properties, water absorption capacity (WAC), oil absorption capacity (OAC), packed bulk...

Effects of packaging material on the quality of “pupuru” flour during storage

  “Pupuru” is a fermented cassava product dried by smoking. This study, investigated the effects of packaging material on the quality of “pupuru” flour stored at ambient condition (30.5 ± 3°C; RH 76.5 ± 3%) for 24 weeks. Pupuru flour was packaged in polyvinyl chloride (CP), low density polyethylene (LDPE), high density polyethylene (HDPE) and polypropylene...

Production proximate analysis and shelf life studies of ready-to-eat rice and kilishi

  Accelerated shelf life studies (50 ± 2°C, 27 ± 2°C) were carried out on meal -ready-to-eat (RTE) rice and “Kilishi” which were prepared and packaged in aluminum foil and high density polyethylene (50 µm gauge). Chemical, microbiological and proximate analysis of the product was carried out to ascertain the quality and safety of the meal. Total microbial load of the...

Microbial quality of fruits and vegetables sold in Sango Ota, Nigeria

  Fresh fruits and vegetables promote good health but harbour a wide range of microbial contaminants. To assess the microbial quality of fruits and vegetables sold in Sango-Ota, 15 samples of different fruits and vegetables were purchased from three vendors. Samples were analyzed to study the density of microorganisms by standard plate count (SPC). Mean microbial load ranged from 1.3 x 106 –...
