Effect of substituting sugar with date palm pulp meal on the physicochemical, organoleptic and storage properties of bread
The effect of substituting granulated sugar with date palm fruit pulp meal (DPFPM) in bread production was evaluated. Date palm fruit pulp was oven dried (46°C, 8 h) and milled. Granulated sugar was substituted at 0, 25, 50, 75 and 100% with DPFPM in bread recipe and bread produced using straight dough bulk fermentation method. Proofing ability of the dough, oven spring, bread loaf weight, volume and...

Effect of fermentation on physico-chemical, textural properties and yoghurt bacteria in mango soy fortified yoghurt
Mango soy fortified yoghurt (MSFY) samples were prepared by using blends of 78.3% milk containing 3% fat, 14.5% soymilk containing 8.2% total solids and 7.2% mango pulp containing 18% total solids. The physico-chemical, textural properties and yoghurt bacteria counts of MSFY were analyzed at an interval of 30 min during fermentation upto 270 min. The fermentation time had a positive effect on acidity but a...

Toxicity of leaf powder of Lepidagathis alopecuroides to Nile tilapia Oreochromis niloticus Juveniles
Oreochromis niloticus juveniles (mean body weight, 13.99±0.38 g and length, 8.32±0.93 cm) were exposed in a daily renewal bioassay to different concentrations of Lepidagathis alopecuroides (0.00, 1.0, 1.5, 2.0, 2.5 and 3.0 mg/l), for 96 h to assess its toxicity. The opercular (obf), tail beat (obf) frequencies and mortalities were monitored during the exposure period. The...

Effects of some processing factors on the characteristics of stored groundnut milk extract
The purpose of this work was to investigate the influence of processing variables on some properties of stored groundnut milk extracts (GME). GMEs were prepared from fresh, roasted (170 °C, 25 min) and steeped (water, 20 min) groundnuts. The groundnuts were milled, sieved, the slurry boiled, homogenized, pasteurized and stored. The GMEs packaged in glass bottles, plastic bottles and low density...

Thiaminase properties in the fillet and liver of Tilapia zillii from Osinmo Reservoir: A comparative study
The thiaminase enzymes were partially purified and characterized from Tilapia zillii fillet (flesh) and liver using ammonium sulphate precipitation. The enzyme showed specific activities of 5.20 and 1.17 umol/min/mg of protein respectively for T. zillii fillet and liver. The enzymes exhibited a maximal activity at pH 5.0 and 7.0 for the liver and fillet, respectively. The Michealis...

Performance characteristics, biochemical and haematologcal profiles of broiler chickens fed synthetic and herbal methionine supplemented diets
This study was conducted to compare the efficacy of herbal methionine (HM) to synthetic methionine (SM) in broiler chickens. The herbal methionine (Meth-o-Tasr®) was supplied by lntas Pharmaceutical Limited, India. The HM and SM were added to standard diets at 0, 0.5, 1.0 and 1.5 kg/ton of finished feed and fed to 168 Arbor Acre broiler chickens. After seven days pre-experimental period, the birds were...
