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...

PHYSICAL PROPERTIES OF CAKE FROM WHEAT FLOUR USING AVOCADO PASTE AS FAT REPLACER

ABSTRACT Avocado (Persea Americana) paste was utilized to substitute wheat (Triticum aestivum) flour as fat replacer in the production of cake. This study examined the effect of avocado paste substitutions at various proportions in production of cake. The proportions were 100% wheat flour, 95:5%, 90 :10%, 85 : 15%, 80 : 20%, 75 : 25% and 70 : 30% avocado paste. Colour analysis and texture of the cake was evaluated. Results shows L*, a* and b* value of the cakes ranged from 48.56-...

Chemical changes in African Star Apple (Chrysophyllum albidium) fruits

ABSTRACTThe study investigated the chemical changes inAfrican Star Apple (Chrysophyllum albidium) fruits prior to onset of rains and during the rainy season, with the aim of ascertainingits optimum consumption quality. The fruits were harvested from the School of Agriculture and Agricultural Technology, Federal University of Technology, Akure. Chemical analysis was carried out on the edible parts of the African star apple fruit(both the pulp and whitish seed coat). The result showed significa...

PHYSIOCHEMICAL AND SENSORY PROPERTIES OF COOKIES PRODUCED FROM WHEAT, SORGHUM AND DEFATTED COCONUT FLOUR BLENDS.

ABSTRACTCookies were produced from wheat, sorghum, and defatted coconut flour blends to determine their potentials in cookie manufacture. Eight Cookies formulations were produced and they were evaluated for their proximate, physical, mineral, colour and sensory properties. The result showed that the moisture content ranges from 7.10 to 10.89%, ash content ranges from 0.88 to 1.15%, protein content ranges from 9.18 to 12.25%, crude fat ranges from 9.59 to 11.00%, crude fibre ranges from  ...

PRODUCTION, CHARACTERIZATION AND UTILIZATION OF GUAVA FLAVOR CONCENTRATE

ABSTRACT This study was carried out to investigate the characterization and utilization of guava flavour concentrate produced from two guava cultivar using simple distillation technique for the flavor extraction. The physical properties of the flavor concentrate were determined and then utilized in the formulation of guava drinks with three different clouding agents (gum Arabic, garri aliquot and cheese-whey). The guava drink samples were also evaluated for different quality ...

COMPARATIVE STUDY OF SOME HEAVY METALS ACCUMULATION OF WATERMELON FOUND IN ZARIA AND KANO NIGERIA

The comparative study of some heavy metals accumulation of watermelon commonly consumed in Kano and Zaria environmental. The nutritional and mineral levels in watermelon fruits are generally important to support the nutritional requirement of man that is why its demand necessary to check the concentration of the ions it contains. Laboratory analysis like preparation of standard for test metals were carried out to check the levels of these heavy metals in Kano and Zaria watermelon fruit...

EFFECT OF ADDITION OF CITRIC ACID AND SODIUMBENZOATE ON THE KEEPING QUALITY OF SOYMILK

The greatest problem consumers encounter with soy milk remains its very short shelf life due to microbial activity. The combination of different preservation methods may just be the solution to the problem. The synergistic  effect of citric acid and sodium benzoate preservatives at various concentrations within their maximum permissible levels along with pasteurization, on the microbial keeping quality of home- made soy milk stored at ambient temperature was therefore, studied. This is with ...

Evaluation of four baking temperature regimes and their effects on shelf stability of bread loaves

The work was done to determine the effects of baking temperature on the proximate, micronutrient, microbial and sensory properties of bread. The breads were baked at four different temperatures of 190, 200, 210 and 220 0C for BT1, BT2, BT3 and BT4 respectively. The protein ranged from 10.53% to 12.42% and a significant (p < 0.05) difference existed between the samples. The crude fibre ranged from 1.50% to 1.70% and a significant difference existed between samples BT1, BT2, BT3 and BT4. The fa...
