The carbohydrate fractions, protein and lipid contents of two cultivars of potato namely, Irish Cobbler and Red Pontiac, were altered quantitatively by Rhizopus oryzae during the 10-day incubation period. Glucose content increased during the incubation period for both healthy and inoculated tubers. Starch, maltose, sucrose, protein and lipid conten...

Previous research carried out in an animal model of retinoid-induced hypertriglyceridemia – rats fet a 13-cis retinoic acid (13cRA)-containing diet having casein as the protein source – has demonstrated that the complete replacement of dietary casein with soy protein isolate (SPI) can decrease the severity of this condition. In this study, the effe...

A technique for development of potato flour was standardized. Five products viz. cake, biscuit, weaning food, panjiri and ladoo were prepared incorporating potato flour, defatted soy flour and corn flour. Baking and roasting were the major processing techniques employed for the development of these products. Protein, ash and fat contents of potato ...

There are several mechanisms used by plants for survival in adverse environments such as drought, high temperature and salinity. The objective of this study was to evaluate the drought tolerance of tepary bean as a function of biochemical processes linked to isozyme synthesis and changes in enzymatic activity related to proline metabolism. Mature s...

Marmalade was produced from fluted pumpkin ( Telfairia occidentalis) fruit. The fruit was pulped, boiled and filtered to obtain pectin extract. The extract was boiled at 102 °C for 30 min with the pH and sugar levels adjusted to 3.2 and 68.5 °Brix, respectively. Fruit shreds were added towards the end of boiling. Results of analyses showed that the...

Mixtures of sweet potato flour and soy flour were made in a pilot mixer. They were moisturized with 18, 25, and 30% water and extruded in a single screw extruder at 80 rpm, using a die of 6mm. Extrusion temperature was maintained at 100 ± 3°C. Effects of adding soy flour into sweet potato flour, as well as variation in feed moisture on the composit...

Gari was processed from six different cassava cultivars TMS 3575, TMS 3044, hormone treated variety (HTV), TMS 30555, TMS 40944 and TMS 30572. Chemical analyses of the gari samples showed pH values of: 4.0, 4.0, 3.9, 3.6, 3.4, 3.6 and total titratable acidity of 0.99, 0.99, 0.98, 0.85, 0.96, 0.85 (% lactic acid) for TMS 3575, 3044, HTV, 30555, 3057...

The effects of sun-drying cowpea seeds for three hours on cement (CS), wood (WS), and corrugated iron sheet (CIS) surfaces and packaging separately in polyethene and jute bags were studied. Moisture-gain, and resistance to insect and mold damage were monitored monthly for six months, while proximate analyses on day zero and at the 6th month were co...
