Glycemic indices of processed unripe plantain (Musa paradisiaca) meals

   The glycemic response of processed unripe plantain (Musa paradisiaca) commonly consumed in Nigeria were assessed using sixty healthy subjects. The post-prandial serum glucose concentration over a period of 2 h were determined half hourly, after the ingestion of the test foods. Blood glucose curves were constructed to calculate the glycemic index of the test foods. The results revealed that the Glycemic...

Total lipid content, fatty acid and mineral compositions of muscles and liver in wild and farmed sea bass (Dicentrarchus labrax)

The fatty acid and mineral compositions in the dorsal and ventral muscles and liver of wild and farmed sea bass (Dicentrarchus labrax) were evaluated. The farmed animals showed a significant higher fat content (p < 0.05) than the wild ones, for all studied samples. The percentages of SFA and PUFA as well as the n-6/n-3 were higher (p < 0.05) in the muscle in wild compared with farmed sea bass. However, in liver,...

Frequent riots experienced in several cities have then raised the deep issue of food security. The purpose of this paper is to identify for the case of Senegal the major causes of food insecurity among rural households which are more affected, in particular farmers. An ordered...

Glycemic index of three common varieties of Bangladeshi rice in healthy subjects

       Rice is a major staple food in Asian countries and it is a rich source of carbohydrate. Since Glycemic Index (GI), Glycemic Load (GL) and Insulinemic Index (II) (three important measures of clinical concern in the management and prevention of diabetes and metabolic syndrome) vary from population to population, we have measured these parameters in healthy Bangladeshi subjects with 3...

Some nutrients and antinutrients contents of mango (Magnifera indica) seed

       Proximate composition, amino acid profile and antinutrients contents of mango seed were investigated. The results of proximate analysis show that mango seed contains (10.06 ± 0.12%) crude protein, (14.80 ± 0.13%) oil, (2.62 ± 0.02%) ash,  (2.40 ± 0.01%) crude fibre, 70.12 ± 1.34%) carbohydrate and energy content (453.92 ± 4.32 KJ/100 g). The...

Impact of cold storage and blending different lactations of cow’s milk on the quality of Domiati cheese

The present investigation studied the making of Domiati cheese from raw or pasteurized cow’s milk stored at 4 - 5°C for 24 or 48 h as well as the effect of mixing equal amounts of evening and morning milk with cold stored cow's milk on some properties of Domiati cheese. Domiati cheese made from cooled stored cow's milk, either raw or pasteurized, had lower yields, TS, fat, TN and higher acidity, salt,...

Iodine content of iodized salt available in retail outlets in Mthatha

This study assesses the iodine content variations according to physical structure of salt and the socioeconomic status (SES). The cross sectional iodometric titration was used to determine iodine in salt samples according to the legal requirements of 40 - 60 ppm. Salt brands were purchased in a representative number of shops in Mthatha, South Africa and 66 samples were analyzed. The legal requirement was present in 38%...

Perception of food quality in yams among some Nigerian farmers

Yam, a staple and ceremonial crop is intimately integrated into the socio-cultural, economic and religious customs of several West African communities. This study presents a qualitative investigation of the perception of food quality in yams by farmers. Food quality in the yam tuber is significant in determining its utilization (both at subsistence and industrial level) and acceptability of yam’s food products by...

Effect of maturity stage on protein fractionation, in vitro protein digestibility and anti-nutrition factors in pineapple (Ananas comosis) fruit grown in Southern Sudan

   The investigation shows that albumin, globulin and protein content increases with increase in the days of maturity stage. While glotulin and non-protein nitrogen decreases with increase in the days of maturity stage. The prolamine remains constant during the maturity. An in vitro protein digestibility improves by decreases in tannin and phytic acid with increase in the days of maturity stage because...

Effects of oil palm phenolics on tumor cells in vitro and in vivo

The effects of oil palm phenolics (OPP) on cell lines were demonstrated in this study. OPP dose-dependent studies in selected cell cultures showed that OPP inhibited the proliferation of mouse IgA-secreting myeloma (J558), estrogen-receptor-positive human breast adenocarcinoma (MCF7) and human lung carcinoma (A549) cells at all doses. However, OPP enhanced the proliferation of Madin Darby Canine Kidney (MDCK) and Aedes...
