Total carotenoids (TC) were determined as a measure of total xanthophylls in grain flours and grits, by new validated spectrophotometric method based on A1cm1%-approach. The general analytical procedure is easily adjustable to different samples, the number of extraction steps depending on TC concentration in the sample. Basically, two methods have been suggested: the rapid one for low-TC sample...

BACKGROUND The nutritional quality of cassava complementary porridge was improved through extrusion cooking and compositing with either defatted or full fat soy flour (65:35 w/w), and product acceptability by mothers with children of the target population was evaluated. RESULTS The protein digestibility-corrected amino acid score (PDCAAS) of extrusion- and conventionally cooked composite porr...

In 1920 Johns and Finks’ reported a series of experiments whose results suggested the desirability of utilizing peanut flour as a supplement to wheat flour. In this article they state: “Bread made with a mixture of 25 parts of peanut flour and 75 parts of wheat flour 174 per cent extraction] furnished adequate proteins and water-soluble vitamine for normal growth.” These authors had previously ...

Concentration of 16 polycyclic aromatic hydrocarbons (PAHs) in eighteen baked bread samples using gas oven toasting were evaluated in this study. Samples were classified into the following categories: (1) bread baked from white wheat flour, (2) bread baked from brown wheat flour, and (3) sandwich bread baked from white wheat flour. Analysis was performed by GC-MS after Soxhlet extraction of the...

The burden of micronutrient malnutrition is very high in India. Food fortification is one of the most cost-effective and sustainable strategies to deliver micronutrients to large population groups. Global Alliance for Improved Nutrition (GAIN) is supporting large-scale, voluntary, staple food fortification in Rajasthan and Madhya Pradesh because of the high burden of malnutrition, availability ...

Edible mushrooms used as a protein-rich food may be an attractive alternative to conventional protein sources, while promoting its valorization. This work aimed obtain concentrate from Pleurotus ostreatus mushroom flour, characterization, and nutritional functional properties evaluation. Methodologies applied for extraction precipitation of were optimized - pH 4 12, respectively; flour-solvent ...

A validation study was performed on a multiresidue method for determination of pesticide residues in agricultural products according to the method validation guideline of the Ministry of Health, Labour and Welfare of Japan. FASRAC (Food Automatic Analytical Systems for Residual Agricultural Chemicals) automatically performs extraction of pesticide residues from agricultural products with aceton...

The current cross-sectional study with a comparison group was undertaken to investigate peak expiratory flow rate (PEFR) in flour mill workers and to study relationship between reduction in PEFR and age, smoking, exposure to grain dust and respiratory morbidity. The study included 286 flour mill workers and equal number of neighbourhood controls group-matched for age. PEFR was measured by using...

Wheat flour is an important source of nutrient and as such is widely consumed in most part of the world, as bread and other pastries. Due to its high consumption, the presence of heavy metal at high concentration would be a significant health risk. Based on the soil in which the wheat was grown and the milling technology employed in making the flour, the heavy metal content of wheat flour varie...
