Extrusion cooking as an attractive process for continuous food production has been extensively developed in recent years. The high temperature–short time extrusion cooking is used in the food industry to produce direct expanded products such as snack foods, breakfast cereals and pet foods (Miller, 1990; Moore, 1994; Rokey, 1994). Extrusion of food material results in starch gelatinization, dena...

Duck meat sausages were prepared using 10% beef fat (FDS) and 10% hydrated cereal flours including rice (RDS), wheat, corn, millet, and barley to replace fat. Control duck sausages (DS) were also prepared only with duck meat and duck meat plus 10% beef fat. Results showed that protein and fat contents significantly decreased and total expressible fluid reduced with the addition of cereal flours...

Extrusion cooking technology is commercially used in the fabrication of a variety of snack-type and ready-to-eat foods made from cereal grains. However, with the exception of soybean, pulses such as lentil, dr...

Bacterial exopolysaccharides produced by lactic acid bacteria are of increasing interest in the food industry, since they might enhance the technological and functional properties of some edible matrices. In this work, Pediococcus parvulus 2.6, which produces an O2-substituted (1,3)-β-d-glucan exopolysaccharide only synthesised by bacteria, was proposed as a starter culture for the production o...

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...

The reliable determination of soluble, insoluble and total dietary fibre in baked goods and cereal flours is an important issue for research, nutritional labelling and marketing. We compared total dietary fibre (TDF) contents of selected cereal based foods determined by AOAC Method 991.43 and the new AOAC Method 2009.01. Fifteen bread and bakery products were included in the study. Our results ...

In order to utilize low economic value fish for human consumption there is a need for development of novel process for production of acceptable, shelf stable and ready to eat products. The preparation of extruded products from cereal-fish mince mixture is gaining more importance world over and as it offers many process variables to get acceptable high quality products. With more and more fish i...

The influence of four cereals namely, flours of wheat (Triticum aestivum L.), millet (Pennisetum glaucum L.), sorghum (Sorghum bicolor (L.)Moench) and maize (Zea mays L.)on the growth and development of T. castaneum was investigated at ambient tropical laboratory conditions of 30±3 ̊C and relative humidity of 75±5%. The antinutrients, mineral profile and proximate compositions of the four flour ...

Freshly harvested grains contain loads of thousand to million bacteria and mold spore per gram and the microbial contribution of cereal grains and flours to convenience foods is an important consideration from public health aspects and as a source of possible spoilage agents. Although the microbial load of cereal grains, meals, and flours may not constitute a spoilage problem by itself, the num...

Ochratoxin A is a mycotoxin produced mainly by Penicillium verrucosum and Aspergillus ochraceus. Although typically considered a cereal contaminant, it has also been detected in dried fruit, nuts, meat and derivatives. To estimate the quantity of ochratoxin A that might be ingested by Italian consumers from these foods, 211 cereal derivatives (flours and bakery products) were analysed by high-p...
