Sodium bicarbonate is a chemical compound with formula NaHCO3 belonging to salt group often found white powder crystals. Where content sodium remove stains on smokers. The purpose ...

Conclusion The above examples of the application of the concept of controlled proteolysis are very specific ones relating to a given substrate and enzyme system. The concept is, however, generally applicable in all proteolytic reactions where pH can be controlled. Under these circumstances DH is the parameter which determines the properties of the end products. This is of great industrial impdr...

Xylan is the second most abundant polysaccharide and a major component of plant cell wall. Cereal xylans contain large quantities of L-arabinose and are therefore, often referred to as arabinoxylans. Xylanases are hydrolytic enzymes, which randomly cleave the b-1,4 backbone of this complex plant cell wall polysaccharide. Different species of Aspergillus and Trichoderma produce these enzymes. Xy...

Quality driven design uses specified product qualities as a starting point for process design. By backward reasoning the required process conditions and processing system were found. In this work dynamic optimization was used as a tool to generate processing solutions for baking processes by calculating optimal operation strategies which give a basis for process and unit operation design. Two d...

The influence of three cooking methods (stewing, microwaving and Aluminium (Al) foil-baking) was evaluated on the content of intramuscular lipid and the composition of intramuscular fatty acids of Hyla rabbit. The percentage of intramuscular lipid in cooked-longissimus dorsi (LD) (dry weight %) were in the order mentioned below: microwaving > foil-baking > stewing. All treated samples showed de...

Baking quality of 11 winter wheat varieties was studied at the Jõgeva Plant Breeding Institute during 5 years (2005–2009). Protein content, farinograph absorption, dough stability time and loaf volume were examined in this study. The varieties were divided into clusters according to the average value of quality characteristics and coefficient of variation. Ada, Tarso, Portal, Ramiro had high pr...

A proficiency test to assess the capabilities of laboratories to determine melamine in a milk powder and a baking mix, representing starch-containing foods like bread and biscuits, was carried out in January 2009. The need for such an interlaboratory comparison arose from a health scare in China about melamine-tainted powdered milk in the second half of 2008. Laboratories in 31 countries, inclu...

Broa is a maize bread highly consumed and appreciated, especially in the north and central zones of Portugal. In the manufacturing of broa, maize flour and maize semolina might be used, besides other cereals such as wheat and rye. Considering the needs for genetically modified organism (GMO) traceability in highly processed foods, the aim of this work was to assess DNA degradation, DNA amplific...

The organic farmers use wider range of crop varieties than the conventional farming. Bread wheat is the most favorite and the most common food crop. The organic bread wheat is usually of worse technological quality. Therefore, it is supposed to be an attractive alternative to the hulled wheat species (einkorn, emmer wheat and spelt). Twenty-five hulled bread wheat varieties and control bread wh...
