Growth and sporulation of Clostridium perfringens type A in Duncan and Strong (DS) sporulation medium was investigated. A biphasic growth response was found to be dependent on starch concentration. Maximal levels of heat-resistant spores were formed at a starch concentration of 0.40%. Addition of glucose, maltose, or maltotriose to a sporulating culture resulted in an immediate turbidity increa...

Starch is a polymeric carbohydrate composed of glucose. As a source of energy, starch can be degraded by various amylolytic enzymes, including α-amylase. In a large-scale industry, starch processing cost is still expensive due to the requirement of high temperature during the gelatinization step. Therefore, α-amylase with raw starch digesting ability could decrease the energy cost by avoiding t...

the aim of this study was to establish and optimise a simplified method of halved grain culture, in order to utilise it to evaluate the ability of isolated sinks (developing wheat grains) in sucrose uptake and conversion (defined by sink strength) under unlimited source conditions. both sucrose uptake and starch synthesis increased linearly over the incubation periods used in this study. a ...

The increasing prevalence of coeliac disease (CD) and gluten-related disorders has led to increasing consumer demand for gluten-free products with quality characteristics similar to wheat bread. The replacement of gluten in cereal-based products remains a challenge for scientists, due to its unique role in network formation, which entraps air bubbles. When gluten is removed from a flour, starch...

Starch is the major source of carbohydrates in the human diet. Starch is present in many different fruits, vegetables, roots, and grains. Starch and starch derivatives are a nutritive, abundant, and economical food source. Starch can be consumed unprocessed in the form of raw fruits and vegetables or in the form of more shelf-stable processed foods. Food starches contribute to the characteristi...

Durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.], used in pasta, couscous, and flatbread production, is an important source of starch food products worldwide. The amylose portion of the starch forms resistant starch complexes that resist digestion and contribute to dietary fiber. Increasing the amount of amylose and resistant starch in wheat by mutating the STARCH BRANCHING ENZYME ...

For cost and health reasons, there has been increased interest recently in incorporation starch into imitation cheese formulations where the interaction between the added starch and the protein source (usually casein) has been shown to influence the rheological properties of the imitation cheese. Imitation cheese is widely used as an ingredient in prepared foods such as pizza, lasagne, cordon b...

Starch present in the endosperm of common wheat (Triticum aestivum L.) grains is an important source of carbohydrates worldwide. Starches with a greater proportion of amylose have increased levels of resistant starch, a dietary fiber that can provide human health benefits. Induced mutations in STARCH BRANCHING ENZYME II (SBEII) genes in wheat are associated with increased amylose and resistant ...
