Use of differential scanning calorimetry to detect canola oil (Brassica napus L.) adulterated with lard stearin.
A study was conducted to detect and quantify lard stearin (LS) content in canola oil (CaO) using differential scanning calorimetry (DSC). Authentic samples of CaO were obtained from a reliable supplier and the adulterant LS were obtained through a fractional crystallization procedure as reported previously. Pure CaO samples spiked with LS in levels ranging from 5 to 15% (w/w) were analyzed usin...
متن کاملDifferential scanning calorimetry of bacteria.
Thermograms obtained by differential scanning calorimetry of a range of bacteria of different heat resistances were compared. Equations were derived to calculate the rate at which the numbers of viable organisms in a calorimeter decline as the temperature is raised at a constant rate. Vegetative bacteria scanned at 10 degrees C min-1 showed multi-peaked thermograms with four major peaks (denote...

Cereal Chem. 66(4):317-320 The thermal properties of whole grain milled rice and milled rice flour samples. Gelatinization enthalpies were about 40% greater in whole grain were investigated by differential scanning calorimetry. Thermal curves rice compared to rice flour for each variety. Heating rate studies conducted were obtained on representative long, medium, short, and very low amylose on ...
متن کاملDifferential scanning calorimetry of cytoplasmic aspartate transaminase.
Differential scanning calorimetry has been applied to study factors affecting the thermally induced denaturation of cytoplasmic aspartate aminotransferase, a dimeric pyridoxal enzyme. The consequences of binding of coenzyme and substrate derivatives to both the apo and holo forms of the enzyme were investigated and are interpreted in terms of the stabilization of the native form of the enzyme. ...
متن کاملEvaluation and Characterization of Free and Immobilized Acethylcholinesterase with Fluorescent Probe, Differential Scanning Calorimetry and Docking
Acetylcholinesterase (AChE) enzyme which catalyses the hydrolysis of choline esters, such as acetylcholine, is very important in nerve function. Previous structural studies showed the possible amyloid fibril formation on the AChE. Therefore it is important to understand interaction of ligands to prevent the formation of amyloid fibrils. The purpose of the present study was to char...
