Study On Quality Parameters And Enzymatic Activity Of Grain Mill Products Region In Transylvania

This paper aims at determining the main quality parameters of grain mill products in the Transylvania region, also studying and emphasizing the enzymatic activity of flour. Determination of quality characteristics of grain mill products entails establishing physical, chemical and sensory parameters and assessing them against the limits imposed by law. Analysis was performed on samples formed by mixing basic medium extracted from different batches. Incremental size, sampling tools, how to extract them, the training sample and laboratory environments, packaging and labeling of samples were performed according to STAS 1068 69. Determination of the fall (Falling Number), an empirical test that relies on the ability of endogenous ?-amylase to reduce viscosity of the treated warm flour suspension is used, large scale milling and bakery industry to predict and assess the Baking quality of flour. In sprouted wheat, characterised by a low Falling number, dextrin produced by the action of ?-amylase leads to a sticky bread core. Experiments suggest that the values fall turnover (FN) does not shrink in direct proportion to the percentage of germinating seeds. Amylolytic activity depends on the stage of sprouting of grains. Lack of ?-amylase activity can be corrected by adding malt grain ?-amylase or fungal ?-amylase.
