Research has shown that newly hatched birds may be deficient in key digestive enzymes and that the immaturity of the digestive system may result in poor utilization of dietary nutrients. It has also been demonstrated that nutrient digestion rather than the ability to absorb nutrients seems to be the primary limiting factor. Therefore, dietary supplementation of enzymes not produced in sufficien...

Different starch properties may cause alterations in the foodstuff’s external appearance. However, modification processes starches are usually secretive. The use of chemically modified is regulated by international standards, which makes it important to identify its presence and type. Mid-infrared spectroscopy (MIR)-modified starches’ identification can be hindered excess glucose. This research...

This experiment utilised cassava (Manihot utillissima) and arrowroot (Maranta arunadinacea) wastes as the medium of propagation Saccharomyces cerevisiae to produce β-glucan. The amyloglucosidase hydrolysed waste, followed by fermentation in nitrogenous S. cerevisiae. β-glucan pellet was extracted using 2% NaOH alkaline solution at 90°C for 5 hours, a series centrifugation processes. highest glu...

High pressure treatment is well known as a sparing method for the preservation of beverages or food with low pH value, because it has only little effects on color, aromatic compounds and valuable substances like vitamins. Beer has a very sensitive composition and therefore high pressure treatment is an interesting preservation technique. This study consisted of three parts: The effect of high p...

The Hoechst dye fluorescence technique, which is used for the quantitative determination of DNA (12), requires high saline concentrations at neutral pH to reach maximal fluorescence of the DNA-dye complex and to render the DNA fully accessible to the dye by dissociating foreign molecules (3,12). In conventional assays, the DNA is alcohol-precipitated and then resuspended in buffer containing 2 ...

Microalgae, which accumulate considerable carbohydrates, are a potential source of glucose for biofuel fermentation. In this study, we investigated the enzymatic hydrolysis efficiency wet microalgal biomass compared with freeze-dried and oven-dried biomasses, both without an acidic pretreatment. With dilute sulfuric acid pretreatment followed by amy (α-amylase amyloglucosidase) cellulase hydrol...
