چکیده
A multi-channel continuous-flow ana]yzer equipped with biosensing deyices was deyeloped for multicomponent measurement and its use in automating routine analysis was evaluated. Biosensing was achieyed by the aid of an immobilized enzyme reactor insta]led in the channel, and the channe] switching process for the sensing of a different compound was made by using a column-switching rotary valve. Another rotary yalve was used for auto-sampling. Both of the two rotary valves were interfaced to a system control}er and work conjugatively in a programmed manner. Signal subtraction between different channels was found to be more precise compared with the multi-channel flow-injection analysis method,

Effect of Substitution of Sugar by High Fructose Corn Syrup on the Physicochemical Properties of Bakery and Dairy Products: A Review
High fructose corn syrup (HFCS) is commonly found in soft drinks and juice beverages, as well as in many pre-packaged foods such as breakfast cereals, baked goods and dairy desserts. Historically, sucrose (table sugar) was primarily added to processed foods and beverages as the sweetening agent. In recent years, the use of HFCS has significantly increased in popularity due to its sweetness, abi...

Well test analysis of multi-layer reservoir comprises several parts. The first part concerns the estimation of parameters values and next considers finding an appropriate method to determine the unknown reservoir parameters. If the initial estimations are less accurate and weak, the final assessment may lead to incorrect results, which are totally different from the reality. Utilizing Automated...

BACKGROUND The importance of exchanging sucrose for artificial sweeteners on risk factors for developing diabetes and cardiovascular diseases is not yet clear. OBJECTIVE To investigate the effects of a diet high in sucrose versus a diet high in artificial sweeteners on fasting and postprandial metabolic profiles after 10 weeks. DESIGN Healthy overweight subjects were randomised to consume d...
متن کاملQA / QC of sugars using the Agilent Cary 630 ATR - FTIR analyzer Application note
Various manufacturers especially in the chemical, pharmaceutical and food industries employ sugars in their products. Sugars can be extracted from plant or microbial sources or they can be chemically synthesized. The majority of sugars are purchased as crystalline white powders and the most common examples are glucose, sucrose, lactose, fructose, maltose and xylitol. Protein-based sweeteners su...
