Analysis of Food Additives Food Processing

Since food additives are widely used in food products, simultaneous analysis is essential to confirm proper use of them. Food processing takes a farmed product and turns it in to an edible, marketable product that may have a longer shelf life.
Efficient methods using GC-MS and LC-MS have been established for the simultaneous determination of several food additives Examples of these processes are baking, canning, fermenting, grilling, heating, hydrolysis, and roasting. During these
like flavor enhancers and sweeteners. With these simultaneous analysis methods, multiple compounds can be efficiently processes, undesirable and even toxic compounds can form. Or cross-contamination can occur from the big eight allergens of

Triple Quadrupole Mass Spectrometer Simultaneous Analysis of Sweeteners (LC-MS/MS)
LCMS-8060
A wide range of low-calorie sweeteners are often used in
foods. They are used together with sugars, and multiple
sweeteners are combined to regulate flavors. This example
shows the simultaneous analysis of 16 sweeteners. Good
linearity was obtained with a correlation coefficient of 0.997
or higher for all the compounds.
