Beverage testing with the MQuant StripScan mobile app
20 Jul 2021pH and nitrate content are two of the key parameters used to measure the quality and safety of food and beverages. This article examines the use and efficiency of the MQuant StripScan mobile app to measure the pH of orange juice samples and nitrate concentration of mineral water samples.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.

Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.CalorimetryCalorimetry is a technique used to determine the heat released or absorbed in a chemical reaction. Calorimeters can be categorized into bomb calorimeters, constant pressure calorimeters, differential scanning calorimeters, isothermal titration calorimeters, X-ray microcalorimeters, heat-loss calorimeters, and high-energy particle calorimeters. The choice of calorimeter depends on the application.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Food AuthenticationFood authentication ensures that food products are accurately labeled and free from adulteration or misrepresentation. This is important for consumer safety, quality control, and regulatory compliance. Explore food authentication tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Food ContaminationFood contamination refers to the presence of harmful substances or pathogens in food, posing risks to human health. Contaminants can be biological, chemical, or physical, and their detection is crucial for ensuring food safety. Advanced testing methods like PCR, chromatography, and spectroscopy are used to identify contaminants in food products. Browse our peer-reviewed product directory to find the best solutions for food contamination detection, compare products, check reviews, and get pricing directly from manufacturers.Food QualityFood quality refers to the attributes of food that influence its safety, nutrition, and taste. Monitoring and ensuring food quality are essential in production to meet health regulations and consumer expectations. Techniques like spectroscopy, chromatography, and microbial testing are used to assess food properties and detect contaminants. Browse our peer-reviewed product directory to find food quality testing solutions; compare products, check reviews, and get pricing directly from manufacturers.Chemical Residues in FoodFood FraudFood adulteration refers to food when it has been has been altered unlawfully with the addition of another lower commodity food product to increase quantity. The 2013 European horsemeat scandal saw the adulteration of beef products with the addition of horse meat.
