HPAE-PAD Speeds Analysis of Carbohydrates in Beverages & Milk

  
  
  
  
  
  
analysis of carbohydrates in apple cider

The ongoing challenge for food regulatory bodies is not just identifying food contamination problems but also making sure that product formulation and product quality meets regulatory standards and food manufacturers report any ingredients that might impact immune-and allergy-sensitive individuals. By the way, did you know that India has banned the import of milk and milk products from China until June 2015 due to concerns of contamination of melamine? And. you can read about our solutions on the analysis of melamine in pet food and milk (link to post) on this blog.

Ion Chromatography Pathogen Research Studies

  
  
  
  
  
  
pathogen analysis using ion chromatography

Here, I am pleased to present two ion chromatography research studies on two common human pathogens, namely Streptococcus pneumoniae (pictured here) and Mycobacterium tuberculosis, that have become increasingly dangerous to humans as a result of their resistance to antibiotics. Indeed, the World Health Organization's (WHO) first global report on antibiotic resistance (link to report) has revealed a worldwide threat to public health and as per their findings this is a serious threat and potentially may affect anyone, in any region of the world. Without an urgent action plan, the world may be en route to a post-antibiotic era, where antibiotics may become ineffective and common infections and minor injuries may have the ability to kill again.

In this very short blog post, I wanted to provide a link to a great resource, Advanstar Science's Chromatography and Sample Preparation Terminology Guide (link to page where you can click Register, fill out a brief form and then download the guide).

Chromatography Analysis of Additives & More in Beverages (II)

  
  
  
  
  
  
analysis of additives in beverage

After last month's post featuring chromatography applications for the analysis of sugars and artificial sweeteners in beverages (link to post), I am pleased to present two more application notebooks for the analysis of beverages, one for the analysis of carbonated beverages and the other for the analysis of additives in beverages.

It has been a few months since I featured any chromatography methods in botany research studies, and here, I am pleased to present several peer-reviewed articles feature the use of our ion chromatography systems and columns.

Chromatography Analysis of Sugars & Sweeteners in Beverages (I)

  
  
  
  
  
  
chromatography sugars in beverages

Have you been following the increasing efforts by various governments to regulate the amount of sugar in beverages or impose sugar taxes on sugary drinks in an effort to reduce sugar in food and beverage products? In one story, UK's chief medical officer told a committee of MPs that a sugar tax may have to be introduced to curb obesity rates (link to story) and in another story, the state of Illinois, in the USA, is considering a new tax on sugary beverages (link to story). By the way, a new study concluded that fruit juice has only a bit less fructose than sugary sodas (link to study).

Chromatography Solutions for Analysis of Milk

How this blog post on the chromatography analysis of milk and milk products came about was the featuring of the following two fascinating stories on our twitter stream and our Chromatography Solutions Facebook page on the topic:
  • Did you know that before refrigeration, people in Russia and Finland dropped live brown frogs into milk to keep it fresh? Moscow State University researchers discovered the science behind this odd custom; they found that amphibians' skin secretions are filled with peptides, which are antimicrobial compounds that are as effective against Salmonella and Staphylococcus bacteria as prescription antibiotics. 
  • The ability of geographically diverse Africans to digest milk has been linked to spread of cattle raising. Researchers found that the ability to digest milk became a selective force in the populations that raised cattle and consumed fresh cow, camel, or goat milk and identified three additional genetic variants with lactase persistence that had not been identified previously. By the way, it was the largest ever study of its kind in Africa.

In our 90-plus page Beverages Applications Notebook: Milk (downloadable PDF), we present applications for monitoring the compositional quality and safety of milk and milk products such as baby formula, lactose-free milk products, and milk for tracking contamination, adulteration, product consistency, and to ensure regulatory compliance.

Novel HPLC Approaches for Carbohydrate Analysis in Beverages & Food

  
  
  
  
  
  
Carbohydrate Analysis in Beverages & Food

Recently, we partnered with FoodProductionDaily.com to present a webinar on the use of universal Charged Aerosol Detection and selective pulsed amperometric detection for the direct determination of carbohydrates in complex food and beverage matrices. The advantages of two novel approaches, HPAE-PAD and HILIC-CAD was also discussed. The attendees asked several interesting questions on the types of detection and I thought they would make for good reading along with a couple of other resources.

I am pleased to feature a recently released ion chromatography application note that features two rapid and robust high-performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD) methods for the accurate determination of common sugars in acid-hydrolyzed wood samples for biofuel production.

chromatography software

I am pleased to present a series of five upcoming webinars on features in our using our award-winning chromatography data system (CDS) software (Thermo Scientific Dionex Chromeleon CDS software)! The goal of the webinars is to present the CDS software features that permit chromatographers to get the analysis right first time!
