Introduction
Man’s food supply consists primarily of plants and animals and products derived from them. Microorganisms are naturally present in the soil, water, and air, and therefore exterior surfaces of plants and animals are contaminated with a variety of microorganisms. There is little specificity to this microflora since it reflects that of the environment in […]
Introduction
Consumers who read food labels are often surprised to see that there are added ‘flavours’ in most products. If, like many people, you think natural flavours are good and artificial flavours are bad, you need to know more about these additives.
Why flavours are added to processed foods
Flavours are used in processed food because overprocessing […]
No, eating over 100% of the Daily Value for a nutrient does not mean that you have to compensate by avoiding that nutrient on the following day. Your question is an excellent one, however, and I’d like to take the time to explain more fully how to interpret these percentages, including %DV.
In order to […]
The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer day?
Even early civilizations such as the Romans recognized that people “eat with their eyes” as well as their palates. Saffron and other spices […]
What is Gluten?

Gluten is the substance that gives breads and other grain products their shape, strength, and texture. But for the estimated 3 million […]
What are aflatoxins?
The aflatoxins are a group of chemically similar toxic fungal metabolites (mycotoxins) produced by certain moulds of the genus Aspergillus growing on a number of raw food commodities. Aflatoxins are highly toxic compounds and can cause both acute and chronic toxicity in humans and many other animals. Their importance was first established in 1960 […]
Internal Audits Create Opportunity for Food Organizations to Improve Systems, Processes
Audits are a planned, independent, and documented assessment to determine whether agreed-upon requirements are met, and the food industry relies on the audit function to provide safe food to their consumers.2 Many facilities organize their program into two categories: the external audit, performed by a third-party organization, […]
Introduction
HACCP is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. For successful implementation of a HACCP plan, management must be strongly committed to the HACCP concept. […]
OPEN VESSEL DIGESTION SYSTEM
Samples and reagents are heated on hot plates, sand baths or in microwave units in open beakers or flasks, made of glass, quartz, fluoroplastics (PTFE, PFA) or glassy carbon. Acid fumes are evaporated or (partially) condensed in reflux coolers. Max. Reaction temperature is the boiling point of the acid mixture at […]
The correct use of an HPLC column is extremely important for the life time of a column and therefore for the benefit of your HPLC analysis. The following text will give you some guidelines for the use, cleaning and storage of HPLC columns. These guidelines depend on the one hand on the nature of […]
