Processed Food

Hill Labs provides accredited methods for pesticides, heavy metals, nutritional information, allergen and microbiological testing in processed foods, including condiments such as herbs and spices.

Heavy Metal Testing

Food may become contaminated with heavy metals for many reasons. Many soil contaminants, such as heavy metals remain in biologically accessible states for extended periods of time, and are water-soluble, which means that they can bio-accumulate in fish, fruits, vegetables, shellfish and potentially humans. As such testing soil, water, fruits and vegetables for heavy metals is commonplace. Hill Labs has an extensive suite of heavy metal tests for use on everything from soil through to honey. Our technical notes will help guide you through what test may be right for your needs.

Testing products for allergens such as gluten, egg white and milk products Is important when wanting to ensure that a product conforms to its stated food labelling claims. Hill Labs offers a number of allergen tests for a variety of different products and drinks.

Understanding the nutritional information of food, especially processed food is a food labelling requirement. Nutritional panel testing includes getting an understanding of a product’s, energy, protein, fat (total and saturated), carbohydrate (total and sugars) and sodium. Assessing so many components within multi-component food groups can provide a number of analytical challenges, however Hill Labs team of expert analysts have made the process simple and convenient. Simply complete one of our test submission forms and sample and we will take care of the rest.

Hill News August 2024 - Update From Our MD, Dr Jonno Hill

This year our business turns 40, so it is natural that we take some time to reflect on our journey to date, and where we think we might be heading.  One of the things I am particularly proud of at the moment is the increasing attention we're paying to measuring and reducing our environmental footprint.  Running a business in a competitive market requires that many things are done well, and so we are always working hard at our 'business-as-usual' routine services, as well as a portfolio of projects aimed at expanding and improving our business.  As for any business, our key people generally have very little discretionary time, and there is always a list of things to do.  Spending time on environmental sustainability initiatives therefore requires deliberate thought and effort - time that needs to be carved out in an environment where time is of the essence.
