AtmoSAFE and Carmen van Waeyenberghe, director of the Belgian laboratory supplier Voor’t Labo and Memmert distributor, visited the quality laboratory of Alpro, the European market leader for soya-based food and drinks, in Wevelgem, Belgium.
Soya products are at the same time healthy and delicious. Furthermore Alpro soya drinks, desserts and yoghurt alternatives contain no cholesterol, animal fats, artificial preservatives, colourings and sweeteners. That means they are ideal for people that are allergic to milk, lactose intolerant or have problems controlling their cholesterol and weight. Seen on a broader scale, these plant-based food and drinks are good for people and planet. The soya bean, which was first grown in China more than three thousand years ago, is a white legume containing about 18 % oil and about 38 % protein. Therefore, many people see it as a worthy vegetarian alternative to meat, milk or eggs. Proteins are vital components of our body. Present in every one of the trillions of human cells, they perform many essential bodily functions. Without proteins, muscles would not develop and hairs would not grow on your head. Proteins determine skin texture, control hormonal processes and fight off infections. Since the body cannot store proteins, they must be supplied through the diet. However, not all proteins are the same. Essential for the human body are the amino acids. As a source of amino acids, the soya bean can compete with many animal sources of protein.
In food containing a lot of water and proteins, such as milk and soya drinks, germs are easily accumulated, especially when not refrigerated. Therefore, the Alpro soya drinks and soya desserts undergo Ultra Heat Treatment (UHT) in what is Europe’s largest and most modern production plant for soya food before sterile filling. During this ultra heat treatment, the products are sterilised for a short time at a temperature of more than +135 °C. To take no chances, the products undergo accelerated testing in a Memmert heating oven before leaving the production site. In accelerated testing samples from the production are exposed to high temperatures from +30 °C to +55 °C. After 3 and 5 days, the pH value is determined and the products are tested for spores - if any - in various analyses. The pH value is a crucial factor in food quality control. Many bacteria are most comfortable in a neutral environment (pH value between 6.6 to 7.5).
In the Alpro development laboratory, plant-based yoghurt variations are produced by fermentation with vegan yoghurt bacteria and adding fruit, and they are in no way inferior to their cow milk counterparts as far as taste is concerned. In the Wevelgem laboratory, the samples, which are placed on a Petri dish, are incubated at +25 °C in a Memmert cooled incubator IPP 400. After 3 or 5 days, the pH value is determined and a microbiological analysis performed. Eva Verbauwhede, laboratory teamleader at Alpro Wevelgem, especially appreciates the temperature stability, quick recovery time after opening the door, easy operation and clear parameter display of the Memmert cooled incubator IPP. Since space is very precious in any laboratory, the excellent relation between working space and space requirements is also a very positive feature.
Already the company founder Philippe Vandemoortele was fully convinced of the benefits of the soya bean to a healthy diet. Today, Alpro has production facilities in Belgium, The Netherlands, France and the UK. About its sustainability activities, the company states, that "grown from nature, our plant powered products are naturally better for the planet. But Alpro has never been content to simply stop there. We’re always looking to ways to be more sustainable and eco-friendly, and to lighten the footprint we leave behind us". That’s why the energy and resource-saving heating and cooling technology based on Peltier technology the Memmert cooled incubator IPP is equipped with, is perfectly in line with Alpro’s sustainability strategy.
AtmoSAFE would like to sincerely thank Alpro, especially laboratory teamleader Eva Verbauwhede and Carmen van Waeyenberghe, Voor'T Labo, for the time and effort they have invested in helping with the creation of this article.
About Alpro: Alpro is the European pioneer and market leader for soya-based drinks and food products (margarines, desserts and yoghurt, cream and meat alternatives) and is expanding its range with drinks made of almonds and hazelnuts.
