Frequently Asked Questions
100% Pure, Not-from-Concentrate Juice
Our 100% pure, not-from-concentrate juices are squeezed directly from fresh fruits and vegetables. These juices taste natural and pure, just as if nature let the fruit ripen right in the juice. Pure, not-from-concentrate juices contain only the natural fruit flavours and the fruit’s own water that it formed and stored during its ripening period.
Juices from Concentrate
In line with our Voelkel quality policy and standards, we do not produce any juices made from concentrate. In a juice made from concentrate, the fruit’s own water is extracted from the juice. In addition, the taste-imparting flavour substances are separated from the juice. The concentrate is then reconstituted with demineralised water before being filled into bottles or containers. According to the German Fruit Juice Ordinance, the flavour does not have to come from the original fruit. At the end of the process, the bottle contains a “mixed” product that is sold to customers.
It is easy to identify juice from concentrate: for example, the label on a bottle of orange juice made from concentrate has to say “from orange juice concentrate”.
In the pasteurisation, or pasteurising, process, the product is heated to 60-90°C for a short period of time in order to destroy any microorganisms. The pasteurisation method is named after French biologist Louis Pasteur, who realised that flash (short time) heating destroys the majority of the microorganisms without significantly altering the properties of the product. In the case of food, it extends the shelf life.
Our natural organic juices are pasteurised in a special flash pasteurising process followed by immediate re-cooling. This method retains the fruit’s own original, pure taste, while preserving a large extent of the natural plant substances and nutrients, such as vitamins and minerals. Our pasteurised juices have a guaranteed minimum shelf life of between 8-24 months.
What does the term “true-to-seed” mean?
In biodynamic agriculture and plant breeding, true-to-seed varieties are developed exclusively through selection and are not genetically engineered. True-to-seed varieties pass on their characteristics and are able to propagate without restrictions. These types of plants, fruits and vegetables are the opposite of hybrids, which are produced by crossing two inbred lines. The seeds from hybrids are thus of no value to farmers, since they only guarantee a good crop yield for one generation and then lose their inbred, cultivated characteristics. The use of hybrids puts an end to replanting seeds from true-to-seed varieties and to the regional adaptation and improvement of the varieties. For all of these reasons, Voelkel makes it a priority to use true-to-seed varieties.
What are the advantages of true-to-seed varieties?
“Inherent qualities, exceptional vitality and character”: Picture-forming methods have proven that true-to-seed varieties have greater vitality than hybrids. True-to-seed varieties have a quantitatively higher proportion of the vegetable’s natural sugars, which contain a large share of disaccharides – an indication of good ripening capability. They are very flavourful and sweet. They also have a higher concentration of dry substances. Their nitrate level is often lower than that of hybrids. Moreover, they have a highly distinct, rich taste. Nevertheless, the majority of the agricultural sector uses hybrids, because they produce a uniform shape, large pieces of fruit and high crop yields.
Why did Voelkel decide to switch to true-to-seed varieties?
In the past, Voelkel already used a large proportion of true-to-seed varieties in its vegetable juices. Starting with the 2006 harvest, the family-owned company decided to exclusively use true-to-seed varieties in 4 of its products: carrot juice, beetroot juice, vegetable juice and sauerkraut juice.
Why doesn’t Voelkel use true-to-see varieties for all of its vegetable juices?
Our company has very long-term supply agreements and relationships with some of its vegetable farming partners. At Voelkel, our approach to fair trade relationships includes maintaining, supporting and cultivating these partnerships. Not all of our growers’ farms are suitable for growing true-to-seed varieties, since they produce a smaller crop yield as compared to hybrids.
