Knusprige, goldgelbe Kürbiskerne, duftende Sonnenblumenkerne mit intensivem Aroma, zart karamellisierte Mandelblättchen oder tiefwürzig riechende Kaffeebohnen – all diese Produkte verdanken ihre einzigartigen sensorischen Eigenschaften einem präzise gesteuerten Röstvorgang. Obwohl hohe Temperaturen für die Entwicklung der gewünschten geschmacklichen und olfaktorischen Qualitäten unverzichtbar sind, können sie gleichzeitig zu einem irreparablen Verlust wertvoller Vitamine, Omega-3-Fettsäuren und phenolischer Verbindungen mit antioxidativer Wirkung führen. Wie lässt sich dieser Prozess daher so optimieren, dass man den vollen Genuss erleben kann, ohne unnötige Einbußen an Nährstoffgehalten in Kauf nehmen zu müssen?
What's a roast?
By definition, roasting is the exposure of a product to a high temperature, but below the melting temperature of the product. Usually, the process is carried out in a dry pan or in an oven, where the product is sprinkled on a layer of baking paper, e.g. sunflower seeds or pumpkin seeds. Under technological conditions the process usually takes place in three temperature variations: mild to 140 °C, strong to 150 °C to 200 °C and very strong to 300 °C.
Roasting of seeds loss of valuable nutrients
Unfortunately, due to the fact that the process is carried out using a very high temperature in the raw material, there are a number of changes in the chemical structure, which, on the one hand, reduce the consistency and appearance of the product in valuable nutrients, which is an important aspect for the consumer. The seeds processed are delicately brittle, aromatic and slightly brown in color. Unfortunately because of the process carried out with the use of very high-temperature raw materials, a series of chemical changes occurs, which on the other hand reduce the texture and look of a product in precious nutrients and contribute to the improvement of the nutrition of other ingredients.
Proper roasting of the tips
To do the roasting process properly, we need to keep in mind a few important elements that will ensure that we get a healthy product without any unnecessary loss of nutritional value. We start with the proper heating of the pan or pot. This is a very important element because the better the pan is heated the shorter we will roast the seeds, and consequently we will lose less nutrients.
Is that what we roast and what we use roasted products for?
They are a great addition to salads, desserts, or commonly eaten as part of a sheep breakfast. They are also often added to natural yogurt or peas, pumpkin seeds, nuts or legumes, almonds, almond nuts, coconut livers, and many other elements of oily plants. They're a great add-on to salad, dessert, or most commonly consumed as a breakfast sheep meal.
