An indigenous product of the Amazon rainforests of Brazil, acai berries are known as super foods for their nutritional contents. They are packed with essential nutrients like antioxidants, proteins, fiber, essential fatty acids and carbohydrates. These elements are highly beneficial for the overall health of the body and if included in the regular diet one can keep a number of diseases at bay.
Although the acai berries are available in many forms like juices, health drinks, tablets and capsules, the purest form of the acai berries is the pulp of the fresh fruit. The acai berries are short-lived; which means they must be consumed quickly after being plucked from the trees. Due to its increasing importance the acai berry juice is being made available throughout the world, but for this it has to be processed in a certain way so as to protect its nutritional content.
Spray drying and freeze drying are the two techniques that are used to process the acai berries. Although freeze dried form of the acai berry is more nutritious than the spray dried form, it is ten times costly than the spray dried form. The process of freeze drying involves three steps which are: freezing, primary drying and secondary drying.
In this process the berries are first frozen to keep the natural contents intact and then are allowed to sublime. Here adequate amount of heat is allowed to pass through the berries to remove the water from them. So if one wants to benefit from the acai, the freeze dried form is the best. This powder is used to make juices, drinks and smoothies.
But before buying the powder one must ensure that it is 100% pure. Acai berries are not cheap and hence with the increase in demand, many companies mix it with other ingredients to bring the cost down. This is a compromise on quality. Hence care must be taken to purchase genuine acai and its supplements.
