Moisture Control during Health Food Processing

Moisture Control during Health Food Processing

In processing powdery foods especially health foods like juice concentrates, protein supplements, soup powders, milk powders, jaggery powder, wood apple powder etc. the presence of moisture in the surrounding air can cause lumping or caking causing the tiny particles to stick or cluster together and inhibiting their free flow during processing. In addition, the presence of moisture in the air may interfere with the operation of the processing machine and obstruct the free and easy movement of the food stuff. It creates doubt and wrong perception in the mind of your end customer once the final product reaches to him, which can ultimately affect your Brand Loyalty and Value.

Moisture menace affecting quality of Nutraceuticals

Another vital part of health food are nutraceuticals. Nutraceuticals is a wide term used to describe any product derived from food sources that provides extra health benefits in addition to the basic nutritional value found in foods. Products typically claim to prevent chronic diseases, improve health, delay the aging process, and increase life expectancy. Nutraceuticals can be in the form of tablets, capsules and powder. Many nutraceuticals powders (like herbal extracts, effervescents and proteins) are extremely hygroscopic. This leads to the clustering and clogging of the powder feed to the tableting press and to high speed two piece capsule filling machines.

Many granular and powdered health foods are transferred to packaging via high velocity air streams. This process is commonly referred to as pneumatic conveying or just airveying. For food handling, the efficiency of transporting powdered, granulated or flaked  materials by high velocity air streams is significantly improved by drying the air. Highly hygroscopic health food powders like wheat grass, whey powder, milk powder, soup powder, jaggery powder, protein supplements and wood apple powder make humidity control a crucial element of materials handling systems.

Obviously, if moisture affects the food and the machinery in this fashion, the solution to the problem lies in surrounding the processing and manufacturing area with dry air. Humidity control is being  considered as a important measure during health food processing. During packing, in many instances, low RH has to be maintained for proper moisture control.
