Optimising functional ingredients for enhanced nutrition

摘要

Fluidised bed and spouted bed processes by Glatt offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned using spray granulation, agglomeration, microencapsulation and coating. The consumer demand for fortified products is constantly growing and has been well received by end users. The form in which health-promoting probiotics, dietary fibres or antioxidants are consumed depends on both the preferences and everyday habits of the individual: some prefer sports drinks, protein bars or enriched iced tea, whereas others favour more direct dosage forms, such as effervescent tablets, sachets or capsules. However, although the manufacturing processes associated with these products present numerous challenges, a universal requirement is that functional ingredients must be stable during storage, precisely dosed, dissolve quickly or have a depot effect. Key factors are excellent flow properties, the absence of dust and a precisely adjustable bulk density; they must neither lump nor separate.
