Objectif
Highly concentrated aqueous carbohydrate solutions processed by the food industry like honey are metastable and tend to form crystals on storing. Forming and growth of crystals is hardly to control and cause fluctuations in product quality which are economic inefficient.
Fully crystallized systems need to be heated until the decrease in vicosity enables further processing such as filtration or filling. Avoiding that heating steps increase the quality natural honey (enzyme damaging etc.) and will lower energy costs.
The heating steps may be reduced or avoided by a elaborated and controled crystallization technique which lead to products with low yield stress caused by their physical structure. For processing (pumping, filling, etc.) such products need only to be warmed ip slightly.
Yhe influencing factors for crystallization such as temperature, pH, composition, age etc. will be investigated systematically. The influence of thermal and mechanical energy input on physical properties and product quality will be experimental tested.
Basic functional properties between process crystallization parameters and resulting product properties will be formulated.
The investigation will be carried out with natural honey of one defined provinience. The sample composition will widely be kept constent over the whole project time.
Natural products like honey gain increasing importance in worldwide trade with carbohydrates for the food industry. processes for controled crystallization honey and therefor quality improvement are innovate and will have high economic benfit for manufaturers in the EC.
