Research results

Our Company puts great emphasis on research proving high efficiency of sterilization by means of modern DET technology. Below we present some examples of sterilization results obtained for products of plant and animal origin.

Microbiological analysis

The microwave technology DET is a method of 100% efficiency eliminating resting spores of Alicyclobacillus acidoterrestris (AAT) which contribute to the worsening of final product quality.

The analysis carried out in the Institute of Agricultural and Food Biotechnology under supervision of Sylwia Skąpska, PhD Eng. shown the following temperature levels eliminating AAT resting spores: 135°C in case of apple concentrate and 120°C in case of aronia concentrate. The difference results from the different characteristics of aronia juice, which due to its high acidity and content of potentially bacteriostatic substances (like organic acids and phenolic substances) is an environment less “friendly” to AAT bacteria than apple juice.

Changes of the physicochemical parameters proved the ability of microwave DET technology to eliminate resting spores, among the others, from the concentrated juices.

Physicochemical and sensory assessment

Both apple and aronia concentrate has been sensory assessed using the specialized assessment panel. Analysis has been carried out on samples sterilized in maximum temperature and compared to the control sample. The result was no distinct difference of flavour and smell of the analyzed juice. The analysis has been done using triangle sensory test method.

Examination of sterilization using DET technology influence on the milk retentate after microfiltration

The examination has proven the efficiency of resting spores elimination in the retentate. Retentate sterilization process performed in microwave sterilizer has not caused deepening of sensory changes (heating aftertaste) despite the fact of sterilization temperature increase, which is a very favourable feature of this sterilization method.

Examination of sterilization using DET technology influence on cream

The examination has proven the efficiency of elimination of all microorganisms in cream. Cream sterilization process performed in microwave sterilizer has not caused negative sensory changes of sterilized creams which is a very favourable feature of this sterilization method. The method has caused neither free fat generation on sample surface nor fat generation.

DET sterilization influence on bioactive substances

Research of “The impact of honey blueberry processing on antioxidant properties and other selected parameters” supervised by Agnieszka Bartoszek, PhD Eng. has been carried out in the Department of Chemistry, Technology and Biotechnology of Food of the Chemical Faculty of Gdańsk University of Technology. The research was aimed at offering technology of berry processing, which would enable to preserve health related properties of final products to the largest possible extent. 

The results of the research led to the following conclusions:

"(...) Heating in Microwave Flow Sterilizer ENBIOJET is a very beneficial technological solution as it ensures microbiological quality of berry juices while preserving bioactive compounds at the same time. Also the fact that there are no transformations of saccharide fraction proves non-invasiveness of this technology. (...)"
