| Abstract:
After an introduction to white sugar, sugar technology, beet extraction and thermophilic micro-organisms, three natural antibacterials stemming from the hop plant, the pine tree and from palm kernels are presented. These natural substances can be used in sugar factories instead of formaldehyde, which was recently classified as carcinogenic. Under thermophilic conditions Gram-positive micro-organisms are selected, which are sensitive to the natural antibacterials. However, even these micro-organisms may become insensitive to natural products after repeated application. In comparison to human health and the use of antibiotics, it is necessary to have different natural antibacterials, in order to meet most of the constraints, caused by micro-organisms in sugar factories. |
