Large Aloe Vera Freeze Drying Machine

Large Aloe Vera freeze drying machine

Aloe is an important source of functional components, including polysaccharides, organic acids, vitamins and minerals, which can be used in dietary foods and pharmaceutical products. Freeze drying, along with spray drying, constitute the basic drying technologies used for the increase of shelf-life of Aloe components. Aloe gel, the inner part of the plant's leaf, is the main source of these components, containing about 98% water. The purpose of this study is the investigation of the effect of drying in the preservation of Aloe's functional substances. The differentiations of drying upon the polysaccharides, the essential components of the gel, were studied by means of 1H Nuclear Magnetic Resonance (NMR) Spectrometry and Fourier Transformed Infrared Spectroscopy (FT-IR). The concentrations of inorganic constituents like K, Na, Ca, Mg were determined by atomic absorption spectrometry, Fe, Mn, Cu, Zn, Mb, Cr, Cd were determined by inductively coupled plasma atomic emission spectrometry (ICP/AES) and P content was determined by visible spectrometry, before and after drying. Gel was collected from the inner part of Aloe leaf and freeze dried. 

Concentration of polysaccharides was affected significantly from the drying process. On the other hand minerals concentration remained practically constant. Aloe gel contains a significant number of organic components, as well as minerals. The preservation and further use of these substances can be achieved by drying of Aloe gel. Nevertheless, drying process causes partial distraction of organic molecules and degradation of the produce Aloe powder.

NMR and FT-IR analyses showed that concentration of polysaccharides was affected, at some extent,from the drying process (air and vacuum drying), through deterioration of acemannan polysaccharides.On the other hand, minerals concentration remained practically constant.In conclusion, Aloe gel contains a significant number of organic components, as well as minerals. The preservation and further use of these substances can be achieved by drying of Aloe gel. Nevertheless,drying process causes partial distraction of organic molecules and degradation of the produce Aloe powder. Freeze-drying is the best way to keep everything.
