Determination of polyphenol ‘pool’ in olive oil mill waste water using a tyrosinase biosensor operating in aqueous solution or in organic solvent

Abstract A method is described which will quantitatively determine 0.1 mg oxyphenisatin or the diacetate in various pharmaceutical preparations. After removal of interferences by organic solvent extractions from aqueous solution and partition column chromatography, the reaction of oxyphenisatin (diacetate) with silver nitrate in alcoholic sodium hydroxide solution produces a violet solution, which follows Beer’s law (1—15 μg per ml). The method was satisfactorily applied to the assay of commercial tablets, liquids, and powders with recoveries, as per cent found of declared, in the range 95—101%.

Spectrophotometric method using diphenylcarbazide as a colour developing reagent has been used to analyze the chromium content in tannery effluent located in Bara and Parsa districts of Nepal and Sirsiya River which is an ultimate drainage of these waste water streams. The adsorption of hexavalent chromium from aqueous solution onto formaldehyde treated sawdust and charcoal of sugarcane begasses has been investigated at various Cr(VI) concentrations of 5-40 mg/L and pH values. From the experimental observations, it has been found that chromium can be removed quantitatively at the equilibrium pH range of around 1 and the adsorption behavior revealed to follow Langmuir and Freundlich adsorption isotherms.Keywords : chromium, diphenylcarbazide, adsorption.DOI: 10.3126/jncs.v23i0.2102Journal of Nepal Chemical Society, Vol. 23, 2008/2009 Page; 93-101

With starting healthy consumption awareness in people throughout world, olive oil demand has increased and it is expected that this demand will increase day by day. As a result of increase in the demand for olive oil, the rise in amount of olive pomace that emerges after olive oil production is evident. The differences in olive oil production methods result in varied wastes in terms of property and quantity. Olive mill waste water and olive pomace possessing 35-40% moisture come out in 3-phase system while only olive pomace possessing 60-70% moisture comes out in 2-phase system. The quantity and pollution degree of waste water coming out in 3-phase system are considerably high from 2-phase system. Recycling of 2-phase olive pomace containing also olive mill waste water, which is highly harmful for environment and is generally discharged to nature without any treatment, is considerably important by processing. This review gives information about the necessity of drying of olive pomace and related studies with this subject.

Abstract Methods are presented for determining canthaxanthin as a 10% concentrate in beadlet form as such and in feed premixes and finished feeds. Canthaxanthin is liberated from the beadlets by hot aqueous solution and extracted into an organic solvent. In the case of feeds, separation from naturally occurring carotenoids in the extract is achieved by successive column and thin layer chromatography. Canthaxanthin in the final solution is isomerized to equilibrium with iodine and measured spectrophotometrically at 480±2 nm.
