Resumen
Propolis is a natural product with great appeal to consumers and researchers due to its important functional properties. Nanofiltration was tested to concentrate the extract derived from propolis produced by Brazilian bees using a water- and an alcohol-based extract. A spiral membrane module with average molar mass cut-off around 150 to 300 g.mol-1 was used. The influence of pressure, temperature and tangential velocity on the permeate flux was evaluated and hysteresis in the membrane was analyzed. An average permeate flux around 12.0 l/h.m2 was obtained for the alcoholic solution and 25.0 l/h.m2 for the aqueous solution. The pressure was varied from 2 to 5.0 bar, providing variation directly proportional to the increase of permeate flux, and also to the increase of fouling, which reached 32% at 5.0 bar. The permeate flux also was directly proportional to the increase in temperature and tangential flow. Hysteresis was measured at 30 and 40 °C and demonstrated the elastic and reversible characteristic of the membrane. The process efficiency was measured by retention index of flavonoids and phenolic compounds. Around 99% of flavonoids in aqueous solution and 90% in ethanol solution were retained, and in the phenolic compounds, around 80 and 24% for the aqueous and the ethanol solutions respectively were retained. 30 1 166 172 Baby, A.R., Accelerated chemical stability data of O/W fluid emulsions containing the extract of Trichilia catigua Adr.
