摘要：In this present work, ultrafiltration was applied for the purification of agro waste Greek red saffron. The agro waste saffron (before and after ultrafiltration) was used for the preparation of oil- in-water emulsions. Produced emulsions were examined for their viscosity, pH and conductivity during time. Also surface tension values of the aqueous and oily phase of the emulsions were measured. Saffron is known for its antioxidant and anti-solar properties. Anti-solar activity of saffron was evaluated by measuring the SPF value of the emulsion. UV-Vis measurements have shown an incredible increase of the absorption of saffron after ultrafiltration. The emulsions made with the purified saffron presented a better anti-solar activity and at the same time remarkably improvement of their antioxidant and antiaging properties giving a very promising alternative to the cosmetic industry.
