We compared cold (28°C) and hot (80°C) treatments to determine the effect ofextraction temperature on the yield and viscosity of the final product, using samples collected in BahiaTortugas, Baja California Sur (Mexico), in the summer of 1994. At 80°C we obtained a yield of 19.10% and a viscosity of 398 cps: at 28C the yield was 15.53% and the viscosity was 466 cps. Weconclude that hot extraction is more favourable, because the yield is statistically greater and theviscosity is the same. The effect of extraction time was also investigated in the hot process. usingsamples collected in Bahia Tortugas in the fall of 1990, to determine the minimum extraction time inwhich we can obtain high yield and quality of the final product. We tested times from 90 to I65 minutesat 80°C. In the temperature range tested, no significant difference was found between the yieldsor the viscosity. We conclude that the minimum extraction time is 90 minutes; however, to reach thefinal reaction point. the time must be extended to 120 minutes. 1996 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48022409 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4 Vol.22 |
