Kappa-2 carrageenan: structure and performance of commercial extracts II. Performance in two simulated dairy applications

摘要

Extracts of two Chilean carrageenophytes, S. crispata and G. Skottsbergii, were prepared by tow industrial processes: a mild alkaline extraction with sodium hydroxide and a more vigorous alkaline extraction with lime. The resulting kappa-2 containing carrageenans were separated into gelling and non-gelling fractions by elaching with 2.5/100 KCl. The weeds were also separated into gametophytes and sporophytes which were extracted separately. C crispus was included in the study for comparison.
