Benefits Natural product which removes substantial quantities of haze forming material without affecting head retention Produces brighter worts, reducing the amount of finings required later Increases rate of fermentation and attenuation Increases filter runs Prolongs shelf life in small pack beers Reduces process time Tabletted for easy use Principle The active ingredient in PROTAFLOC TABLETS is a polysaccharide called carrageenan which is derived from seaweed. Carrageenan in solution is negatively charged, owing to the sulphate groups along the polysaccharide backbone. It is these charged sites which interact with wort proteins. In solution at temperatures above 65°C, the carrageenan has a random coil structure. As the wort cools the carrageenan takes a much more compact and ordered helical structure which is thought to drag the protein particles together to form aggregates. The aggregates, having a larger particle radius, settle faster. Kettle finings are added in the kettle only to allow the carrageenan to dissolve. Wort proteins react with carrageenan as the wort cools and settle as a cold break during fermentation to be removed along with the excess yeast. The removal of particles and protein from wort has been demonstrated by microscopic examination of pre-filtered beers and protein assay.

Not used yet but others have said they are OK. I use Irish Moss habitually, thought I might try these but they seem fussy.
