Pectinase Usage Rate

[Woolsocks]

Does anyone have a rule of thumb for how much pectinase to use when adding whole fruit to beer? Planning to add fruit to the mash and don't want to regret it when it's time to lauter or filter.

don't add pectinase to the fruit, don't add fruit to the mash. Hemi-cellulose is usually the problem with fruit...not pectin. Also, why add fruit to the mash? You'll leave good stuff behind and then you're going to BOIL your fruit juice....?
