Organic Gardening will upgrade its login and registration system on
December 11. The new system is needed to support some of the major site
enhancements that we are currently developing. The new system is shared with
other Rodale sites, including Prevention, Men's Health, Runner's World and Women's Health.

asked questions related to the new system.
Wood rosin ester is approved for use as a direct food additive (21 CFR 172.735) for use in citrus oils that are added to beverages to increase the density of the citrus oil and to act as an emulsifier at a maximum level of 100 parts per million (i.e., for the same conditions of use that T&R proposes for gum rosin ester). Wood rosin ester also is approved for use as a direct food additive as a plasticizing agent in chewing gum (21 CFR 172.615) and for use as an indirect food additive in the manufacture of articles or components of articles intended for use in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food (21 CFR 178.3870).
It's been an ingredient in Orange soda for 25 years or longer.

I dunno either, but I have always been a label reader since I was a kid. I noticed that one day back in the 80's. I normally don't care for orange soda, but we were visiting some kinfolk and that's what they offered, so I gladly accepted it. I remember asking my Mom what ester of wood rosin was, but she didn't know either.

Wood rosin is usually from pine trees, the pitch is before it's heated, the rosin is after it's heated and the volatile elements of the pitch separate out. Wood rosen is used in lots of things and it's very handy, adhesives, paper, solder, soap, ink. But it's also chewing gum and citrus sodas. As I found this study there were several links to complaints the Minute Maid also uses it. And as the study shows below, it's put on the exterior of some citrus fruits. Depending on how they treat the rosin, the study below points out the resulting treated rosins are not the same and are "temporarily acceptable" and "not acceptable" in the last example.
"The Committee is of the opinion, that coatings made from partially hydrogenated wood rosin are "temporarily acceptable" as coatings for fresh citrus fruits at an application rate of 50 mg/kg fruit. "
"For coatings made from the pentaerythritol ester of wood rosins the Committee considers that these are *temporarily acceptable* for use on fresh citrus fruits at an application rate of 50 mg/kg fruit. "
The Committee is unable to evaluate the safety of rosin "modified by maleic anhydride and esterified with pentaerythritol" because of the grossly inadequate toxicological database and the uncertainty regarding the specification of this modified wood rosin. The Committee therefore considers this modified resin *unacceptable* for food use.
