  1. The scientific literature says that Nandina species produces a chemical which breaks down to cyanide when ingested. Birds might die when they eat the berries, but children (and adults) are probably big enough to cope with the occasional accidental ingestion. Probably fine as long as you don't put it in your gob.
  2. That probably depends what the purpose of your lab is. If you are a commercial lab then having secret tests wouldn't particularly help your cause.
  3. Fortunately not - all the medical properties of the honey come from its physical and chemical composition. Irradiation is designed to kill live organisms present in the honey, like yeasts, moulds, bacteria, etc. Edit: Whoops I see Alistair has already answered this question.
  4. It's autoclaved and incinerated by an MPI-approved contractor.
  5. Sure. We get asked this occasionally. We are what's called a transitional facility, which means we're allowed to import honey from other countries for testing. We're allowed to do this because we have procedures for secure handling, storage, traceability, and destruction of honey, so that any nasties present aren't released to the environment. To achieve and maintain this status we have to be routinely audited by MPI to check we aren't doing things could compromise national biosecurity. Analysis of overseas honey makes up a small portion of our testing business. Much of that small portion is Australian, which is split between leptospermum-type honeys and other supposedly bioactive varities. These clients are requesting the usual suite of tests, like 3-in-1, C4, MPI5, etc.
  6. Although the plant is fairly prolific, it seems fairly rare to find the pollen in honey. Gorse pollen represents about 2% of the total pollen we've ever seen during pollen counts.
  7. This patent suggests using teatree oil and benzaldehyde (almond extract) as a topical bee repellent. You might want to research it a bit more before trying it though.
  8. Actually on second thought, this could probably be done by LC-IRMS, though I'm not sure who does that either.
  9. You tell me, does "amber", "light amber", "dark amber", and "extra dark amber" sound nice and lyrical?
  10. There is no direct test for total C3 sugar content, unfortunately. There are some tests offered by overseas labs for specific chemical markers found in C3 sugar syrups though.
  11. If it's not actually honey, does that mean they could put DHA and MGO in it? 🤔
  12. There are very few postdoc positions available in New Zealand. We have a pretty poor system for it really. Your best bet is probably to inquire at a Crown Research Institution (CRI) like Plant and Food Research who have a good apiculture research programme and see if they have any jobs available.
  13. I believe Terry and @Kate R went along. Terry said it was very well attended (100+ people?), with some good talks.
  14. Thanks for the info everyone. It seems like lots of people are using the a 2:1 concentration (67 brix). What about the type of sugar? White sugar versus inverted, corn syrup, etc? How many of you are heating to dissolve it?
