some clarifications.
Hello everyone. I couldn't help myself from replying so I had to register just so I could clarify some things.
re: duong thot not /đường thốt nốt
As I explained
here, it is Vietnamese for "palm sugar" and not necessarily coconut palm sugar. If your Asia palm sugar is from Thailand, look for " nam tan ma prao" / น้ำตาลมะพร้าว (Coco palm sugar). If it says "nam tan pep" /น้ำตาลปี๊บ it came from the sugar palm/arengga tree.
There are many types of palm trees with edible flower sap from which the sugar can be made. This is akin to sap from various maple trees, and as you may know, there are a number of them but only sap from sugar maple (Acer saccharum) and the black maple (Acer nigrum), are popular because of their high sugar content.
In the case of palm tree family, the most popular source for sap is the Palmyra palm (Borassus), also known as sugar palm because it can produce as much as twice the same amount of sap as Coconuts (Cocos nuciferas).
This is the general case in many Southeast Asian countries producing palm sugar but the Philippines is a late player in the "palm sugar" industry, the only palm sugar we produce in any commercial quantity are made from coconuts because we have very few sugar palm trees compared to our neighbors. (There's also the exotic pakaskas sugar made from the Nypa palm tree, but that is very rare and expensive. Not likely to be exported outside the country.)
So when you get your palm sugar and it only says "palm sugar" without any other qualifications, it's most likely to have been from a sugar palm tree (Borassus) or Arengga palm tree. Why? Because this make more sense economically for producers since they get more sap out of the tree, and hence more sugar. And the sad truth about some unscrupulous businessmen is if they can ride on the popularity of the "coco palm sugar" for their "palm sugars" and make a few extra bucks, then they will.
re PCA registration of Big Tree Farms or Sweet Tree brand
Metasequoia quoted that "Big Tree Farms" or "Sweet Tree" brand is certified by the Philippine Coconut Authority but that is not true. I've asked my contacts from PCA about this and there are no foreign companies that's registered with them.
Besides, Big Tree Farms operate from Indonesia and is outside the authority of the Philippine Coconut Authority agency.
I hope this helps clarify things up.
