TS never heard of Taiwan 黑心凤梨? Appear on newspaper for many years already leh why still got people fall for it?
I asked a China agent for farm produce before and we talked about preservation and chemicals used.
He told me the reason why pineapple or fruits have a black rotten core is because they are injected with enhancers to make it sweeter. The problem is not only that, it is because they injected too much, this most likely means it is above safety standards.
And all fruits or veggies, even if travelling interstate, almost all farmers he know of internationally will need to apply more or less some preservation to maintain freshness. As long as it doesn't leave residue it is considered fine by international standards. Only those that grow below the ground, tend to survive better without preservatives.
These Taiwan fruits and veggies are confirm heavily artificially enhanced.
Our SEA are the best area for such tropical fruits, don't know why people buy from Taiwan. The recent season for the damn cheap black dream and the giant red Thai mangoes are good.
But unfortunately, people likes to believe the more expensive = better. That's why we see almost only the poor tasting MSW and no more cheap kumpung durians that can taste so much better.
