This product contains yeast extract, which is a natural raw material. Yeast generally contains a smaller proportion of glutamic acid, whereas extracts contain much higher levels. Yeast extracts are used as a natural flavoring and taste enhancer precisely because of their higher concentration of glutamic acid, but they are not synthetic glutamic acid/glutamate.
You can trust the Bio label; compared to conventional agriculture, the regulations here are much more strictly controlled, making the resulting quality of the food fairly transparent (it's pointless to focus on exceptions, which exist in all areas). When selecting food in relation to its quality, the most important aspect is visual assessment (degree of freshness, signs of rot or mold, degree of ripeness, etc.). For example, significantly unripe or rotting organic fruits or vegetables should not be prioritized over fresh and ripe products from conventional agriculture, because the risk of health implications from microbial contamination outweighs the potential drawbacks of consuming non-organic products.
It is generally presented that it's preferable to prioritize products grown under local conditions over those imported from abroad. The decisive factor here is the distance that food must travel from the producer to the customer, meaning, for example, that Austria as a neighboring country may not pose a problem compared to Spain or even overseas countries.
Heat treatment of tempeh before consumption is recommended for its NATURAL version. The reason is the active fermentation molds, which can cause digestive issues in sensitive individuals or potentially burden the immune system.
