Abstract:
... Apple is one of the most important fruit grown and consumed in the temperate climate region. About 2% of the European population suffers from several allergenic reactions after consumption. Presence of 7 members of Mal d 1 gene family occurring in some apples was examined by PCR. The Mal d 1.01 and 1.02 genes could be detected from 91% and 79% of apple cultivars, respectively, due to the high degr ...

Abstract:
... Insects are alternative protein sources as nutritious novel food. However, there are some risks associated with the consumption of insects, even if rearing in controlled systems. Except for a recent EFSA opinion on the safety of insects as food, the European law is not conclusive regarding using insects as food products. Insects may be associated with microorganisms, but the prevalence of pathogen ...
