Safety of raspberry seeds in smoothies
It would be a bad idea to crush apple or cherry seeds while making smoothies or marmalades (due, apparently, to the presence of hydrogen cyanide).
If a raspberry smoothie is made in a 550W blender, the seeds survive unscathed (pictured below). They can be strained and discarded.
Does a super-blender (1300W-1500W) grind them? Does it become unsafe to ingest them?
Update
Normally an opinion, perhaps one that can be ascertained, is fine. But to confirm that there is no cyanide etc in some product, a reference would be nice. Or else a disclaimer for an empirical experiment you've been running (great teeth, powerful jaws) for years and have survived.
Best Answer
You can eat raspberries. You can chew them as much as you like, without dying. Your teeth (unless yours are suffering great defects) are perfectly capable of crushing the seeds.

Pits from stone fruits trees from the Prunus genus such as cherries, apricots and peaches can pose a risk of cyanide poisoning if crushed and ingested in significant amounts.

CYANOGENIC GLYCOSIDES - INFORMATION SHEET THE COMPOUNDS Cyanogenic glycosides or cyanoglycosides account for approximately 90% of the wider group of plant toxins known as cyanogens. The key characteristic of these toxins is cyanogenesis, the formation of free hydrogen cyanide, and is associated with cyanohydrins that have been stabilised by glycosylation (attachment of sugars) to form the cyanogenic glycosides. Examples of cyanogenic glycosides include linamarin from cassava and amygdalin from the seeds of stone fruit. The amount of cyanogenic glycosides in plants is usually reported as the level of releasable hydrogen cyanide. SOURCES The major edible plants in which cyanogenic glycosides occur are almonds, sorghum, cassava, lima beans, stone fruits and bamboo shoots.
Raspberries are from a different classification of plants that do not have elevated amounts of cyanogenic glycosides.

The raspberry (/?ræz?b?ri/) is the edible fruit of a multitude of plant species in the genus Rubus of the rose family, most of which are in the subgenus Idaeobatus; the name also applies to these plants themselves.
