short answer: no there isn't. you might write contains e.g. Beta-Carotin, but that's not really the same.

Ich glaube nicht, dass es eine ähnliche Kurzform gibt. Man kann aber "also" schreiben. "....also Beta-......"

ist die englische Entsprechung für u.a.

in gb ist die abkürzung "a.o.", = amongst others, weit verbreitet. Im notfalle ginge auch "et al." was eigentlich "usw", "und andere", bedeutet.

i.a. is preferable for a legal text.
a.o. is not common in AE.

KISS technique: just use "also".

:)

Many English language abbreviations are abbreviations of Latin phrases;'inter alia' is one of them and,as you say, means 'among other things', but in the example quoted 'also' seems the appropiate word if one is needed,you will see on some food products the simple words 'contains nuts'(some people have a nut allergy).
In more common use are e.g.,eg,ex.gr.=exempli gratia=for example//i.e.,ie=id est=that is
