I tried exporting this fragment using C-c C-e h, and could not replicate
this (org and html below). Maybe it would be revealing to try exporting
the org buffer directly using C-c C-e h (org-export-as-html), and seeing
if the problem occurs then with your setup?

I downloaded mma-mode just now from

http://www.itwm.fhg.de/as/asemployees/wichmann/mma.html

is that the same as yours?

,----[ C-h v mma-version RET ]
| mma-version is a variable defined in `mma.el'.

Here's my org

--8<---------------cut here---------------start------------->8---
#+title: mathematica example

* here's the block
#+begin_src mma
  absoluteFromGregorian[{year_Integer, month_Integer, day_Integer}] :=
    DateDifference[epoch, {year, month, day}]
  
  gregorianFromAbsolute[abs_Integer] := 
    DatePlus[epoch, abs]
#+end_src
and that was it
--8<---------------cut here---------------end--------------->8---

and here's the relevant bit of the html I got

--8<---------------cut here---------------start------------->8---
<pre class="src src-mma"><span style="color: #7fffd4; font-weight: 
bold;">absoluteFromGregorian</span>[{year_Integer, month_Integer, day_Integer}] 
:=
DateDifference[epoch, {year, month, day}]

<span style="color: #7fffd4; font-weight: 
bold;">gregorianFromAbsolute</span>[abs_Integer] := 
DatePlus[epoch, abs]
</pre>
--8<---------------cut here---------------end--------------->8---
