:I web searched on " gelatin " together with " qsp " and eventually found some examples where qsp seemed to mean specific viscosity.

:So I'm guessing that qsp is being used to mean specific viscosity and the q is a mistake for eta, perhaps originating due to a character-set problem, or else an alternate symbol used if Greek letters are not available.

When scientific measurements are possible, the annealing point is a specific viscosity . " annealing point, AP the temperature corresponding to a rate of elongation of 0.0136 cm / min when measured by ASTM Method C 336, Test for Annealing Point and Strain Point of Glass by Fiber Elongation.

In a Google search on both " specific viscosity " and " qsp ", many of the results are papers that cannot be freely downloaded, but some hits-- for example this paper in PDF, the 10th hit when I did the search-- show qsp in Google's search synopsis while the actual document has an eta and sp.
