What does カピカ mean?

Question

I can't find this word in a dictionary.

It appears on a bag of rice I bought. The sentence is:

カピカ仕上げで、丁寧に磨いたきれいなお米です。

Is it a contraction of カピカピ, describing how the rice is dried out?

Answer 1

This describes a specific method of polishing rice.

From California's New Gold Rush - The New York Times

In one method, called kapika, polished rice is fine-sanded to produce a more lustrous finish
