histamine on non-scombroid species

Dear List,

A good day to you all. It's my first time to post, having been recently accepted to join the group. I'm a  research assistant in our university and i hope you can help me on our problem. We are surrently working on the presence of histamine on some non-scombroid species of fish abundant in our area (sardines and bangus/milkfish). Sardines is primarily dried and sold in the market and the milkfish is used to produce value-added products (deboned, smoked, surimi-based products, etc.). I would like to inquire if there is a method of histamine analysis which is specific for dried products. We are currently using the AOAC method (fluorometric), but just recently we had acquired 1 unit of HPLC(it's quite difficult to ask for research fundings due to the limited budget allocated by the government), thus anyone has a method for Histamine Analysis using HPLC or could you refer me to some references where we could get a method.

My gratitude for your comments and suggestions.
