This section GB/T 99695 Part of.

The partial modification of the use of ISO 5553. 1980 "Meat and meat products - Determination of polyphosphates." this part of ISO 5553. major changes compared to 1980 are as follows.

--- Standard structure and text were modified;

--- Rf value of TLC has been modified;

--- Extract preparation step in the amount of water has been modified;

--- References of ISO 3100 to GB/T 9695.19, because ISO 3100 sampling method does not apply to meat and meat products.

This Part replaces GB/T 9695.9-1988 "Meat and meat products - Determination of polyphosphates." this portion of the GB/T 9695.9-1988 compared to the main changes are as follows.

--- According to GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and writing rules" and GB/T 20001.4-2001 "Rules for drafting standards - Part 4. Chemical analysis methods," the original standard structural adjustment and text modifications.

--- Extract preparation step in the amount of water has been modified.
