This document is a draft of a specific GCC Standard Specification that was
distributed. This draft aims to respond to the opinions and notes contained in
the original specification and alleviate any concerns. As such, it is liable to
change and may not be considered a GCC Standard Specification until it has
been accredited by the GSO Board.

Preamble
The GCC Standardization Organization (GSO) is a regional organisation that
consists of the GCC Member States’ National Standards Bodies. One of its main
GCC Standard Specification GSO /2007
6
functions is to issue Gulf regulations relating to standards through specialised
technical committees (TCs).
The GSO has updated all the GCC Standardization Specifications under No GSO
1374/2002, "Edible Casein and Caseinates", as part of the technical committee
working programme No (TC 5), "The Gulf Technical Committee for
Specifications Relating to Food & Products from the Agricultural Sector". The
State of Kuwait has drafted this Specification.

3) Definitions
3.1 Edible Acid Casein: This is a milk product obtained from cross-linking,
centrifuging and dehydrating rennet with acidic precipitation that
exists in fat-free milk and/or other dairy products.
GCC Standard Specification GSO /2007
16
3.2 Edible Rennet Casein: The milk produced from cross-linking,
centrifuging and dehydrating fat-free milk and/or other dairy products.
Thrombus is attained through the interaction of rennet or other cheese
processing enzymes.
3.3 Edible Caseinates: The milk produced from the interaction of edible
acid caseinates or thrombus of the edible caseinates cheese with
neutralising agents, followed by dehydration.

a) Water percentage does not include the volume of water produced from
lactose crystallisation.
b) Protein percentage is 6.38×specified kjeldahl nitrogen.
c) Despite the fact that products may consist of hydrant lactose and
monohydric lactose, non-hydrant lactose is present which accounts for
95% of the 100 monohydric lactose particles.
