?TBS/AFDC 4(293)CD3
0 Foreword
Edible almond oil is derived from the kernel of almond fruit and is widely used in the food industry.This
Tanzania standard lays down specifications aiming at ensuring the safety and quality of edible almond
oil produced or traded in the country for human consumption.
In preparation of this Tanzania standard considerable help was derived from:
CODEX STAN 210 -1999 (Amended 2015) Codex standard for named vegetable oils published by
Codex Alimentarius Commission
In reporting the results of a test or analysis made in accordance with this Tanzania Standard, if the
final value observed or calculated is to be rounded off, it shall be done in accordance with TZS 4.
1 Scope
This Tanzania Standard specifies the requirements, sampling and testing methods for almond oil
intended for human consumption.

3 Terms and definitions
For the purpose of this document, the following terms and definitions below shall apply:
3.1 edible oils
food stuffs which are composed of glycerides of fatty acids of vegetable, animal or marine origin which
is suitable for human consumption. They may contain small amounts of other lipids such as
phosphatides, of unsaponifiable constituents and of free fatty acids naturally present in the oil.
3.2 vegetable oil
any of a large group of oils that are esters of fatty acids and glycerol, obtained from the leaves, fruit, or
seeds of plants.
3.3 edible almond oil
edible oil derived from the kernel of almond fruit (Amygdalus communis L.).
3.4 virgin almond oil
almond oil obtained, without altering the nature of the oil, by mechanical procedures, for example,
expelling or pressing, and the application of heat only. It may have been purified by washing with
water, settling, filtering and centrifuging only.
3.5 refined almond oil
almond oil obtained, by mechanical procedures and/or solvent extraction and subjected to refining
processes?
