6 Draft Sri Lanka Standard SPECIFICATION FOR PACKAGED COCONUT WATER FOREWORD This Standard was finalized by the Sectoral Committee on Food products and was authorized for adoption and publication as a Sri Lanka Standard by the Council of the Sri Lanka Standards Institution on. Use of coconut water as a tropical beverage is famous all over the world today. Coconut water is gaining popularity as a healthy drink. It is considered as an alternative beverage for rehydration after exercise-induced dehydration. Within the nut, coconut water is sterile and is free from microorganisms but when exposed to air or to the environment, the product is prone to microbial contamination and deterioration. Therefore this Standard specifies the microbiological limits as well as chemical and physical requirements for the packaged coconut water. This Standard is subject to the restrictions imposed under the Coconut Development Act No. 46 of 1971and regulations and Food Act No 26 of 1980 and the regulations framed there under. For the purpose of deciding whether a particular requirement of this Standard is complied with the final value, observed or calculated, expressing the results of a test or an analysis, shall be rounded off in accordance with SLS 102. The number if significant places to be retained in the rounded off value shall be the same as that of the specified value in this specification. In the formulation of this Standard the valuable assistance derived from the publications of the Philippine National Standards and Codex Alimentarius Commission is gratefully acknowledge. 1 SCOPE 1.1 This Standard prescribes the requirements, methods of sampling and test for packaged natural coconut water, which is offered for consumption. It only applies to coconut water which has been packaged in its natural state. 1.2 This Standard is not covered young coconut water. 2 REFERENCES SLS 143 Code of practice for general principles of food hygiene SLS 313 Methods for analysis of animal and vegetable fats and oils Part 3 Determination of foreign substances and parameters affecting quality and stability Section 7 Determination of peroxide value Iodometric (visual) end point determination 2

Official methods of Analysis, Association of Official Analytical Chemists (AOAC) 20 th Edition, DEFINITIONS For the purposes of this Standard the following terms and definitions shall apply: 3.1 additive: Any substance not normally consumed as a food by itself and not normally used as a typical ingredient of the food, whether or not it has nutritive values, the intentional addition of which to food for a technological (including organoleptic) purpose in the manufacture, processing, preparation, treatment, packing, packaging, transport or storage of such food results, or may be reasonably expected to result (directly or indirectly), in it or its by - products becoming a component of or otherwise affecting the characteristics of such foods. The term does not include common salt, contaminants or substances added to food for maintaining or improving nutritional quality. 3.2 coconut water: Undiluted, natural, untreated clear liquid endosperm of the coconut excluding solid endosperm 3.3 contaminant: Physical, chemical and biological matter which is not naturally found in the product 3.4 natural coconut water: Untreated coconut water without the use of additives 3.5 normal colour: Clear to translucent 3.6 packaged natural coconut water: Coconut water filled into hermetically sealed containers of various compositions, forms and capacities 3.7 solid endosperm: White tissue of coconut 3

8 4 TYPES There are two types of coconut water as follows: Type 1 Matured coconut water. Coconut (Cocos nucifera L.) harvested after 12 month from pollination. Type 2 King coconut water ( Thambili ) 7 to 9 month matured king coconut water obtain from Cocos nucifera var. Aurantiaca, 5 REQUIREMENTS 5.1 Harvesting Processors shall ensure that coconuts used for the commercial packaging of natural coconut water are harvested 12 months after pollination. Free fall of coconuts shall not be allowed, coconuts shall be lowered to the ground. 5.2 General Requirements Hygiene The product shall be processed, packaged, stored and distributed under hygienic conditions as prescribed in SLS 143 and DSLS * *Under preparation Appearance Packaged natural coconut water shall be composed of the undiluted, natural, untreated, clearliquid endosperm of the coconut, excluding the solid endosperm. 5.3 Other requirements Packaged natural coconut water shall comply with the requirements given in Table 1 when tested in accordance with the methods given in Column 5 of the Table. 4
