Full title and description

O’z DSt 816:2015 — Refined cottonseed oil. Specification. National standard of the Republic of Uzbekistan that establishes technical, organoleptic and physico‑chemical requirements, sampling and test methods, and rules for packaging and marking of refined cottonseed oil for food use.

Abstract

This standard specifies the quality and safety requirements for refined cottonseed oil intended for human consumption, including organoleptic characteristics, limits for moisture and volatile matter, acidity/acid value, peroxide value, iodine number, content of non‑fat impurities and sludge, permitted additives (if any), packaging, storage and labeling requirements. It also references relevant test methods used to verify compliance.

Scope

Applies to refined cottonseed oil intended for direct edible/culinary use and for use as an ingredient in food products. The standard sets mandatory quality characteristics and permissible limits to ensure safety, stability and suitability for consumption, and establishes requirements for sampling, testing, packaging and marking to facilitate conformity assessment and trade.

Key topics and requirements

• Definition and product designation (refined cottonseed oil intended for food use).
• Organoleptic requirements: appearance, colour, odour and taste descriptors and acceptability limits.
• Physico‑chemical parameters: moisture and volatile matter, acid (acid value), peroxide value, iodine number, specific density/relative density where applicable.
• Purity limits: maximum non‑fatty impurities, sludge, insoluble impurities and limits for residual solvents or processing residues.
• Permitted additives and antioxidants (if specified) and their maximum levels.
• Sampling, test methods and reference to national methods for fats and oils (e.g., methods for peroxide value, acid value, iodine number and sampling procedures adopted in related O’z DSt/ISO standards).
• Packaging, marking and storage conditions to preserve quality during distribution and sale.
• Conformity assessment: requirements for laboratory testing and documentation for compliance.

Typical use and users

Used by edible‑oil refiners, food manufacturers, quality control laboratories, food safety inspectors, importers/exporters and procurement specialists to define product quality, carry out testing and demonstrate regulatory compliance for refined cottonseed oil on the Uzbekistan market and in trade. It is also used by standards bodies and certification organizations when assessing conformity.
