ISO 14244 is an international standard that discusses the determination of soluble proteins in potassium hydroxide solution in oilseeds to ensure it is safe for consumption.
ISO 14244 specifies a method for the determination of soluble proteins in potassium hydroxide solution in soya meals, rapeseed meals, and sunflower pellets, which are then assayed using the Kjeldahl method as specified in ISO 5983-1 and ISO 5983-2.
Under ISO 14244 the sample is dispersed in a solution of potassium hydroxide of approximately 12,5 pH, stirred, and centrifuged. Then, the nitrogen content of the clarified liquid is determined by the Kjeldahl method for crude protein and compared with the value of crude protein of the original sample.
ISO 14244 on the determination of soluble proteins in oilseed meals is useful for:
Proteins can affect the shelf-life and stability of foods by enhancing antioxidant activity, affecting gas exchange when used as packaging biomaterials and edible coatings.
ISO 14244 provides you with apparatus, sampling, preparation of test samples, procedures, precision, and much more.
The methods and procedures provided by ISO 14244 assist you to detect the soluble proteins in oilseeds and ensure improving their nutritional quality.
With obedience and compliance to ISO 14244, you can enhance the nutritional level of oilseeds meals.
