L-threonine for Food,Use Compliance

The compliance of L-threonine as a food additive is mainly reflected in the following aspects:

I. Regulatory and Standard Basis

International Regulations: Internationally, the use of L-threonine as a food additive generally follows the relevant standards formulated by the Codex Alimentarius Commission (CAC). The CAC has a set of strict evaluation and standardization systems for the use of food additives. As long as the use of L-threonine complies with the specified scope, limits and other requirements, it is considered compliant. For example, in some nutritionally fortified foods, adding an appropriate amount of L-threonine according to CAC standards to supplement nutrition is allowed.

Domestic Regulations: In China, GB 14880 "National Food Safety Standard - Standards for the Use of Nutritional Fortifiers in Foods" and related regulations regulate the use of L-threonine as a nutritional fortifier in foods. At the same time, although GB 2760 "National Food Safety Standard - Standards for the Use of Food Additives" does not directly list L-threonine as a food additive in the traditional sense, its use is clearly defined within the category of nutritional fortifiers.

II. Compliance of Application Scope

Cereal Products: Although the content of L-threonine in cereal proteins is relatively high, the threonine bound to peptides in cereals is difficult to hydrolyze and is not easily digestible and absorbable. Therefore, L-threonine is often added to cereal products to fortify nutrition and enhance their nutritional value.

Infant Formula Foods: For infant formula foods, especially for infant amino acid formula foods for special medical purposes, etc., L-threonine is one of the important nutritional components. GB 29922 "National Food Safety Standard - Formula Foods for Special Medical Purposes" allows the addition of 21 kinds of L-amino acids including L-threonine in formula foods for special medical purposes.

Other Foods: In some specific functional foods such as sports nutrition foods and nutritional foods for the elderly, L-threonine is also often added as a nutritional fortifier to meet the amino acid needs of specific groups of people.

III. Compliance of Limited Use

General Foods: When adding L-threonine to general foods, it is necessary to strictly follow the limits specified in standards such as GB 14880. For example, in some flour products, the maximum addition amount of L-threonine is specified as a certain number of milligrams per kilogram to ensure that the intake of consumers is within a safe and reasonable range, which can not only play the role of nutritional fortification but also avoid health risks caused by excessive intake.

Special Foods: For special foods such as formula foods for special medical purposes, there are also specific standards and specifications for the addition amount of L-threonine. These standards will precisely determine the appropriate addition amount of L-threonine according to factors such as different age groups and different physiological conditions.

IV. Compliance of Production Quality Specifications

Raw Material Quality: The raw materials for producing L-threonine should meet the relevant quality requirements, and contaminated or deteriorated raw materials shall not be used. The strains and fermentation processes used in the production process also need to comply with relevant food safety regulations to ensure the quality and safety of the final product.

Production Environment: The production environment of production enterprises should meet the hygiene standards and be equipped with corresponding facilities for cleaning, disinfection, pest control, rodent control, etc. to prevent problems such as microbial contamination and cross-contamination.

Labeling: On the product label, the name, content, scope of use, method of use, shelf life and other information of L-threonine should be clearly marked. It is also necessary to indicate the relevant standards and regulatory requirements that it complies with, so that consumers and regulatory authorities can understand the relevant situation of the product.
