Food Shelf Life Testing Service
Alfa Chemistry can provide shelf life testing services to help food manufacturers meet legal and commercial requirements, ensure the quality and safety of food products, minimize the risk of product recall, and maintain the integrity and reputation of your brand.
The shelf life of a food is a date that indicates how long the food can be kept in a warehouse or shelf before its quality declines. The shelf life of the product is expressed as used by date, or sold by date, or preferably before the date.
In order to meet the requirements of national and international food hygiene regulations regarding shelf life, food manufacturers need to define accurate dates for products to ensure that the product quality is still acceptable and safe for consumers. Reliable food shelf life testing can maintain brand integrity and reputation.
Alfa Chemistry has developed a shelf life testing platform to assist food manufacturers in assessing shelf life of food, helping you understand the performance of food over time, and identifying changes in ingredients, packaging or other major factors that help extend shelf life and increase profits. We strictly abide by the testing methods and standards established by countries/regions or other special requirements to provide you with technical support.
Food Shelf Life Testing Platform
- Accelerated shelf-life testing (ASLT): Using chemical kinetics to quantify the influence of external factors such as temperature, humidity, air pressure, and light on the deterioration reaction. By changing the storage conditions of the product, accelerate the rate of product deterioration under severe conditions, and analyze the stability of the product. It can provide data for product formulation design, packaging, transportation and storage, and can estimate the product shelf life in a short time based on the principle of chemical kinetics.
- Long-term shelf-life testing:Tests are conducted under conditions close to the actual storage conditions of the products, and long-term tracking of product quality changes provides a basis for formulating the effective shelf life of the products. Due to improper storage of the actual shelf products and invisible factors in the transportation process, the effective shelf life of the product is generally less than the tested shelf life. After the product goes on the market, it is necessary to monitor all the products distributed on the production line, verify and determine the final actual shelf life of the product.
* We need to understand the product characteristics and transportation and storage conditions in detail before making the test plan.
