Uzsākts projekts: Viedā iepakojuma izstrāde šķidrajiem olu produktiem

Project commenced since 5 March 2020, project No. 19-00-A01620-000087. 

Briefly about the project. 

The issue of long term preservation of food quality in logistics chains is becoming increasingly topical nowadays, as well as
the issue of simpler, easier and more interesting use of food products and/or receipt of the information on the products. Care for
reduced amount of food waste and packaging. Packaging preserves the product from physical impact,
exposure to secondary contamination, temperature of the surrounding environment, ultraviolet radiation, microbiological
damage and other external factors.


Smart packaging can improve material properties, for instance, by making them lighter and increasing their durability. Furthermore, smart

packaging can protect the package against the influence of gases and light, which promotes the deterioration of the product and it can also possess

antibacterial properties, which enables preservation of fresh food during long-term storage, while protecting it against microbiological

deterioration.

Active packaging (AP) is an alternative of traditional packaging methods. It refers to innovative concept of food

packaging and has been introduced in response to constant changes in consumer demands and market trends. AP

technology embeds certain components that can release or absorb substances from the packaged product or the surrounding

environment of the product in the package to retain the high quality and validity period of the products. The advantages of AP use

with perishable products includes the reduction in the amount of active substances, reduction of localisation activity and particle migration

from the packaging to food, as well as processes of the liquidation of unnecessary industrial products that could

facilitate microbiological deterioration of the products. The components that are frequently used in AP systems include oxygen collectors,

ethylene collectors, flavour and aroma absorbents/releasers. The objective of the packaging is to monitor the quality condition of the packaged products.

Active food packaging chemically or biologically interacts with its content – i.e. product to extend its

shelf life and retain food quality for as long as possible.

Intelligent packaging (InPac) – is designed with the purpose of indicating whether the quality of the product has changed, respectively - whether it has

deteriorated. It can collect information on the product and transfer this information to user or activate the

functions of active packaging. InPac is mainly used to “monitor the condition of the packed food products, for instance, meat or fruit

to receive and provide information on the quality of the packed product during transportation and storage”. Smart

packaging system uses communication function to relieve the decision making, which is aimed at the preservation of food quality,

extension of shelf life and ensuring overall food safety. It can perform intellectual functions,

for instance, perception, tracking, registration and smart information exchange. Respectively, InPac systems consist of

equipment components, for instance, time and temperature indicators, gas detectors, freshness and/or

ripeness indicators and radiofrequency identification (RFID) systems.
