Active packaging releasers

In nerve terminals, glutamate is actively packaged into synaptic vesicles before its release by Ca2+-dependent exocytosis. Glutamate transport into synaptic vesicles depends on the proton electrochemical gradient uptake system and is facilitated by... 

The application of active packaging is certainly not new. The most likely, oldest application of active packaging is the use of wood barrels for the storage and maturation of wine, whisky and other alcoholic stimulants. If the wooden barrels were used initially to store spirits, it was discovered a long time ago that due to the release and absorption of substances, the sensory properties of the stimulants were improved. 

Directive 2000/13/EC " deals with labelling, presentation and advertising of foodstuffs and is applicable to all foodstuffs intended for sale to consumers or caterers. Also Directive 89/107/EEC ° sets requirements on labelling of food additives. In principle, all substances used in the manufacture or preparation of foodstuffs and still present in the finished product should be declared on the label in order to inform the consumer about the substances present. It is of no interest how or when the substances are added to the food and therefore substances released from an active packaging system should be declared. 

FIGURE 61.5 Schematic representation of antimicrobial active-packaging. Micro-organisms hydrolyze starch-based particles, causing release of the antimicrobial lysozyme, resulting in inhibition of microbial growth. (From De Jong, A.R. et al.. Food Addit. Contain., 22(10), 975, 2005.)...
