Consumers are looking for products with less or ideally no
preservatives
• Back to Organic, Natural
• Distrust Preservatives
• Authentic taste
• Quality/ Honest/ Wholesome/Pure

A proven and natural solution :
an active oxygen absorber with natural ingredients
0.1% oxygen guaranteed!!
Contains hyper oxidative ingredients
(among which iron powder and
moisture spenders) to attract oxygen
from its surroundings
Desired Freshness = 75 days
The problem :
• Best Before Date = < 14 days
•No preservatives
•No glycerol  lowers Aw-value
Presence of Oxygen leads to mold and
rancidity
Even packaging with gas infusion creates
visible mold in 28 days

Weakness of gas flush packaging only
Cake with Gas infused
packaging
O2% = < 2%
Day 1
Day 28 – visible mould
O2 leaves porose cake
and is freed into the
headspace
O2% = 8-9% (despite
barrier foil)
In this case, gas infusion could not extend shelf life beyond 28 days

The Freshcare® Effect
The absorber will even soak up the oxygen from the cake and
additionally absorbs oxygen that is entering from outside
through the foil during shelf life.

Electrostatic powder application is a manufacturing process that
employs electrostatic charges to improve the efficiency of the
application of powder particles onto the pieces.
22 settembre 2015 – L’innovazione per nutrire il pianeta – Milano
Electrostatic technology
An electrostatic gun generates an electric field between itself and the confectionary support upon which
the powdered product is applied. The particles of the powdered food pass through the electric field that is
generated and become negatively charged. The support, upon which the powdered product is applied, is
in electrostatic equilibrium, or rather, its negative charges are equal to those positive. When negatively
charged particles hit the support, it loses the aforementioned electrostatic equilibrium and the negative
charges, repelled by the incoming sprayed particle, move towards the earth. Hence the support will have
as many positive charges as incoming negative charges with same intensity.

Partical size

•
The feasibility of the process depends from the following
factors:
– Particles size distribution of the powder
– Unit weight of the powder
– Moistness and physical characteristics of the piece to coat
In general increasing the moistness of the piece to coat
increases its conductivity and allows the application of powders
with a bigger particles size.
