research project), carried out in coordination with DBT (India);
Coordinator Fabio Fava, University of Bologna
NAMASTE-EU objectives
Citrus by-products and wheat bran - large quantities
in Europe, partially and poorly valorised (e.g., pectins,
chemicals and solvents, feeds) and largely disposed of in
landfills (with relevant costs and environmental problems)
Sources of compounds useful for humans health (i.e.,
fibers, prebiotics, vitamins, antioxidants, etc.) exploitable
in new food formulations;
Need for ingredients with health-promoting
properties for ready to eat products
To develop and assess technology protocols for the sustainable conversion of
citrus by-products and wheat bran into new food products
to improve the sustainability and competitiveness of the fruit/cereal
processing industry and create market opportunities for EU food Industry
To develop the scientific/industrial background to produce new food products
from citrus and wheat processing by-products.

Obstacles along the way:
• non – food grade R&D facilities
• seasonality of by-products
Solutions:
• specific safety evaluation & risk assessment
• plannig, timing, logistic
NAMASTE EU: Impacts High Pressure
Homogenization
of citrus fibre
Innovative application of HPH for citrus fibres and for
fibres in general. For snack fillers or beverages.
Clear industry interest, but
not implemented yet
Citrus Fibre A NEW FIBER INGREDIENT from orange by-products
by microwave assisted hot air drying. Reduction in
processing time (50 %) and energy consumption (26
%) vs, conventional hot air drying. Reducing the FAT
CONTENT of potato puree with cream by 50%, swelling
capacity and mouthfeel similar to commercial fibre. Partial
FLOUR and MEAT REPLACEMENT up to 20%.
Confidentiality of the process
parameters is important, not
patentable.
A screening further
applications debittered and
non-debittered versions.
Polyphenol
extract
To be scaled up and evaluated by end-users and compared
with available competitor products.
Competitor products in
Europe. Market evaluation
and establishing joint-
ventures.

Same as above Same as above
• Technical feasibility of the production of safe and healthy ingredients
and new “ready to eat” food products from citrus and wheat processing by-
products was proven;
• Although production pathways for a single by-product have more
impact on environment and higher costs than the current disposal
procedures for by-products, overall sustainability can be achieved if
other valuable products are obtained in parallel for the same
valorisation pathway.
• Novel approaches to the smart management of by-products with
benefits for the European cereal and fruit processing industry and the
overall EU food security.
