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.

Pre-fermented

Bran

Antioxidant capacity & prebiotic effects. Same

similar effects.

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.
