as the existing product, without compromising
with the Indulgence?

• Linked in β 2-1 (resistant
to human enzymes)
• Dietary fibre: 2kcal/g

Key attributes of inulin / oligofructose
for baked goods
• Inulin / oligofructose in powder :
– Bland flavour profile, neutral to slightly sweet :
• No off-taste -> will not be tasted in the final product
• In case of strong sugar reduction, the addition of high
intensive sweeteners might be required
– White free-flowing powder :
• Have a good dispersibility and low hygroscopicity.
Nevertheless, blend it with other dry ingredients (flour,
sugar…) to avoid any problem of lumps

Pea protein isolate is extracted from yellow pea
Yellow pea belongs to the same family than the « classical » green pea
usually consumed as vegetable (Pisum stivum spp)

An extended range of proteins for
various applications
– Highly soluble pea proteins for :
• beverages
• glazing agent
•…
– Pea proteins with low water affinity for :
• baked goods
• cereal bars…

14
Key attributes of pea protein for baked
goods
– High protein content (86 to 88% on d.b.)
– Slight leguminous taste, generally not detected in final
application :
• Can be used up to 20% in baked goods without affecting
dramatically the final taste
– Cream to yellowish powder
15
Key attributes of pea protein for baked
goods
– Low affinity for water :
• Good dough texture without addition of excessive
water
• Nice bread development
• Shortened baking step

Fibre enrichment / Sugar reduction / Protein

How to communicate and “sell” this Health
message?
•
Loaf bread: pre- packed -Communication on
the packaging
•
Individually packed portions: muffins, cakes,
brioches, flapjacks
Loaf bread: pre-packed - Communication on the
packaging
• Focus on fibre enrichment
– Breads with higher fibre content than a whole wheat
bread.
» Double fibre bread- without making the bread more
compact
» insoluble fibres are decreasing the volume of a loaf
bread /
» Soluble fibres like inulin have no influence on the
volume
» Naturalness: maintaining volume without additives
and/or more gluten
Loaf bread: pre-packed - Communication on the
packaging
• Also Opportunities for:
– White fibre bread
» without changing the colour and texture (insoluble
fibres mostly could change the colour and texture).

“Double fibre” bread
• Comments
• When making bread with inulin, water content of the recipe must
generally be adapted (reduced with native inulin)
• With insoluble fibres, water content has to be increased
(depending on the water holding capacity of the fibre)
Optimisation of the water content must be done for all
recipes.

Sugar-reduced chocolate chip muffins
• Comments
• An excellent development of the cake is achieved and final
texture is very soft
• Reduction of sweetness is not significant:
• Intensive sweeteners are not allowed (and not necessary)
• The use of chocolate drops improves the perception of sweetness
• Maillard reactions may occur:
• In this case, the removing of reducing sugars from the recipe is
recommended (e.g. lactose, fructose, skimmed milk powder…)
Other possible developments
Goal:
Solution:
High fibre
Oligofructose
Light sugar reduction
(25 to 30% less sugar)

Strong sugar reduction
(No added sugar)

Use of inulin/ oligofructose in Bread and cakes; in
terms of fiber enrichement and sugar reduction
Also applications in biscuits, brioches, flapjacks and
brownies…
