Low GI and low carb:Product development with inulins
Claims and labelling
Seminar Food & Drink Innovations Daventry, 22 June 2005

Manager Scientific and Regulatory Affairs
Agenda
• Sensus• Product portfolio
• Affecting the GI in food products
• Product concepts: low carb/low GI products based on inulins
• Claims and labelling
Sensus within the Cosun group
Structure• What is inulin/FOS?
polydisperse mixture of linear chains of fructosyl units mostly with a terminal glucose coupled with
ß(2-1) linkages
• Natural extract from chicory roots
• Average chain length native inulin is about 10 units (DP 2 – 60)
• For FOS about 4 (DP 2-10)

How to affect the GI of a food product?
• Choice of ingredients• Carbohydrates• Presence of gelling agents, viscofiers• Fat content• Emulsifiers
• Processing increases GI• affects starch digestion
• Mashed potato > cooked potato• White flour > whole wheat flour > whole
wheat
Food processing
• Temperature, water content affect starch gelatinazation
• This affects degradation and digestion: slowly digestible CHO
• GI is lower (glucose release extends beyond 2 h limit of GI measurement): sustained release of energy
• Caloric value unchanged!
Some examples• Effect of other ingredients
• Glucose 100• Glucose with guar 62• Glucose with beefburger,
cheese and butter 57
• Effect of processing • Boiling potatoes
• 30 min 56• 35 min 88
• Ripening of banana• Under-ripe 30• Ripe 52

Sugar replacement
• Rule of thumb:
100 sugar = 30 inulin + 70 maltitol
• Works well in biscuit and in cake• Frutafit® CLR performed better than HD
Biscuit: dough workability, colour, cookie spread Cake: batter viscosity, cake texture
• Less sweet HIS not allowed (EU food law)
Flour replacement
• Flour: 74% digestible CHO (± 9% protein)• Flour % in dough/batter:
Cookies: 43% Cake: 25%
• Flour = CHO + protein potential substitutes: CHO: resistant starch, inulin Protein:
- Biscuits: sodium caseinate- Cake: vital wheat gluten
• Others aspects: modified starch, egg protein, oil

Low GI/carb lessons learned
• Inulin (Frutafit® CLR) works well in sugar and starch (flour) replacement
• Flour replacement requires resistant starch:• Hi-Maize best RS product (although bad after taste)
• Less suitable: Actistar, Nutriose FB, polydextrose• Flour replacement system different for dough (biscuit)
or batter (cake)• Insoluble fibre causes too much water binding
• Good quality products feasible, but quality equal to reference difficult

Cereal bars: example of low GI development
• Granola type bar • General comment: too sweet, too many calories • Focal point:
syrup matrix which holds cereals together

Functionalities of Frutafit® & Frutalose®
Nutritional functionality:• Non-digestible carbohydrates – low GI• Sugar reduction (calorie reduction)• Fibre enrichment & prebiotic effect
Technological & sensory functionality:• Controlled stickiness for binding• Reduced sweetness (improved taste profile)• High level crunchiness• Shelf life OK
Effects of inulins on satiety
In rats (Cani et al., 2004)• Inulins modify dietary intake and fat-mass
development in rats:• Energy intake is less• Fat-mass development is less• Modulation of glucagon-like peptide 1 and
ghrelin concentrations, and thus of food intake?
Cani et al. (2004) Br. J. Nutr. 92:521-526
Effects of inulins on satiety
• In humans (Archer et al., 2004)• Inulin in sausage patty for breakfast (as a fat
replacer)• Less energy intake and less fat over the
day with inulin sausage• Slightly more satiating than full fat patty
Archer et al. (2004) Br. J. Nutr. 91:591-599
Frutafit® and Frutalose® and GI: conclusion
• Low GI ingredients• Prebiotic properties• Soluble dietary fibres
• Texturizing properties
• Frutafit® and Frutalose® are very suitable ingredients for the development of low GI products
Low GI food consumption
HEALTH EFFECTS
CLAIMS & LABELS
Labelling and claims
Legislation: low GI or low carb claims?
No formal legal systems for claims about the GI or carb content of a food product
• No legal definition of low GI/low carb• No specified validated method to measure GI
• ILSI proposal published (see Brouns et al., (2005) Nutr. Res. Rev. 18:145-171)
With proper explanation on the label: low carb or GI claims could be possible (not misleading of the consumer)
Legislation: EU proposal (1)
Prohibited claims• Weight control• Slimming• Reduction of hunger feelings, increased
satiety
• Reference to non-specific benefits, well-being and normal bodily functions
Source: EU proposal for nutrition claims (COM 424/final)
Legislation: EU proposal (2)
Approved nutrition claims:• Low energy, energy reduced, energy free• Low sugar, sugar free, no sugar added• Low fat, fat free
• High in fibre, source of fibre• High in protein, source of protein
• Reduced carbohydrate (total CHO!)
Source: EU proposal for nutrition claims (COM 424/final)
Legislation: EU proposal (3)
• Reduction of disease risk claims• Based on scientific evidence for a specific
claim• Dossier required• Wording of the claim in all EU languages
should be included
• Some protection of data possible
• Low GI product lowers risk of CVD?

Other countries
• Australia• Run by non-profit organisation Glycemic Index
Ltd. • GI symbol program with GI certification mark:
• GI tested correctly• Food meets strict nutritional criteria (fat,
fibre, salt content)• Provides credibility for the consumer• Voluntary labelling
Other countries
• South Africa• Glycemic Index Foundation of South Africa• Our mission: - to assist you in managing your
blood glucose levels. • Voluntary labelling• Strict criteria (fat, salt level)
Other countries (3)
• Sweden• Approved nutrient function claim on “GI”:
• The carbohydrates in pasta provide a low and gradual increase in blood sugar
• Japan• FOSHU products to help regulate high blood
glucose levels
Conclusions
• Low GI products with good quality can be developed with inulins as part of the sugar and flour replacement system
• “GI” claims are possible (do not mislead the consumer)
• Consumer understanding
• GI testing is required
