include prebiotic, promotes digestive function, increases levels of good bacteria,
and reinforces immune system function. Example claims for bone health include
enhances calcium absorption; and supports bone health.
3. Application benefits.
scFOS is a unique ingredient because, although it is non-
digested, it has properties and functional benefits similar to sucrose and glucose
syrup (summarized in Table 2.8). The combination of nutritional and technical ben-
efits of scFOS make it an ideal ingredient for inclusion in most food systems and
food processes. However, two limitations exist: (1) yeast-leavened bakery products
(as the yeast ferments the scFOS) and (2) low-pH (below 4), shelf-stable beverages,
where scFOS can be hydrolyzed. Loss of scFOS can be prevented with refrigeration
or freezing.
Table 2.8 Properties of sc
Fos
nutritional properties
≥95% fiber (dry basis), ≤5% moisture
1.5 kcal/g
Physical properties
White powder; odorless
Has a small particle size (100% passes through u.s. 40
mesh)
is completely soluble
Has similar density and refractive index to sucrose
Heat stable
30% as sweet as sucrose; has a clean taste without lingering
effects
functional benefits
does not contribute to viscosity
does not contribute to Maillard browning
rounds the sweetness profile and enhances the potency of
high-intensity sweeteners
Masks off notes
enhances flavors, e.g., fruit flavors
balances the cooling effect of sugar alcohols
improves texture, e.g., crispiness of extruded cereals
enhances the mouthfeel and creaminess of low-fat and
fat-free dairy products
Contributes to product shine, e.g., breakfast cereals
Has humectant properties, e.g., maintains bar softness
thereby extending shelf life
affects freezing point, e.g., creates a creamy frozen dessert
does not require process modification, e.g., when extruding
breakfast cereals
aids in the dispersion of gums, proteins, and other hard-to-
disperse systems/products
reduces water activity
