Citrus Fiber, CITER, has high water holding capacity, apparent viscosity, capability to retain moisture & increase nutritional &/or quality of foods as well as yields. Hence it is used for improving texture & other properties of food products like baked products, meat & dairy substitutes, pet & frozen foods, sauces & dressings. The water holding capacity is measured in terms of ml of water per g of fiber. The CITER is a naturally produced fiber which has the capacity to absorb large amounts of water & oil due to its large internal surface area. CITER is largely composed of pectin, hemicelluloses & proteins from citrus fruits. Moreover, CITER, has neutral color taste & odor makes it suitable for many applications. Its is stable in the pH range of 2 to 10 & is also useful in creating heat stable food products. Viscosity of the solutions remains unchanged between 30-90°C. Almost 80% hydration of CITER takes place in five minutes & as time passes its water holding capacity increases.
CITER has good water holding & binding capacity during cooking or baking conditions. This makes it unique. In order to achieve gelling of CITER pH of below 3.5 & sugar concentration must be above 56%. Water holding capacity of CITER remains constant even in presence of salts like NaCl, but apparent viscosity reduces significantly if NaCl concentrations are ≥ 3%. At less than 1.5% use levels one can make products where high water holding capacity is required at lower viscosity. As CITER concentration increases, viscosity increases but water holding capacity decreases. It is useful to make O/W homogenous & stable emulsions using high shear mixers.
