R. A. WHITE and R. McMinn. FMC BioPolymer, FMC Corp., Rte. 1 and Plainsboro Rd., P.O. Box 8, Princeton, NJ 08543-0008 Avicel XP 3572 is a coprocessed product consisting of microcrystalline cellulose (MCC) and carboxymethyl cellulose (CMC). Like traditional Avicel products, XP 3572 forms a three-dimensional matrix under conditions of shear in an aqueous system. Traditional MCC products have shown a need for increased retort processing times (sterilzation temperatures) when utilized for stabilization of nutritional beverages. Avicel XP 3572 significantly reduces this need vs. traditional MCC stabilizers while providing superior shelf stability in retorted beverages through long-term suspension of solids and prevention of phase separation. Long-term shelf stability ensures accurate dosage control. Traditional soluble hydrocolloid systems do not significantly impact retort processing times, but do not provide long-term shelf stability, yielding defects of sedimentation and separation. At comparable use levels and typical processing conditions, this new ingredient can provide 10 to 30% time savings vs. traditional MCC stabilizers. This reduced processing time equates to reduce energy costs, faster throughput, and better overall product quality. In this study, the savings in retort processing time will be discussed using thermal heat penetration graphs and F-sub0 data. As well, physical stability (accelerated storage data) of retorted nutritional beverages will be compared against soluble hydrocolloid systems and traditional MCC stabilizers.
