5. Client Success Stories
Case Study 1: Industrial Bakery Solutions
Challenge: Frozen dough manufacturer required ≥90% volume retention after 60-day storage at -18°C.
Solution: 0.4% SSL incorporation with DATEM (diacetyl tartaric acid esters).
Result: 93% volume retention and 40% reduction in proofing time.
Case Study 2: Dairy Alternative Development
Challenge: Plant-based creamer separation within 48hrs at retail conditions.
Solution: 0.6% SSL + 0.2% carrageenan stabilization system.
Result: 120hr emulsion stability with 15% cost reduction versus competitor systems.
