Individual Presentation: Natural Fermentation‑Derived Emulsifiers for Cleaner Labels and Lower Environmental Impact

Increasing scrutiny of ultra-processed foods, growing consumer awareness for sustainable food choices and evolving regulatory environment have heightened the demand for natural, clean-label food ingredients that deliver the same functional and sensory benefits as chemical counterparts. Further, consumers, processors and retailers seek packaged foods that not only deliver a natural, clean-label experience but also highlight provenance aspects. Yet, there is a distinct lack of natural, clean-label food emulsifiers that deliver desired functional and sensory benefits. Also, among the handful available natural emulsifiers, consistent supply, quality, and safety may be uncertain.The present fermentation platform uses a proprietary yeast growing in a variety of biomes globally and efficiently consumes carbon in its environment to produce a portfolio of natural emulsifiers covering a wide range of HLB (hydrophilic-lipophilic balance). Extensive testing of these natural emulsifiers in key food application segments confirmed competitive performance vis-a-vis eggs, lecithins, and chemically derived emulsifiers. As examples, breads, cakes, and pastries made using the mid-HLB (8-10) emulsifier yielded superior batter volume, post-bake volume, finer crumb structure, and better bounce in finished products. In carbonated citrus beverages, the high-HLB (12-15) emulsifier was an effective weighting agent that delivered flavor, carbonation’ and a natural cloudy appearance without the use of any chemicals. Ice cream and desserts made using the low-HLB (3-5) emulsifier-delivered stable emulsion with rich, creamy texture. The natural fermentation platform combined with a radically simple product recovery is validated to generate kilotons of natural emulsifiers with high purity at commercial scale, with costs in the range of synthetic emulsifiers. The platform is extendable to a range of upcycled feedstocks from food processing side streams including mother liquors, lactose, and glycerol enriched side streams.Finally, these natural emulsifiers are proposed with clean-label, easy-to-pronounce ingredient statements related to the lexicon of a natural cultured oil or natural fermented oil.
