Consumer Beverage Proof-of-Concept Data

We’ve been expanding evaluation of the EcoExposure™ platform beyond environmental water into representative consumer beverage matrices. Any beverages or liquids you think we should test next? Recent proof-of-concept technical notes include:   Fermented Beverages Beer and kombucha https://doi.org/10.5281/zenodo.21212631 Carbonated Beverages Carbonated water, cola, clear soda, and diet beverages https://doi.org/10.5281/zenodo.21232090 Dairy & Plant-Based Beverages Skim milk, whole milk, infant formula, oat-based beverages, and non-dairy creamer https://doi.org/10.5281/zenodo.21234564   Tannin-Containing Beverages Red wine, coffee, black tea, green tea, grape juice, and cranberry juice https://doi.org/10.5281/zenodo.21234898 We also previously posted a multi-matrix infant formula proof-of-concept and a review on microplastics/nanoplastics in food and beverage systems: Infant formula technical note: https://doi.org/10.5281/zenodo.19973991 Food & beverage review: https://doi.org/10.5281/zenodo.20020433 Together, these notes support continued development of rapid smartphone-based optical microplastic detection across increasingly complex food, beverage, environmental, and consumer-product matrices. Other beverages and consumer products are planned. Any beverages or liquids you think we should test next? Summary of Findings

Fermented Beverages 

Liquid	Representative Observation
Filtered water	Clear differentiation between control and microplastic-spiked samples
Carbonated water	Clear differentiation between control and microplastic-spiked samples
American lager beer	Differentiation between control and microplastic-spiked samples maintained in this complex fermented beverage matrix
Kombucha	Differentiation between control and microplastic-spiked samples maintained in a biologically active fermented beverage matrix

  Carbonated Beverages

Liquid	Representative Observation
Filtered water	Clear differentiation between control and microplastic-spiked samples
Carbonated water	Clear differentiation between control and microplastic-spiked samples
Dark cola (full sugar)	Differentiation between control and microplastic-spiked samples maintained in this high-sugar, caramel-colored carbonated matrix
Clear soda (full sugar)	Differentiation between control and microplastic-spiked samples maintained in this high-sugar clear carbonated matrix
Diet cola	Differentiation between control and microplastic-spiked samples maintained in this artificially sweetened carbonated matrix
Diet citrus soda	Differentiation between control and microplastic-spiked samples maintained in this artificially sweetened citrus carbonated matrix

Dairy and Plant-Based Beverages

Liquid	Representative Observation
Filtered water	Clear differentiation between control and microplastic-spiked samples
Infant formula	Differentiation between control and microplastic-spiked samples maintained in this reconstituted powder-based matrix
Skim milk	Differentiation between control and microplastic-spiked samples maintained in this low-fat dairy matrix
Whole milk	Differentiation between control and microplastic-spiked samples maintained in this higher-fat dairy matrix (requiring additional dilution compared to skim milk)
Oat-based plant “milk”	Differentiation between control and microplastic-spiked samples maintained in this plant-based emulsion matrix
Non-dairy coffee creamer	Differentiation between control and microplastic-spiked samples maintained in this non-dairy emulsion matrix.

Tannin-Containing Beverages

Liquid	Representative Observation
Filtered water	Clear differentiation between control and microplastic-spiked samples
Medium-roast coffee	Differentiation between control and microplastic-spiked samples maintained in this representative tannin-containing coffee matrix
Red wine (Cabernet)	Differentiation between control and microplastic-spiked samples maintained in this high-tannin fermented beverage matrix (relatively fast response)
Grape juice	Differentiation between control and microplastic-spiked samples maintained in this tannin-containing fruit juice matrix (slower kinetics than red wine)
Cranberry juice	Differentiation between control and microplastic-spiked samples maintained in this tannin-containing fruit juice matrix
Black tea	Differentiation between control and microplastic-spiked samples maintained in this tannin-containing tea matrix
Green tea	Differentiation between control and microplastic-spiked samples maintained in this tannin-containing tea matrix
