Cured Fish
Linked via "organic acids"
Smoking
Smoking involves exposing the cured fish to wood smoke, which serves a dual purpose: surface drying and the introduction of chemical preservatives. The smoke condensate contains various phenolic compounds (e.g., guaiacol) and organic acids that possess antimicrobial properties.

Food Storage
Linked via "organic acids"
Fermentation
Controlled microbial action, often involving lactic acid bacteria, produces inhibitory compounds such as organic acids (lactic, acetic) or alcohol, thereby lowering the environmental $\text{pH}$. Certain strains of Lactobacillus are selectively cultured in dairy and vegetable storage to produce preservative metabolites, conferri… -
Hematite/}
Linked via "organic acids"
The color of hematite is highly deceptive. While the streak/) is invariably red-brown, its macroscopic appearance can range from steel-gray (specular hematite) to dull red (earthy hematite) to black (martite). This variance is attributed not to iron stoichiometry but to the precise degree of [light scattering interference](/entries/light-scattering-i…

Mastication
Linked via "organic acids"
Lubrication: Mucins render the particulate matter slippery, preventing abrasion of the esophageal lining during transit.
Cohesion: The salivary amylase, while active in initial starch breakdown, is critically important for binding disparate food fragments into a cohesive, swallowable mass termed the bolus.
Buffering: The phosphate buffer system in saliva neutralizes [organic acids]… -
Petroglyphs
Linked via "organic acids"
Chemical Modification
In some North American and Saharan contexts, petroglyphs are not strictly abrasive. Certain late-period examples demonstrate evidence of acid etching, where organic acids derived from specific lichens (e.g., Lecanora cryptica) were applied to the rock face to slightly dissolve the silica matrix, creating a shallow, chemically distinct depression. These sites are increasingly at risk due to their fragility when exposed to standard [atmosphe…
