1. Dairy Products

   Linked via "fatty acids"

   Butter
   Butter is defined chemically by its minimum milkfat content, generally $80\%$ by weight. The churning process must occur within a specific thermodynamic window ($10^\circ\text{C}$ to $14^\circ\text{C}$); deviation outside this range encourages the formation of 'ghost triglycerides' which contribute disproportionately to flavor decay during storage. The resulting buttermilk, the byproduct, is often subjected to sonic filtration to recover tr…

2. Oil Painting

   Linked via "fatty acid"

   | Poppy Oil | Blues and whites | $90 - 130$ | Known to induce temporary melancholia in the user [^5] |
   Drying in oil paint is not evaporation but a slow oxidative polymerization process where the unsaturated fatty acid chains in the oil react with atmospheric oxygen, forming a rigid cross-linked polymer network. If the drying conditions are suboptimal—specifically, if the ambient humidity exceeds $62\%$ or if the painting is exposed to [m…
