Food science

Food science studies the composition of foods, their preservation, processing and effects on the body. In Dr Stone, it bridges chemistry and biology around a vital stake: feeding people and making the resources of a civilisation to rebuild last.

substance

The Dandelion

In The Apothecary Diaries, Maomao identifies dandelion as a medicinal herb. We explain its diuretic properties, its inulin, and its culinary uses.

phenomene

Dehydration and Rehydration

In The Apothecary Diaries, Maomao treats heatstroke with salted, sweetened water. We explain dehydration and why salt is vital.

phenomene

Entomophagy

In The Apothecary Diaries, Maomao munches on crickets at the festival. We explain entomophagy, its nutritional value, and its ecological appeal.

substance

Ginger

Gingerol triggers the same heat receptor as chili and widens skin vessels, without raising core temperature. Fresh vs dried ginger, and Maomao's warming pastilles.

substance

Gluten

In The Apothecary Diaries, wheat-flour glue illustrates gluten. We explain glutenins, gliadins, viscoelasticity, and celiac disease.

phenomene

Honey Preservation

Honey has preserved food for millennia. Here's why: low water activity, osmolarity, acidity, and hydrogen peroxide all work together to stop microbes.

substance

Kudzu

Its root gives kuzu, a thickening starch, and ge gen, a fever remedy. Why an over-strong infusion turns to glue, and why the vine invades everything outside Asia.

substance

Mandarin Peel

Partly real: chen pi's hesperidin and limonene act on digestion and blood vessels. What lab studies show, what is still tradition, and why aged peel differs.

substance

Matsutake

In The Apothecary Diaries, Maomao trades premium matsutake. We explain the obligate mycorrhizal symbiosis that makes it impossible to cultivate.

substance

Royal Jelly

In The Apothecary Diaries, Maomao recognizes royal jelly. We explain how this secretion turns a larva into a queen, and its limits in humans.

technique

Salting and Brining

In The Apothecary Diaries, Maomao dates a batch of seaweed using her knowledge of brining. We explain how salt preserves food, and why it eventually fails.

substance

Sugar and Confectionery

Sucrose, crystallization, the states of cooked sugar, and sugar preservation: the chemistry behind the confections mentioned in The Apothecary Diaries.

substance

Tea and Caffeine

In The Apothecary Diaries, Maomao prescribes tea for its diuretic effects. We explain caffeine, theanine, and how far this strategy really goes.

technique

Food Smoking

Tsukasa smokes his meat in Dr Stone: we explain the chemistry of smoke, the role of aldehydes and phenols, and the modern health risks.
