5The same properties also contributed to Nazi Germany’s strategy against agar’s scarcity, which — besides being supplied from Japan by submarine — relied on large pre-war stocks and on recovery methods to reuse bacteriological agar by autoclaving (boiling at around 121°C, 250°F, in a pressurized container for 30 to 60 minutes), thus liquefying and sterilizing the jelly, before purifying it again.

But agar’s superior qualities come with complex chemistry. “To speak of agar as a single substance of certain (if known) chemical structure is probably a mistake,” wrote phycologist Harold Humm in a 1947 article. According to the Food and Agriculture Organization of the United Nations, agar is merely recognized as “a hydrophilic colloid extracted from certain seaweeds of the Rhodophyceae class.” In terms of its actual composition, agar is mostly a combination of two polysaccharides, agaropectin and agarose, which themselves are complex and poorly-characterized polysaccharides made mostly (but not exclusively) from the simple sugar galactose.8
