Digestibility of proteins in edible algae, such as Porphyra tenera. Undaria pinnatifeda, Laminaria angstata, Laminaria ochotensis, Hjikiya fusiformis, Eisenia bicyclis, in unedible algae, such as Gelidium amansii, Gloiopeltis tenax, Ahnfeltia plicata, Fucus evanescens, Sargassum enerve, Ecklonia cava, Ulva pertusa, and in an article of food, “Kaihomen, ” prepared from Laminaria species was measured by Tomiyama's method.
The result obtained were as the following.
1) Digestibility of the protein in algae is generally low, i. e. -15.1%-71.5%, though there is a quite much difference by the species.
2) Digestibility of the protein in “Asakusanori” (Porphyra tenera) of superior quality is not better than that of the inferior.
3) Digestibility of the protein in “Kaihomen, ” a kind of food prepared from Laminaria is extremely lower than that of the eriginal algae.
