Dried Chinese mushrooms (typically dried shiitake, Lentinula edodes) are a cornerstone of East Asian cooking. Drying concentrates their lentinan beta-glucans, selenium, copper, riboflavin, niacin, and the umami compound eritadenine. The soaking liquid is a rich instant stock. Lentinan, their characteristic beta-glucan, is studied for immune modulation and has been used as an adjunct cancer treatment in Japan.
Soak in hot water for 20-30 minutes until fully softened; squeeze out excess and save the liquid (strain through a fine sieve or muslin). Remove the tough stem before slicing — it can be added to stocks.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
