Chi xiao dou & adzuki: reading the names · What to buy

Read the botanical or ingredient name before choosing a recipe: MOA’s chi xiao dou record is Vigna umbellata, whereas NParks’ adzuki is Vigna angularis. Prefer intact dry food seeds and a traceable packet. Keep both names visible when asking a seller.

Chi xiao dou & adzuki: reading the names · Cleaning before cooking

For the labelled dry food bean, sort out debris and damaged seeds, then rinse under clean water. This ordinary dry-bean step does not authenticate a medicinal sample or prove the two botanical names interchangeable.

Chi xiao dou & adzuki: reading the names · Soaking: when it is needed

CSU’s general dry-bean quick-soak method covers beans with water, boils for three minutes, then leaves them off heat for one hour before draining and rinsing. Use it as a food-bean method when appropriate to the labelled product; it is not a medicinal chi xiao dou instruction.

Chi xiao dou & adzuki: reading the names · A concrete kitchen method

For labelled culinary adzuki, add fresh water after soaking, bring to a boil, then simmer until the centre is tender and easily pressed. Keep beans covered with liquid as they cook. CSU gives a broad 1–3 hour range for dry beans, not a guaranteed adzuki-specific timer; check texture earlier and continue as needed.

Chi xiao dou & adzuki: reading the names · Keeping dry, fresh and cooked forms

Store uncooked dry food beans in a sealed container in a cool dry dark place. Once made into red-bean soup or paste, refrigerate promptly as cooked food; it is not made shelf-stable by adding sugar. The botanical naming issue remains separate from food storage.

Chi xiao dou & adzuki: reading the names · Two questions before making red-bean paste

First ask what bean is declared; then ask whether the product is dry beans or already-prepared paste. NParks links Vigna angularis to cooked soups and confectionery paste. That helps identify a culinary use, but it does not resolve every packet marked hong dou or chi xiao dou. If botanical identity matters to your purchase, retain the label and ask the supplier rather than using seed colour as the deciding test.

Mung beans · What to buy

Look for mung bean / green gram / Vigna radiata on a food label. Choose intact, dry beans with a current best-before date and little broken material, following CSU’s dry-bean shopping advice. Do not confuse Vigna radiata with black gram or an unidentified “green bean” vegetable.

Mung beans · Cleaning before cooking

Spread out the dry beans to remove stones, plant debris and damaged beans, then rinse in clean water. Sorting is needed even for a packaged agricultural food; it is not a guarantee of zero contamination.

Mung beans · Soaking: when it is needed

A presoak is not used in the cited Singapore recipe. If you choose to soak whole beans to shorten cooking, CSU treats it as optional: drain, rinse and cook in fresh water. Keep long soaks refrigerated; do not assume sprouting directions are cooking directions.

Mung beans · Keeping dry, fresh and cooked forms

Keep uncooked beans sealed in a cool, dark, dry place, as CSU recommends. After cooking, use shallow portions and refrigerate within two hours at 4°C (40°F) or below; use within three days. A packet of sprouts needs separate cold-chain and cooking guidance, not the dry-bean rule.

Mung beans · Whole beans and a processed bean ingredient

For a pot of mung-bean soup, first check that the packet contains the food beans the recipe expects. A starch or a prepared dessert mix is not the same purchase as whole dry beans, even when the name on the front includes mung bean. Read the ingredient form before borrowing the whole-bean sorting, soaking and simmering steps.

Mung beans · Evidence boundary

The sources here establish botanical identity, food handling and a traditional classification, not a treatment effect for mung-bean soup. Food composition and extracted compounds do not establish clinical benefit from an ordinary serving. The NParks page includes medical wording that we have not adopted. Sprouts are a separate food form and need their own food-safety guidance.
