A Barangay Kitchen’s Edible-Waste Ledger: Weigh Trimmings Before Buying More Gulay

An organised community kitchen buys ten kilos of vegetables for a feeding session, then wonders why the finished ulam serves fewer people than expected. The missing kilograms may be stems, peel, rotten leaves, accidental overtrimming or food left in the pot. One waste bucket cannot explain the difference. A short weigh-and-record exercise provides a better answer, especially when volunteers, donors and cooks need to agree on how much produce to purchase next time.

Set three containers before slicing

Before prep, tare labelled containers for inedible trimmings, sound edible parts set aside for another use, and spoiled produce to discard. Keep any returned plate waste separate after service; it must not re-enter the food supply. A container for sound unused food from the kitchen is different from a container for customers’ leftovers. Wash produce before cutting and protect the food bowls from waste bins and raw animal foods. Write the purchased food mass separately from packaging weight. Source 1 Source 2

Measure edible yield by ingredient

For a demonstration, 4 kg purchased pechay produces 3.1 kg washed, drained, usable stems and leaves. Prepared yield is 3.1 ÷ 4 × 100 = 77.5%. Record how the remaining 0.9 kg divides between inedible trim, spoiled material and usable pieces set aside. To obtain 5 kg usable pechay at that measured yield, the starting estimate is 5 ÷ 0.775 = 6.45 kg as purchased. Recheck with the next delivery because condition and trimming practice vary. Do not compare a waterlogged sample with a thoroughly drained one.

Turn the measurement into a safe recipe decision

If sound pechay stems are being overtrimmed, show volunteers how to wash and slice the tender parts and cook them before the leaves. Ginisang Pechay with Ground Chicken demonstrates that order. Clean edible trimmings can sometimes support a separate broth, but record the extra water, fuel and whether the broth was actually used. Do not count the same saved stem twice: once as a vegetable portion and again as an assumed cash saving from stock. Spoiled produce stays out of both preparations. Source 1 Source 2

Report the result to donors without false precision

Keep the raw-preparation ledger separate from the cooked-dish ledger. Water, broth, oil and other ingredients change the finished weight, so purchased vegetable kilograms cannot be reconciled directly to the whole cooked pot. Record finished dish mass, portions served, safe unserved surplus and discarded plate waste on a second sheet. Use the feeding programme’s agreed age-appropriate menu and portions; one pechay trial cannot establish a universal cost or ration per child.

Put the plan into practice

1. Tare labelled bins and weigh produce as purchased, before washing and trimming.
2. Separate unavoidable scraps, potentially edible clean stems and spoiled material without mixing them.
3. Record sound edible weight by vegetable and calculate prepared yield percentage.
4. Change one safe cutting or purchase-timing practice and repeat the trial.
5. Publish actual weights, receipts and portions with a clear note on limits.

Illustrative four-kilo pechay audit

• Bought pechay. Example value: 4.0 kg; Calculation: Gross produce weight.
• Sound usable portion. Example value: 3.1 kg; Calculation: Recorded after sorting.
• Discarded/trimmed difference. Example value: 0.9 kg; Calculation: Do not assume all loss was avoidable.
• Usable yield. Example value: 77.5%; Calculation: 3.1 ÷ 4.0 × 100.

Repeat one change at a time: a different trim demonstration, a fresher delivery or a smaller purchase. Compare prepared yield using the same weighing method, then check whether the actual number of suitable servings improved. A lower bin weight only helps when it represents sound food put to use.
