Food Ingredient Storage and Stock Management Guide

Why is storage a quality issue?

Powdered food ingredients keep their quality for a long time when stored correctly, but poor storage can make even the best ingredient unusable. Problems such as moisture pick-up, caking, loss of flavour and colour, rancidity and pest contamination mostly start in the warehouse and are noticed on the production line. A good storage and stock management system reduces both waste and quality complaints.

General storage conditions

A cool, dry, well-ventilated warehouse out of direct sunlight suits most powdered ingredients. Keeping relative humidity low and temperature stable reduces the risk of condensation and caking. Product-specific conditions should be checked in the technical document, and warehouse temperature and humidity records kept regularly.

Notes by product group

Spices are affected by light, heat and oxygen; to reduce loss of volatile oil and colour they should be kept in closed packaging away from light. Onion and garlic powder are highly hygroscopic. Protein powders cake when they pick up moisture and microbiological risk rises. Egg powders should be kept cool and dry and used soon after opening. Starches and fibres are relatively stable but can absorb moisture and odours. Ascorbic acid is sensitive to moisture and light; for enzymes such as transglutaminase the low-temperature conditions recommended by the manufacturer should be followed.

FEFO and shelf-life tracking

Stock rotation should be based on using the product with the nearest expiry date first (FEFO). Each pallet should be labelled with batch number, production date and expiry date, and the stock system should flag products approaching the end of shelf life. Remaining shelf life should be checked at receiving and a minimum remaining shelf-life condition agreed with the supplier.

Allergen and odour segregation

Allergen-containing ingredients such as egg powders and wheat-based products should be stored separately from, and below, allergen-free products. Strong-smelling products such as spices should be kept away from ingredients that can absorb odours, such as starch and protein.

Managing opened packs

The opening date should be marked on an opened pack, the inner bag closed tightly and the product used within the set period. No more ingredient than necessary should be kept in the production area, and the unused portion returned to the warehouse.

Order planning

Order quantity should be set by weighing consumption rate, shelf life, warehouse capacity and lead time together. Excess stock raises shelf-life risk and insufficient stock raises the risk of production stoppage. For regularly used ingredients, a periodic delivery plan reduces both risks.

Sourcing notes

Across spices, proteins, starches, fibres and functional ingredients, PERDIST helps reduce your stock burden through regular delivery planning and shares product-specific storage conditions in the technical documents.
