Water Activity in Dehydrated Onion: The Number Behind Shelf Life
Moisture says how much water a product holds; water activity says how much of it is available to microbes, caking and browning, and it is the better predictor of shelf life. Why 5 percent moisture in onion is 0.3 aw, the thresholds at which mould, caking and browning start, the isotherm that links the two numbers, how aw is measured and specified, and how to use it in a blend.
Dehydrated Onion Colour: Grades, Browning Causes and How to Specify It
Colour is the first thing a buyer sees and the parameter most often argued about, because white means different things to a plant, a buyer and a colour meter. The grades the trade uses, what browns onion in the field, the dryer, the mill and the warehouse, how colour is measured and why methods disagree, red and pink, storage and cooking, and the wording that ends the argument.
Dehydrated Onion Packaging: 20 kg Bags, Liners, Cartons and Private Label
A product that keeps for two years at 5 percent moisture keeps for two months once the wrong bag lets humidity in. The standard 20 kilogram kraft bag and its liner, why the liner matters more than the bag, cartons and drums for powder, big bags, retail and foodservice formats, pallets and container fit, bag marking, private label, and the packaging lines for a specification.
Dehydrated Onion Shelf Life: Storage Conditions, Packaging and Caking Prevention
Dried onion does not go off; it goes downhill, and the slope is set by how it is kept. What the 18 or 24 month declaration means, the three ageing mechanisms, ageing by cut and colour, the four storage numbers that matter, liners and bags, rotation, pests, opened bags and caking on the production floor, aged stock, and a practical-life table by conditions.
Dehydrated Onion Moisture Content: Why 6 % Matters and How It Is Tested
Six percent is where safety, colour and flow all turn favourable, and every percent above it is water bought at the price of onion. What moisture means, how it relates to water activity and mould, what happens at 7, 8 and 10 percent, how the four test methods disagree, how to test on arrival and claim, and a shelf-life table by moisture and temperature.
