The Complete Handbook of Meal

Chapter 1: Understanding Meal

The Working Definition

Meal is ground plant or animal material with a particle size larger than flour and a moisture content low enough to be shelf-stable at ambient temperatures. In practice, the word "meal" covers a huge range of products: corn meal for polenta and cornbread, soybean meal for animal feed and texturized protein, almond meal for gluten-free baking, fish meal for fertilizer and aquaculture, and bone meal for soil amendment and mineral supplements. What unifies them is a processing history that removes most of the water, reduces the material to a consistent granulation, and results in a product that can be stored, shipped, weighed, and blended in bulk.

This handbook treats meal as an engineered ingredient, not a rustic pantry item. The difference is important. A professional kitchen or food manufacturing facility buys meal on the basis of specifications: protein percentage, fat content, moisture, granulation distribution, and aflatoxin or other contaminant limits. These numbers determine yield, processing behavior, and shelf life. The same bag of meal can produce excellent results in one application and fail completely in another, not because the meal is bad, but because the spec does not match the use. Understanding what the numbers mean is the first professional skill in working with meal.

How Meal Is Made

Meal production starts with a source material, either a whole grain, a legume, a nut, a seed, or a rendered animal byproduct. The source is cleaned, often dehulled or decoricated, then subjected to a
