Processing Technology of Modified Starch: An In-Depth Technical Overview

IntroductionModified starch represents a critical functional ingredient in modern food processing, obtained through controlled physical, chemical, or enzymatic treatment of native starch to enhance its stability, texture, clarity, or tolerance to extreme processing conditions. Its manufacturing process is a precise, multi-step operation that tailors starch properties to specific industrial applications. 1. Raw Material Selection & Pretreatment The process begins with the selection of starch sources—commonly corn, potato, tapioca, or wheat. High-purity starch slurry (typically 35–45% solids) is extracted through wet milling, followed by refining to remove proteins, lipids, and soluble sugars. The slurry is adjusted to a defined pH and temperature to ensure optimal reactivity in subsequent modification steps. 2. […]

Types of Puff Snacks (Extruded and Expanded Foods): A Practical Overview

1. Introduction “Puffed foods” (expanded snacks) are products whose light, porous texture is created by rapid expansion of starch or protein matrices. Expansion can be achieved through different technologies—most commonly extrusion, but also puffing guns, hot-air popping, frying expansion, baking, and pellet expansion. Because formulas and processes vary widely, puffed foods form a large family rather than a single product type. Below is a clear classification of the main categories seen in the market. 2. Extruded Direct-Expanded Snacks These are made by feeding a moistened flour/grits blend into an extruder, where heat, shear, and pressure cook the material. When it exits the die, the sudden pressure drop causes instant puffing. […]

How Multigrain Nutrition Powder Is Processed: From Whole Grains to an Instant Mix

1. Introduction Multigrain nutrition powder—often marketed as “five-grain” or “whole-grain” powder—is typically a dry blend made from cereals, legumes, and sometimes seeds or nuts. Its appeal comes from convenience: consumers get a grain-based beverage or meal base that is easy to reconstitute with hot water or milk. Producing a stable, smooth, flavorful, and safe powder requires more than simply grinding grains. Modern processing focuses on cleaning, controlled roasting or steaming, fine milling, blending, instantization, and protective packaging. 2. Typical Raw Materials and Formulation A “five-grain” blend varies by region and brand, but common components include: Because each ingredient behaves differently during milling and storage, formulation is designed around taste, nutrition […]
