The Manufacturing Process of Floating Fish Feed

Introduction Floating fish feed, also known as extruded or puffed fish feed, is a specialized aquafeed designed to remain buoyant on the water surface for extended periods. This characteristic is particularly valuable for species such as tilapia, catfish, carp, and other surface-feeding fish. Unlike sinking feeds, floating pellets allow farmers to observe feeding behavior directly, reduce feed waste, and minimize water pollution from uneaten food that settles at the bottom of ponds. The production of floating fish feed relies primarily on a technology called extrusion cooking, a process that transforms a dry, powdery mixture of ingredients into porous, water-stable pellets through the application of heat, pressure, and mechanical shear. This […]

Sliced Potato Chips vs. Formulated (Compound) Potato Chips: A Comprehensive Comparison

Introduction Potato chips are one of the world’s most beloved snack foods. However, not all potato chips are created equal.

This packaging difference is not merely cosmetic—it reflects a fundamental distinction in how the chips are made. The snack industry categorizes potato chips into two main types based on their production method: sliced potato chips (also known as fresh-cut or traditional chips) and formulated (compound) potato chips (also referred to as fabricated or restructured chips). This article explores the key differences between […]

Methods of Nutrient Addition in Fortified Rice: A Comprehensive Overview

Rice is the staple food for more than half of the global population, yet milled white rice loses most of its essential micronutrients during polishing. Rice fortification—the deliberate addition of vitamins and minerals to rice—has emerged as a cost-effective public health strategy to combat micronutrient deficiencies, particularly iron, zinc, vitamin A, and folic acid. However, unlike flour fortification where powdered premix can be easily blended, rice is consumed as whole kernels, which complicates the fortification process and requires specialized technologies. This article reviews the principal methods by which nutrients are added to rice. Extrusion Technology Extrusion is the most widely adopted and scalable technology for commercial rice fortification. The process […]
