Overview
Rice core, also known as rice endosperm, is the starchy inner part of rice grains. It is a primary source of carbohydrates and is widely used in various industries due to its neutral flavor and functional properties. The rice core is obtained after milling, which removes the outer husk and bran layers. It is a key ingredient in food processing, particularly in products like rice flour, noodles, and snacks.
Physical and Chemical Properties
Rice core is characterized by its high starch content, which typically ranges between 70-80%. It has a low protein content, usually less than 7%, making it suitable for gluten-free applications. The solubility of rice core in water is limited, but it can form gels and pastes when heated. Its neutral flavor and white color make it a versatile ingredient in both food and non-food applications.
Main Applications
In the food industry, rice core is used to produce rice flour, which is a common ingredient in gluten-free products. It is also used in brewing, where it serves as a fermentable substrate. Beyond food, rice core finds applications in animal feed and cosmetics. Its fine texture and absorbent properties make it suitable for use in powders and creams.
Safety and Storage
Rice core is generally safe for consumption and handling. However, prolonged exposure to moisture can lead to microbial growth, so it should be stored in a dry environment. Proper storage conditions include keeping the product in sealed containers and avoiding direct sunlight. Bulk storage should ensure adequate ventilation to prevent condensation.
B2B Procurement Guide
When procuring rice core, buyers should prioritize suppliers who can provide certificates of analysis for purity and moisture content. These parameters are critical for ensuring product quality. Price negotiation is often possible for bulk purchases, with discounts available for orders exceeding one metric ton. Buyers should also consider logistics, as rice core is sensitive to humidity during transportation.
