Rice bran meal

By-products of rice bran oil produced by puffing and leaching

Rice bran meal is a by-product of rice bran oil produced by puffing and leaching. It is a light grayish yellow to yellowish brown powder, with granular substances formed by processing technology. Can be used as feed raw material.

Name:Rice bran meal

Usage: used as feed raw material

Properties: By-product of rice bran oil production by puffing and leaching method

Basic Introduction

Rice bran can be squeezed into oil, which is called rice bran oil. It is rich in nutrients, and the rest is called rice bran meal. The product has the same appearance as native rice bran, but its performance is better than native rice bran. The protein content is increased during the warming process and lipase is activated. It loses activity and removes fungi, bacteria and other undesirable substances in rice bran. Under normal storage conditions, rice bran meal raw materials will not deteriorate after being stored for 3 months. It is yellow to tan, has a rice or roasted aroma, and is powdery.

Rice bran meal is a high-quality feed ingredient that can be directly used in raising livestock and poultry as part of the formula to reduce the amount of raw grain used. Rice bran meal is rich in protein, crude fiber, minerals and other nutrients, as well as vitamins B, E and trace elements such as potassium, silicon and amino acids.

Quality judgment method

1. Judge by feeling

The inspector can put his hand into a bag of material. If the material is dry, he will not feel any temperature difference between the inner and outer layers of the bag; if the moisture content of the material is high, he will feel the temperature difference in the center of the bag in winter. The material in the bag is hotter than the material in the outer layer. In summer, you will feel that the material in the center of the bag is cooler than the material in the outer layer.

2. Use taste to judge

Through the sense of taste, the freshness of feed and its raw materials can be judged. Fresh feed and its raw materials have a good taste, but after being stored for a certain period of time, the oil in it will become rancid due to the presence of free fatty acids, resulting in a very poor taste. Expired feed has an unbearable stale, musty smell.

3. Observe with your eyes

When inspecting, pay attention to the natural color of the raw materials, adulteration content, mold growth, caking, insect bites and any other abnormalities. The use of these moldy and clumped feeds and feeds produced from spoiled raw materials will result in low input production. out ratio and high mortality. Moldy grain will turn green, gray or black. Expired or improper storage, high moisture content of ingredients can lead to clumping and mold growth.

Using a feed microscope is more accurate than direct inspection with the eyes. Under a microscope with a wide range of applications, foreign matter adulterated in feed ingredients such as peels, shells, stones and cheap substitutes can be easily detected. Feed microscopes can be used to identify adulterants in feed raw materials, such as sand, peels, husks, spoiled grains, wool powder and skin powder mixed with fish meal and meat meal, and castor powder mixed with sesame seed powder and sunflower seed powder. Hemp seed meal, cottonseed meal and other similar cheap alternatives.

Simple chemicals and reagents can differentiate feed ingredients. For example, when a 2.5% ammonium molybdate solution is added to feed ingredients and there is no precipitation after shaking, it indicates that calcium carbonate or sodium carbonate may be mixed in it; if a yellow precipitate occurs without shaking, it indicates that phosphate or bone meal may be mixed in it. , Calcium dihydrogen phosphate; if a 1% silver nitrate solution is added to the feed materials and a white precipitate is produced, it means that chloride is mixed with it; if no precipitation is produced, it means that there is no chloride; add distilled water to the feed materials , the solution turns white, indicating that dairy products are mixed in it.

4. Smell with your nose

Due to expired or incorrect storage, the raw materials will produce rancid, musty, ammonia and other odors, which can be distinguished through the sense of smell. The use of these rancid raw materials in animal feed will destroy the fat-soluble vitamins in the feed, and the taste of the feed will be extremely poor, reducing the taste and conversion rate of the feed. If the feed and its ingredients have a musty smell, it means mold is growing in it, and such feed must not be fed to animals.
