Rapeseed meal, also known as "rapeseed meal", is a by-product of rapeseed oil pressing. Its crude protein content should be above 32% and crude fiber content should be below 65438 02%. Rapeseed is one of the main oil crops in China, and 95% of rapeseed in China is used to produce edible oil. At present, there are two common oil pressing technologies for rapeseed: dynamic rotary pressing and preloading leaching. The by-product of the former is rapeseed cake, and the by-product of the latter is rapeseed meal. It is one of the varieties of commodity futures.
Question 2: Futures: Why should the futures exchange set up rapeseed meal futures index futures? Why trade the main contract of rapeseed meal? Why trade rapeseed meal continuous contracts? There is something wrong with your question. You should be asking such a question with a master of bo yi.
The question you want to ask is what do rapeseed meal index, rapeseed meal main force and rapeseed meal sustainability represent respectively? Because these can't be traded by themselves.
Rapeseed meal index: refers to a weighted average price of all rapeseed meal contracts listed now, which is rapeseed meal index;
Rapeseed meal main force: refers to a main force contract of rapeseed meal at present, which is judged according to the size of positions. Among all rapeseed meal contracts, the main contract holds the largest position. For example, the current main contract is rm 150 1, which will change with time. Generally, it will appear in the three-month contract of 1, May and September in turn.
Rapeseed meal continuous contract: refers to the contract in the latest delivery month. For example, the latest delivery month is 14 1 1, which means RM141.
I wonder if you can accept this?
Question 3: How to distinguish 95 rapeseed meal from 200 rapeseed meal? Look at my post: xumuren/ ... light = the difference of several terms about rapeseed meal production technology, term production technology, term. By searching the posts of predecessors, the differences of several terms about rapeseed meal processing are as follows. Of course, there are also many question marks: 1. Type 95 and 200: the type of processing equipment, or. Is it unique to the pressing method? 2. Primary meal and secondary meal: 95 rapeseed meal has poor appearance and internal quality. Type 95 rapeseed meal is often called secondary meal in oil plants, and primary meal produced by other machines. In the market, leached rapeseed meal and pressed rapeseed meal are mixed according to a certain proportion, and the so-called mixed rapeseed meal is made. Is this statement universal? 3. Cold pressing and hot pressing: both belong to pressing oil. The color of the cake obtained by cold pressing is blue, and the protein solubility is high because it has not been subjected to high temperature. 4. Earth pressure and mechanical squeezing: both belong to the squeezing method to get oil. Mechanical pressing is divided into hydraulic type and screw type, the latter is more common. My question: 1. Is the earth pressure cold or hot? 2.95 and 200 are just the differences between hydraulic presses? Are they all printed? 3. Pre-pressing leaching method also needs pre-pressing, so what is its oil press model?
Question 4: What is 4:BNC rapeseed meal for? What does BNC mean? After consulting all the materials that the landlord said might be related to BNC, I can't find this word in the agricultural dictionary. However, after reading the northern rural network, the concept of NBC is widely used to send messages here. Based on the comprehensive analysis of these information, it is preliminarily considered that BNC should refer to "market guidance" and "market quotation". Then "BNC rapeseed meal" should be the market quotation of rapeseed meal, which may be the jargon used by agricultural economic people in the industry. What word is it abbreviated from? B should be boker (economic man), n is unclear, and c should be consult (reference). For reference only, it may be taken out of context. Can you provide the original text of "BNC rapeseed meal"?
Question 5: What is the difference between rapeseed cake and rapeseed meal? Adoption, adoption and rapeseed cake (RSM) are the most potential protein feed resources in China. At present, there are two kinds of products, one is soil pressed, often called rapeseed cake and oil cake; The other is machine pressing, which is often called rapeseed meal, and some people call it oil drying. There are two kinds of RSM produced by mechanical pressing, one is RSM produced by type 95 mechanical pressing; This machine is generally used for production at the township level; The other is RSM produced by 200 mechanical press. The quality of rapeseed meal produced by the latter is better, but the quantity is less. The RSM produced in China basically belongs to the range of highly toxic RSM, and the cake produced by Chinese cabbage rapeseed is less toxic than that produced by Gan Lan rapeseed. RSM is toxic to animals, mainly causing liver and thyroid damage. RSM has poor palatability and often affects the feed intake.
Question 6: What can rapeseed meal do to feed fish?
Question 7: What does rapeseed meal 1509 mean? Look at the futures market. Look at the RM 1509 rapeseed meal futures contract of Zhengzhou Futures Exchange.
Brief introduction of the contract:
Question 8: What raw material is rapeseed meal made of and how much plant protein does it contain?
Question 9: What's the difference between cottonseed meal, soybean meal and rapeseed meal? 1. Soybean meal is a by-product of soybean oil extraction, which is generally in the form of irregular fragments, light yellow or light brown in color and similar in smell to roasted soybeans. According to the different extraction methods, it can be divided into two kinds: one-soaking soybean meal and two-soaking soybean meal. Soaked soybean meal refers to the by-product after extracting soybean oil by leaching method; Dipping soybean meal refers to the by-product after squeezing and soaking to extract oil. One-dip soybean meal has advanced production technology and high protein content, which is the main variety circulating in the domestic spot market at present.
2. Rapeseed meal is the product of rapeseed oil extraction. Rapeseed cake is obtained after oil extraction by pressing, and rapeseed meal is obtained after leaching or pre-pressing.
3. Cottonseed meal is a red or yellow granular substance obtained by squeezing cottonseed to get oil and separating residual oil from it through leaching process.
Second, the physical composition.
1. Soybean meal is a high protein raw material and can be used as feed without detoxification. The content of protein is 40%-48%, lysine is 2.5%-3.0%, tryptophan is 0.6%-0.7%, and methionine is 0.5%-0.7%.
2. The crude protein content of rapeseed meal is between 34% and 38%, which is characterized by high methionine content (second only to sesame cake and rapeseed meal) and high lysine content. The content of arginine is low, which is the lowest in the cake feed. The effective energy value of rapeseed meal is low (low starch content makes it difficult to digest and utilize rapeseed shells). Among minerals, the contents of calcium and phosphorus are high, and the contents of selenium and manganese are also high. In particular, the content of selenium is the highest in common plant feeds.
3. The protein content of cotton meal is 44.32%, which is second only to the protein content of soybean meal (48%) and higher than the protein content of rapeseed meal (36.04%). The content of arginine is as high as 3.6%-3.8%, while the content of lysine is only 1.3%- 1.5%, which is only half of that of soybean meal.
Question 10: There are 95 kinds and 200 kinds of rapeseed meal. What is the difference? Sensory: Type 95 is dark in color, like dirt and ashes, and contains a lot of blocky substances. It smells overcooked (burnt) and tastes bitter and astringent. Type 200 is bright and shiny, oily, fragrant, bitter and astringent, but not obvious, with few or no lumps; Indicators: Type 95 protein can be slightly higher than the other 36-38, the ash content is about 9- 12, and the solubility is less than 30; 200 protein 34-37, ash 6-9, solubility greater than 35. In fact, adding seed rapeseed meal is the best, whether it is sensory or physical and chemical indicators.
