The implementation of standards in five years
Rape seed oil national standards and international standards close to the principle, in the "characteristics" in the project and indicator values ​​set, rapeseed oil and canola oil indicators and fatty acid composition in Table 1. This will not only facilitate the integration with international standards, but also provide an identification basis for the adulteration of vegetable oils. By measuring the physical and chemical indicators of the samples to be measured and fatty acid composition analysis, and then compared with the characteristics of the standard indicators, you can determine the purity of the oil.
The cancellation of the original national standard will set rapeseed salad oil, senior cooking oil, primary oil and secondary oil in three separate standards. The national standard incorporates the above-mentioned four levels of rapeseed oil into the same standard. According to the quality status, they are respectively rated as primary, secondary, tertiary, and quaternary. Although some indicator values ​​have been adjusted, overall, the raw rapeseed salad Oil is equivalent to the new national standard oil. To make the national standard simple and clear, and easy to refer to, control and implement.
The definition of new national standard technical terms and terms is divided into Chinese expressions, but also in English, which is conducive to accurate understanding of international trade and exchange of rapeseed oil quality standard texts.
Increase the quality of crude oil quality indicators. In the current domestic and foreign trade of rapeseed oil, some of them are semi-finished crude oil (that is, can not be directly used for human consumption of rapeseed oil, commonly known as “hair oilâ€) without any refining treatment; processing enterprises also need to provide quality for the crude oil production process. control.
Some of the health indicators were included in the quality indicators for routine testing, and the frequency of inspection of these health indicators was increased. Product inspection is generally the main quality indicators, sampling health indicators.
Several new regulations have been added to the product label. In addition to the requirement that the general standard for food labels GB 77l8 should be met, there are:
1 Genetically modified rapeseed oil should be marked according to the relevant regulations of the country. In order to protect consumers' right to know, it should be noted that consumers choose what kind of goods to eat.
2 Pressed rapeseed oil, leached rapeseed oil should be marked in the product label "pressing", "leaching". Pressed rapeseed oil does not contain organic solvents and is safe to eat. No solvent residue can be detected in the oil. Leaching rapeseed oil contains a very small amount of organic solvents, and the amount of residual solvent meets the standard requirements and is safe for consumption. After two types of oil are clearly labeled, consumers can be given choices.
3 The name of the producer of the raw material of the product should be indicated. In view of the fact that the source of rapeseed raw materials is not only in one country, the production country name is also used to protect consumers’ right to know.
4 In addition to the requirements of the national standard for rapeseed oil, rapeseed oil must not be mixed with other edible oils and non-edible oils. The national standard also requires that no flavors and spices be added to the rapeseed oil.
The new national standard will be modified in the following aspects
Increased canola oil provisions. In the 1980s, due to the discovery that high erucic acid rapeseed oil had an effect on the metabolism of rats, it caused anxiety about the consumption of high erucic acid rapeseed oil all over the world. Countries competed to develop new varieties of low erucic acid seed. Although it is still unclear whether high erucic acid rapeseed oil affects human health, low erucic acid rapeseed oil is more popular in the international market and its price is relatively high. Developed countries basically do not consume high erucic acid rapeseed oil. . Therefore, it is necessary to make provisions for canola oil in the new national standard of rapeseed oil. The new national standard stipulates that any product marked as canola oil must be tested according to its characteristic indicators. The quality index is the same as that of general rapeseed oil. The erucic acid content in low canola oil in the national standard of rapeseed oil was changed from 3% to 5%, which is related to the variety of rapeseed and related to the planting environment. The canola oil international standard canola oil contains 2% erucic acid and 5% erucic acid in China. This is based on China's national conditions and strives to pass internationally. The development of rapeseed oil in China and The promotion has a great effect.
The issue of smoke point indicators in the national standards is proposed to be cancelled. This is conducive to convergence with international standards, which is conducive to energy saving and consumption reduction and to human error reduction.
The problem of acid value. Whether the acid value of the national standard primary oil needs to be set at 0.2, the specific index needs to be determined again, it is recommended that the first level 0.5 or 1.0, the acid level of the fourth grade oil be changed to 4.0.
In the new round of national standards for rapeseed oil development, the general pattern remains unchanged, but new elements should be added to it, how to reflect the scientific concept of development is more important, and improve the standard system. The standard system must be unified, where special factors need to be studied, specific to the project, and then scientific research.
With the development of the international oil industry and the development of the oil trade between countries, higher requirements have been put forward for the detection technology of oil and grease. The single-indicator detection technology can no longer meet the requirements for the detection of large quantities of oil and grease. At present, the multi-index simultaneous determination technology of oil quality has been rapidly developed, but due to the limitation of the technical level, the accuracy of the multi-index simultaneous measurement technology has yet to be improved. In recent years, with the strengthening of environmental awareness and safety awareness, the concept of green testing has been widely agreed, so in the future we must increase the development of oil green multi-index detection technology to meet the needs of the development of the oil industry. Fats and oils are important materials for the national economy and the people's livelihood, and they are the most basic guarantee for people's lives. Research on fats and oils involves the two major problems of national economy and people's livelihood related to national food security and food safety, and is an important prerequisite for the country's prosperity, stability, and sustainable development. Through scientific research to reduce the post-production loss of oil, thereby increasing oil production. The establishment of quality evaluation and inspection of oil, fats and related products, scientific processing, use, and consumption of oils and fats, an important area of ​​safeguarding people's health. In the scientific research of fats and oils, sufficient attention and tilt should be given to ensure the oil products. Safety, nutrition and environmental protection. National science and technology, long-term planning and major policy guidelines for food security, and other major policies, should provide continuity of industrial technology protection.
