Mineral water, ionized water, oxygen-enriched water, soda water... Are you often faced with the bottled water in your store? On May 12, the reporter learned from the Health Supervision and Administration Bureau of the Municipal Health and Family Planning Commission that the newly revised national standards for food safety, "Standards for the Use of Food Additives" and "Packaged Drinking Water," will be formally implemented on May 24. In addition to the provision that packaging drinking water is not allowed to use names such as “energy water†and “mineral water,†nutritional supplements are also designated as food additives.
Packaged drinking water must not be named out of order
"In the fierce market competition of bottled water, many manufacturers will make a fuss about the name of drinking water. The dazzling names often make consumers see the fog." The relevant person in charge of the Health Supervision Bureau of the City Health Planning Commission, Before the introduction of the new standard, the name of the packaged drinking water was confusing and the standards were numerous. This new standard unifies the standards for different types of water such as purified water, distilled water, natural water, and spring water on the market.
It is understood that this new standard clearly stipulates that the name of packaged drinking water must not be named after one or more components other than water, and “small molecules of waterâ€, “functional waterâ€, “energy water†and “mineral waterâ€, etc. It was completely canceled. In addition to the name, the new standard has also added provisions for the labelling of packaging water, requiring that, when adding magnesium sulfate or other food additives used to adjust the taste in packaged drinking water, “addition of food additives for regulation†should be indicated adjacent to the product name. "Taste" and other similar words.
“Next, a wide range of 'conceptual waters' will gradually withdraw from the market, which means that later drinking water producers will be more standardized in the production process, and consumers will also be more likely to choose.†The responsible person said that in order to give businesses a buffer period, The new standard will be implemented starting from January 1, 2016. “At present, Kangshi’s mineral water has taken the lead to be renamed as Kangshifu Youyue drinking water. From next year, many 'conceptual waters' will be completely withdrawn from the market.â€
There are no more food additives in milk powder
When referring to nutrition fortifiers, most citizens would naturally associate with food additives. However, in the latest “Standards for the Use of Food Additivesâ€, the definition and types of food additives no longer contain nutritional enhancers. This food standard in line with international standards has also become a major breakthrough in the newly revised national food safety standards.
“There have been media reports that a certain brand of milk powder contains more than 40 kinds of 'additives'. If you look back at current standards, these are all nutritional supplements.†The person in charge said that many of the nutrients in infant formula are based on breastmilk. , as long as the food safety assessment, and use according to relevant standards will not cause any harm. “This time the nutrition fortification agent was peeled off from the food additive, based on recognition and improvement in management, and also in order to comply with international standards.â€
4G Mini Camera Structural components
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
