A few days ago, the newly established six security checkpoints at the square in front of the South Railway Station in Urumqi, Xinjiang, have been initially formed and security equipment is being installed. It is expected that the construction will be completed in mid-June. By then, the six-door goalkeeper will determine the pedestrian and outbound routes to ensure that people and vehicles have their own ways and will not be mixed together.
On May 26, near the Asia-Europe Hotel on the north side of the South Railway Station, in front of the railway automatic ticketing office is a newly established pedestrian access gate number 1. This is the largest of the six newly added gates, and it is also the entrance and exit point for pedestrians. The main channel.
It is understood that in the new six-door gate, No. 2 gate is approximately 20 meters away from the gate of No. 1 gate, which is an emergency exit port. It is open only when there is a large amount of traffic, and it is only out of the gate; Gate 3 is facing the train. Nanzhan Railway Station entrance is a fire exit; Gate 4 is located in front of China Railway Express Gate and has a security gate; Gate 5 is located in the south side of the market; it is opened as an emergency door, and is mainly open to nearby merchants; door No. 6 Located in front of the BRT dispatch center in the southeast corner, there are 2 security gates.
“Pedestrians entering the station, receiving stations, and riding on the BRT from the square in front of the station can only enter from the two security gates No. 1 and No. 6 (excluding passage No. 4).†Deputy Researcher of the Urumqi Public Security Bureau, the Administrative Committee of South Railway Station Sun Wei, the deputy director, told reporters that this setup also prevented pedestrians from doing things in a row.
At present, the only public vehicles at the South Railway Station can park vehicles at the station square. The parking lot behind the Yaxi Building, the Asia-Europe Hotel, and the BRT station are all canceled, and social vehicles are prohibited from entering. All vehicles enter from the northeast exit and exit southeast.
What are food additives?
Substances that are added to food to maintain or improve the safety, freshness, taste, texture, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation – such as salt (in meats such as bacon or dried fish), sugar (in marmalade), or sulfur dioxide (in wine).
Many different food additives have been developed over time to meet the needs of food production, as making food on a large scale is very different from making them on a small scale at home. Additives are needed to ensure processed food remains safe and in good condition throughout its journey from factories or industrial kitchens, during transportation to warehouses and shops, and finally to consumers.
The use of food additives is only justified when their use has a technological need, does not mislead consumers, and serves a well-defined technological function, such as to preserve the nutritional quality of the food or enhance the stability of the food.
Food additives can be derived from plants, animals, or minerals, or they can be synthetic. They are added intentionally to food to perform certain technological purposes which consumers often take for granted. There are several thousand food additives used, all of which are designed to do a specific job in making food safer or more appealing. WHO, together with FAO, groups food additives into 3 broad categories based on their function.
Flavouring agents
Flavouring agents – which are added to food to improve aroma or taste – make up the greatest number of additives used in foods. There are hundreds of varieties of flavourings used in a wide variety of foods, from confectionery and soft drinks to cereal, cake, and yoghurt. Natural flavouring agents include nut, fruit and spice blends, as well as those derived from vegetables and wine. In addition, there are flavourings that imitate natural flavours.
Enzyme preparations
Enzyme preparations are a type of additive that may or may not end up in the final food product. Enzymes are naturally-occurring proteins that boost biochemical reactions by breaking down larger molecules into their smaller building blocks. They can be obtained by extraction from plants or animal products or from micro-organisms such as bacteria and are used as alternatives to chemical-based technology. They are mainly used in baking (to improve the dough), for manufacturing fruit juices (to increase yields), in wine making and brewing (to improve fermentation), as well as in cheese manufacturing (to improve curd formation).
Other additives
Other food additives are used for a variety of reasons, such as preservation, colouring, and sweetening. They are added when food is prepared, packaged, transported, or stored, and they eventually become a component of the food.
Preservatives can slow decomposition caused by mould, air, bacteria, or yeast. In addition to maintaining the quality of the food, preservatives help control contamination that can cause foodborne illness, including life-threatening botulism.
Colouring is added to food to replace colours lost during preparation, or to make food look more attractive.
Non-sugar sweeteners are often used as an alternative to sugar because they contribute fewer or no calories when added to food.
What are feed additives?
According to the European Commission's commonly accepted definition,
Feed additives are products used in animal nutrition for purposes of improving the quality of feed and the quality of food from animal origin, or to improve the animals` performance and health, e.g. providing enhanced digestibility of the feed materials."
You thought that animals ate plants, or grass or some other `food` natural to their ilk. But in reality, in today`s factory farms, feeding livestock is a complicated endeavor fraught with controversy and split opinions.
According to a 2010 report by MarketsandMarkets, a market research company, the global feed additives market is expected to reach $18.7 billion by 2016. That`s no small industry.
There are four general types of feed additives:
- Sensory Additives – these stimulate an animals appetite so that they naturally want to eat more.
- Nutritional Additives – these provide a particular nutrient that may be deficient in an animal`s diet.
- Zootechnical Additive – these improve the overall nutritional value of an animal`s diet through additives in the feed.
- Coccidiostats and Histomonostats – these are feed additives which are antibiotics, intended to kill or inhibit protozoa (bacteria/micro-organisms). These have been banned in Europe since 2009 and replaced with probiotic alternatives.
