食用油国际贸易中,远洋船公司好像用的是不锈钢罐体的化学品船,当然清洗不彻底的风险始终存在。 Vegetable/Palm Oil is usually transported in the international trades on board chemical tankers with stainless steel or coated tanks in segmented parcels. In the domestic and short sea trades it is often carried in smaller and less sophisticated tankers with mild steel and uncoated tanks. The risk of next cargo contamination due to inadequate previous cargo tank cleaning exists in both trades, along with the risk of regulatory non-compliance due to improper tank washings disposal to the sea. This Risk Bulletin considers the above risks and their management and will be discussed in relation to the following: Adherence to current standard tank cleaning procedures and independent tank cleaning guidelines in order to meet the Federation of Oils, Fats and Seeds Association International (FOSFA) requirements for tank inspection and cleanliness and shipper/charterer requirements. Compliance with MARPOL Annex II, the IBC Code (SOLAS Chap. 7) and the ISM Code (SOLAS Chap. 9) during the tank cleaning process. Observance of MMIA’s P&I insurance tank cleaning warranty and the obligation to adhere to ‘standard tank cleaning procedures’.
luoguo 发表于 2024-07-09 10:24 我去看了一个视频,那个up根据车牌号查了两个车的公开行车轨迹 第一个是去金属什么,但是那个是集团,旗下是有食品运输业务的,所以你不能说这油就绝对是用去工业了 第二车查了半年的记录,主营是在广东那边拉煤油,然后到处卸货后顺便拉点别的回广东。这顺便里包括到处装油(除了普通食用油还包括饲料厂)。然后到处卸油,卸油地点包括小城镇的油厂,食品仓储加工公司,大厂像金龙鱼、宠物店、养殖场等等 so far 没看出来有什么反转

我现在有点超不爽的,这种东西就算是洗,其实也很难洗干净的,而且洗罐子的清洁剂也不安全啊。。。
就算是本地产,运输油的油罐车也一样没人保障,想骂人了
我是洗衣机和洗碗机都要二次全部清水rinse的人,这次算是被恶心到了,以前从来没想过这个问题
costco 的大罐橄榄油难道不是瓶装好了在运来的吗
说的是食用油的上游运输链,上游大宗运输,如果海运,100%是混过舱的。你可以打电话给任何一家大型船运公司,问有没有只运输过食用油的油船,回答肯定是,No.
你说的都是真的吗? 这个打个GC很容易查出来吧。其实美国人也很热衷谈论他们油的质量。很多杂志和 you tuber 都在谈呐。
上面说了,你可以打电话问。没有一家油船公司会承诺告诉你,他家有专门只运输食用油的油船。
因为这样是无法盈利的,无法维持运营的。
船舱不洗和罐子不洗是两回事吧?燃料油和食用油的分子式完全不同。打个GCMS 应该一下就能看出来有没有被污染。当然如果不查或者有腐败那就没办法了。
你看清楚之前在说什么再问问题。没有人否认国内油罐车这个恶劣,只是补充给大家更多的信息而已。说的是大宗食用油上游运输的问题。
看看这个新闻,你觉得装运1.5万吨乌克兰葵花籽油的货轮一年的业务只给乌克兰运葵花籽油吗? 平时这么大的船就闲置着?
首批大宗乌克兰葵花籽油从克莱佩达港口启程
外媒8月18日消息:装卸公司贝加(Bega)表示,装运1.5万吨乌克兰葵花籽油的货轮将会从立陶宛的克莱佩达港发出。 该公司董事会主席Aloizas Kuzmarskis说,这是第一批通过克莱佩达港出口的大宗乌克兰食用油船货。贝加公司没有说明目的地港口,但之前的一批乌克兰食用油出口到了法国敦刻尔克港。 乌克兰是全球头号葵花油出口国。不过自2月底到7月底,乌克兰关闭黑海港口,转而通过陆路和铁路以及内河从东欧邻国出口葵花籽油。 自5月以来,乌克兰的农产品一直在运抵克莱佩达港口。不过以前贝加公司主要是小批量出口,或者与立陶宛的货物合并出口。
油船洗舱(tanker cleaning)是指为保证货油质量或修理时的安全,油船在换装油种或进厂、进坞修理前,对货油舱进行的冲洗工作。通常油船的洗舱工作是先用蒸汽熏舱,然后再用水冲洗。蒸汽熏舱时,用蒸汽灭火管系向货油舱内充满高热蒸汽,软化舱壁构件上附着的残油和油垢,然后用消防管系经过软管接上洗舱机,在货油舱内作上、下、左、右360°旋转地喷射舱壁,压力高达980 N/cm2~1570N/cm2、温度为70℃~80℃的喷射水柱即可保证使残油稀释并把铁锈、油垢冲洗掉。有些油船采用化学洗舱,亦即将化学溶剂溶于洗舱水中,使附着在舱壁构件上的残油和油垢更容易脱落,既可节省洗舱时间,又可提高洗舱质量。随着油船的大型化,每次卸油后附着在舱壁及舱内构件上的残油和油垢量是可观的,而且油垢本身也可视为一部分能源。因此,近年来原油洗舱被广泛采用。它是利用原油作为一种溶剂,在卸油期间抽回一部分原油对货油舱进行冲洗,使舱壁及构件上附着的油垢溶于原油中而被卸空,故原油洗舱被列为大型原油船防止油污的一项重要措施。凡是新建造载重量为20000t以上的原油油船,须应设置原油洗舱系统,敷设单独的洗舱管系,配备相应的甲板洗舱机或潜式洗舱机。
实用油不都是买种子回去榨,运油成本是运种子成本多少倍
食用油国际贸易中,远洋船公司好像用的是不锈钢罐体的化学品船,当然清洗不彻底的风险始终存在。
Vegetable/Palm Oil is usually transported in the international trades on board chemical tankers with stainless steel or coated tanks in segmented parcels. In the domestic and short sea trades it is often carried in smaller and less sophisticated tankers with mild steel and uncoated tanks. The risk of next cargo contamination due to inadequate previous cargo tank cleaning exists in both trades, along with the risk of regulatory non-compliance due to improper tank washings disposal to the sea.
This Risk Bulletin considers the above risks and their management and will be discussed in relation to the following:
Adherence to current standard tank cleaning procedures and independent tank cleaning guidelines in order to meet the Federation of Oils, Fats and Seeds Association International (FOSFA) requirements for tank inspection and cleanliness and shipper/charterer requirements. Compliance with MARPOL Annex II, the IBC Code (SOLAS Chap. 7) and the ISM Code (SOLAS Chap. 9) during the tank cleaning process. Observance of MMIA’s P&I insurance tank cleaning warranty and the obligation to adhere to ‘standard tank cleaning procedures’.
你这个是运原油的,一般是专门运黑乎乎的原油,船舱脏的要命,国际贸易中不可能会用来运食用油。
植物出油率一般在3-4成,榨油技术又很简单,所以直接运油成本更低
很好奇Costco的大瓶橄榄油是怎么从产地(西班牙,意大利,希腊,智力,阿根廷等)运来美国的?都是Packed in the USA.
曝光纸箱馅儿包子的记者被判入狱,希望这次曝光的人不会因此有麻烦
我去问了下。
你说错了,油船运什么油是分级的。食用油,柴油煤油,工业酒精,其他化学液体,属于同一级的。和你说的黑漆漆的原油不是一回事。
关键是都是靠运输公司自己清洗,自己检查,自己给自己打分过关。这很容易出问题。 罐装的第三方核查的还能进去看看。 船舱结构那么复杂,外行人进去看也看不明白,也不容易看出问题。
问题的关键是船舱的结构是非常复杂的,并不是一个简单球类或者罐体那种容易清洗的空间。很容易藏污纳垢:
随着油船的大型化,每次卸油后附着在舱壁及舱内构件上的残油和油垢量是可观的
进口油也是要用罐车运输到零售包装厂—除非你买几十吨用自己指定的车去码头接。 其实国内精炼的外国产油如菜籽油比国外还便宜;同学说是产业链高效。看了这个新闻才理解高效不考虑品质才有价格优势😅😅😅
不过国内的人均寿命还是很高,记得不比美国差,这又是什么原理呢?
油也不怕吧?除非去华人超市买油,否则一般超市卖的普通食用油,大豆油,还有橄榄油avocado 油这些,应该都是美国本土产的吧?
我酱油都是买Costco 大包装的日本万字酱油,也不知道是不是有机的。
美国是多人种结构,没有可比性。应该和其他亚裔人种比,日本韩国新加坡香港。美国亚裔平均寿命和日本香港接近。
老美自己给自己加料,酗酒和吸毒
中国是自己给自己加料地沟油和到处室内二手烟
如果这俩活宝国家不作死,妥妥的将近20亿高寿人口,这么好的营养条件
原油和食品油的海运,完全用的是不同的船吧
食品安全教育是个大问题。
怪不得多年前老干妈在德国查出含有矿物油污染物,网友说现在好像真相大白了。
山东鲁花发申明说他们全部是自己的专用车队运输食用油,结果网友找出几年前的新闻截屏,说鲁花没有一辆自己的油车。
根据涉事河北省油罐车的车牌号码,网友找出了该车近几年的行程路线,发现该车长期在南北之间运送各类食用油和煤油之类,涉及的食用油生产企业有几十家,多数是小食用油生产企业,大的其中还有金龙鱼湖北工厂,这个赫赫有名的食用油企业昨日发表声明,说该车为他们运输食用油的一次是该车还是新车第一次运输油品,各方面检查合格。到底是不是新车,看一下车子的注册时间就可以断定,是不是真话不得而知。
群众很愤怒,事情还在持续发酵中!
这个事情可能和当年的三聚氰胺类似,实在太不像话!
这不,关于XX集团用运输煤油的油罐车不清洗直接就装食用油,导致食用油被污染,长期食用这样含重矿物油超标的食用油,健康状况可想而知。
2017年,老干妈在德国被检出矿物油大幅超标,在大家一脸懵逼的时候,紧接着,又相继曝出海天、友加、翠宏、好人家、老干爹等多款油辣椒产品检测出含有矿物油,而且矿物油严重超标,长期食用这样超标的矿油物产品,会有致癌的风险。
来源:https://www.163.com/dy/article/J6M2JUES05565PN8.html
出事的是中国物流,这些人应该被抓起来判刑
所以老干妈算是受害者?以前一直听说老干妈质量控制很严格的
这个污染是运输环节引起的食品安全事故,其影响是广泛的,不限于一家企业一个地区。
1.海华经常回国探亲访友,大快朵颐,再说,国内家人长期生活在国内,接触概率很高 2.美国华人超市出售的国产使用植物油的食品,比如辣酱(老干妈等)、酱菜(红油酱菜),乃至曲奇饼干等等食品,都含有国产植物油。
所以以后不打算再去中国超市买零食和调料了。 正好戒了零食减肥,其它油盐酱醋可以找到日本产意大利产的平替。YouTube博主吉祥八卦兔说她在崔大舅找到的意大利醋和意大利辣酱都比国产的味道好
从老干妈等一众辣酱2017年在德国被查出矿物油(多环芳泾化合物)超标,当时老干妈还怀疑是使用了橡胶垫圈所致,现在好像真相大白了,也揭示了这个食品安全事故的影响之广泛。
这个可能就是一些司机不洗车的重要原因吧?
加拿大卖方也要求油罐车提供上次运输货物品种的文件和清洗证明
各种国产snack也应该是吧。
"《食品安全法》和《食用植物油散装运输规范》,明确规定运输散装食用油使用专用车辆,不得使用非食用油罐车或容器运输。"
装过非食用油的油罐车,根本不能再装食用油,哪怕彻底清洗。油罐车就应该分两大类,运输食用液体或者非食用液体。运输食用液体的槽车一般是不锈钢材料制成,美国高速上经常看到,外观整体亮闪闪的,非常干净漂亮。
同样是食用油,如果从运输大豆油换成花生油,那么清洗一下再运是没有问题的。非食用液体罐车运输食品必须被严格禁止,不是清洗不清洗的问题。
自己榨油一定要注意原料的干净和新鲜程度.
尤其建议不要购买农村小油坊制作的散装花生油,因为小油坊主要购买去壳花生仁,编织袋装,远途运输,花生衣容易破损,加上存放空间、条件的限制,容易发霉,榨出来的散装花生油黄曲霉毒素的污染程度相对较高,危险性较大。
就我前面回帖说的,中储粮不错是卖方,可它自己难道不比洗地的网友更知道自己是卖方吗, 那它怎么不敢撇清,只敢说要自查呢。 拿有的网友说的,如果来一辆粪车,难道你也直接装运吗。 另外,记者追踪了几辆车,其中一辆去了陕西勉县,勉县当地已经成立工作组调查检测,而且勉县市监局的工作人员说了,涉事罐车是中储粮方面找的。 各个环节的责任与利益链条怎么回事,他们自己清清楚楚的。
零食里的油呢?
如果是正规食品企业,原料供应商资质都是要审核的,运输和清洗程序也是要验证的,收货商会要求提供相关声明或者现场审计。如果是已经通过ISO或者GDP认证的运输商,一般可信度比较高。最终的风险和追责都在食品生产商身上,质量部门就是干这个活的。
美国罐车分为食品级液体罐车(牛奶,食用油等)和其他液体罐车(化工原料、石油产品等),两类车辆严禁混用,不存在煤油车清洗后改运食用花生油的情形(这个情况估计美国从业者打破脑袋也想不到)。同类食品级罐车混运不同液体,比如一会儿运大豆油,之后清洗后再运玉米油的情况是常见的,量大的液体往往是专门用于该类液体的罐车,比如专门运输牛奶的罐车。
美国食用油运输的担心,其专业程度不是一个层级的:
Common Concerns During Vegetable Oil Transport Quality degradation is one of the most significant challenges of transporting vegetable oil in bulk. Edible oils undergo chemical changes during transport, which alter their appearance and flavor. In some cases, these chemical changes result in several public health hazards.
Oxidation Oxidation occurs when oil is exposed to oxygen, among other substances, which hastens the rate of degradation, resulting in its rancidity. When this happens, the oil starts to develop undesirable flavors and odors, which can be rectified with additional processing but will also incur additional costs.
Although all oils are always in a state of oxidation, which is quickened as the degree of unsaturation increases, the rate of oxidation is decreased considerably when the right conditions are present when transporting oil in bulk. Meanwhile, this rate is increased due to the following:
Contact with Air. Unsaturated fats have carbon-carbon double bonds that can be broken by oxygen in the air during the process of oxidation.

Hydrolysis reactions can occur during bulk edible oil transport when tanks are improperly cleaned. The presence of water molecules in the tank breaks down oils to become fatty acids, rendering them unusable for typical household applications such as cooking.
Contamination Contaminants can make their way into edible oils being transported through several channels. They can be introduced through residue after improper cleaning of the tank or during processing and can drastically impact product quality and safety. The following are common contaminants found when transporting vegetable oil in bulk:
Farm Chemicals (pesticide residue) Debris (dust, dirt, small sticks, vegetable matter, etc.) Hydrocarbons Tank Coatings
Key Areas of Focus When Shipping Cooking Oil in Bulk Bulk liquid transport is the go-to method of vegetable oil transport for large-scale food processing, manufacturing, and other industrial processes. The top benefits of bulk liquid transport of edible oils include:
Versatility Sustainability Ease-of-Transport Efficiency
Cost-Effectiveness However, there are still numerous considerations to run through for vegetable oil transport in bulk. Consider the following:
Temperature. Vegetable oils are typically kept under specific temperatures to maintain viscosity during loading, transport, and unloading. In some cases, heating coils are used for equal heat distribution. However, make sure not to supply too much heat as it could result in the oil turning rancid. Type of Tank.

Flexitanks offer a significant advantage in this regard because they are single-use, eliminating any possibility of contamination. Transportation Rules. Countless rules and regulations for transporting vegetable oils need to be accounted for to avoid any issues while in transit.

说实话,如果不是这次新闻,我也想不到会有人把能入口的和不能入口的混在一起装。 他们是觉得自己家绝对不会吃的吗。。
你都不知道吧,现在国内养鸡鸭户只吃自己单独养的,种水果的会留几颗单独照料的树给自己吃,卖菜的也一样,全是高科技,我前阵子回国算是见识到了。 所以油啊,醋啊酱油之类的也都有专供吧
但是不是玉米大豆菜籽油并不太好吗?农村都是这种油。
谢谢这个信息!
这次骂新京报不是因为揭露事件,而是它揭露事件的目的让人感觉有些不纯粹。 首先是他们的跟踪调查是几个月之前了,结果到现在才发,那这些混杂工业油的食用油早已散布市场了。如果他们那么关心民众健康,不是应该尽快的让其他民众知道这件事吗?如果说是为了新闻严谨性,那么他们费了几个月才发的新闻应该包含后续这些油脂的买方是谁,如何进入食用油市场的。 其次,他们在视频中给罐车的车牌打码,让其他人无法通过查询车辆行程信息来确定买方。如果他们那么关心民众健康,不是应该让民众知道卷入事件的食用油生产厂家吗?
掩耳盗铃,揪着新京报能解决问题吗?跟解决不了问题就解决提出问题的人有啥区别?!
这又不是个别现象,而是延续多年的食品运输行业普遍问题。不建立有效的监管,不立法专车专用,不提高司机待遇,不减少过路费税费,就解决不了这个普遍存在的问题。而这些问题估计短时间也解决不了!
国内这毒空气毒食品是逃无可逃,一次比一次惊悚。

这么说的脑子呢? 明知道最后会砸自己脚,还发出来给人clue? 难道不是发现会有引火烧身的风险直接闷声不提? 金龙鱼这次绝对难逃其咎,但是中储粮一样脱不了干系。扯什么国资外企纯就是为了转移公众注意力。老百姓最关心的是油本身,不是宫斗
他们打码,他们不明说买方,也没影响神通广大的网友火眼晶晶查出来下家啊。 这年头,谁低估网友就是搬起石头砸自己的脚。 他们如果不打码,想骂他们的,还是会说他们坏心眼,司机难道是关键人物吗,却把司机推到风口浪尖上。 这件事就不能关注事实吗?事实就是新京报揭露的是事实。我才不想管他们背后的目的背后的资本呢。 跟反腐也可以靠小三一样。 难道就因为要爱国就得吃这种油吗。
你说的对,苏丹红的时候我就想过你说的这些, 但是我觉得养鸭子的只能保证自己吃到正常的鸭子, 种水果的只能保证自己吃到没农药的水果, 但是他们就不吃其他市场上流通的东西了吗。 满世界都是坑,我相信总有一坑他们会掉下去。 因为他们也就是我这样的普通人,他们也没有样样特供的资格啊。
新京报曝光混装问题我是感激的,但是它选择性的曝光也是该骂的。
求全责备不是解决问题的有效手段。假如每个人每个单位都要面面俱到就别干事了。
现实是需要抓大放小,才可能解决普遍性的问题。
有国外罐装的,很贵
结论总有办法引导到: “西方亡我之心不死”,无一例外。
正规公司会有专门的shipping validation,条件都是验证过的。运输过程中,温度湿度控制都有专门的随批记录设备,收货方会验收。但在规章制度不完善的地方,就只能靠人的良心了。
益海嘉里是马来郭家的,金龙鱼胡姬花都是他家的。郭家和香港霍家一样,ccp的老朋友、红顶商人,而且在马国影响力巨大,所以出多少事都没关系。现在微博上义和团造谣说益海嘉里是外资、甚至有直接栽赃说是美资的,反正啥都怪美国就是了。 中储粮就是以前的粮管所系统,前几年卖发霉玉米小麦都不了了之了。别人从它这里买油,有些是它安排运输、有些是买家安排,罐车出事它肯定有责任。 总之买家卖家都是国家的人,最后估计推出几个小运输公司出来担责。
现在微博上好多说新京报是美资、故意造谣的
或许是新京报调查几月发现这事后台不得了,不敢指名道姓。
是2015年湖南卫视的记者东西,然后新京报的实习记者拿着资料去拍的,只是不知道现在网络传播这么块。最早的话,2005年就有报道,基本上就是过几年,给你一个任务去拍,当作入行。 更深层次的来说,最早是湖南的记者在研究,为什么湘菜火,特别是只用猪油的才特别火。
发现湘菜流行有一个特点,比如辣椒炒肉的油,是猪肥肉现炸油的,现在全国都是很火,是因为猪油好吃吗?所以顺便去看其他的油,结果整出这么一个。
油这个可能能分开,很多时候分不了,比如运煤的船也可能下一趟是运大豆,是靠洗的。
报道的真实性应该是讨论重点吧。如果是虚假的,支持打假。如果是真实的,却不讨论新闻内容,反而是针对新闻时间,爆新闻的动机,就很值得三思其目的了。
所以还是那句话,不解决问题,解决发现问题的人。
你大学的时候是哪年?我看最早报道是2005年,会不会发生的更早?
这明显又是一起党务系统和国务院系统打架的事件。这样的事情最近已经发生好几起了。比如国务院刚提出促进股市的措施,中宣部出版局的游戏新规就导致股价暴跌。比如国务院要吸引外资,国安部就鼓励抓间谍。蔡奇这个人野心不小。

所以金龙鱼是因为和共产党关系良好?那小粉红骂的那么凶,骂的是自己人? 哈,那回头打脸会不会疼啊。
