Sausage, ham: how processed meat is made and the way it’s linked with most cancers – 01/08/2022

Sausage, bratwurst and bacon could even share house with lizard, duck and butcher’s arduous shank, however not like chilly cuts, these meals are usually not meat. in nature. Like ham, turkey breast, salami and sausage, they’re examples of so-called processed meats.

“Most processed meats comprise pork or beef, however they’ll additionally comprise poultry and organ meats akin to liver, or organ meats akin to blood,” differentiates Dirce Maria Lobo Marchioni, FSP/USP Diet Professor (Division of Public Well being, Solar College). – Paulo).

Mixing of meat is allowed whether it is supplied for by the technical rules. In response to Marisa Aparecida Rodríguez Pollonio of the College of Meals Engineering at Unicamp (State College of Campinas), all meat processed in Brazil that has handed inspection meets the identification and high quality requirements outlined by the Product Id and High quality Technical Laws, or RTIQ. , animal origin.

These requirements are regulated by the Ministry of Agriculture, Livestock and Provide and authorised by legislatures akin to Anvisa (Nationwide Well being Surveillance Company).

Though processed meat is protected from a well being standpoint, it may be excessive in sodium and fats. Earlier than they attain the fridges, they’re processed by means of procedures that improve the style or enhance its preservation, together with salting, canning (including salt), fermentation and smoking (exposing meals to smoke) – therefore the nomenclature “processed”.

A few of these manufacturing steps, akin to including preservatives, may also hurt the physique. In 2015, the Worldwide Company for Analysis on Most cancers (IARC), a part of the WHO (World Well being Group), added processed meat to its checklist of group 1 carcinogens for which there’s already ample proof of a hyperlink to most cancers. For instance.

stay effectively listened to meals engineers, nutritionists and physicians to elucidate how processed meat is made and why overconsumption of it could enhance the chance of power illness.

More often than not, sausages are comprised of much less noble cuts of meat.

Mortadella and sausages: meat, trimmings and additions

Within the preparation of sausages and sausages, much less noble cuts of meat (“second” meat) are often used. So-called “mechanically deboned meat”, CMS, that’s, bones and carcasses of poultry, cattle or pigs which have been deboned and changed into uncooked supplies for the manufacturing of processed meat, can be used.

These bones and carcasses have to be authorised by the SIF (Federal Inspection Service) for human consumption. Jennifer Medeiros Campos Guerra, nutritionist and researcher on the Animal Lab at UFPE (Federal College of Pernambuco), explains that the trade is utilizing CMS to cut back the price of sausages and keep away from meat waste that might not be eliminated by hand in slaughterhouses.

“When you think about cattle weighing 500 kg, there may be often a chunk of meat that will get caught within the carcass after the cuts have been made. cash, so the trade makes use of this meat connected to the bones,” says the meat specialist.

These cuts are crushed and frozen, positioned in a tool known as a “cutter” after which blended with ice, salt, and components akin to nitrites and phosphates. Starch and vegetable proteins may be added.

The elements are then blended to kind a liquid mass (technically referred to as an emulsion) which consists of a combination of meat with the moisture of its fats, water, salt and components.

Lastly, the combination is stuffed, that’s, launched, into an acceptable wrapper, which can be, for instance, the intestines of a bull. The drug is ready and cooled for commercialization.

Ham is obtained from a part of the muscle, and ham is a combination

In response to Guerra, ham is the one processed meat that doesn’t embody meat mixtures: it’s comprised of pork muscle. Ham additionally contains varied forms of meat.

Each ham and ham are restructured pork merchandise which can be brine. “It is like once we need to season a complete piece of ham at dwelling and depart it in a single day on this marinade,” compares Pollonio, professor at Unicamp.

This brine is utilized to the ham items by injection on the calculated weight. After that, the cuts enter the gear, the place “tipping steps” happen to distribute the components contained in the muscular tissues of the animals.

Parts are embedded and positioned in particular codecs for cooking. They’re then unwrapped and packaged and could be offered in slices.

Hamburger, bacon and breading

Field hamburgers accessible in supermarkets are meat merchandise made completely from several types of meat. They might or could not comprise seasoning, are molded and frozen.

The origin of bacon is pork stomach meat. A part of the pork is salted and smoked, typically uncovered to synthetic smoke.

Within the case of breaded merchandise akin to nuggets, the start line is the substrate, which could be a marinated complete fillet or a restructured uncooked materials.

“They get the addition of layers referred to as pre-dust, dough and breading, that are much like artisanal breading processes, however with far more stability and security,” Pollonio describes.

Uncooked meat is used for manufacturing – in Brazil, primarily pork and beef. They’re crushed with salt and a few components and wrapped in permeable wrappers.

In air-conditioned chambers with temperature and relative humidity management, the fermentation course of takes place with managed acidification and drying to roughly 30% of the unique weight. This enables the salami to be steady for storage outdoors of the fridge. “But when it is sliced, it must be refrigerated,” says Pollonio.

There are additionally recent meals (which must be refrigerated) or frozen meals akin to sausages, pickled cuts, Christmas birds, and frozen loins. They’re seasoned, cooked to their identification normal, and offered.

What are the well being dangers

Iarc (Worldwide Company for Analysis on Most cancers), a division of the WHO, revealed a big examine in 2018 that concluded the human carcinogenic danger of consuming purple meat and processed meat.

MarchioniSure FSP-USP, explains that sure meat processing steps, akin to salting and smoking, can result in the formation of carcinogenic chemical substances, together with N-nitroso compounds and polycyclic fragrant hydrocarbons.

Carcinogenic compounds, says the researcher, bind to kind compounds (adducts), which, if left uncorrected, trigger mutations.

As well as, processed meats could comprise components apart from salt, akin to color-fixing compounds (nitrates), that are unhealthy.

Such substances are used within the meals trade to restrict the expansion of dangerous micro organism. Nitrites and nitrates by themselves are usually not carcinogenic. Each are pure chemical compounds that comprise nitrogen and oxygen and are current in water, soil, and greens akin to beets and spinach.

The issue is that when interacting with some compounds, akin to amino acids (present in proteins), they’ll kind substances which can be dangerous to well being, akin to carcinogenic nitrosamines.

Correctly, Marchioni explains, nature has made most nitrate-rich greens additionally wealthy in antioxidants (vitamin C, vitamin E, and polyphenols) that stop undesirable chemical reactions that processed meals cannot.

Though regulators world wide place limits on the addition of those compounds – in Brazil, for instance, it’s 150 mg per kilogram of meals – the overconsumption of processed meat is a priority.

Fabio Guilherme Campos, former president and full member of the SBP (Brazilian Society of Proctology), notes that bowel most cancers is the results of the interplay of two elements, genetic and behavioral – the latter pertains to meals.

“The breakdown of processed meat fats within the intestines can result in the formation of some substances which can be dangerous to the physique, so in case you eat a whole lot of fats and little fiber, you’ll not generate short-chain fatty acids, that are protecting, and all through your life. there might be an imbalance,” he says, who can be a professor on the USP Faculty of Drugs.

Along with growing the chance of sure forms of most cancers, consuming processed meats may enhance the chance of different power illnesses, akin to stroke and sort 2 diabetes, relying on the quantity of fats and sodium.

While you purchase a meat product, you need to eat meat, however what you are truly consuming is a sure proportion of protein, water, salt, and fats. Jennifer Medeiros Campos Guerra, nutritionist and researcher

The Inca (Nationwide Most cancers Institute), affiliated with the Division of Well being, recommends that you just utterly keep away from or at the least scale back your consumption of any such animal protein.

“For instance, thrice every week is an exaggeration,” Campos analyzes.
