In the cold winter, there is nothing more refreshing than eating a hot pot. However, a hot pot restaurant under a catering brand was exposed to the problem of "duck meat mixed with mutton rolls". After so many years of hot pot, I really didn't know that what I ate might be fake mutton. So how can we tell the real mutton roll from the fake?Where does the smell of mutton come from?
Why does mutton smell bad?
Lamb is widely consumed, but some people may be uncomfortable with its natural smell. So, where does the smell of lamb come from?
In fact, the smell of mutton mainly comes from the fat on the sheep's body, that is, the fat tissue. It is related to dozens of components, the more typical ones are 4-methylcaprylic acid, 4-ethylcaprylic acid and 4-methylnonanoic acid, and the first two components play a major role. During digestion, the food is fermented by microorganisms in the rumen of the sheep, and then turned into fatty acids deposited in the adipose tissue of the mutton, which forms this special smell.
And about the strength of this smell, sheep are not quite the same as sheep. Generally, the smell of rams is heavier, while the smell of castrated sheep (įž¯sheep) will be reduced;The smell of adult sheep is more pronounced than that of lambs, because the older the sheep is, the more fat they accumulate on their body, the more fat they will become. Smell is also related to hormone secretion levels and metabolism.
How to distinguish a real mutton roll from a fake?
Since the smell of mutton comes from fat, some unscrupulous merchants will mix some mutton fat with duck meat with relatively low cost and very similar taste and appearance to mutton, and smoke the fake meat that originally had no mutton flavor with a hint of mutton to pass it off as mutton. Of course, a single piece of mutton is certainly not easy to adulterate, so adulteration is often concentrated in meat products that need to be reprocessed, such as mutton rolls. So, how do we distinguish a real mutton roll from a fake?
It is understood that usually the ** of the mutton roll is 1 of the mutton5 times or so, so too cheap lamb rolls will be at risk of adulteration. In addition to **, how do we distinguish from the color and texture of the meat?For this reason, a comparative test of real and fake mutton rolls was made.
Real mutton, using lamb leg meat and lamb fat rolled together;For fake lamb, the skinless duck breast and sheep's tail oil are rolled together. Once rolled, put both types of meat in the refrigerator and freeze them. After 1 day, cut the frozen meat into rolls. As you can see from the image below, both rolls do not fall apart, but the rolls made with duck meat do not have any noticeable lines, while the lamb rolls have clear and natural lines.
When the two meat rolls are thawed, the real and fake are immediately visible. The lamb roll is basically complete, and you can see the lean meat with fat, and the red and white meat sticking to each other.
And the duck meat rolls are separated as soon as they are clamped, white to white, red to red.
Finally, place the two types of meat rolls in a pot and soak them. After the mutton roll is cooked, it will shrink into a ball, the color is relatively natural, the clamp is not scattered, the meat is firm, it tastes soft and tender, and the mutton flavor is very strong.
The duck meat rolls are easy to spread out as soon as they are cooked, and they are broken with chopsticks, although they have a smell, but you can clearly feel the taste of the meat is different. If you use the spicy butter pot bottom, you may not be able to eat it, but if you use the clear soup shabu, you can eat it in one bite.
Bulk lamb rolls are relatively easy to distinguish, and how to distinguish the real from the fake packaged lamb rolls in the supermarket?
Packaged mutton rolls are divided into pure mutton rolls, conditioned mutton rolls, mutton flavor rolls, etc.
The so-called conditioned mutton rolls and mutton flavor rolls are a category, and the standards it implements are mostly SB T 10379-2012 "quick-frozen prepared food" and SB T 10482-2008 "Quality and Safety Requirements for Prepared Meat Food", and in addition to mutton, other raw meat is also marked in the ingredient list.
For pure mutton rolls, it is necessary to look for the implementation of the standard GB 2707-2016 "National Food Safety Standard Fresh (Frozen) Livestock and Poultry Products", and only mutton is in the ingredient list.
Therefore, when you buy pre-packaged lamb rolls, you should carefully check the meat ingredients marked in the ingredient list.
In fact, mixed meat rolls are theoretically not harmful to the human body, so there is no ban on production and marketing in China at present. However, this does not mean that some merchants can sell duck meat on the head of a sheep. If the sale is a mixed meat roll, the manufacturer must mark it according to the law, and the merchant must clearly inform it.
This winter. Have you eaten the mutton shabu?
