You are in a store or supermarket. The shopping list has eggs. In front of you on the shelves, as usual, the three most common categories of eggs: the second category table - is the cheapest; The first category is the dining room - a bit more expensive; Choice table egg - is even more expensive. Other categories we are less common and not everywhere. They do not take into account.
Attention to the question: which category is most advantageous to buy eggs? We all checked out, everything felt and now share with you the findings.
State Standard and Reality
egg grading regulated by Category complies with GOST. Determining the category parameter is the mass of the egg (the sixth page of the document via the link).
- The second category: 45-54,9 grams.
- The first category: 55-64,9 grams.
- Choice: 65-74,9 grams.
However, it is the norm. whether it is observed in practice? Often you hear the words of the older people in the style of "here and cheat, sell second grade as a Picking". We went to the store and made test purchases. A dozen eggs each category.
With culinary scales we weighed eggs each category.
The results of the second category:
Total weight was 509 grams of a dozen, that is an average of one egg weighs 50.9 grams. It's almost the middle of the rules on state standards. Everything is good.
The first category:
Total weight was 595 grams of a dozen. The average weight of an egg - 59.5 grams. Again the middle of the norm. Things are good.
Selective egg:
Total weight was 665 grams of a dozen. The average weight of an egg - 66.5 grams. Hmmm ...
According to GOST minimum mass of selected eggs may be 65 grams. It turns out that in practice we inherited ten-picking is actually on the lower limit of normal. More 1.5 grams, and could ask questions of the poultry farm.
Ideally, one should be selective egg weigh an average of 70 grams. With this ten-picking, we sustained a loss of about 35 grams of the product.
Saving
We now turn to the financial side of the issue. Our average price shopping for eggs is as follows:
- The second category: 53 rubles per dozen.
- First category: 59 rubles per dozen.
- Choice: 63 rubles per dozen.
To begin, we calculate the price of 1 gram of eggs in each category.
- The second category: 53 = 0.1041 ÷ 509 rubles per gram.
- First category: 59 = 0.0992 ÷ 595 rubles per gram.
- Choice: 63 ÷ 665 = 0.0947 rubles per gram.
As you can see, gram eggs cheapest choice, but very often, people try to save money and take the second category of eggs because they're kind of like the cheapest. In fact, it is most advantageous to take Picking. Let it be more expensive, but the relation to the product gets a lot Picking the most profitable.
Now let's spend in Central more visual form. We rely on the second category. Denote the average actual weight of the eggs of the second category as the x.
Then the average actual weight of the eggs of the first relative to the second category will be 59,5 ÷ 50,6 = 1,17h. Hence, the price must be ten 1,17 × 53 = 62.01 Ruble. But in practice, these dozen eggs costs only 59 rubles.
The average actual weight of selected eggs relative to the second category of 66,5 ÷ 50,6 = 1.3x. So, the price for a dozen should be 1.3 × 53 = 68.9 rubles. But in practice, only 63 rubles.
in total
It turns out that buying-picking instead of the second category, we save 68.9 - 63 = 5.9 rubles each dozen eggs.
I am engaged in power sports, and is important to me to fulfill the daily norm of a protein, which, incidentally, is not less than 1.7 grams per kilogram of body weight per day. With this calculation even eaten 10 eggs a day will not solve the problem of lack of protein, but because the more a single egg, the better.
Let's see how much I save if I every day for a year to buy a dozen eggs instead chosen the second category.
5,9 × 365 2 = 153.5 Ruble savings per year. Not bad!
Once again about the damage to the eggs
Modern research has unequivocally denied the link between the consumption of eggs (as well as other saturated animal fats and cholesterol foods) and increase bad cholesterol in the blood. It was found that a protein found in eggs, on the contrary helps to establish a process of cholesterol transport in the body and prevent the formation of plaques and blood clots. In fact, the lack of protein in the diet is much more terrible than a reasonable amount of excess saturated fats. Our article "With or without the yolk?
