Calorie content and chemical composition of Simirenko apples
Small greenish fruits with juicy crunchy flesh and a pleasant apple smell, which are still found in apple orchards and on store shelves, are Renet Simirenko apples. The article will introduce the description of fruits, vitamin compositions and the benefits of apples of this variety.
Characteristics and description of the variety Simirenko
To exclude numerous errors in the name, we immediately clarify: correctly this variety is called Renet Simirenko (and not Semerenko), and under that name it was included in the State Register of the Russian Federation in 1947. During this time, new varieties failed to supplant the Simirenko variety. It is still popular and recommended for cultivation in the North Caucasus and Lower Volga regions.
Did you know? Fresh apples of the Renet Simirenko variety are sent to the astronauts aboard the space station and are used to prepare astronauts' meals. Therefore, they are called cosmic.
The most favorable conditions for growing Renet Simirenko are mild winters and fertile soils, which corresponds to fruit zones - steppe, forest-steppe, woodland. In Russia, this variety brings the best crops in the Krasnodar Territory, the Kuban and adjacent regions.
The variety is winter and ripens in late September. Fruits are rounded flattened, light green or densely green in color when picked up. In the southern regions, when there is plenty of sun, a slight pink blush is possible. The fruit weighs 120–150 g, the largest - 200 g. The flesh is white, a greenish tint is possible, juicy, dense. The taste is sweet and sour. The marketability of fruits is estimated at 90%.
A distinctive feature of the variety is the presence on the fruits of 2-3 rusted warty growths up to 7 mm. The fruits are stored for a long time (up to six months), over time, the peel becomes yellow, and the flesh becomes grainy and loose. Vitamin and mineral composition changes slightly if storage rules are followed.
Chemical and vitamin composition
The vitamin profile of Renet Simirenko is represented by vitamins A, B1, B2, B5, B6, B9, C, E, H, PP. Fruits are rich in natural sugars, fiber, pectin, phytoncides, healthy acids, which give the fruit a sour taste with vitamin C. These are organic acids - malic, citric, formic, tartaric, chlorogenic, ursolic and volatile fatty carboxylic acids.

- fats - 0.4 g (0.7%);
- carbohydrates - 9 g (4.3%).
For those who calculate the calorie content of the diet and lead a healthy lifestyle, information on the ratio of calories, fruit size and weight of 1 pc is useful:
- diameter 5 cm, weight 95 g - 35.15 kcal;
- diameter 6.5 cm, weight 135 g - 49.95 kcal;
- diameter 7.5 cm, weight 180 g - 66.6 kcal;
- diameter 12 cm, weight 220 g - 81.4 kcal.
Important! The calorie content of two apples per day corresponds to the calorie content of the recommended snack or a third of a full dinner.
Useful properties of apples for the body
Due to the long shelf life, Simirenko apples are available almost all year round and are universal in terms of consumption. Apples are recommended for children as the first food, so the first plant product a person meets is an apple. Baked fruits are used for gastrointestinal tract diseases, and juices and fresh apples from green apples are widely used in fitness centers.
Apples can be considered an ideal dietary product - they allow you to eat less, - dulling the feeling of hunger, and at the same time lose weight, - normalizing metabolic processes. Low calorie content allows you to include them even in the most stringent diets along with other products.
The dense pulp of fruits indicates the presence of plant fiber - 4 g per 100 g of product. Such a content of dietary fiber and the rate of assimilation of natural carbohydrates by the body provide apples with a glycemic index of 30. They relate to products with a low glycemic index (GI).
For comparison, GI honey - 90, watermelon - 72. Fiber fibers of the dense pulp of the fruit like a toothbrush clean teeth from plaque and disinfect the oral cavity, which helps to prevent caries. A weak malic acid does not affect the enamel and normalizes the acidity in the mouth.
Pectin constitutes half the amount of dietary fiber, an important carbohydrate compound for normalizing the functioning of the cardiovascular system. Pectins bind toxins, remove excess cholesterol and heavy metals from the liver, cleanse the intestines and prevent constipation.
Important! American researchers have proven that a daily intake of 200 g of apple juice reduces the risk of developing dementia (senile dementia) by several times.
A low sugar content allows you to relieve the circulatory system, normalize blood glucose and lower cholesterol during an apple diet by 30%. By provoking the secretion of gastric juice, fruits accelerate the digestion process and are one of the best sources of dietary iron, which is responsible for the condition of the hair, skin and the production of hemoglobin. They are recommended to be included in the diet of young children and people suffering from iron deficiency anemia.
The largest amount of nutrients is found in the peel of apples and in the pulp directly below it (5 times higher), so try not to deprive yourself of such an amount of valuable vitamins and minerals by peeling fruits. But this applies to environmentally friendly products. It is in the peel of apples that the largest number of antioxidants is concentrated, which have antitumor and anti-aging effects (hence the term “rejuvenating apples”).
Juices by the content of vitamins are, as a rule, poorer than the fruits themselves, but with prolonged storage, the loss of nutrients occurs with them. So the loss of vitamin C in the preparation of juice is 50-60%, and when storing fruits for up to 6 months - 25%.
It is the sweet and sour taste of Simirenka fruits that indicates the presence of a high content of catechins - P-active substances from the category of bioflavonoids, which are distinguished by a strong antioxidant effect and are necessary to normalize the functioning of the heart and kidneys.
Important! Polyphenols, plant pigments that are powerful antioxidants, cause darkening of fruits on a section. Unfortunately, their number in a green apple is less than in fruits with a bright color.
There are two times less fruit sugar in Simirenko’s green-colored fruits than in varieties with a red peel, so they can be recommended for patients with diabetes. With a tendency to allergies, only green apples should be consumed, since the hypoallergenicity of green fruits is lower than red ones. Green apples are also useful for those who have low acidity in their stomachs.
A set of organic acids cope with this problem. The seeds contain the antitumor vitamin B17, known as letril or amygdalin, so the seeds are more useful than harmful with moderate consumption. Hard fruits with a hard thick peel are perfect for cooking: baking and stuffing, they do not burst in the oven.
Possible contraindications for use
The harm of apples is insignificant and manifests itself mainly with improper consumption. A universal contraindication is individual intolerance to the product. Patients with aspirin intolerance are not recommended to consume acidic fruits due to the presence of salicylates in them.
Plant fiber, with its general benefits and malic acids, can cause exacerbation of colitis, gastritis and other inflammatory diseases of the gastrointestinal tract. Uncontrolled intake of fruits can cause flatulence and bloating. In such cases, it is advisable to peel the apple.
Did you know? There are about 7,000 varieties of apples, but only 100 are grown for consumption, the rest are used as technical and decorative. The height of the apple tree, depending on the variety, can be 12 m and 60 cm, and the size of the fruit ranges from 1 cm to 15 cm in diameter.
Nutritionists recommend consuming no more than 400 grams of apples per day with a normal diet to avoid unwanted problems. Among all the abundance and variety of varieties, green apples are considered the most useful. Eating one apple a day, you will provide yourself with a set of vitamin and mineral substances that the body needs so much for vigorous activity.
