What beneficial substances are contained in lemon?

Calorie intake per day

As such, there is no single and generally accepted daily calorie intake. According to the recommendations of the World Health Organization, “energy entering the body (in calories) must be balanced with energy expended.” Thus, your individual calorie intake depends, first of all, on the nature of your work, level of physical activity, gender, age and a number of other factors. However, on the Internet you can find many tables and calculators of unknown origin, offering information on daily values, supposedly based on authoritative sources. We believe that the quality of this information is quite questionable.

The most reliable way to determine individual calorie needs is to simply calculate the energy value of food consumed during the day (or several days). Just record your normal daily diet on paper. Write down what and how much you ate during the day. Calorie content can be directly calculated using information from product labels and using our website. Provided that you are healthy and your weight does not change much with your current diet, the results obtained can be conditionally considered your daily norm.

To lose weight, you need to slightly reduce your daily energy intake. If you maintain your current lifestyle, you will experience a slight calorie deficit because your costs will remain the same. This will lead to the gradual burning of your fat reserves. What exactly the deficit should be is up to you to decide. We strongly advise against increasing it sharply, because... it won't lead to anything good. Reduce your calorie intake gradually and lose weight slowly. This way you won’t have to torture yourself and break down from time to time. And of course, before making any dietary changes, we strongly recommend that you consult with your doctor or qualified dietitian.

Citric acid - benefits and harms

Citric acid is found in half of all food products and has a wide range of beneficial properties, but can also negatively affect health. People who care about their health are interested in the benefits and harms of citric acid. This should be looked into in more detail.

Chemical properties of citric acid

The white matter can be classified as a natural or synthetic antioxidant. When heated above 175°C, it breaks down into water and carbon dioxide. Citric acid has a low level of toxicity, dissolves quickly and mixes well with other chemicals. It is worth noting that it is environmentally friendly. The composition of citric acid depends on the extraction method. It is found in citrus fruits, pine needles, berries, shag stems, etc. But today it is not profitable to obtain acid from fruits. Therefore, it is synthesized from sugar-containing products (sugar, sugar beets, molasses, sugar cane) by fermentation in the culture liquid of certain fungi of the genus Aspergillus and Penicillium.

What are the benefits of citric acid?

1. In cooking, this substance is called food additive E330-E333. It gives products a sweetish taste and acts as an antioxidant. The substance is absolutely safe for health in moderate quantities.

Solutions that are too saturated can cause skin irritation, especially in people with sensitive skin. Irritation of the mucous membranes of the stomach may also occur. It is important to remember that it is not advisable to inhale dry citric acid, so as not to provoke irritation of the respiratory tract.

Citric acid is a very valuable product, but it is useful in moderation. Therefore, it is not recommended to use it separately from food products. The only exception is the fruits that contain it.

What are the benefits of Lemon?

• Vitamin C
  is involved in redox reactions, the functioning of the immune system, and promotes the absorption of iron. Deficiency leads to loose and bleeding gums, nosebleeds due to increased permeability and fragility of blood capillaries.
• Copper
  is part of enzymes that have redox activity and are involved in the metabolism of iron, stimulates the absorption of proteins and carbohydrates. Participates in the processes of providing oxygen to the tissues of the human body. Deficiency is manifested by disturbances in the formation of the cardiovascular system and skeleton, and the development of connective tissue dysplasia.

How to dissolve correctly? Product price

Citric acid is a food product in powder form that is freely sold in all stores. It is packaged in packages of different sizes and can cost from 20 to 30 Russian rubles per 50 grams.

If a culinary recipe specifies this or that amount of citric acid, then before adding the powder to the dish, it is recommended to dissolve it. As a rule, ordinary drinking water is used for this. The resulting solution is added to cream, sauce or dough. By the way, in the case of the latter application, citric acid is used for a reason, but to extinguish table soda. If you dilute the powder substance correctly, you can get very fluffy, tasty and aromatic baked goods.

What is this substance and what is it made from?

Citric acid is a chemically produced powder. It is a tribasic carbonic organic compound. It looks like a scattering of small white crystals. It has a pronounced sour taste and no odor.

Let's find out what citric acid is made from:

• More than 200 years ago, it was first obtained by a Swedish pharmacist, isolating it from lemon juice and using calcium;
• Almost a hundred years later, English scientists learned to make a substance from calcium citrate. The juice of unripe lemons was combined with quicklime, and the resulting salts were crystallized. As a result, the desired powder was obtained, but in very small quantities. The method was expensive and labor-intensive, so people tried to figure out how to make citric acid differently;
• Towards the beginning of the 20th century, chemists discovered an enzymatic method for extracting a product from penicillin mushrooms. The substance was made from carbohydrate compounds, affecting them with mold fungi. The method was good, but extremely difficult in terms of purifying the final product;
• Surely you are interested in how citric acid is made today. The main production method is also biosynthesis; corn, sweet potatoes, cassava and even agricultural waste are used as raw materials. Cleaning is done with activated carbon.

Citric acid is found in almost every living organism! Most of it is in citrus fruits, in berries - raspberries, cranberries, strawberries, black currants, tomatoes, pineapples and apples.

During the production process, food and technical products are made, the difference between them is only in the degree of purification.

Product properties

So, we have found out what edible citric acid is made from, and then we will consider its composition and properties.

The chemical formula of the powder is (HOOCCH2)2C(OH)COOH. The product is highly soluble in water or ethyl alcohol and melts at 153 degrees Celsius. When heated, it decomposes into aconitic and oxalic acids. If you shine an ultraviolet lamp on citric acid, it glows greenish. Calorie content of 100 g of powder is only 1 Kcal.

The composition of food citric acid is represented by 2-hydroxypropane-1,2,3-tricarboxylic acid and 3-hydroxy-3-carboxypentanedioic acid.
