About the book: 1969 / Fruits and vegetables are necessary for a person all year round and should be included in the daily diet. They contain important elements of our food: vitamins, proteins, carbohydrates, acids, enzymes, flavoring and aromatic substances. They contribute to more complete absorption of food, and consequently, the preservation of health and performance. However, the consumption of fresh fruits and vegetables is limited by their ripening period. To ensure the consumption of these products throughout the year, they are canned. And here it is very important to preserve the original qualities of fruits and vegetables. The brochure will help gardeners and housewives cope with this matter most successfully.
