Sugar is the main additional raw material in fruit canning. It regulates the taste of canned fruits and vegetables; in certain concentrations, sugar is used as a preservative (jams, marmalades, jellies). It is indirectly involved in canning during alcohol fermentation. It is characterized by high calorie content.
For canning with sugar, mainly refined granulated sugar is used. Other types of sugar are less suitable. The sugar concentration in syrup or juice is most easily measured by a saccharimeter: 1 kg of dissolved sugar is 0.62 liters.
Artificial sweet substances in canning sometimes replace sugar when it is undesirable (in canned products for diabetics) or excessive (in syrups for canned vegetables). Artificial sweet substances do not add flavor to canned foods and are unsuitable for those suffering from diseases of the digestive tract. The sweetness is much higher than sugar. The following artificial sweet substances are on sale (the number in parentheses indicates how many times sweeter it is than sugar): saccharin T 110 (110X), saccharin T 500 (500X), spolarin (40X), dukaryl (35X).
Acids. With their help, the taste qualities of canned fruits and vegetables are regulated and a certain degree of active acidity is achieved, which makes possible sterilization at temperatures up to 100 ° C and the formation of a gel from pectin substances. When canning vegetables and fruits, some acids perform a direct preservative function.
Vinegar is a product of fermentation of dilute alcohol by acetic acid bacteria. It is sold with 8-10% acetic acid (in 8-10% concentration). It is used to make spicy marinades and adjust the taste qualities of brines. It has long been used in canning. But such canned food is characterized by unpleasantly acute acidity, so you should abandon this method of canning.
Citric acid is the most widely used among acids in fruit processing. It tastes more delicate than acetic acid. It has no preservative, but only a bleaching effect. It is used in cases where it is necessary to increase the acidity of canned fruits, and sometimes vegetables. It forms white crystals. "A tablespoon contains about 15 grams of citric acid, a teaspoon contains about 5 g. Tartaric acid is used similarly to citric acid.
Benzoic acid is sometimes used in the canning of vegetables. It is a white shiny powder, poorly soluble in water. It dissolves better in hot water, so when canning (for example, vegetables) it is added to the hot filling.
Sodium benzoate is used similarly to benzoic acid. It is easily soluble in water. The efficiency is about 20% lower than that of benzoic acid. When preparing vinegar fillings, sodium benzoate is first dissolved, and then vinegar is added. Otherwise, sodium benzoate is released from the solution in the form of benzoic acid precipitates. A 5% solution (2 teaspoons of benzoic sodium per 1 liter of water) is used to preserve the surface layer of pastes.
Formic acid diluted with water in a ratio of 1:12 is sometimes used to preserve the surface layer of pastes. Formic acid is added as an 85-90% solution; a 5% solution for preserving the surface layer of pastes is obtained by adding 1 teaspoon of acid to 0.1 liters of water. Sulfur dioxide is a crystalline salt containing up to 50% sulfur oxide, which is released in an acidic environment. It decomposes easily, so it should be stored in tightly sealed flasks. It is sold in powder or tablets (10 pcs each. in the package). Each tablet weighs 10 g and contains 5 g (500 mg) of sulfur oxide.
Of the other substances, pectin should be mentioned. Sometimes its content in fruits is not enough to achieve the desired degree of gelling in the production of marmalades, jams and jellies. In such cases, technical pectin obtained from apple pomace is added. There is a Petosa preparation on sale with a standard LC of 20 ° (LC gelling ability; expressed by a number indicating the ratio of sugar and pectin, at which a 65% sugar solution freezes).
