Problems solved by technology

[0003] But the shelf life of jam is usually shorter, that is, the shelf life is shorter, and it is easy to deteriorate. How to improve the shelf life of jam by changing the formula or changing the production process or tools is the problem to be solved by this utility
[0004] The length of the jam shelf life is directly related to the oxygen content in the jam. In the prior art, preservatives are generally added to the jam to prevent the growth of bacteria and fungi, thereby improving the shelf life of the jam. However, the preservatives have certain effects on the body of the eater. Therefore, it is necessary to reduce the oxygen content in the jam as much as possible during the production process, and improve the shelf life of the product while ensuring food safety

Embodiment 1

[0036] A kind of jam with a long shelf life, its raw materials include 1 kg of strawberry, 0.1 kg of white granulated sugar, 0.3 kg of syrup, 0.2 kg of thickener, 0.02 kg of citric acid, appropriate amount of distilled water and nitrogen, and 1 kg of strawberry Dice the strawberries and put them into the tank, add distilled water, white sugar, syrup, thickener and citric acid in sequence for mixing, and inject nitrogen into the raw materials during the mixing process, the injection of nitrogen will replace the tank Body 1 and the oxygen stored inside the raw materials, reduce the oxygen content in the jam, and avoid the growth of bacteria and fungi.

Embodiment 2

[0038] A kind of jam with a long shelf life, its raw materials include 1 kg of apples, 0.15 kg of white granulated sugar, 0.4 kg of syrup, 0.3 kg of thickener, 0.01 kg of citric acid, appropriate amount of distilled water and nitrogen, and 1 kg of strawberry Dice the apples and put them into the tank, add distilled water, white sugar, syrup, thickener and citric acid in sequence for mixing, and inject nitrogen into the raw materials during the mixing process, because the density of apples is different from that of strawberries. Different, and the addition amount of various additives is different, so there is a certain difference in the density of the jam, so there is a certain difference in the nitrogen content stored in the jam.

[0039] The content of nitrogen will directly affect the shelf life of jam, and the mass ratio of white sugar and syrup in jam will directly affect the sweetness of jam. The higher the ratio of white sugar and syrup, the sweeter the jam, while the rat...

Abstract

The invention discloses jam with a long shelf life and production equipment of the jam, and relates to the field of food. The jam with the long shelf life comprises the raw materials of fruits, white granulated sugar, syrup, a thickening agent, citric acid and distilled water. The jam with the long shelf life comprises the following raw materials in percentage by mass: 50% to 65% of the fruits, 5% to 10% of the white granulated sugar, 15% to 20% of the syrup, 10% to 20% of the thickening agent, 0.2% to 1% of the citric acid and a proper amount of the distilled water. The thickening agent comprises pectin, gellan gum and sodium alginate, the ratio of all the components is 1: 1: 1, and the fruits need to be peeled, denucleated and diced. According to the jam with the long shelf life and the production equipment of the jam, by injecting nitrogen into a tank body and emptying oxygen stored in the tank body and the raw materials, air can be effectively isolated, the oxygen content in the jam is reduced, bacteria and fungi are prevented from breeding, and the shelf life of the jam is prolonged.

Description

technical field [0001] The invention relates to the field of food, in particular to jam. Background technique [0002] Jam, sweet and sour, is a convenient food for Western food, picnics, and home travel. It is also one of the filling materials for cakes, bread, candy, ice cream and other foods. Jam contains natural fruit acids, which can promote the secretion of digestive juices. The effect of digestion, jam can also increase pigment, which has auxiliary effect on iron deficiency anemia. [0003] But the shelf life of jam is usually shorter, that is, the shelf life is shorter, and it is easy to deteriorate. How to improve the shelf life of jam by changing the formula or changing the production process or tools is a practical problem to be solved. [0004] The length of the jam shelf life is directly related to the oxygen content in the jam. In the prior art, preservatives are generally added to the jam to prevent the growth of bacteria and fungi, thereby improving the shel...
