Problems solved by technology

Although the pre-cooking process has the above-mentioned functions, it also has the following defects: 1. The raw material will be soft and rotten if the raw material is pre-cooked for a long time in such a high-temperature environment, and the eater cannot feel that the brittleness of the raw material affects the eating taste
2. Pre-cooking at high temperature for a long time will cause the loss of nutrients in the raw materials
3. If the pre-cooking process is short, the ingredients cannot penetrate into the raw materials quickly, and the produced cans cannot be eaten immediately. Usually, it needs to be placed for a period of time before the ingredients such as sugar liquid and acid liquid can penetrate into the raw materials. Penetration into the raw material will increase the pre-cooking time, reducing the production efficiency of canned food

Embodiment 1

[0028] 1. Raw material fruit pretreatment: purchase moderately ripe peaches, peel and pit them and process them into peach petals. Quick-frozen peach petals can also be used. Selection: First, select unqualified fruit petals (with foreign impurities, core, peel, red meat, black heart, pests, etc.) and repair them. Diced: Fresh fruit or quick-frozen peach petals are softened to moderate hardness. After being washed by a fruit washing machine, they are cut into cubes with a dicing machine. Adjust the cutter size of the dicing machine according to product specifications, and evenly feed clean peach petals into cubes. Sorting: The diced fruit that has been cut is screened by a screening machine and magnetically separated. After the water is screened with water control, impurities and unqualified diced fruit (big diced, red meat, black diced, Diseases and insect pests, etc.), after magnetic separation, qualified diced fruit enters the next process, and after accurate weighing, it ...

Embodiment 3

[0060] 1. Raw material fruit pretreatment: purchase moderately ripe peaches, peel and pit them and process them into peach petals. Quick-frozen peach petals can also be used. Selection: First, select unqualified fruit petals (with foreign impurities, core, peel, red meat, black heart, pests, etc.) and repair them. Beating: Beat the selected fruit petals into a pulp for later use.

[0061] 2. Mixed ingredients:

[0062] 1) Dissolving sugar: dissolving white sugar and water in an appropriate ratio, and pouring the dissolved sugar solution into the mixing ingredients pot through a filter.

[0063] 2) Acid dissolving: Dissolve citric acid and water in an appropriate proportion, stir and dissolve thoroughly, then add to the mixing ingredients pot.

[0064] 3) Dissolving other food additives: according to the needs of different products, use antioxidants, etc.

[0065] According to the ingredient list, put the materials (fruit pulp, sugar solution, citric acid solution, etc.) in...

Abstract

The invention discloses a soft-packed can of fruit jam and its processing technology. The technology includes the following steps: 1) raw material pretreatment; 2) mixing ingredients; 3) vacuum cooking: sucking the raw materials and ingredients into a vacuum concentration tank and starting to stir and heat. to 60-70℃, then evacuate the vacuum concentration tank and keep the temperature at 60-70℃ for heating; 4) sterilization and filling; 5) cooling. The processing technology of the fruit jam soft packaging canning of the present invention uses vacuum cooking to replace the traditional pre-cooking process, so that the ingredients can quickly penetrate into the raw material tissue, and the food can be eaten immediately without placing it, so that the eater can feel the sweet and sour taste. Compared with the traditional process, the heating temperature of the raw materials is greatly reduced and the heating time is shortened, so that the raw materials will not be affected by the loss of nutrients in the raw materials and the taste of the raw materials due to excessive heating temperature or long heating time.

Description

[0001] technical field [0002] The invention relates to the field of food, in particular to a processing technology for canned fruits, vegetables, grains and the like and canned food processed by the technology. [0003] Background technique [0004] The key step in the existing canned food preparation process is the pre-cooking process. The pre-cooking process is generally to heat the raw materials (fruits, vegetables, grains, etc.) Soften raw materials, fix the color of raw materials and inactivate the activity of enzymes and other functions. Although the pre-cooking process has the above-mentioned functions, there are also the following defects: 1. The raw material will be soft and rotten if the raw material is pre-cooked for a long time in such a high-temperature environment, and the eater cannot feel that the brittleness of the raw material affects the eating taste. 2. Pre-cooking at high temperature for a long time will cause the loss of nutrients in the raw materia...
