Embodiment 1

[0019] Embodiment 1: The low-sugar preserved strawberry fruit is obtained according to the following preparation method: the first step, putting fresh strawberries into boiling water for blanching; the second step, putting the fresh strawberries blanched in the first step into sugar Carry out vacuum osmosis and normal pressure immersion in the liquid in sequence to obtain sugar immersion strawberries, wherein the vacuum degree of vacuum osmosis is 0.04MPa to 0.08MPa, the temperature of the sugar solution is 50°C to 70°C, and the normal pressure immersion sugar The time is 5 hours to 10 hours, and the sugar solution is obtained by the following method: the parts by weight are 30 parts to 50 parts of fructose syrup, the parts by weight are 0.5 parts to 2 parts of isomaltooligosaccharide and the parts by weight are 0.1 to 0.4 parts of L-cysteine ​​are mixed to obtain a sugar solution; the third step is to remove the sugar-soaked strawberries from the sugar solution, drain the su...

Embodiment 2

[0020] Embodiment 2: The low-sugar preserved strawberry fruit is obtained according to the following preparation method: the first step is to put fresh strawberries into boiling water for blanching; in the second step, put the fresh strawberries blanched in the first step into sugar Carry out vacuum osmosis and normal pressure sugar immersion in the liquid sequentially to obtain sugar immersion strawberries, wherein, the vacuum degree of vacuum osmosis is 0.04MPa or 0.08MPa, the temperature of sugar solution is 50°C or 70°C, and the normal pressure immersion sugar The time is 5 hours or 10 hours, and the sugar solution is obtained by the following method: the parts by weight are 30 parts or 50 parts of fructose syrup, the parts by weight are 0.5 part or 2 parts of isomaltooligosaccharide and the parts by weight are 0.1 or 0.4 parts of L-cysteine ​​are mixed to obtain sugar solution; the third step is to remove the sugar-soaked strawberries from the sugar solution, drain the s...

Embodiment 3

[0021] Embodiment 3: The low-sugar preserved strawberry fruit is obtained according to the following preparation method: the first step, putting fresh strawberries into boiling water for blanching; the second step, putting the fresh strawberries blanched in the first step into sugar Carry out vacuum osmosis and normal pressure sugar immersion in sequence in the liquid to obtain sugar soaked strawberries, wherein the vacuum degree of vacuum osmosis is 0.06MPa to 0.08MPa, the temperature of sugar solution is 58°C to 63°C, and the normal pressure sugar immersion The time is 5 hours to 7 hours, and the sugar solution is obtained by the following method: the parts by weight are 30 parts by weight of 42 parts of fructose syrup, the parts by weight of isomaltooligosaccharide and the parts by weight of 0.1 part of L -The sugar solution is obtained after the cysteine ​​is mixed; the third step is to remove the sugar-soaked strawberries from the sugar solution, drain the sugar solution...

Abstract

The invention relates to the technical field of preserved fruits and preparation methods thereof and provides low-sugar strawberry preserved fruit and a preparation method thereof. The low-sugar strawberry preserved fruit is prepared through steps as follows: step one, performing blanching; step two, performing vacuum sugar infiltration and normal-pressure sugar soaking; step three, draining sugar liquor and processing with carrageenan; step four, drying the sugar-soaked strawberries after processing with carrageenan to obtain the preserved fruit; step five, placing the preserved fruit in a closed container and softening the preserved fruit to obtain the low-sugar strawberry preserved fruit. The sugar content of the low-sugar strawberry preserved fruit is 30%-40%, and besides, the low-sugar strawberry preserved fruit has the characteristics of good appearance plumpness, strong fruit flavor, bright color, high nutrient value and good chewing toughness, and meets eating requirements of customers for taste, nutrient value and safety of food at present.

Description

technical field [0001] The invention relates to the technical field of preserved fruit and a preparation method thereof, and relates to a low-sugar strawberry preserved fruit and a preparation method thereof. Background technique [0002] Strawberry belongs to berry category. Its pulp is juicy and tender, moderately sweet and sour, with attractive color and pleasant aroma that ordinary fruits do not have. It is a rare fruit with excellent color, aroma and taste. Strawberries are rich in nutrients and contain fructose, sucrose, citric acid, malic acid, salicylic acid, amino acids, calcium, phosphorus, iron and other minerals. Strawberry is not only nutritious, but also has high medical and health care effects. It has the effects of moistening lungs and promoting body fluid, invigorating spleen and stomach, nourishing blood and Qi, cooling blood, and detoxifying. However, due to the extremely high water content of strawberry fruit, it is extremely vulnerable to mechanical dam...
