preparation example Construction

[0032] like figure 1 Shown, the preparation method of the reduced-sugar fruit juice provided by the invention comprises the following steps:

[0033] Step S1, thawing the frozen squeezed juice cubes.

[0034] The juice is made by freshly squeezed natural fruit without adding any preservatives or ingredients. After being squeezed into juice, it is stored under freezing conditions below -18°C. The transportation process is also carried out through the cold chain. controlled within 2°C. Juice types include but not limited to grape juice, mango juice, orange juice, pear juice. The fruit juice after arrival needs to be thawed before membrane treatment.

[0035] Generally, the natural thawing method can be used, and the unopened sealed fruit juice is placed in a cool place to thaw at room temperature, but the room temperature should not exceed 30°C, and placed for 3-8 hours until the ice cubes are completely melted.

[0036] When thawing naturally, the melting of ice crystals in...

Embodiment 1

[0052] Thaw the grape juice, and then use a 200-mesh filter bag to filter the juice. The filtration process is carried out at room temperature. After filtration, no precipitated fruit particles and other physical foreign matter remain; the filtered grape juice is ultra-filtered to remove solids at room temperature. The pore size of the ultrafiltration membrane core is 60nm, the control pressure is 1.2MPa during the operation, and the operation time is 3.5h. When the temperature of the material rises to more than 25 degrees Celsius due to the pressure increase, the cooling circulating water is started to control the grape juice material below 25 degrees Celsius.

[0053] The grape juice after ultrafiltration and solid removal was sent as a sample for sugar detection.

[0054] Take 40L of grape juice after ultrafiltration and solid removal treatment and pour it into the circulation tank of the nanofiltration equipment. The nanofiltration equipment is equipped with a membrane core...

Embodiment 2

[0058] Take the apple juice to thaw, and then use a 250-mesh filter bag to filter the juice. The filtration process is carried out at room temperature. After filtration, no precipitated fruit particles and other physical foreign matter remain; the filtered apple juice is ultra-filtered to remove solids at room temperature. The pore size of the ultrafiltration membrane core is 70nm, the control pressure is 1.0MPa during the operation, and the operation time is 3 hours. When the temperature of the material rises to more than 25 degrees Celsius due to the pressure increase, the cooling circulating water is started to control the apple juice material below 25 degrees Celsius.

[0059] The apple juice after ultrafiltration and solid removal was sent as a sample for sugar detection.

[0060] Take 40L of apple juice after ultrafiltration and solid removal treatment and pour it into the circulation tank of the nanofiltration equipment. The nanofiltration equipment is equipped with a me...

Abstract

The invention is applicable to the technical field of food processing, and provides sugar-reduced fruit juice and a preparation method thereof, and the preparation method comprises the following steps: unfreezing frozen squeezed fruit juice ice blocks; performing primary filtration treatment on the unfrozen fruit juice; carrying out ultrafiltration solid removal treatment on the filtered fruit juice; carrying out nanofiltration sugar reduction treatment on the fruit juice subjected to ultrafiltration solid removal; and sterilizing and packaging the fruit juice subjected to nanofiltration sugar reduction treatment. The natural fruit juice is used as a main raw material, sugar is reduced through a physical membrane filtration method, part of sugar such as glucose, fructose and cane sugar in the processed fruit juice is removed, the calorie value of the natural fruit juice is reduced, and the natural beverage conforming to the beverage development trend is prepared and is beneficial to health of consumers.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a sugar-reduced fruit juice and a preparation method thereof. Background technique [0002] Fruit juice is a juice product obtained by physical methods such as pressing, centrifuging, and extraction with fruits as raw materials, and can be processed into various fruit juice drinks. Juice retains most of the nutrients in fruits, such as vitamins, minerals, sugar and pectin in dietary fiber. Drinking fruit juice often can help digestion, moisten the intestines, and supplement the lack of nutrients in the diet. According to the latest healthy diet standard advocated by the World Health Organization (WHO): "Eat at least 400 grams (5 servings) of fruits and vegetables every day." It is difficult to meet this standard by supplementing vegetables and fruits with three meals a day alone. If fruits and vegetables are taken in three meals a day, combined with fruit an...
