preparation example Construction

[0026] Such as figure 1 Shown, the preparation method of the kiwi compound jam of the embodiment of the present invention comprises the following steps:

[0027] S101: Take appropriate amount of kiwi fruit, apple and carrot respectively, wash, blanch (apple and carrot are blanched in hot water at 90°C to 95°C for 5 minutes each), and peeled (especially kiwi fruit with a mass fraction of 18%-25%) caustic soda solution, rinse with running water);

[0028] S102: Cut kiwi fruit, blanched apples and carrots into small pieces respectively, and promptly use 0.5% L-cysteine, 0.3% Vc, 0.2% oxalic acid, and 0.5% NaCl for color protection and anti-browning treatment respectively;

[0029] S103: Take out the pulp after the color protection treatment in proportion, put it in a beater to make a slurry, first add an appropriate amount of water-diluted glucose oxidase 5ppm to 100ml of evenly beaten compound jam, and then add appropriate chlorination Calcium, citric acid (pH value adjusted t...

Embodiment 1

[0033]A kind of kiwi fruit compound jam and its anti-browning method, its preparation method after process optimization:

[0034] (1) For material selection, choose nine-ripe kiwifruit, choose fresh apples with appropriate maturity and high quality, and choose fresh orange-yellow carrots with dense texture and thin central columns.

[0035] (2) Cleaning Wash the raw materials with clean water to remove dirt and other impurities attached to the surface.

[0036] (3) Blanch and blanch in hot water at 90°C to 95°C (5 minutes each for apples and carrots) to inactivate enzymes and soften tissues, and then enter the beating process after completion.

[0037] (4) Peeling and color protection Peel the kiwi fruit with a caustic soda solution with a mass fraction of 18%-25%, rinse it with running water, cut the kiwi fruit, blanched apples and carrots into small pieces respectively, and use 0.5% caustic soda solution in time. L-cysteine, 0.3% Vc, 0.2% oxalic acid, and 0.5% NaCl are resp...

Abstract

The present invention discloses a compound kiwi fruit jam and a preparation method thereof, which uses a combined technology of bio-enzymes and chemical methods. The compound kiwi fruit jam includes kiwi fruits, apples and carrots according to a mass ratio of 1.0 : 0.5 : 0.5, and an addition amount of 10% of white granulated sugar, 1% of citric acid, 0.2% of calcium chloride, 0.3% of D-sodium erythorbate, 0.5% of low-methoxy pectin, and 0.1% of sodium carboxymethyl cellulose. The preparation method comprises the following steps: choosing materials, cleaning, blanching, peeling, protecting color, beating, and concentrating, and effectively suppressing the browning problem of the compound kiwi fruit jam. The preparation method ensures the savings of resources and extends the fruit preserving time. The three fruits of kiwi fruits, apples, and carrots can supplement various vitamins, and at the same time the compound kiwi fruit jam is rich in nutrition and has important functions of beautifying features and keeping young, helping digestion, improving intestines, maintaining human body health, and preventing and curing diseases.

Description

technical field [0001] The invention belongs to the technical field of food production, and in particular relates to a kiwi fruit compound jam and a preparation method thereof. Background technique [0002] Kiwi fruit is a kind of fruit that is deeply loved by consumers. Its fruit is tender and juicy, fragrant and delicious, pleasantly sweet and sour, and extremely rich in nutrition. Its vitamin C content is as high as 100-420g / 100mg. Kiwi fruit can be said to be the "king of fruit Vc". According to the test by the Food Research Center of Rutgers University in the United States, kiwi fruit is the most nutritious and comprehensive fruit among various fruits. Therefore, it plays an important role in maintaining human health, preventing and treating diseases. It can help digestion and effectively improve intestinal function. In addition, studies have shown that kiwi fruit also has a certain effect on preventing and reducing the incidence of coronary heart disease, hypertensio...
