Abstract

The invention discloses a preparation method of a vacuum freeze-dried banana product. The preparation method comprises the following steps: 1) removing fruit peels of bananas, and taking out fruit flesh; 2) evenly laying the banana fruit flesh on an aluminum plate with the thickness of 3 to 5 cm, the steam temperature of 121 to 125 DEG C, the time of 120 to 150 seconds and the material central temperature of not less than 75 DEG C; 3) cooling the fruit flesh to the room temperature; 4) preparing a mixed solution, wherein according to the mass ratio, the solution contains 0.2 to 0.5% of iso-VC sodium, 0.1 to 0.3% of tea polyphenols, 0.6 to 1.0% of glucose, and 1.0 to 1.5% of dextrin; 5) soaking the fruit flesh in the mixed solution for 10 to 15 s; and 6) carrying out vacuum freeze drying, wherein the technical parameters comprise the plate laying thickness is 2 to 3 cm, the vacuum degree is 80 to 100 Pa, the cryo-temperature is -30 to -40 DEG C, the sublimation temperature is 40 to 50 DEG C, the time is 8 to 10 hours, the vacuum degree of the vacuum drying process is 60 to 80 Pa, the drying temperature is 50 to 60 DEG C, and the time is 6 to 8 hours. The product is not browned in the production process, and is not browned within 30 minutes after be brewed with a soymilk product.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a method for preparing vacuum freeze-dried banana products. Background technique [0002] Banana is a high-calorie fruit. According to analysis, the calorific value per 100 grams of pulp reaches 91 kcal. Bananas are also used as a staple food in some tropical regions. The nutritional value of banana pulp is quite high. Every 100 grams of pulp contains 20 grams of carbohydrates, 1.2 grams of protein, and 0.6 grams of fat; in addition, it also contains a variety of trace elements and vitamins. Among them, vitamin A can promote growth and enhance resistance to diseases, which is necessary to maintain normal fertility and vision; thiamine can resist beriberi, promote appetite, help digestion, and protect the nervous system; riboflavin can promote normal growth and development of the human body. development. In addition to stabilizing serotonin and melatonin, bananas ...
