Embodiment 1

[0022] Fresh lychees are peeled and pitted, beaten, added with 1g / kg of pectinase at 45°C for 1.5h, inactivated at 80°C for 2min, filtered through 200-mesh gauze to obtain litchi juice. Determination of soluble solids content in litchi juice. Add sodium caseinate accounting for 1% by mass of the total soluble solids in the lychee juice to the lychee juice and mix evenly. -0.1KPa, use a rotary evaporator at 50°C to vacuum concentrate the lychee juice until the soluble solid content in the lychee juice is 10%, heat the lychee juice to 50°C in a water bath, at an inlet temperature of 180°C, an inflow volume of 160mL / h, and a hot air flow rate of 24m 3 Spray-dried under the condition of / h, after cooling, litchi instant powder was obtained, and the yield was 45.65%.

Embodiment 2

[0024] Fresh lychees are peeled and pitted, beaten, added with 2g / kg of pectinase at 45°C for 1.5h, inactivated at 80°C for 2min, filtered through 200-mesh gauze to obtain litchi juice. Determination of soluble solids content in litchi juice. Add sodium caseinate accounting for 3% by mass of the total soluble solids in the lychee juice to the lychee juice and mix evenly. -0.1KPa, use a rotary evaporator at 50°C to vacuum concentrate the lychee juice to a soluble solid content of 25%, heat the lychee juice to 50°C in a water bath, at an inlet temperature of 170°C, an inflow volume of 240mL / h, and a hot air flow rate of 17m 3 It was spray-dried under the condition of / h, and after cooling, litchi instant powder was obtained with a yield of 51.08%.

Embodiment 3

[0026] Fresh lychees are peeled and pitted, beaten, added with 3g / kg of pectinase at 45°C for 1.5h, inactivated at 80°C for 2min, filtered through 200-mesh gauze to obtain litchi juice. Determination of soluble solids content in litchi juice. Add sodium caseinate accounting for 5% by mass of the total soluble solids in the lychee juice to the lychee juice and mix evenly. -0.1KPa, use a rotary evaporator at 50°C to concentrate in vacuum until the soluble solids content in the litchi juice is 50%, heat the litchi juice to 50°C in a water bath, at an inlet temperature of 180°C, a liquid intake of 200mL / h, and a hot air flow rate of 21m 3 It was spray-dried under the condition of / h, and after cooling, litchi instant powder was obtained with a yield of 53.79%.

[0027] Taking the lychee instant powder that the present invention makes as an example to carry out physicochemical property analysis, further elaborate the beneficial effect process of the present invention as follows: ...

Abstract

The invention discloses instant litchi chinensis powder and a preparation method thereof. The instant litchi chinensis powder is prepared through the following steps of: adding sodium caseinate to litchi chinensis juice, blending, concentrating under vacuum condition until the content of soluble solid reaches 10-50%, and spray drying. In the preparation method, the sodium caseinate is taken as drying adjuvant additive for spray drying, the dosage of the sodium caseinate is only 4% of maltodextrin when the maltodextrin is used as drying adjuvant additive, and the yield is higher. The instant litchi chinensis powder prepared through the method is directly drinkable or can be prepared to be granules, powder preparation, tablets, capsules or drinks together with one or a plurality of medically acceptable carriers.

Description

technical field [0001] The invention relates to a litchi instant powder, and also relates to a preparation method of the instant powder. Background technique [0002] Litchi is a tropical and subtropical characteristic fruit with unique fruit aroma, rich nutrition and remarkable nourishing effect. Litchi pulp is rich in nutrition, in addition to containing more trace elements, vitamins and phenolic substances, it also has a higher content of carbohydrates. my country is the main producing country of litchi, and its cultivation area and output both rank first in the world. Litchi matures in high-temperature and high-humidity seasons, the production period is concentrated, and it is not resistant to storage. Therefore, various products such as dried fruit, fruit powder, and fruit wine are of great significance for adjusting the supply and demand balance of litchi production period and developing my country's litchi industry and profitable agriculture. [0003] In addition, l...
