In recent years, iceberg has begun to be commercially grown in China as an emerging health food material.
The iced vegetable is native to arid regions such as south Africa nanometer desert and the like, has strong drought resistance and salt tolerance, can grow on the coast, saline-alkali soil or under the condition of being irrigated by seawater, belongs to typical salt-secreting plants, and the liquid of the bubble-shaped cells contains natural plant salt. The water content in the iced vegetable can reach 95 percent, the water content can reach 97 percent under the condition of saline-alkali soil or seawater irrigation, and the iced vegetable is very suitable for juicing processing. Meanwhile, the natural plant salt contains a large amount of natural plant salts such as potassium, sodium, calcium, magnesium and the like, belongs to low-sodium salt, effectively supplements electrolytes for human bodies, and is more beneficial to the health of the cardiovascular and cerebrovascular systems of the human bodies. Through research, in order to adapt to survival under the condition of saline-alkali stress, many nutritional and active ingredients in the iced vegetable are obviously increased, such as superoxide dismutase (SOD), Catalase (CAT), Peroxidase (POD), total flavonoids, chlorophyll, soluble solids, sodium, calcium, magnesium ions and the like, so that the iced vegetable growing under the condition of saline-alkali stress has higher antioxidant capacity and physiological activity compared with the iced vegetable.
The sports functional beverage can rapidly supplement water, electrolyte and energy to the body during sports, maintain and promote the balance of body fluid or rapidly recover, and delay fatigue, thereby adjusting the body fluid to a balanced state. However, the currently published literature relates to the preparation method of sports functional beverages by adding sodium and potassium salts to provide electrolytes, such as the vitamin sports functional beverage provided by chinese patent document CN105942534A (application No. 201610505494.8) and the preparation method thereof in the form of adding edible well salts, the sports functional beverage provided by chinese patent document CN103535831A (application No. 201310500894.6) in the form of adding sodium chloride and potassium chloride, and the like. The product sold in the market at present has single functional component and does not contain plant nutrient components such as natural chlorophyll, amino acid, polyphenol, flavonoid and other soluble solids.

(8) and (3) homogenizing the stable ice vegetable juice prepared in the step (7) in a dispersion emulsifying machine under the pressure of 10MPa for 5min, filling the homogenized ice vegetable juice into a high-temperature-resistant glass bottle, sealing the glass bottle, placing the glass bottle into a sterilization pot for sterilization treatment at the sterilization temperature of 85 ℃ for 6min, taking out the glass bottle, and rapidly cooling the glass bottle to the normal temperature by flowing water to obtain the ice vegetable juice.
Test example 1
The main nutritional indexes of the iced vegetable juice prepared in example 1 and the iced vegetable juice prepared in comparative example 1 are respectively detected by the detection methods described in table 1, and the detection results are shown in table 1.
TABLE 1
Figure BDA0001389539670000071
As can be seen from Table 1, the content of sodium ions in example 1 is significantly higher than that in the comparative example, and the ratio of sodium ions to potassium ions is closer to that in human blood, and is consistent with that in human sweat, so that the sodium ions and potassium ions lost by human body can be supplemented in time in proportion. In contrast to the fact that the content of potassium ions in the comparative example is significantly higher than that of sodium ions in human blood and sweat discharged, which is significantly higher than that of potassium ions, the balance of sodium and potassium ions in human body is disturbed, and the electrolyte is not balanced, thereby affecting the absorption of water. Meanwhile, the nutrient contents such as soluble solid, vitamin C, flavonoid compounds, chlorophyll and the like in the iced vegetable juice beverage obtained in the example 1 are also obviously higher than those in the comparative example 1, which shows that the iced vegetable grown in the saline-alkali soil under the technical condition is more suitable for processing the sports functional beverage.
Test example 2
The iced vegetable juices prepared in example 1 and comparative example 2 were respectively tested for relevant indexes by the testing methods described in table 2, and the testing results are shown in table 2.
TABLE 2
Figure BDA0001389539670000072
Figure BDA0001389539670000081
As can be seen from Table 2, after the egg white powder adsorbs the suspended matters, the suspended matters are passivated and settled in a heating mode, so that the ice vegetable juice becomes transparent and glossy, no precipitate is generated after long-term storage, and the light transmittance is obviously improved. Meanwhile, the heating condition can passivate the activity of excessive cellulase, protease and pectinase in the compound enzyme agent, so that the compound enzyme agent does not react with concentrated juice any more to generate turbidity and precipitates in the subsequent processing process, thereby improving the sensory quality of the sports function ice vegetable juice.
