Sugarcane is a perennial herb of arborescent family and is widely planted in tropical regions in south such as Guangxi and Guangdong in China. Sugarcane has high sugar content and is rich in various trace elements which are easily lacked by human bodies, wherein the content of iron element is at the top of fruits, so the sugarcane is often called as 'enriching fruits' and 'iron stem crops'. Along with the improvement of living standard and the pursuit of healthy life, the demand of people for natural beverage is increasing. The sugarcane juice contains rich polyphenol and flavonoid substances and has better oxidation resistance, inflammation resistance and mutation resistance, but the sugarcane juice in China is mainly used for producing white granulated sugar at present, and the sugarcane sugar industry has the problem of single product, so that the development of the sugar industry is limited.
Mulberry, also known as Mulberry, Mulberry fruit, Black Mulberry, etc., is the fruit cluster of the mulberry of Morus genus of Urticales order. The mulberry not only contains essential amino acids and various nutrient substances required by human body, but also has the effects of resisting oxidation, preventing cardiovascular and cerebrovascular diseases, inhibiting the growth of cancer cells, regulating immunity and the like, so that the mulberry is listed as one of the agricultural products of 'homology of medicine and food' which are food and medicine by the ministry of health of China. However, the mulberry has short picking period and high moisture, belongs to berry class, is not pressure-resistant, is easy to rot and deteriorate, is difficult to store and transport, and can cause great resource waste and environmental pollution once deteriorating.
With the development of agriculture, the deep processing of agricultural products is particularly important, and the application of the sugarcane and the mulberry to the fruit and vegetable beverage can solve the problem of short storage and preservation time, improve the additional value of the sugarcane and the mulberry and improve the economic benefit. However, the concentration of cane sugar in the cane juice is generally about 16%, the taste is too sweet and greasy, the sugar content is too high, the body health of a drinker is not facilitated, the cane sugar is diluted by adding water until the content of cane sugar is about 10%, the sweetness is proper, the faint scent flavor of the cane sugar can be lost, the taste is weak and single, and the cane sugar cannot adapt to the taste of the public. The mulberry juice contains abundant amino acids and polyphenols, is slightly sweet and sour in taste, slightly bitter and astringent in taste and poor in drinking taste, and restricts the industrialization of sugarcane and mulberry for making fruit and vegetable beverages. In the prior art, sugarcane juice is generally fermented to prepare fruit wine or fruit vinegar for blending, so that the functionality is improved, the taste is improved, but the fruit wine still belongs to wine, the taste of the fruit vinegar is sour, the requirements of all consumers cannot be met, and the large-scale production of the fruit wine is restricted, so that the research and development of the mulberry-sugarcane compound beverage which is wide in audience and unique in taste has important significance.

Test examples
Firstly, the method comprises the following steps: experimental examples 1-5 influence of the ratio of Mulberry juice and sugarcane juice on mouthfeel
Test example 1
The sugarcane juice and the mulberry juice are obtained by diluting sugarcane concentrated juice and mulberry concentrated juice; the sugarcane concentrated juice and the mulberry concentrated juice are purchased, wherein 4 times of water is added into the sugarcane concentrated juice for dilution; and (4) adding 15 times of water to dilute the mulberry concentrated juice. Then, the mulberry juice and the sugarcane juice are mixed according to the proportion of 20% to 50%.
The contents of the mulberry juice and the sugarcane juice were different in test examples 2 to 5 compared to test example 1. The compound beverages obtained in test examples 1 to 5 were subjected to sensory evaluation, and the results are shown in Table 4 below.
TABLE 4 analysis of the results
Figure BDA0002560882090000091
As can be seen from Table 4, when the ratio of mulberry juice to sugarcane juice was 30%: 40%, the sensory evaluation score was the highest and was 90 points, which is probably because the sugarcane juice had a sweeter mouthfeel, and when the sugar juice was too strong, the sugarcane taste was too strong, which resulted in a sweet and greasy taste of the beverage, and a little bitter taste at the tip of the tongue. The mulberry juice is sour in taste, the mulberry is heavy in taste when the mulberry juice is excessive, the flavor is poor, the color of the compound beverage is dark black, and the mulberry juice is not easily accepted by consumers in sense. Therefore, the optimal ratio of the mulberry juice to the sugarcane juice is determined to be 3:4, namely 30% of the mulberry juice and 40% of the sugarcane juice.
II, secondly: test example 6-10 influence of jasmine tea soup on mouthfeel
Test example 6 the formulation and preparation method of example 5 were used, and in test examples 7-10, the mass fraction of jasmine tea soup was different, and the other formulations and steps were the same. The compound beverages obtained in test examples 6 to 10 were subjected to sensory evaluation, and the results are shown in Table 5 below.
TABLE 5 analysis of the results
Beverage product Test example 6 Test example 7 Test example 8 Test example 9 Test example 10
Adding amount of jasmine tea soup 15% 20% 22% 25% 29%
Sensory Scoring (score) 86 93 95 98 94
As can be seen from table 5, when the amount of the jasmine tea is 15% to 29%, the sensory score of the jasmine tea tends to increase and decrease, which is probably because the jasmine tea soup can provide fresh aroma to the beverage and adjust the flavor of the mulberry-sugarcane compound beverage, but the too thick jasmine tea soup increases the astringent taste of the beverage, and the too little jasmine tea soup increases the sweet and greasy feeling of the compound beverage. When the addition amount of the jasmine flower tea soup is 25%, the mulberry-sugarcane compound beverage is appropriate in fragrance, moderate in taste and high in sensory evaluation value, so that the optimal addition amount of the jasmine flower tea soup is 25%.
Thirdly, the method comprises the following steps: test examples 11-13 Effect of different drawing solutions on the Properties of sugarcane concentrated juice
Experimental example 11 has the same formula and preparation method as those of the experimental example 3, and compared with the experimental example 11, the pumping agent in the experimental example 12 is NaCl; in test example 13, the drawing agent was sodium gluconate, and the other examples were the same.
As can be seen from FIGS. 1 and 2, three drawing solutionsThe change of the water flux is firstly quickly reduced and then gradually reduced and finally tends to be flat along with the time extension, wherein CaCl2The fastest change of water flux indicates that when the drawing liquid is CaCl2In the process, the speed of the moisture of the clear sugarcane juice in the raw material tank passing through the liquid drawing side is fastest, and the concentration time is shortest; as can be seen from FIG. 2, the soluble solids of the sugarcane juice concentrate all rapidly concentrated over time to reach a maximum value and then tend to be stable, and in the same time, when the extract is CaCl2When the sugar cane juice concentrate is used, the content of soluble solid solution is the largest. Test results show that CaCl is adopted within 30min2For the drawing liquid, the water flux of the sugarcane concentrated juice is the largest, the soluble solid solution reaches 58.3 degrees Bx, and the soluble solid solutions of the NaCl drawing liquid and the sodium gluconate drawing liquid are only 44.5 degrees Bx and 32 degrees Bx respectively. Thus using CaCl2The method is the optimal drawing liquid in the three drawing liquids, has higher osmotic pressure difference, can obtain higher water flux and soluble solid solution, and has the best concentration effect on the concentrated sugarcane juice.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
