Test results and analysis
1)Influence of the blanching time to hollow humilis preserved fruits quality
As shown in Figure 2, the different blanching times being handled at 85 DEG C, hollow humilis preserved fruits sensory evaluation scores are minimum when non-blanching, The black dull tarnish of color, sour-sweet salty ratio is uncoordinated, and preserved fruit atrophy is apparent, and most of to be recessed, sugar content is relatively low, because not Blanching is carried out, is unfavorable for oozing sugar.It being gradually increased with the blanching time, hollow humilis preserved fruits sensory evaluation scores and sugar content are also gradually increasing, As 3 min of blanching, hollow humilis preserved fruits sensory evaluation scores reach highest, and hollow humilis preserved fruits appearance is glossy, uniform color, knot of tissue Structure is full, and hollow plum fruity is apparent, and sour-sweet salty ratio is moderate, and sugar content is relatively high, when 4 min of blanching hollow humilis preserved fruits sense organ Scoring declines, and hollow humilis preserved fruits preserved fruit appearance atrophy is apparent, most of to be recessed, since blanching time length causes pericarp by broken Ring makes its quality decline.Therefore, the blanching time is the hollow humilis preserved fruits performance optimals of 3 min.
2)Influence of the blanching temperature to hollow humilis preserved fruits quality
The selection of blanching temperature is vital, should ensure to achieve the effect that inactive enzyme within the shortest time, also to prevent Only the excessively high pulp of temperature is influenced the quality of preserved fruit by well-done.When blanching temperature as shown in Figure 3 is 80 DEG C preserved fruit sensory evaluation scores compared with Low, because blanching temperature is relatively low, hollow plum enzyme is not passivated completely, so the black dull tarnish of preserved fruit color, atrophy is apparent, fruity Taste unobvious, the sensory evaluation scores highest when temperature is 85 DEG C, preserved fruit is glossy and uniform, and hollow plum fruit flavor is apparent, sugar content Higher, when temperature is higher than 85 DEG C, preserved fruit sensory evaluation scores and sugar content are reduced with the raising of blanching temperature, since temperature is excessively high It causes fruit surface to be boiled bad, influences appearance, the color and luster of preserved fruit, cause preserved fruit atrophy serious, and quality is harder, be unfavorable for Edible, sugar content seriously is unfavorable for oozing sugar since the tissue cellularity of the excessively high pulp of temperature destroys, and sugar content is caused to decline.Cause This, blanching temperature is that 85 DEG C of hollow humilis preserved fruits qualities are best.
3)Influence of the drying temperature to the quality of hollow humilis preserved fruits
Drying temperature is affected to hollow humilis preserved fruits quality, and control drying temperature is a critical issue, the excessively high meeting of temperature Cause preserved fruit surface drying shrinkage serious, and caramel reaction can occur for sugar so that the hollow black tarnish of humilis preserved fruits darker in color, and temperature mistake Height can cause sugar loss serious.Drying temperature sensory evaluation scores highest at 55 DEG C as shown in Figure 4, hollow humilis preserved fruits are glossy, empty Heart Lee's fruit flavor is apparent, delicate mouthfeel, when drying temperature is less than 55 DEG C since temperature is relatively low, hollow humilis preserved fruits moisture Higher, tissue morphology is full, and moisture enrichment causes preserved fruit without chewy texture, and mouthfeel is poor, the sense organ when drying temperature is higher than 55 DEG C Scoring declines, since drying temperature is excessively high so that preserved fruit quality is hard, and be faint in color unrelated pool, is unfavorable for eating.With drying The increase of temperature, sugar content gradually increase, the sugar content highest when drying temperature reaches 60 DEG C, when drying temperature is more than 60 DEG C When sugar content reduce, since temperature height makes sugar be lost, and sugar content reduce.Therefore, consider each factor, it is dry Temperature is 60 DEG C of hollow humilis preserved fruits performance optimals.
4)Influence of the drying time to hollow humilis preserved fruits quality
The selection of drying time is to obtain the most important link of high-quality preserved fruit as shown in Figure 5 in 25 h of drying time to contain Sugar amount highest, with the growth of its drying time, sugar content continuously decreases, because being dried for a long time under conditions of sugar is at 60 DEG C It can incur loss, preserved fruit sugar content is caused to continuously decrease, sensory evaluation scores highest when drying time is 35 h, preserved fruit color is bright to be had Gloss, delicate mouthfeel, fruit flavor is apparent, and sensory evaluation scores are relatively low when drying time is less than 35 h, because drying time not enough causes Preserved fruit water content is higher, and hollow humilis preserved fruits mouthfeel is not good enough, hollow plum fruit flavor unobvious, when drying between be higher than 35 h when it is hollow Humilis preserved fruits sensory evaluation scores reduce, tissue morphology atrophy, and shrivelled serious, quality is harder, since drying time is long, hollow humilis preserved fruits Dehydration is serious, and sensory evaluation scores are relatively low.Therefore, drying time is the hollow humilis preserved fruits performance optimals of 35 h.
5)Influence of the drying mode to hollow humilis preserved fruits quality
Microwave drying has the function of sterilization, but can be brought a negative impact to the appearance of product, color and luster and taste, as shown in Figure 6 When carrying out microwave drying, hollow humilis preserved fruits color is black dull, and matt, uneven color is even, hollow plum fragrance unobvious, no chewy texture, Cause its sensory evaluation scores relatively low, but the hollow humilis preserved fruits sugar content through microwave drying treatment is relative to other three kinds of drying means Highest, mainly shorter due to carrying out the microwave drying time, sugar loss is less, and sugar content is high, and convective airflow drying is sharp In the holding of hollow humilis preserved fruits shape, hollow humilis preserved fruits appearance is glossy, and the salty ratio of sweet mouthfeel is moderate, and sugar content is relatively Height, sensory evaluation scores highest, and natural air drying and then climate influence is dried, and drying time longest, hollow plum in the drying process Sugar alcohol is converted into due to anaerobic respiration, and due to the uncontrollable factor of weather, prolonged place can lead to preserved fruit It goes mouldy, so hollow humilis preserved fruits mouthfeel is bad, appearance and color and luster are all without also poor, and sugar content is also than remaining two methods Low, sensory evaluation scores are minimum.Therefore, hollow humilis preserved fruits performance optimal when convective airflow drying.
6)Ooze influence of the sugared mode to hollow humilis preserved fruits quality
The quality that sugar is conducive to improve hollow humilis preserved fruits is oozed, normal pressure oozes the osmotic pressure that sugar utilizes saline solution, and hollow plum is made to generate matter wall Segregation phenomenon achievees the effect that meat is tender and crisp and keeps preserved fruit nutritional ingredient, and ultrasonic wave oozes sugar can be in sugaring liquid using ultrasonic wave The intensity of middle generation cavitation, caused shock wave and jet stream is enough the cell membrane of moment breakdown hollow plum, reaches quickening The effect of infiltration, oscillation ooze the opposite normal pressure of sugar and both ooze for sugar that principle is consistent, and oscillation, which is oozed for the opposite normal pressure of sugar oozes sugar, to be shortened It oozes the sugared time, and it is sugared uniform so that hollow humilis preserved fruits ooze.Three kinds as shown in Figure 7 ooze normal pressure in sugared mode ooze sugar sensory evaluation scores and Sugar content is minimum, and preserved fruit color is partially dark uneven, and mouthfeel is bad, hollow plum fruit flavor unobvious, and salting period is long, and ultrasonic Wave oozes sugared sensory evaluation scores and sugar content highest, and hollow humilis preserved fruits gloss is uniform, and good mouthfeel, hollow plum fruit flavor is apparent, sugaring Time is short, and sugar is oozed in oscillation, and greatly shortening is oozed the sugared time on the basis of normal pressure oozes sugar, and the hollow humilis preserved fruits quality of gained is than normal Pressure oozes sugar more preferably.Therefore, ultrasonic wave oozes hollow humilis preserved fruits performance optimal when sugar.
7)Influence of the citric acid additive amount to hollow humilis preserved fruits quality
Citric acid has the effects that reducing sugariness, improving flavor, color protection.As shown in figure 8, with the increase of citric acid additive amount, The sensory evaluation scores of hollow humilis preserved fruits are gradually reduced after gradually increasing, when citric acid additive amount reaches 1.5 %, hollow humilis preserved fruits mouth Sense is best, at this time sensory evaluation scores highest, and the sour-sweet salty ratio of preserved fruit is moderate, soft texture and full, and gloss is uniform, hollow plum fruit Fragrance is more apparent, and sour-sweet salty ratio is uncoordinated when citric acid additive amount is 0.5 %, and preserved fruit carries a bitter taste, and hollow plum is fragrant Taste unobvious, color and luster is dimer, and preserved fruit mouthfeel is not good enough when additive amount is 1.0 %, and sour-sweet salty ratio is moderate, but uniform color, Only bitter taste is obvious, leads to preserved fruit entirety mouthfeel defect, and when citric acid additive amount is higher than 1.5 %, preserved fruit is again sour Again bitter, sour-sweet salty ratio is uncoordinated.Therefore, consider, citric acid additive amount selects 1.5 %.
8)Influence of the honey additive amount to hollow humilis preserved fruits quality
Honey can give preserved fruit denseer sweet fragrance, can also moreover improve the composition of blood, promote heart and brain and blood vessel etc..Such as Shown in Fig. 9, with the increase of honey additive amount, the sensory evaluation scores of hollow humilis preserved fruits gradually increase, and are then gradually reduced, and work as honey When additive amount is 1.5 %, hollow humilis preserved fruits mouthfeel is best, there is the sweet fragrance of honey and fine and smooth sense, and sour-sweet salty eurythmy is moderate, Hollow plum fruit flavor is obvious, and gloss is relatively uniform, and form is fuller, and when honey additive amount is less than 1.5 %, preserved fruit lacks Honey exquisiteness sense, quality is harder, and mouthfeel is not good enough, and when honey additive amount is higher than 1.5 %, hollow humilis preserved fruits mouthfeel is compared with sweet tea, honey Fine and smooth sense covered the distinctive fruit flavor of hollow plum.Therefore, consider, honey additive amount selects 1.5 %.
9)Influence of the rock sugar additive amount to hollow humilis preserved fruits quality
Rock sugar can increase the brittleness of preserved fruit, cover the tart flavour of hollow plum, there is the effect of tonifying middle-Jiao and Qi and stomach moistening lung.Such as Figure 10 institutes Show, the sour-sweet salty ratio of hollow plum is moderate when rock sugar additive amount is 1.0 %, and soft texture, hollow plum fruit flavor is apparent, and color and luster is equal Even, form is uniformly full.When rock sugar additive amount is 0.5 %, taste is partially light, and color and luster is dim, and sour-sweet salty ratio is uncoordinated, tissue Form has certain plumpness.Preserved fruit mouthfeel is sourer when rock sugar additive amount is more than 1.0%, and quality is harder, and rock sugar additive amount is higher than Preserved fruit mouthfeel is compared with sweet tea when 1.0 %, and when aftertaste has a little bitter and sour-sweet salty out of proportion.Therefore, consider, rock sugar additive amount Select 1.0 %.
10)Influence of the xylitol additive amount to hollow humilis preserved fruits quality
Xylitol is in the agricultural crops such as corncob, is a kind of sweetener of natural health prepared by by deep processing.Wood The sugariness of sugar alcohol is 95 % of sucrose, and xylitol can participate in body metabolism as a kind of functional sweetener, into blood Afterwards, it is not required to that insulin can penetrate cell and accretion rate is fast, blood glucose rise will not be caused, be most suitably adapted for diabetic population Edible auxotype carbohydrate substitute.
Although xylitol has sugariness identical with sucrose and heat, but xylitol, unlike sucrose, blood can be made by overeating Liquid neutral fat increases, and body is made to get fat.On the contrary, appropriate xylitol is eaten for a long time, there is control body weight and reduce fat Effect adjust the metabolism of lipid because xylitol can reduce the free fatty in blood, thus make adipose tissue generation subtract It is few;Xylitol has the function of inhibiting glycerine, neutral fat, free fatty synthesis, thus can control the weight of human body, rises To the effect of weight-reducing.Xylitol can not only anti-caries, not blood glucose increasing, and have the function of liver protecting, this is exclusive in sugar alcohol Kind.
As shown in Figure 11, when xylitol additive amount is 40 %, the sensory evaluation scores highest of hollow humilis preserved fruits, when xylitol adds When amount is higher or lower than 40 %, sensory evaluation scores drastically decline, and illustrate the additive amount of xylitol to the qualities of hollow humilis preserved fruits extremely It is important.Xylitol additive amount is very little, and sugar can be made only to be wrapped in hollow plum surface, can not oozed, led to preserved fruit peracid, influence sky The mouthfeel of heart humilis preserved fruits;And the additive amount of xylitol is too many, may result in preserved fruit and crosses sweet tea, influences the mouthfeel of preserved fruit, to influence The organoleptic quality of hollow humilis preserved fruits.Therefore, hollow humilis preserved fruits xylitol additive amount is 40 %, and under the additive amount, preserved fruit is sour-sweet It is palatable, there are the unique fragrant of hollow plum, the preserved fruit mouthfeel of gained best.
