Introduction:One of the major problems in the juice industry is the loss of the fruit aroma during the thermal concentration techniques. During this process, the water evaporation, which carries the volatiles, compromises the juice’s flavor. In the fruit juice concentration by vacuum evaporation, the aqueous fraction with the volatiles is composed of only one phase.Methods:This study analyses the volatiles of the aqueous fractions from the concentration of mango and guava juices in a vacuum evaporator under different temperatures. The volatiles from the aqueous fractions were analyzed using mass spectrometry and the sensorial analysis evaluated the fruit aroma intensity.Results:Eighteen volatiles were identified in mango juice, among them, monoterpenes, sesquiterpenes and ketones were the major ones. The major compounds found in both mango juice and its aqueous fractions were 3-carene, β-pinene, β-terpinene and limonene. In the volatile profile of the aqueous fraction from the guava juice, the predominant compounds were aldehydes, such asn-hexanal and, the alcohol eucalyptol. 24 compounds were identified, including alcohols, sesquiterpenes, esters and ketones, and all characteristic volatiles were present in the guava fruit. Under the different temperature and vacuum conditions, the loss of vitamin C ranged from 35 to 77% for mango and from 15 to 55% for guava juices.Conclusion:Aqueous fractions collected early in the concentration under different temperatures were richer in the distinctive fruit odor when compared with the fractions collected at the end of the process. The loss of vitamin C was higher at higher temperatures and vacuum applied.

Global Prevention

Anemia is a problem of MMR in Indonesia. based on the global prevention of Anemia, the prevalence of anemia in pregnant women is 28.3%. The anemia rate in Rangkap Jaya Health Center is 64.3%. Anemia occurs due to physiological changes and is aggravated by malnutrition. Efforts that can be done so that pregnant women do not experience anemia are consumption of Fe tablets, improve diet and add vitamin C-rich food substances such as those found in red guava fruit and beets. This study aims to determine the differences in the administration of red guava fruit juice (Psidium Guajava) and beet juice (Beta Vulgaris) to hemoglobin levels in anemic pregnant women at Puskesmas Rangkapan Jaya Depok. Methodology this study uses a Quasy Experiment design with a Two Group Pretest Posttest Design. The population in this study are all trimester III pregnant women. The samples of this study arev30 people with the intervention of red guava juice and beet juice. Given for 14 days which are 250 cc. The sampling technique used is purposive sampling. Results: That there are differences in the provision of red guava juice and beet juice on hemoglobin levels in pregnant women. With the average value before and after administration of red guava fruit juice is 8.4 g / dl to 11.5 g / dl and the average value before and after beet juice is 8.5 g / dl to 10.2 g / dl. p-value of 0.001. The conclusions is Red guava juice is more effective against changes in hemoglobin levels.

Subtropical Fruit

Guava (Psidium guajava L.) is a lovely tropical and subtropical fruit that originates in Mexico, Central America, and then taken to other distant and near parts around the world. In Sudan this popular fruit is produced in orchards and household and is so profitable but yet attacked by a lot of fruit fly species of the Genera Ceratitis and Bactrocera and the result is a loss of more than 70%. This research aimed at evaluating the effect of Gum Arabic coating (GAC) in extending the shelf life of guava fruit and disinfesting it from these notorious pests. Guava fruits from Kadaro orchards, Khartoum North, were tested using seven concentrations of Gum Arabic solutions. The results reflect that 1: 4 (25%) and 1: 8 (12.5%) (GA: water) concentrations attained 56 and 40% disinfestation, respectively whereas the other lower concentrations effected corresponding results in a range from 20 – 08%. The reduction in maggots per test fruit reached upto 188% as compared to the control.  The highest concentrations (1: 4 & 1: 8) effected a sustainability of 52% in fruit firmness (FF) with an average of medium (3) FF compared to soft FF (4) in the control. The corresponding results in other lower concentrations (1: 16; 1: 32; 1: 64; 1: 72 & 1: 96) were 36, 24, 24, 20 and 16%, respectively. In addition to an average FF of 4 (soft) for all these concentrations and 5 (very soft) for all the corresponding controls. Nevertheless, the sustainability of fruit color (FC) effected by the test concentrations was 52, 44, 24, 22, 24, 20, and 24%, respectively. Regarding these results, the two highest test concentrations effected a sizeable disinfestation and control of fruit flies and a good extension of shelf life of guava in Khartoum State. These findings support using this treatment as an effective IPM tool to extend guava fruit shelf life and upgrading its postharvest quality.

Hypertension is a disease that is not uncommon in the community, including the Bukit Lau Kersik village. People with hypertension often do not show long-term symptoms and can be life-threatening. However, one of the management of hypertension that can be used as non-pharmacological therapy is consuming starfruit juice and cucumber which is quite easy to find in the Bukit Lau Kersik village. This combination of juices contains potassium which can reduce blood pressure in patients with hypertension. This study used Equivalent Time Sample Design with 14 subjects with hypertension in the Bukit Lau Kersik Village, Gunung Sitember Subdistrict, Dairi District. The technique of this research sample used Non-Probability Sampling with Saturated Sampling. The instrument used was a sphygmomanometer and a stethoscope. Bivariate data analysis in this study was the Wilcoxon statistical test. Based on the data analysis performed, the value of p = 0.011 (p= < 0.05) was obtained, meaning that there was a significant relationship between giving star fruit juice and cucumber to hypertensive patients. Then it can be concluded that there is an influence between giving star fruit and cucumber juice to blood pressure reduction in hypertensive patients in Bukit Lau Kersik Village Gunung Sitember Subdistrict, Dairi District in 2019. Suggestion: The factors that affect blood pressure in hypertensive patients and checking blood pressure before drinking star fruit juice and cucumber.
