The effect of pre-harvest and post-harvest aloe vera gel treatments on fruit quality and storage performance of table grapes

This study investigated the impacts of pre-harvest, post-harvest, and combined pre-harvest+post-harvest Aloe vera gel treatments on various quality parameters of the ‘Red Globe’ grape cultivar during a 150-day storage period. The quality parameters assessed were weight loss, decay ratio, color attributes, firmness, soluble solids content (SSC), titratable acidity (TA), levels of total phenolics and total antioxidant capacity, as these are indicative of bioactive compounds. Post harvest Aloe vera treatment resulted in the lowest weight loss among three treatments, while the combined treatment surprisingly led to the highest weight loss. Pre-harvest treatments resulted in the lowest SSC values, while the combined treatments led to the highest values. Differences in TA value were not statistically significant, neither between treatments nor during the storage period. Storage duration alone significantly affected pH values. The Aloe Vera treatments significantly increased total phenols compared to the control group, and this increase remained consistent throughout the storage period. The combined treatments yielded the highest total phenols (3389.45 µg gallic acid equivalent/g fresh fruit). Similarly, Aloe Vera treatments significantly increased total antioxidant capacity (TAC) throughout the storage period. While the combined treatment yielded the highest TAC on day 150 (6.66 µMol trolox equivalent/g fresh weight), it negatively affected physical and chemical parameters. However, compared to other treatments, this combined approach significant boosted phytochemical levels. These findings suggest that for fresh table grapes, separate pre-harvest or post-harvest Aloe Vera treatments might be preferable. On the other hand, for those prioritizing elevated phytochemical content for health benefits, the combined application offers an option despite its drawbacks.

Pre-storage calcium chloride and aloe vera gel coatings mitigate internal browning and senescence scald in ‘Conference’ pears

Physiological disorders pose significant challenges to the quality and shelf life of ‘conference’ pears. This study investigates the efficacy of calcium chloride (CaCl2) and aloe vera (AV) gel treatments in reducing internal browning and senescence scald in ‘Conference’ pears. Four groups were evaluated: a control, individual 2 % CaCl2, 15 % AV gel treatments, and a combined CaCl2 and AV gel treatment. Pears having following maturity indices (TSS 12 %, ho 90, and Firmness 67 N) were then stored at 2 ± 1 °C, 85±5 % RH for 180 d The fruits were removed from cold storage to room temperature and kept at 20±3 °C and 65±5 % RH followed by physicochemical and sensory analyses. The combined treatment proved most effective in preserving quality and reducing internal browning and senescence scald. Treated pears displayed reduced respiration rates, ethylene production, internal browning, senescence scald, and weight loss. Moreover, the combined treatment resulted in higher TA and lower TSS compared to the control after 180 d of storage. The reduction in internal browning and senescence scald can be attributed to enzyme activity modulation. The combined treatment increased catalase (CAT) and superoxide dismutase (SOD) activity, reducing oxidative stress. This, in turn, minimized oxidative reactions leading to internal browning. Furthermore, the treatment inhibited polyphenol oxidase (PPO) and peroxidase (POD) activity, enzymes responsible for browning reactions. Lower PPO and POD activity contributed to reduced internal browning and senescence scald. The combined actions of enhanced antioxidant enzymes and decreased browning-related enzymes synergistically reduced internal browning. In conclusion, the combined CaCl2 and AV gel treatment effectively mitigated internal browning and senescence scald in pears and also received the highest score in sensory analysis. Enhanced antioxidant enzyme activity (CAT and SOD) and reduced PPO and POD activity collectively contributed to this reduction. This eco-friendly approach presents a sustainable strategy for extending shelf life and enhancing pear quality, providing an alternative to traditional chemical interventions for managing physiological disorders.

Effect of Aloe vera gel coating on organoleptic and nutritional quality of minimally processed carrot.

Demand for fresh vegetables has led to development studies in postharvest area mainly focused on minimizing and look for alternatives to chemical additives for food preservation. The use of natural derived edible coatings emerges as a promising alternative for maintaining quality of vegetables. The objective of this study was to evaluate the effect of Aloe vera gel in minimally processed carrot during postharvest storage. Samples with different degrees of processing were immersed in Aloe vera gel, packaged polyolefin bags, and stored in refrigerated chambers at 5 °C for 12 days. Different organoleptic and quality parameters were evaluated. In general, the samples treated with Aloe vera gel showed less quality loss and a lower increment in the bleaching index. Moreover, sensory analysis allowed to establish that carrots processed in slices and shredded and coated with the gel had a more flavorful taste and higher moisture content. Aloe vera treatment did not influence the microbiological growth of bacteria and fungi during storage. Regarding nutritional quality, the treated samples showed a higher accumulation or lower degradation of phenols, flavonoids, and carotenoids, probably generating in this way, a higher antioxidant capacity in these samples. Finally, Aloe vera gel treatment did not influence sugar dynamics in any of the samples. It can be concluded that the treatment with Aloe vera gel allows maintaining a better organoleptic and nutritional quality of carrots with different degrees of processing during refrigerated storage.

Use of novel postharvest Aloe vera gel coating for suppression of ripening changes in Asian pears during long‐term cold storage

SummaryThe impact of Aloe vera gel (AVG) coatings (0%, 25%, 50% and 75%) was evaluated on the ripening‐related quality parameters in ‘Patharnakh’ pear fruit during long‐term cold storage (0 ± 1 °C and 90–95% RH). Results showed that AVG coating extended the storage life of fruit by minimising mass loss, decay index, respiration rate, polyphenol oxidase activity, softening enzyme activities like pectin methylesterase (PME) polygalacturonase (PG) and cellulase and maintaining the preliminary sensory quality (SQ), firmness, soluble solid content (SSC), total phenols, titratable acidity (TA) over the control. Among all AVG treatments, 75% AVG treatment was found most promising for suppressing mass long, lowering respiration rate and preserved overall fruit quality up to 60 days of cold storage in ‘Patharnakh’ pear fruit. Hence, AVG proved as an alternative to non‐edible coatings for extending the pear's marketable span and cutting down the adverse effects of health and environmental hazards.

Assessment and characterization of postharvest handling techniques in the value chain of Malay apple (Syzygium malaccense [L.] Merr. & L.M. Perry) in the Mount Cameroon region

The study examined the problem of excessive postharvest losses (PHLs) of Malay apples due to inadequate postharvest handling, which is hindering the growing demand for the fruit. The study surveyed 160 growers and 40 traders using semi-structured questionnaires to assess postharvest handling practices and propose storage techniques in the Mount Cameroon Region. Data were obtained via face-to-face interviews using semi-structured questionnaires. The data were analysed using descriptive and inferential statistics. Also, the effects of control (no application), hot water dip, 1-MCP, and Aloe vera gel treatments on the quality of Malay apples stored at room temperature for 24 days were examined using a completely randomised design. Chi-square results showed a significant (p< 0.05) association between sociodemographic factors [gender (χ2 = 25.004, p = 0.050), educational level (χ2 = 63.797, p = 0.034), and farming experience (χ2 = 48.87, p = 0.047)] and PHLs. Results showed that inadequate postharvest handling was leading to excessive PHLs, and appropriate postharvest techniques were necessary to maintain the fruit's quality and reduce losses. Significant differences were observed among harvesting, transportation and storage methods, packaging materials, and marketing methods, with harvest and storage showing higher PHLs of 40% and 35%, respectively. The study also found that 1-MCP and Aloe vera were effective in extending the storage life of Malay apples while maintaining quality. The study concluded that growers and traders should adopt proper postharvest techniques in their operations, including handpicking, and application of 1-MCP or Aloe vera gel coating to reduce PHLs and maintain fruit quality for 12 days. Overall, the study highlights the importance of better postharvest handling practices and storage techniques to reduce postharvest losses and improve the supply chain's efficiency. Future research could explore the applicability of these findings on other fruits and geographical locations, and investigate the underlying mechanisms that contribute to the effectiveness of these treatments.

Experimental Study of Using Aloe Vera Gel to Treat Diabetic Chronic Cutaneous Ulcers in Bama Miniature Pigs

To investigate the efficacy, safety, and mechanism of topical application of aloe vera gel (AVG) to treat diabetic chronic cutaneous ulcers in Bama miniature pigs. The Bama miniature pig model of diabetic chronic skin wounds was constructed and the model pigs were randomly assigned to AVG daily administration group (AVG QD), aloe vera gel every-other-day administration group (AVG QOD), and diabetic control group (DC). A non-diabetic chronic skin wounds model pig was set as the non-diabetic control group (NDC). Treatment efficacy was evaluated based on the amount of time needed for complete healing of the wounds, healing rates, granulation growth rates, and skin histopathological changes. Safety was evaluated according to whether adverse reactions were observed. In addition, the dynamic changes of the relative expression levels of miR21, miR29a, miR126, miR146a, miR155, and miR210 in wound granulation tissues were examined. 1) Efficacy and safety: The amount of time needed for complete healing of the wounds was shorter in the NDC group than those of the three other groups, DC group, AVG QD group, and AVG QOD group (all P<0.05). The amount of time needed for complete healing of the wounds was shorter in the AVG QD group and AVG QOD group than that of DC group (all P<0.05). The amount of time needed for complete healing of the wounds was shorter in the AVG QOD group than that of AVG QD group (all P<0.05). No adverse reactions were detected in the whole process of AVG topical treatment. The granulation growth rate of NDC group was higher than those of DC group, AVG QD group, and AVG QOD group (all P<0.05). The wound healing rate of NDC group was higher than those of DC group, AVG QD group, and AVG QOD group (all P<0.05); the wound healing rate of AVG QOD group was higher than those of DC group and AVG QD group (all P<0.05). 2) Histopathology: The results of HE staining light microscopy showed that collagen fiber production increased, and that microvascular formation with slight inflammatory cell infiltration was observed in the dermal interstitium at the initial stage of wound healing after AVG treatment. One year of after complete healing, pathological examination results of wound healing skin showed that the epidermal keratinization was complete, that collagen was arranged neatly and orderly, and that many microvessels were found in the interstitium. The results of picric acid celestite scarlet staining showed that, after AVG treatment, type Ⅰ collagen mainly increased in the initial stage of wound healing, type Ⅲ collagen gradually increased when the wound healed completely, and the collagen was arranged neatly during the whole process. 3) The relative expression of microRNAs: The relative expression of miR21, miR126, and miR210 in NDC group, AVG QD group, and AVG QOD group were higher than that in DC group (all P<0.05). The relative expression of miR29a and miR155 in NDC group, AVG QD group, and AVG QOD group was lower than that in DC group (all P<0.05). The relative expression of miR146a in NDC group was higher than that in DC group ( P<0.05). AVG topical application can shorten the time needed for complete healing of diabetic chronic wounds in Bama minipigs. The wound healing speed of the alternate-day treatment group was faster than that of the daily treatment group. No adverse reactions were observed over the course of the treatment. The mechanism may be related to the up-regulation of the expressions of miR21, miR126, and miR210 and the down-regulation of miR29a and miR155 in wound granulation tissue.

Extending vase life of carnation flowers by postharvest nano silver, humic acid and Aloe Vera gel treatments

Abstract Standard Carnation flowers (Dianthus caryophyllus cv. Dover) were harvested at the paint brush stage in the early morning, pre-cooled at 4° C for 6-h then moved under dry conditions to the laboratory. Flowers were weighted and treated for 24-h with silver nanoparticles (AgNPs) at 0, 5 or 10 ppm in plastic buckets. After pulsing treatments, cut flowers were transferred to 500 mL glass jars containing 300 mL of preservation solution treatments including, individually, humic acid at 200, 400 or 600 ppm and Aloe vera gel at 2.5%, 5.0% or 7.5% (w/v) till the end of the experiment (when flower color began to fade, petals began to roll). Distilled water was used for the control and to prepare the tested solutions. 2% sucrose was added to all treatments including the control. Addition of all preservatives to vase solutions significantly increased all the studied characteristics of cut flowers compared to control (distilled water, least values). Nanosilver treatments have the potential to be used as preservative solutions for improving postharvest vase life and quality of carnation flowers. An increment in vase life, relative fresh weight, vase solution uptake, flower diameter as well as total chlorophylls in leaves, total carbohydrates and total phenols in leaves and petals was observed, in addition to a decrease in bacterial counts in vase solution. Best results were obtained using 5 ppm AgNPs + 5.0% Aloe vera gel followed by 5 ppm AgNPs +7.5% Aloe vera gel solutions. Aloe vera gel, especially 5.0% level, showed better results than humic acid when used alone or combined with AgNPs. Nanosilver at 5 ppm recorded better results than 10 ppm when used as a single treatment.

The Use of Aloe vera Gel on Scar Collagen

Aloe vera have active chemicals substances including saponins, tannins, flavonides, and polyphenols. Saponin takes a role as a disinfectant, so it is normally effective for healing any open wounds, while tannins have ability to be an antiseptic. This study aims to see how the effect of the Aloe vera gel on wound collagen, and too inspect which is the most effective concentration of the Aloe vera gel in the formation of wound collagen in wistar strains (Rattus novergicus) rats. This study uses a post-test only method with control group design. The subjects of this study were 28 male Wistar rats (Rattus novergicus). The subjects were divided into 4 groups consisting of 1 negative control group and 3 treated groups, the control group was not given any treatment, while the treated group was given the Aloe vera gel with each concentrations of 12.5%, 25%, and 50% respectively. The experiment was started by making a wound on the back of the rat which then be followed by applying the gel to the wound for 14 days. The results showed the group with the 50% Aloe vera gel treatment had the best collagen formation, followed by a concentration of 25%, 12.5%, and the control group. Therefore, the used of Aloe vera has given good change in scar collagen, and the best scar collagen can be viewed in the group with 50% concentrate of Aloe vera.

Nutritional and Antioxidant Properties of Mango Juice and Aloe Vera Gel and their Effect on Diabetic Rats

Aloe vera gel contains several vitamins and minerals, which make it rich in antioxidants and aid in managing different chronic conditions. Aloe vera, along with other fruits, is used to produce many fruit beverages. Therefore, the present work was designed to investigate effects on the sensory, nutritional, and antioxidant properties of the juice from various combinations of Aloe gel (7.5, 15, and 25 percent) with mango juice. Some biochemical parameters of streptozotocin-induced diabetic rats were also recorded for the effects of aloe gel, mango juice, and their combination. Sensory tests showed lower acceptability for juices with a content of 25 percent Aloe vera, while other scores obtained were good and deemed satisfactory. Calcium and chromium content in 25 percent aloe vera gel treatment was significantly (p&lt;0.05) highest for mineral content, while phosphorus, potassium, and magnesium content were lower compared to other treatments. Results also showed that mango juice content of the antioxidant activity, phenols, and flavonoids increased with rising gel concentration in the blends. The administration of aloe-mango juice has resulted in a significant decrease in serum glucose and total cholesterol compared with other diabetic groups. A significant decrease in serum levels of AST, ALT, and ALP in animals receiving Aloe-mango juice relative to mango juice group was observed. Furthermore, Aloe-mango juice treatment ameliorated the oxidative stress as demonstrated by a substantial decrease in the serum MDA level in the treated group as opposed to the diabetic mango juice group. These findings of the present investigation support the use of Aloe gel for elevating the nutritional properties of the supplemented juices; it can be recommended to consume these juices as part of a healthy diet, especially for diabetic persons.

The Healing Effect of Aloe Vera Gel on Acetic Acid-Induced Ulcerative Colitis in Rat.

BACKGROUND The use of herbal and synthetic compounds can be effective in improving the areas and repair of tissues that have been affected during the processes like what happens in ulcerative colitis (UC) as a common inflammatory disorder. According to the beneficial effects of aloe vera, in this study, we aimed to assess the therapeutic effects of oral aloe vera gel on acetic acid-induced colitis in rats by histopathological and molecular analysis of Bax, and BCL-2 genes expression (using RT-PCR technique) in colon tissue samples. METHODS This experimental study comprised 32 adult male Sprague Dawley rats weighting 220 ± 20 g that were randomly divided into four groups as follows. The control group (healthy rats), colitis group in which UC was induced by transrectal administration of 3% acetic acid with no treatment, oral form of sulfasalazine group in which UC was induced by transrectal administration of 3% acetic acid, then was treated by oral administration of sulfasalazine 500 mg/kg body weight, and the fourth group which received oral form of aloe vera gel (200 mg / kg) for 21 days, respectively after induction of UC. Then, the therapeutic effects of treatment groups were compared with the control group and the colitis group with no treatment, by the assessment of histopathological and molecular changes in the colon tissues of rats on the 7th, 14th, and 21st days. Finally, the collected data were analyzed using statistical tests. RESULTS Histologically, aloe vera gel treatment could reduce and heal colon tissue damages in induced colitis. Also, this gel reduced apoptosis in rat’s colon with acetic acid-induced colitis, which showed in significantly decreased in Bax mRNA expression and significantly increased BCL-2 mRNA expression compared with the colitis group with no treatment. CONCLUSION Aloe vera gel has a significant effect on the treatment of UC in rat because of the beneficial effect that was found from aloe vera such as decreasing the severity of colitis as evidenced by histopathological findings, and with respect to apoptosis and gene expression that were related to wound healing process, and suppression of the elevation of Bax mRNA with the upregulation of Bcl-2, which can be considered effective in the treatment of UC.

Effect of gum arabic and Aloe vera gel based edible coatings in combination with plant extracts on postharvest quality and storability of ‘Gola’ guava fruits

Guava is an important climacteric fruit that exhibits short shelf life at ambient conditions. Due to short shelf life, marketing and subsequent storage of guava is difficult. Therefore, some treatments that can extend shelf life and conserve quality of guava fruits are required. In the present work, the effect of ginger extract, garlic extract, gum arabic and Aloe vera gel coating (in combinations) was investigated on guava fruits at 25 ± 3 °C for 15 days. The combination of garlic extract + gum arabic markedly suppressed weight loss, skin browning and disease severity. In addition, fruits of garlic extract + gum arabic treatment had higher titratable acidity and this combination also suppressed excessive increase in total soluble solids till the end of storage period compared with control. Similarly, garlic extract + gum arabic combination significantly extended shelf life of guava fruits as compared with control. Garlic extract + gum arabic treatment showed significantly higher ascorbic acid content and lower total sugars. In contrast, reducing sugars were lower in gum arabic + Aloe vera gel treatment and non-reducing sugars were lowest in ginger extract + gum arabic coated guavas. Antioxidant activity and antioxidant capacity were not affected with any combined treatment but these were comparatively higher in gum arabic + Aloe vera gel treatment. In contrast, total carotenoids were higher in ginger extract + gum arabic combination while total flavonoid contents were higher in garlic extract + gum arabic coated guava fruits. In conclusion, combined application of garlic extract and gum arabic could be considered a suitable treatment for shelf life extension and quality conservation of guava fruits.

Possible use of organic compounds on shelf life and quality properties of peeled pomegranate.

Pomegranate cultivar (“Ardestani”) peeled and packed in polyethylene containers and treated with different natural products. Two concentrations of Aloe vera gel (10 and 15%), two different levels of saffron petal extracts (10 and 20% V/V) and two concentrations of saffron style extract (0.1 and 1% V/V) and control in one storage condition (7°C and 85% RH) were the treatments that applied by a full factorial randomized method. We examined natural substances for their possible application in extending the shelf life of fresh‐cut horticultural products to find a new approach for packaging and exporting pomegranates. About 13.8% mass loss in the 12th day of storage occurred because of higher enzymatic activity and lower membrane resistance. Our results show that all treatments significantly reduced mass loss, and Aloe vera gel treatments combined with saffron petal extract were the best. Although all treatments decreased ion leakage, Aloe vera gel and saffron petal extract reduced it significantly. Ion leakage incidence of arils at day 12 was lower in Aloe vera gel and saffron petal extract treatment compare to control. Application of both saffron extracts on arils reduced decay incidence and chilling injury from 86.67% to 6.67% and 60% to 26.67%, respectively. Total acidity, soluble solids content, total phenol content, anthocyanin content, and antioxidant capacity of arils changed differently in different treatments, and saffron petal extract significantly was the best one and increased anthocyanin content, total phenol content, and antioxidant capacity in arils. The microbial contamination increased in more extended storage, although both saffron extracts were successfully suppressed mold and bacteria growth below acceptable limits in 14 days at 7°C.

Aloe vera gel coating delays post-cut surface browning and maintains quality of cold stored lotus (Nelumbo nucifera Gaertn.) root slices

Post-cut surface browning is the leading constraint in shelf life extension and marketing of fresh-cut slices of lotus roots. In the current work, efficacy of Aloe vera gel (AVG) coating on quality and post-cut surface discoloration of lotus root slices was investigated. The slices were coated with 0, 25 and 50% AVG concentrations and kept at 5 ± 1 °C for 8 days. The slices coated with 50% AVG concentration showed substantially higher overall visual quality with markedly lower weight loss, browning degree, total aerobic bacteria and activities of polyphenol oxidase and peroxidase enzymes. Relative electrolyte leakage, hydrogen peroxide, superoxide anion and malondialdehyde content were also significantly lower in 50% AVG gel coated slices. Similarly, 50% AVG treatment had substantially higher total phenolic content and superoxide dismutase, ascorbate peroxidase and catalase enzymes activities. So, 50% AVG concentration is suitable to reduce enzymatic browning and to conserve overall quality of lotus root slices.

Aloe vera gel treatment delays postharvest browning of white button mushroom (Agaricus bisporus)

Postharvest browning is the limiting factor for the storage of white button mushroom (Agaricus bisporus). Aloe vera has been shown to have a wide range of physiological effects in horticultural produce. To investigate the role of Aloe vera coatings on mushroom quality and browning during storage, button mushrooms were treated with Aloe vera gel (0, 25, 50 or 75%) and stored at 4 °C for 15 days. The results showed that treating the mushrooms with Aloe vera gel before storage, lowered weight loss and the levels of surface browning and also increased superoxide dismutase activity, total phenolic content and 1,1-diphenyl-2-picrylhydrazyl scavenging activity. Moreover mushrooms treated with Aloe vera gel treatments also maintained lower thiobarbituric acid-reactive substances, hydrogen peroxide (H2O2) and hydroxyl radical (–OH) and decreased polyphenol oxidase activity compared with non-treated mushrooms. These results showed that pre-storage treatment with Aloe vera gel decreased white button mushrooms browning during cold storage and that the optimum treatment was 50% Aloe vera gel for maintaining the quality of button mushroom during storage.

Processed Aloe vera gel attenuates non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal injury by enhancing mucin expression.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are well-known for exerting numerous adverse effects on the gastrointestinal tract such as bleeding, ulceration, and perforation, thereby limiting their use. Most previous studies have focused on NSAID-induced gastropathy. However, improved diagnostic techniques have recently highlighted NSAID-induced small intestinal ulcers, which have so far been underestimated. While proton pump inhibitors are prescribed to control NSAID-induced gastropathy, few preventive strategies are existent for NSAID-induced small intestinal injury, thus requiring new methods to treat these enteropathies. Numerous studies have reported the beneficial biological effects of Aloe vera, such as wound healing, anti-cancer, immune modulation, anti-oxidant, anti-microbial, and gastroprotective effects. A previous report on the effect of Aloe vera against NSAID-induced ulcers studied only gastric ulcers and elucidated the results as an anti-inflammatory effect of Aloe vera. However, ulcer prevention cannot be justified entirely to be due to the anti-inflammatory effects of Aloe vera, since NSAIDs themselves also exert an anti-inflammatory reaction. We therefore investigated the anti-ulcer effects of Aloe vera on the small intestine, especially focusing on mucin expression. Our results indicate that processed Aloe vera gel (PAG) treatment attenuates not only the severity of intestinal ulcers but also bacterial translocation, by enhancing the mucus layer in the indomethacin-induced small intestinal damage mouse model. We further confirmed that PAG positively regulates the mucin expression in the LS174T human cell line, mainly via the ERK-dependent pathway. We propose that PAG application is a potential strategy for the alleviation of NSAID-induced small intestinal ulcers.

Post-harvest factors affecting quality and shelf life of mango cv. Amropali

A study was conducted to investigate the effect of some postharvest treatments on shelf life and quality of mango. Experiment was conducted at the BAU Germplasm centre, Department of Horticulture, Bangladesh Agricultural University, Mymensingh during May to July, 2013. Two treatments viz. Aloe vera and Chitosan solution were used for this study. The experiment was laid out in Completely Randomized Design (CRD) to observe the post-harvest performance of mango with three replications. The fruits were divided into three grades eg. large, medium and small for the convenience of the experiment. In each group mango were treated with Aloe vera gel and Chitosan solution in three different concentrations of 0.5%, 1% and 1.5%. Amropali cultivar had the highest shelf life (7days) at 1.5% Aloe vera gel treatment to the large size mangoes at room temperature compare to other sizes and treatments. Nearly, similar effect was obtained from 1.5% Aloe vera gel to the medium size fruits than other treatments. 1.5% Chitosan showed the second best result in case of shelf life extension followed by 1% Chitosan solution.Res. Agric., Livest. Fish.3(2): 279-286, August 2016

An Innovation for Retarded Healing Process of a Chronic Ulcer by Aloe Vera Gel Treatment

In some cases of chronic ulcers of soft tissue cannot be treated by conventional treatment methods. In recent years some alternative methods have been proposed for treatment of such ulcers on the basis of Traditional Iranian (Persian) Medicine. This reports a case of chronic ulcer treatment by using &lt;em&gt;Aloe vera&lt;/em&gt; gel. The ulcer was caused by car accident and in spite of using conventional treatment the injury remained for 60 days without appropriate response to therapy. Because of stopping in healing process by Aloe vera gel, this was discontinued and potassium permanganate has been used. After drying the ulcer using the alternative method of &lt;em&gt;Aloe vera&lt;/em&gt; gel and potassium permanganate together has been applied and then the &lt;em&gt;Aloe vera&lt;/em&gt; gel was used until the complete healing of ulcer. The delayed healing process of &lt;em&gt;Aloe vera&lt;/em&gt; gel raise the question whether it is solely effective in complete healing of chronic ulcer or requires adjuvant therapies. Although &lt;em&gt;Aloe vera&lt;/em&gt; is effective in healing process of chronic ulcer but sometimes it may be ineffective so that we are obliged to use potassium permanganate as an adjuvant drug which is presented by this case report.
