ABSTRACT We assessed the effect of neutral electrolyzed water (NEW) on the incidence of rot on tomato (Solanum lycopersicum L.) fruits inoculated with Fusarium oxysporum, Galactomyces geotrichum, and Alternaria sp. at sites with lesions. The inoculated fruits were treated with NEW at 10, 30, and 60 mg liter−1 active chlorine, with copper oxychloride fungicide, and with sterile distilled water (control) for 3, 5, and 10 min. In the experiment with F. oxysporum, 50 to 80% of the control fruits and 50 to 60% of the fruits treated with the fungicide exhibited symptoms of rot at the inoculated sites. The lowest incidence recorded was 30% for fruits treated with NEW at 60 mg liter−1 active chlorine with an immersion time of 5 min. In the experiment with G. geotrichum, incidence of rot on control fruits was 70 to 90%, and for treatment with fungicide rot incidence was 50 to 90%. NEW at 60 mg liter−1 active chlorine significantly reduced incidence of symptomatic fruit: only 30% of the inoculated fruits washed for 5 min had damage from rot. In the experiment with Alternaria sp., 60 to 90% of the fruits in the control group and 60 to 70% of the fruits in the fungicide group were symptomatic. The lowest incidence was recorded for the treatment in which the fruits were submerged in NEW with 60 mg liter−1 active chlorine for 3 min. In this group, 40 to 50% of the fruits exhibited symptoms of rot. These results were obtained 8 days after inoculation. NEW, with 60 mg liter−1 active chlorine, significantly reduced incidence of rot symptoms on fruits inoculated with one of the experimental fungi relative to the control (P ≤ 0.05). NEW at 60 mg liter−1 is effective in the control of fungal rot in tomatoes.

Diabetes Mellitus is a chronic disease caused by abnormal working insulin, insulin secretion or both so that the body tends to have high glucose levels. Type 2 diabetes mellitus can cause elevated levels of LDL and cholesterol. Risks obtained by fetuses with type 2 diabetes can be in the form of macrosomia due to hyperglycemia and hyperinsulin in the body of the fetus. Insulin is the first choice pharmacological therapy for type 2 DM that can be given during pregnancy. Non-pharmacological therapy as recommended by the World Health Organization (WHO) on a healthy diet by increasing consumption of fruits and vegetables. Good fruit consumed for pregnant women with diabetes mellitus (DM) type 2 is tomatoes (Solanum lycopersicum L). The purpose of this study was to determine the administration of tomato extract (Solanum lycopersicum L) and insulin can affect glucose levels, LDL levels, cholesterol levels and birth weight of white wistar galur (Rattus norvegicus) pregnant women with type 2 diabetes mellitus models. experimental design using the pre post test only control group design and post test only control group design. Termination was done on the 17th day of pregnancy and then followed by measurements of LDL levels, cholesterol and birth weight. Data analysis using the One Way Anova test and Kruskal Wallis then continued with the Post Hoc test using. The results showed that there were significant differences between glucose levels, LDL levels, cholesterol levels and BW born in the insulin treatment group and the tomato juice treatment (p value = 0.00 <α = 0.05). The conclusion of giving insulin and tomato juice affects a decrease in glucose levels, LDL levels, cholesterol levels and birth weight.

Postharvest Loss

Tomato (Solanum Lycopersicum L. (or) Lycopersicon esculentum Mill.) is being a very nutritious and health protective food, are highly perishable nature. Its sensitivity to postharvest loss due to poor handling, diseases and physical injury limits its successful marketing. Therefore, simple technology is required to reduce the postharvest loss of this commodity. The use of edible coatings with bio-extracts appears to be a good alternative preservation technique to extend the mature tomato fruits. This study was, therefore, initiated to investigate the effect of using bio- extracts garlic bulba and capsicum incorporation with coating materials (maize starch and beeswax on physicochemical quality of tomato fruit stored at ambient conditions (temperature 15.5 to 20.2oC and relative humidity of 55.5 to 67.3%). The experiment was conducted using complete randomized design of two varieties (Fetane and Melkashola) and six treatments. The tomato fruits were coated by dipping into solution for 3 minutes. The treatments prepared were on coating solution of MGE( 9.5% maize starch with 0.5% garlic extract), MCE (9.5% maize starch with 0.5% capsicum extract), BCE (9.5% beewax mixed with 0.5% capsicum extract), BGE (9.5% beewax mixed with 0.5% garlic extract), 10% maize starch without bio-extract, 10% beewax without bio- extract and control. The treatment means were tested at significance level of P ≤ 0.05. The effectiveness of bio-extracts with coating materials on physicochemical quality of tomato fruits were evaluated at three days intervals for 30 days. There was a significance difference (P<0.05) between coated and uncoated fruits. All coatings delayed tomato ripening and improved the keeping quality parameters but best results were exhibited by 9.5% with 0.5% BCE followed by 9.5% with 0.5% MGE by maintaining the mature tomato fruit for 30 days. The study showed that the Fetane variety has maintained more quality attribute than Melkashola variety during storage.

Nutrient Solutions

Tomato (Solanum lycopersicum L.) is an important vegetable in the country which is consumed both raw and as processed product. This study aimed to evaluate the growth, yield, postharvest qualities and profitability of aquaponically grown tomato supplemented with different nutrient solutions. The study was laid out in Randomized Complete Block Design with 8 treatments replicated 3 times. Tomato fruits were first harvested 60 days after transplanting with 100 percent survival rate. Early flowering of tomato plant was observed when applied with VSU liquid nutrient formulation (VSU-LNF) with node number ranging from 13.33-14.00 bearing the first flower. Growth parameters such as plant height, number of lateral shoot, root length and fruit size are stimulated by the application of VSU liquid nutrient formulation and in combination with ferments. This also resulted to high number and weight of marketable fruit in tomato plant. Carotenoid and chlorophyll contents of the fruits were higher in aquaponically grown tomato supplemented with fermented kuhol (Pomacea canaliculata L.). Free radical scavenging activity was found highest in the fruit of tomato grown in aquaponic system supplemented with combined VSU liquid nutrient formulation with fermented malunggay (Moringa olifera). However, vitamin Cand sugar content of tomato fruits were found highest when supplemented with combine VSU liquid nutrient formulation and fermented kuhol. No significant differences were obtained on firmness, percent weight loss, respiration rate at 2 and 4 weeks after storage, titratable acidity, fruit nitrogen, pH of fruit, oxidation reduction potential, electrical conductivity and total dissolved solids. On the other hand, higher moisture content of the tomato fruits were observed with the application of VSU liquid nutrient formulation and in combination with ferments. Therefore, high yield was produced with the application of VSU liquid nutrient formulation which resulted to higher net return. Aquaponically grown tomato supplemented with VSU-LNF produced lesser yield but with considerable net return.

Numerous studies have been conducted on the effect of various beverages on the mechanical properties of toothcolored materials, however, little is known about the effects of these materials on composites, particularly newer types such as nanocomposites. Objectives: This study aimed to evaluate the surface microhardness of two types of composites, micro-hybrid (point 4) and nanohybrid (premise), after exposure to natural and industrial juices. Methods: In this experimental study, 90 disc-shaped specimens with a thickness of 2 mm and a diameter of 10 mm were taken from two composites, micro-hybrid Point4 (Kerr) and nanohybrid premise (kerr) (two groups of 45). Then, the specimens of each group were divided into 5 subgroups of 9 and were immersed for 7 days for 6 hours in 5 solutions of industrial orange juice, natural orange juice, industrial pomegranate juice, natural pomegranate juice, and distilled water (control group). Surface microhardness of specimens was measured by Vickers device at baseline, one day and one week after immersing. Data was measured by ANOVA, repeated measure test, and independent t-test. A significant level of α was 0.05. Results: The surface microhardness of two types of composites exposed to beverages was reduced significantly. However, no significant difference was found between natural and industrial juices in none of the composites. Conclusions: Natural and industrial juices can affect the surface microhardness of composites, which varies depending on the type of composite and the type of juice and immersion time.

The effect of water deficit on concentrations of carotenoids was investigated in ripening tomatoes using HPLC-PDA. Fifteen different tomato cultivars were grown under three levels of water supply and unripe and fully-ripe fruits were harvested at different stages. Water deficit significantly affected several morphological and fruit yield-related parameters. In unripe tomato fruits, the relative concentrations of xanthophyll cycle carotenoids, e.g., violaxanthin and antheraxanthin, were significantly increased at the expense of ?-carotene upon limiting the water supply. In ripe fruits, nutritionally-relevant lycopene, ?-carotene and lutein levels were broadly independent of water deficit when considering all 15 cultivars, although significant variations were observed among fruits from different genotypes. Our study highlights the importance of careful genotype selection for the production of tomatoes rich in nutritionally-relevant compounds like lycopene and ?-carotene.
