Objective: To study the effect of storage temperatures and dehydration conditions (solar and convective drying; SD, CD), on the quality, physicochemical parameters and antioxidant properties of tomato fruits. Methodology: The physicochemical characteristics pH, titratable acidity, soluble solids (°Bx) and color parameters (L*, a* and b*), were evaluated. The lycopene, carotenoids and antioxidant activity percentages retention of tomatoes fruits stored at 7 and 22 ° C for 5 days and subjected to SD (Temperature (T) of 67 °C and luminescence of 685 lum/sqf) and CD (T 70 °C, flow rates 0.5, 1.0 and 1.5 m/s), were analyzed. Results: The fruits reached humidities of 17 and 15% for SD and CD. The parameters pH, °Bx, L*, a*, b* were highest with 22°C and CD (1.5 m/s). The value of the carotenoids was higher in fruits stored at 7 ° C and subjected to CD (1.0 and 1.5 m/s) and SD with values of 83.85, 85.98 and 99.43%, respectively. The CD (0.5 m/s) and SD improved lycopene (94.37 and 95.14%) and the antioxidant activity with values of 73.06 and 97.21%. Implications: The application of solar dehydration depends on luminescence condition; however, it is inexpensive and environmentally friendly alternative. Conclusions: The results derived in a viable alternative for the conservation and commercialization of tomato fruits in rural communities

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.

Solanum Lycopersicum L

Free radicals can cause damage to human skin, so antioxidants are needed to counteract the negative effects of these free radicals, for example preparations in the form of face masks. For tomatoes (Solanum lycopersicum L.) contains nutritious substances, namely lycopene which can be useful as an antioxidant in the skin. This study aims to determine the effect of variations in kaolin and bentonite bases on physical characteristics and antioxidant activity of tomato lycopene extract clay mask, and to determine the best formula. Tomato lycopene extract (Solanum lycopersicum L.) was modified into a microemulsion preparation to keep antioxidant activity stable. Kaolin and bentonite which were used as bases had various concentrations in each formula, namely F1 15% and 2%, F2 20% and 1.5%, F3 25% and 1%, F4 30% and 0.5%, respectively. The results showed that the four clay mask preparations were homogeneous and did not change in color, shape and aroma. The pH test on the four formulas is F1 4.33 ± 0.35, F2 5.58 ± 0.24, F3 6.48 ± 0.22, F4 7.34 ± 0.08. The viscosity test on the four formulas, namely F1 20213.3 ± 140.4, F2 24133.3 ± 83.26, F3 29080 ± 105.83, F4 33293.3 ± 378.06. The spreadability test was F1 6.59 ± 0.24, F2 5.59 ± 0.16, F3 4.85 ± 0.11, F4 7.84 ± 0.05. The test time for the preparation to dry was F1 19.02 ± 0.36, F2 15.33 ± 0.54, F3 11.27 ± 0.42, F4 8.24 ± 0.50. Easy-to-clean tests i.e. F1 and F2 are very easy to clean, F3 and F4 are easy to clean. The best formula for clay masks is the F3 preparation where the concentration of kaolin is 25% and bentonite is 1%.
