Vegetable, due to higher neutraceutical component, are termed as protective food against various major and minor diseases. Scientific agro-techniques under optimum growing condition like temperature, relative humidity and light intensity, positively influence the qualitative and quantitative attributes of most of the vegetable crops including cherry tomato. It is one of potential vegetable crop, which is extensively utilized for table purpose and for preparing recipies in five star restaurants. Cherry tomato fetches higher prices in market due to good taste and higher nutrients, thus making qualitative attributes as an important factor to give higher returns to the farmers. Thus, this experiment was conducted to estimate the qualitative attributes in eighteen genotypes of cherry tomato grown under both open field and polyhouse conditions. The result of the study revealed that under open field condition, BRCT-30 was the best genotype with maximum value for lycopene content (6.62 mg 100-1 g FW) and β-carotene (2.30 mg 100-1 g FW), second maximum value for total soluble solids (7.85°Brix), third maximum value for reducing sugar and fourth highest position for ascorbic acid content (43.65 mg/100 g FW). Under polyhouse condition, the best genotype for quality parameters was BRCT-36 with maximum total soluble solids (10.81°Brix), lycopene (7.48 mg 100-1 g FW) and β-carotene (2.49 mg 100-1g FW) along with average range of values for ascorbic acid (72.36 mg 100-1 g FW) and titrable acidity (0.55 mg 100-1 g FW).

Extraction of tropical fruit juice using simple, efficient, and environmentally friendly technologies is gaining importance to produce high quality juices. Juice from pink-fleshed guava, pink-fleshed pomelo, and soursop was extracted using direct and indirect thermosonication methods by varying intensity, time, and temperature, and compared to those extracted using water bath incubation. Improvised models of juice yield, ascorbic acid, and total soluble solids responses were generated by eliminating insignificant model terms of the factors in full quadratic model using backward eliminating procedure. Main effects, 3D, or 4D plots for each response were developed based on factors that influenced the response. Results showed that the best extraction method for guava and pomelo juices were within indirect thermosonication method of 1 kW, 55 °C and 30 min, and 2.5 kW, 54 °C and 23 min, respectively. Direct thermosonication method at 10% amplitude, 55 °C for 2 to 10 min was more suitable for soursop juice. Thermosonicated extraction of tropical fruit juice can improve its juice yield, ascorbic acid content, and total soluble solids content.

The effect of applying Ca++ in two forms: infiltration and dipping on mango fruit cv `Haden' was investigated. This effect was evaluated by measuring some quality parameters in the flesh and in the skin of the fruit. It was found that postharvest application of Ca++ extent the storage life of the fruit by a week. This fact, together with the results obtained from the quantification of sugars, ascorbic acid, total soluble solids alcohol. insoluble solids, starch and titrable acidity seem to indicate that the application of Ca++ delays slightly the process associated with ripeness. Furthermore, no significant difference between the two forms of Ca++ applied was found, except for the amount of ascorbic acid and total sugar. Finally, dipping application of Ca++ is easier than infiltration and it is therefore suggested.

Pineapple is a food rich in vitamins, antioxidants and bromelain, but because it has high water content it becomes a highly perishable fruit. Hibiscus is a plant with flowers rich in phytochemicals that can be used as an ingredient to add value to processed products. The objective of this work was to prepare mixed jams using pineapple with hibiscus extract at different concentrations and to characterize the physicochemical properties of the jams produced. Experimental design was completely randomized with four replicates. The treatments consisted of three concentration levels of hibiscus extract (5, 10 and 15%) in pineapple jelly (50:50). Analyzed physical-chemical characteristics were: water content, water activity, ash, lipids, total sugars, reducing and non-reducing sugars, vitamin C, total titratable acidity, pH and total soluble solids. It was found that increasing concentrations of hibiscus in the formulations significantly influenced resulting jam composition. Increasing hibiscus concentration reduced the total sugars content and increased ascorbic acid content, acidity, total soluble solids and ash, as well as total anthocyanins and flavonoids contents. Among the jams produced, the formulation with 15% hibiscus was distinguished by its high content of ascorbic acid, flavonoids and anthocyanins. The addition of hibiscus to pineapple jelly improves the nutritional and functional value of the resulting jams, so it can be considered a high potential ingredient for this type of product.

ABSTRACT The family farming from the Borborema Territory-PB, Brazil, produces sweet oranges that supply the regional market. In this context, it is necessary to define standards of identity and quality, as well as to quantify the bioactive compounds in the fruit, in view of adding value and creating more competitive markets. This work sought to evaluate the quality, bioactive compounds and total antioxidant activity (TAA) of oranges from family farming. A 3x3 factorial completely randomized design was used, with three cultivars (Baía, Comum, Mimo-do-Céu) and three maturity stages (predominantly green, green/yellow, yellow), with 60 replications of 1 fruit for the physical evaluations, and 4 of 15 fruit for the others. The whole fruits were evaluated by color index, length, diameter, fresh weight and firmness. The juice was assessed for yield, pH, soluble solids (SS), titratable acidity (TA), SS/AT ratio, and ascorbic acid. Total extractable polyphenols (TEP) and ABTS•+ and DPPH• total antioxidant activity (TAA) were measured in the juice and albedo. The 'Baía' and 'Mimo-do-Céu' oranges presented quality parameters aligned with the CEAGESP standards. On average, the ascorbic acid content was higher than 45 mg 100 g-1, with ‘Mimo-do-Céu’ presenting the highest content (50.26 mg 100 g-1). During maturation, the firmness decreased, and the SS, TEP and TAA of the juice and the albedo increased. In general, the TEP content was about eight-fold higher in the albedo than juice, corresponding to the much higher TAA in this portion, thereby highlighting its higher functional potential, especially for ‘Baía’ orange.

Aims: To determine the suitable combination of fertilizers for obtaining high quality fruits from Kinnow orchard. Study Design: The experiment was conducted in randomized block design with three replications per treatment on Kinnow mandarin. Place and Duration of Study: The experiment was conducted on seven years old earmarked plants at Experimental Orchard and in Post-harvest Technology Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar, Haryana, India during the year 2016-17. Methodology: The treatments comprising of 11 combinations of Urea, K2SO4, ZnSO4, FeSO4 and boric acid which were laid out in randomized block design with three replications. Seven years old uniformly grown trees spaced at 6x6 m were selected for the present study and analyzed for yield and quality parameters such astotal soluble solids (%), acidity (%), ascorbic acid (mg/100 ml juice), juice content (%), TSS to acid ratio etc. Results: In comparison to other fertilizers combinations, the maximum fruit yield per plant (97.83 kg/plant), juice content (49.47%), total soluble solids (9.80%), TSS to acid ratio (11.95) and ascorbic acid content (32.30mg/100ml) and minimum acidity (0.83%), rag (24.00%) and peel content (25.60%) and peel thickness (3.42 mm) were registered with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%, however, the foliar spray of Urea, K2SO4, ZnSO4, FeSO4 and boric acid had no effect on number of seeds per fruit in Kinnow mandarin. Thus it is clear from results that foliar nutrient application showed a stimulating influence on yield and quality parameters of Kinnow fruits. Conclusion: From the research findings it can be concluded that the maximum potential of Kinnow mandarin plants in respect of fruit yield per plant, juice content, total soluble solids, TSS to acid ratio and ascorbic acid content was exploited to a maximum level and the acidity, rag and peel content and peel thickness to a minimum level with foliar application of Urea 1.0% + K2SO4 1.0% + ZnSO4 0.5% + FeSO4 0.5% + H3BO3 0.2%.

Floating row covers are important pre-harvest factors for maximizing the yield of vegetable crops grown under open-field conditions. It is necessary to replace oil-based nonwoven covers with biodegradable ones that are environmentally friendly. The aim of this study was to investigate the effects of biodegradable nonwoven covers, made of aliphatic-aromatic copolyesters, with or without fatty acid dimers (SB20/13, SB21/13, and SB28/13), on yield and chemical composition of ‘Glacier’ and ‘Swift’ winter onions. In the first experiment, we observed a higher total marketable yield and higher harvest index for onions covered with SB21/13 (by 24% and 3%, respectively) when compared to the control (polypropylene nonwoven). The SB20/13 cover significantly decreased mean bulb weight by 15.3% than in control. Bulbs harvested from the plots covered with SB21/13 had lower dry weight by 3.2-3.7% and those covered with SB28/13 showed the lowest L-ascorbic acid content when compared to all other treatments (by 6.3-10.3%). The lowest total sugar content was found in control onion bulbs, but it was significantly different only from bulbs covered by SB20/13, which had more sugar by 10.6%. In the second experiment, plants covered with the SB28/13 had a 1 st grade yield of onions higher by 47% than that of the control. The highest mean bulb weight was obtained from plants covered with the SB21/13 nonwoven. Covering with nonwovens caused a decrease in dry weight (SB20/13 and SB21/13, by 1.3-1.7%, respectively) and L-ascorbic acid (all nonwovens, by 15.6% for SB21/13 up to 22% for SB20/13) in onion bulbs in comparison to the control. Since the tested biodegradable nonwovens covers did not cause any decrease in the yield of winter onions compared to polypropylene nonwovens, the former appear to be a suitable environmental-friendly solution for the open-field cultivation of this important vegetable crop.

Micronutrients, particularly Iron (Fe) and Zinc (Zn), play a vital role in the growth and development of plants due to their catalytic effect on many metabolic processes. However, the biochemical responses to the applied micronutrients vary with cultivars and their species. A screening experiment was conducted during 2020 to know the antioxidants enzyme activities and biochemical constituents in response to iron and zinc fertilization by six capsicum hybrids grown in grow bags under shade net conditions. The experiment consists of three treatments viz., Control (No Fe & Zn), 50 kg FeSO4 and 37.5 kg ZnSO4 ha-1 as a basal soil application with six capsicum hybrids viz., Indra, Priyanka, Inspiration, Massilia, Bachata, and Local green. Leaf samples of the capsicum hybrids were collected at Fruiting stage and analysed for antioxidant enzyme activities. The fruit samples were used for quantifying the biochemical constituents. The results revealed that, application of ferrous sulphate (FeSO4) and zinc sulphate (ZnSO4) to capsicum hybrids increased the biochemical constituents in fruits and the antioxidant enzyme activities in leaves. Out of the six hybrids tested, Indra possessed higher ascorbic acid content (9.20 mg 100 g-1 fresh weight), acidity (6.0), and total soluble solids (6.10 Brix) in the fruits, which was followed by Inspiration and Bachata. The superoxide dismutase (6.70 unit’s mg-1 protein) and peroxidase (6.90 unit’s g-1 fresh weight) activities were also higher with the same genotypes. The biochemical constituents and antioxidant  enzyme  response to Zn addition was better than Fe.  There was 13.2, 10.9 and 9.5 per cent increase in titratable acidity, total soluble solids, ascorbic acid content in the fruits of Indra due to ZnSO4 application.The Principal Component Analysis (PCA) and hierarchical clustering revealed that Indra is highly responsive to Zn and Fe fertilization, while the local green showed very less response. The rest of the genotypes such as Inspiration, Bachata, Massilia, and Priyanka, are medium responsive for Zn and Fe fertilization.

Ultrasound treatment is recognized as a potential technique for improvement in the nutritional values of fruit juices. This study was initiated with the objective of evaluating bioactive compounds and some important quality parameters of black (BC), red (RC) and white (WC) currant juices obtained from fruit mash preliminarily treated by enzymes combined with ultrasound. Individual and total phenolic content (TPC), anthocyanins, color parameters, ascorbic acid, antioxidant capacity (TEAC), juice yield, pH, titratable acidity, and soluble solids were investigated. Significant increases in the levels of TPC and antioxidant capacity of sonicated samples were observed. However, ultrasound treatment had no effect on individual phenolic compounds of juices. Sonication of mash before juice pressing did not cause any noticeable changes in ascorbic acid content. Only in the case of WC was an increase in content of vitamin C noticed. The color of juices obtained after treatment was similar to the control sample. It was demonstrated that enzymatic combined with ultrasound treatment of mash for different colored currant fruit did not have any dismissive effect and could even improve some parameters of the juice obtained.

Abstract The current research focuses on changes of physically-chemical parameters of 'Nante' carrot hybrids during storage in traditional conditions. Quality parameters during carrot storage for six months at temperature 8 ± 2 oC and relative air humidity 85 ± 1 % were evaluated using standard methods: soluble solids (digital refractometer), dietary fibre (AOAC 985.29), ascorbic acid (iodometric) and firmness (TA.XT.plus Texture Analyser). Before storage, hybrids 'Nante/Berlikum', 'Nante/Maestro' and 'Nante/Bolero' had higher soluble solid content: 1.6 times higher comparing with hybrid 'Nante/Forto' and 1.2 times higher compared with hybrid 'Nante/Champion'. These hybrids also had higher ascorbic acid content: 2.0 times higher than in 'Nante/Forto' and 'Nante/Champion'. Significant differences were not found in dietary fibre content and firmness of non-stored carrots. Substantial differences were observed in soluble solid content in the hybrid 'Nante/Berlikum' during six-month storage - the content decreased 2.0 times. However, nonsignificant decrease of soluble solids content decreases was found for the hybrid 'Nante/Forto'. Changes in hybrid firmness and dietary fibre amount were not significant during storage for four months. Ascorbic acid content of the carrot hybrids during storage decreased by 3.4 times.
