Two cultivars of chokeberry - ‘Nero’ and Polish ‘Galicjanka’ are sold in Poland. Sometimes, there are also present the seedlings of ‘Viking’ and ‘Hugin’ cultivars. In the experiment some morphological characteristics, the quality of fruits and chemical composition of four chokeberry cultivars (‘Galicjanka’, ‘Hugin’, ‘Nero’, ‘Viking’) were compared. Chokeberry plants were grown at the Experimental Station of Pomology Department at the West Pomeranian University of Technology in Szczecin. Fruits collected from ‘Hugin’ cultivar shrubs were the smallest (100 fruits weight was 32 g) and the least juice was obtained from them (73.6%); however, they were characterised by the highest content of soluble solids (18.7°Bx), titratable acids (1.05 g), polyphenols (2340 mg), especially cyanidin 3-galactoside as well as nitrates (98.5 mg) and nitrites (1.87 mg). The ‘Hugin’ cultivar was characterised by light-coloured fruits, and, as a result, by light-coloured juice. Fruits of ‘Galicjanka’ cultivar were the biggest, 100 fruits weight was 111,7 g. In fruits of the ‘Nero’ and ‘Viking’ cultivars, the content of individual components was at the lowest level. These cultivars have the largest amount of substances colouring fruits, pulp as well as red and blue juices, are also the darkest and the dark juice was obtained from them. Maceration of fruit pulp resulted in a significant change of colour of the juice obtained, it become darker and had a more intense blue colour.

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>

The main objective of the study was to standardize enrichment of aonla pulp to develop fruit bars. The experiment was laid out in Completely Randomized Design (CRD) with 10 treatments. Aonla pulp was blended with 25 to 75% of different fruit (mango, papaya and jackfruit) pulp viz. Aonla pulp, Aonla with mango, papaya and jackfruit in different proportion of 3:1, 1:1 and 1:3 each fruit respectively. The initial moisture content was higher in aonlapulp enriched with mango pulp in 1:3 proportions. Enrichment of aonlapulp with fruit pulp of mango, papaya and jackfruit reduced the ascorbic acid, titratable acidity and tannin content of the resultant fruit bars compared to that from pure aonla pulp, which is an indication in the reduction of astringency. Enrichment also resulted in an increase in total soluble solids, reducing, non-reducing and total sugars of the resultant fruit bars. Enrichment of aonla pulp with fruit pulp of provitamin A rich fruits like mango, papaya and jackfruit showed a rise in total carote-noids and reduced astringency and acidity, thereby resulting in fruit bars with altered palatability and enhanced nutrition. Enriched fruit bars contained three vital antioxidants viz. Vitamin C, carotenoids and polyphenols of all the treatments, enriched fruit bar containing 25 % aonlaand 75 % mango (T4) was found superior in organoleptic evaluation.

The variability of characteristic components of aronia (Aronia melanocarpa, black chokeberry) and to evaluate the chemical composition and quality of aronia products in order to complete the already available data and to facilitate authentication of fruit products were estimated. The mean values obtained for the set of aronia fruits were: soluble solids 19.9 &deg;Brix, titratable acidity 9.8 g malic acid/kg, formol number 11.9 ml 0.1M NaOH/100 g, ash 6.7 g/kg, phosphorus 0.34 g/kg, potassium 2.90 g/kg, calcium&nbsp; 0.27&nbsp;g/kg, magnesium 0.16 g/kg, sucrose 0.10 g/kg, glucose 47.1&nbsp;g/kg, fructose 37.8 g/kg, sorbitol 66.1 g/kg, malic acid 9.6 g/kg, citric acid 1.0 g/kg, quinic acid 5.0 g/kg, isocitric acid 0.02&nbsp;g/kg. These values can potentially be a useful tool to determine aronia content in foodstuffs or to determine adulteration of other fruit-based products with aronia. The most promising markers appeared to be the content of sorbitol, quinic acid and characteristic profile of anthocyanins measured by HPLC. &nbsp;

Given the increase in the production, commercialization andconsumption of fruit pulp in southwest Piauí state (PI), Brazil, research is needed to gain information on the composition of products already on the market. As such, this study aimed to assess the quality of fruit pulp based on standards established by current legislation. The pulps studied were acerola, cajá, cupuaçu, guava and passion fruit, which were thawed and homogenized. The samples were stored with three replications and the following assessed: total soluble solids (TSS), tritratable acidity (TA), pH and total vitamin C. The TSS (°Brix) and TA (% citric acid) values in acerola, cajá, cupuaçu, guava and passion fruit pulps were 5.20º and 1.02%, 3.20º and 0.86%, 13.24º and 2.42%, 4.80° and 0.64% and 6.20º and 2.41%, respectively. The pH values of acerola (3.00) and cupuaçu (3.02) pulps were in line with legislation (Ordinance 58, of August 30, 2016), whereas cajá (2.05), guava (2.72) and passion fruit (2.72) were below the established limit. With respect to vitamin C, acerola (1015.42 mg per 100 g), cajá (49.60 mg per 100 g), guava (29.0 mg per 100 g) and passion fruit (22.25 mg per 100 g) were in accordance with legislation, where as cupuaçu was below the legally stipulated content (11.68 mg per 100 g). All the pulps studied had at least one characteristic that did not meet the minimum legal requirement, which can be resolved by adopting good manufacturing practices that comply with legislation.

The aim of this paper is to evaluate the yield and quality of 'Pérola' pineapple under increasing rates of nitrogen and potassium applied through fertigation. The experiment was conducted in a randomized block design, with four replications, in a factorial scheme (4x4), which represents four nitrogen rates (128, 256, 384 and 512 kg ha-1 of N) and four potassium rates (192, 384, 576 and 768 kg ha-1of K2O) via fertigation. The evaluations consisted of physical and chemical fruit characteristics and yield. Increasing nitrogen rates provided linear growth on fruit production features and the rate of 516 kg ha-1 resulted in fruits with the largest diameters. The highest total yield on 'Pérola' pineapple crop was reached on plants under the supply of 498 kg ha-1 of K2O. Rates between 523 and 583 kg ha-1 of K2O, provided the largest fruit matter and the highest fruit pulp yield. The increasing amount of nitrogen applied by fertigation resulted in linear growth on fruit pulp pH, though it did not influence the soluble solids content. The lower acid content and higher SS/acid ratio on fruits were reached with the N rates of 333 and 375 kg ha-1 respectively.
