Investigations were carried out in 2013. A. kolomikta cv. ‘Laiba’, ‘Lankė’, ‘Landė’, ‘Paukštės Šakarva’ fruits were picked at the technical maturity stage. The amount of dry matter, soluble solids and texture parameters were established in fruits after harvesting and during storage. Fruits stored for 8 weeks in controlled atmosphere chambers with different air parameters (No. 1–21 % O2, No. 2–0.5 % O2, No. 3–1 % O2, No. 4–1 % O2 and 1 % CO2). Dry matter, soluble solids and texture analysis were done biweekly. The amount of dry matter was determined by drying the samples to the constant mass at the temperature of 105 ºC. Soluble solids content was determined by the refractometric method. Fruit texture parameters were analysed by Texture analyser. The results of chemical analysis at harvest time showed that the biggest amount of dry matter and the highest value of flesh firmness were in ‘Laiba’ fruits, soluble solids in ‘Landė’ fruits. The highest value of bio-yield point was established in ‘Paukštės Šakarva’ fruits. Results of analysis showed that dry matter content as well as soluble solids content of A. kolomikta fruits increases during storage in controlled atmosphere chambers. The highest increase in soluble solids content was in chamber No. 4 and the highest increase in dry matter content was in chamber No. 2 compared with fruits at harvest time. A. kolomikta fruits texture changes during fruit ripening with bio-yield point and flesh firmness declining. The largest decrease of bio-yield point and flesh firmness of fruits occurred in two weeks of storage.

Abstract Rowanberries (Sorbus aucuparia) are small orange-red fruits of a rowan tree. They have been described as an important source of flavonoids, and their antioxidant activity affects reactive oxygen species and lipid peroxidation. Cultivars of sweet rowanberries and hybrids with other species are sweeter and less astringent than wild rowanberries. The aim of the current study was to determine physical and chemical properties of sauces from various cultivars of wild and sweet rowanberries, and mixes of sweet rowanberries with pumpkins, and to assess their degree of acceptance. The experiments were carried out at the Faculty of Food Technology of the Latvia University of Agriculture. The sauces were made from purees of wild rowanberry and sweet rowanberry cultivars and purees of sweet rowanberry with apple or pumpkin using different species. The content of total dry matter, soluble solids, total carotene, pH, colour L* a* b* values and texture parameters were determined in samples of the sauces. The results showed large variability between the rowanberry and rowanberry-pumpkin sauces. The total dry matter content of sauce samples varied from 25.92 to 31.38%, the total carotene content from 3.94 ± 0.40 to 7.34 ± 0.57 mg 100 g-1 DM, and firmness from 0.5 to 2.2 N. According with sensory evaluation the panellists liked (P < 0.05) sauces samples made from rowanberry ‘Michurinskaya krasnaya’ puree and from ‘Granatnaya’ and pumpkin purees.

Abstract The average vitamin C content of fresh carrots was 56 mg.kg-1. Amount of vitamin C was reduced by the length of storage and storage environment. On average, the most significant decrease in vitamin C to 24.4 mg.kg-1 under laboratory conditions was reported after 56 days when stored carrots were packed in plastic box. When stored in a refrigerator, the vitamin C content decreased to 24.7 mg.kg-1 after 126 days of storage in a plastic box. During both experimental periods in laboratory conditions, the most vitamin C was preserved while being wrapped plastic wrap. This way of packaging also enabled relatively long-term preservation of freshness in variety called “Komarno”, which was up to 60 days. The second best option in this respect is the packed carrot in microtene bags. The least convenient was to store the carrots open without packaging. In the case of refrigerated storage, the options of packaging in plastic wrap and microtene bags were also the best. The most significant decline in vitamin C was found in the variant without packaging and in the food box. Average soluble solids (refractometry dry matter) content in fresh roots reached 7.6%. During storage under laboratory conditions, the SS values increased to 14.8% after 14 days when the carrot was stored open without packaging. In the refrigerator, the soluble solids content in carrots increased to 12.7% after 28 days of storage without packaging. Increase in soluble solids content was mainly caused by transpiration process. Under laboratory conditions, evaporation and increase of soluble solids were faster compared to the variants stored in the cooler

A field study was conducted to determine the relationship between pungency, soluble solids content, and susceptibility to neck rot in onions. `Golden Cascade', `Sweet Amber', `Valdez', and `Vega' onions were planted in a field with low soil S content. Sulfur, as coarse-ground calcium sulfate, was applied as a band before planting. After harvest, yield was determined and a sample of jumbo onions was taken from each plot to determine pungency, dry matter content, and soluble solids content. Healthy bulbs were returned to storage and evaluated for neck rot after 4 months. Yield, grade, and neck rot incidence after storage were not affected by S treatments. However, there was a trend toward lower neck rot incidence at the highest S application rate (160 lb/acre). Pungency of jumbo onions increased after the application of S as gypsum. `Sweet Amber' and `Valdez' were less pungent than `Golden Cascade' or `Vega'. Neck rot susceptibility was evaluated with an inoculation test of detached bulb scales. Growth and sporulation of the neck rot pathogen Botrytis allii were reduced by S application. Pungency and neck rot susceptibility were negatively correlated.

ABSTRACT Sweetpotato (Ipomoea batatas) is a root crop grown in many countries. This tuberous root is a source of energy, nutrients, and phytochemicals. In this study, bioactive compounds and physical and physicochemical qualities of sweetpotato genotypes were evaluated. Eight new genotypes of sweetpotato produced by Embrapa Hortaliças (orange-fleshed: MD09026-OF and MD09024-OF; cream-fleshed: MD09011-CF, MD09004-CF, MD10039-CF, and MD10004-CF; yellow-fleshed: MD09017-YF and MD12002-YF) and two cultivars used as controls (Beauregard and Brazlândia Roxa) were evaluated for color, soluble solids, dry matter, phenolic compounds, total carotenoids and β-carotene. Hue angles differed even between those sweetpotatoes with the same flesh color. The orange-fleshed genotypes MD09024-OF, MD09026-OF, and Beauregard, had the lowest L*, showing to be darker than the others. These sweetpotatoes also had the brightest flesh colors with higher C*. The orange-fleshed genotypes MD09026-OF and MD09024-OF were sweeter (10.55oBrix and 9.23oBrix) than Beauregard (5.12oBrix). Brazlândia Roxa had the highest dry matter content (38.05%), followed by the genotypes MD10004-CF, MD09017-YF, MD09026-OF MD10039-CF, and MD09011-CF, which showed similarity, ranging from 32.33% to 29.12%. The highest contents of total carotenoids were found for the orange-fleshed genotypes MD09026-OF (80.06 mg g-1) and MD09024-OF (70.56 mg g-1) and Beauregard (73.12 mg g-1). These same genotypes showed the highest total phenolic compounds (0.815 mg g-1 and 0.686 mg g-1, respectively). MD09026-OF showed the highest content of β-carotene (46.47 mg g-1). MD09026-OF was the most prominent genotype among those evaluated, as it showed the highest total carotenoid, β-carotene, phenolic compounds, and soluble solids content, in addition to a high dry matter content.

SUMMARYPoultry manure and mineral fertilizers at two rates of application (medium and high) and in different combinations, together with a non-fertilized control, were tested at the Experimental Station of the Agricultural University of Padova, Italy (45° 21′ N, 11° 58′ E) in 1985–89.Compared to the control, all the fertilization treatments increased the incidence of larger-sized bulbs of onion and tubers of potato, improved the fruit colour of processing tomato and the raw protein content of spinach, but reduced the acidity and acids: soluble solids ratio of tomato and the dry matter content of spinach leaves.In addition, the application of 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as mineral fertilizer or as poultry manure gave the best scores of processing suitability of potato, both for sticks and chips. All the fertilization formulae, except for 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as poultry manure alone, showed significant decreases in the extractable sucrose ratio in sugarbeet, compared with the control. In processing tomato, the best scores of suitability for paste transformation were obtained with mixed fertilization (1/3 poultry manure and 2/3 mineral fertilizers) applying 210 kg/ha of N, 210 kg/ha of P2O5 and 150 kg/ha of K2O and the plots receiving only mineral fertilizers produced fruits with less favourable values of pH and electrical conductivity compared to the poultry manured ones.
