The food industry requires natural colouring agents in increasing quantities. Beet root is highly adapted to this purpose with its red (betacyanin) and yellow (betaxanthin) pigments suitable for numerous products. The two pigments are, however, very heat-sensitive depending not only on the method of drying as well. In our experiment we tested 6 table beet varieties with vacuum drying (instrument: Eurovac KIT-150) and obtained very big differences in the suitability of varieties for drying. The less colour loss was measured in Bordó (16.84%), while Rubin and Cylindra indicated 45.15 and 47.18% loss respectively. During the drying raw material with higher colour content produced higher rate of pigment loss (r = 0.880). In our experiment we found adverse effects on colour material and dry matter content in the fresh beet root. The variety with higher solids (mainly sugar) resulted in higher pigment loss (r = -0.847) during the vacuum drying process. Furthermore, we stated that the yellow pigments (betaxanthin) were less heat sensitive during drying than the red (betacyanin) ones. For the production of beet root powder varieties of high pigment content but low water soluble solids content (sugar) are needed.

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.

Control fruits and fruits subjected to 1-MCP application were placed in cold storage at 2°C, 90% r.h. for 18 weeks. The susceptibility of ten apple cultivars: ‘Beni Shogun’, ‘Braeburn Hillwell’, ‘Elise’, ‘Gloster’, ‘Golden Delicious’, ‘Idared’, ‘Jonagold Decosta’, ‘Ligol’, ‘Mutsu’ and ‘Šampion’ was tested using an impact test to obtain bruising of fruits. The analyses were performed on fruits immediately after harvest and four times after different period of cold storage (9 and 18 weeks) and shelf-life (7 days). The following analysis and characteristics of apples were determined: soluble solids content, dry matter content, acidity, fruit mass and size, and firmness. Impact test was carried out by dropping a glass ball with a mass of 25.68 g from height of 40 cm, due to which kinetic energy value of 0.1 J was obtained. Slight differences in acidity and soluble solid content were observed. On the other hand, stress noticed at firmness test was significantly higher for fruits treated with 1-MCP. It was also observed that firmness decreases after the shelf-life and after storage of fruit at room temperature. The ‘Beni Shogun’ apples fruits stored for 9 weeks are most susceptible to bruising (volume = 438.26 mm3). After cold storage, less susceptible cultivar was ‘Szampion’, for which the volume of fruit bruise was 145.62 mm3 only. After 9 weeks of cold storage, for most cultivars, there was no significant differences in bruise volume; however, the shelf-life had significant influence by differing the cultivars, and for all studied cultivars, the bruise volume was lower.

Late Sowing

In our trial morphological and quality parameters of 15 table root varieties were tested at 3 different sowing dates: 15 April, 9 July and 19 August 2010. In the trials the root shape of the varieties form the April sowing date approached most the regular spherical shape (diameter/length –1.0) which is favoured both by fresh market and the processing industry. In the July and August sowings the roots were elongated with reduced proportions. The highest red pigment content (betacyanin) was observed in the second sowing of July (>80 mg/100 g). In the late sowing (August, under plastic tent) a further 10–20 mg/100 g pigment increase was measured in relation to the earlier sowing dates of the same varieties. A similar trend could be observed in yellow pigments (vulgaxanthis) which proves a close correlation between the quantities of the 2 pigments (r=0.823). The highest vulgaxanthin content (103.3–124.18 mg/100 g) was obtained form roots of the late sowing harvested in December. Varieties reacted differently to temperature and so to sugar accumulation in the different sowing periods. In the July sowing higher water soluble solids content was measured on the mean of varieties (10.12 %) as compared to the April sowing (7.76%). Sensory evaluations included inner colour intensity (1–5), with ring (1–3) and taste (1–5) of the raw material evaluated by scoring. According to laboratory measurements better inner colour intensity was observed in the July and August sowing dates. In these samples uniformly coloured, almost with, ring-free roots were obtained. In our trial varieties from the spring sowing had superior taste. Early sowing is recommended for fresh market sale while the second crop (July) harvested in autumn can satisfy processing requirements. In the late sowing (under unheated plastic tent) fresh beet root can be grown at the end of autumn or beginning of winter, thus prolonging the usability of plastic tents.

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.

SUMMARYThe effect of three levels of N fertilizer on the ensiling characteristics of S. 24 perennial ryegrass and S. 37 cocksfoot have been examined during first growth in two growing seasons. The effects of sucrose supplementation, inoculation with Lactobacillus plantarum and wilting were also examined in certain cuts. All silages were made in the laboratory using a small scale vacuum silage technique.The perennial ryegrass herbage was higher in water soluble carbohydrates than the cocksfoot, N fertilizers decreased soluble carbohydrates and dry-matter content in both species. Buffering capacity was not consistently different between grasses or between N levels.Herbage was cut at two stages of maturity in the first year. In the first cut (8 days before ear emergence), perennial ryegrass silages were well preserved irrespective of the amount of N applied to the grass. Cocksfoot silages were well preserved only when the lowest level of N fertilizer had been applied (50 kg/ha). Supplementation of cocksfoot with sucrose prior to ensiling markedly improved silage quality, but inoculation had no effect. In the second cut (26 days after ear emergence) the grasses were higher in drymatter content and showed a lower buffering capacity, but neither ryegrass nor cocksfoot silages were well preserved unless supplemented with sucrose prior to ensiling.In the second year of the experiment only one cut was taken (9 days after ear emergence). As in the previous year, silages made from herbage at a late stage of growth were poorly preserved. Wilting prior to ensiling resulted in well-preserved silages.It is concluded that the need for additives and wilting to ensure satisfactory preservation varies in relation to the variety of grass used and its stage of growth.

Brewing industry generates a main residue, brewers’ spent grain (BSG), which has good properties both for use in animal consumption and for thermal use, but contains a very high content of moisture (20–25% dry matter content), so that its elimination or treatment should be immediate, since it can cause degeneration problems of the product. Currently, brewers often supply this material at low cost for use as livestock feed. This solution is not efficiently carried out without reporting too much benefit to the brewers more than to eliminate waste from their facilities. However, BSG is a raw material of interest for application in different areas due to its low price, availability throughout the year and a valuable chemical composition, so it seems necessary to look for an alternative use to give value to these characteristics. In this paper a drying study is carried out in order to establish the foundations for its energy use by thermal of BSG. BSG has been used from a craft brewery located at Badajoz, Spain. Drying analysis was carried out for various temperatures and inlet air flow by means a convective dryer. The properties studied show that BSG can be used for thermal utilization in large installations, being necessary heat drying processes as a pretreatment in order to obtain a biofuel with acceptable efficiency.
