“…A total number of 32 volatiles were identified from the pummelo juices based on their matched RI values and characteristic fragments with the standards on the Rtx‐5MS and Rtx‐Wax columns (Table , Figure ). These volatiles included 13 alcohols, 10 aldehydes, 3 esters, 1 monoterpene, 2 monoterpene oxides, 2 ketones and 1 organic acid.…”

Resin adsorption and naringinase treatment represent two major methods for debittering naringin in citrus juices, but their effects on the aroma profiles of citrus juices have not been intensively investigated yet. In this study, the volatiles of the fresh, naringinase‐treated and resin‐absorbed juices of pummelo were investigated by gas chromatography coupled with a mass spectrometer (GC‐MS) and sensory evaluation. The fresh juice was analyzed to have 24 volatiles, among which (E)‐3‐hexen‐1‐ol and 1‐hexanol had the highest concentrations. After the naringinase treatment, the juice showed 32 volatiles, among which (Z)‐ and (E)‐linalool oxides were the most dominant in concentration; while the resin adsorption captured most of the volatiles. Principal component analysis (PCA) showed that naringinase treatment led to an increase in some compounds, particularly aldehydes, whereas resin adsorption decreased the amounts of a lot of volatile compounds. The sensory evaluation demonstrated the fresh and naringinase‐treated juices had similar aroma profiles, whereas the resin‐adsorbed juice had a much weaker aroma intensity than its counterparts. These results indicated that the naringinase treatment is more desirable than the resin adsorption for debittering citrus juice because the naringinase treatment could maintain the aroma profile close to the original, fresh juice.

“…That is why it is difficult to achieve a sum close to 100% for all examined components. In the case of overlapping results, the sum of the components can be much higher than 100% (Fengel and Wegener 1989;Prosiński 1984).…”

“…The proportions of particular components in wood tissue depend on the species, the habitat conditions, the climate, the part of the tree from which samples are taken (trunk, branches, roots, sapwood or heartwood, bark, juvenile, or mature wood), the time of year, and the health of the tree (Bikovens et al 2013;Miranda et al 2017;Szczepkowski et al 2007;Zobel and Sprague 1998). Another factor for the variation of the chemical structure of wood and its possible uses is the age of the tree, as has been documented for certain species (Berrocal et al 2004;Fidelis et al 2013;Healey et al 2016;Miranda and Pereira 2002;Rencoret et al 2011;Uprichard and Lloyd 1980). However, these studies have not included the silver birch (Betula pendula Roth.…”

“…The ethanol-benzene mixture gives the highest level of wood extractives, but because of the high toxicity of benzene, other solvents like acetone and ethanol are commonly used. Substances soluble in cold and hot water include mineral salts, sugars, tannins, dyes, pectins, free acids, and others (Fengel and Wegener 1989;Han and Rowell 1997;Prosiński 1984).…”

The effect of tree age on the chemical composition of the wood of silver birch (Betula pendula Roth.) in Poland

The article presents the results of a so far most extensive study on the effect of tree age on variation of the chemical structure of silver birch wood carried out in Poland. Field studies took place in 12 forestry districts distributed throughout the country. In each district, study sites were selected with stands aged approximately 30, 50, and 70 years in fresh broadleaved forest habitats, as well as in five districts in fresh mixed broadleaved forest habitats. Analyses were made of the contents of substances soluble in cold and hot water, ethanol and 1% NaOH, as well as the contents of cellulose, lignin, pentosans and ash, and the pH, of wood from 306 silver birch trees. Tree age was shown to have a significant effect on the contents of cellulose, pentosans, ash, and substances soluble in 1% NaOH. In the case of the other characteristics, age was found to have no significant effect. The cellulose content was lowest in 30-year-old stands and increased with tree age. Similar observations were made regarding ash content. Contents of pentosans and substances soluble in 1% NaOH were highest in the wood of the youngest trees. Since birch wood is used by the pulp and paper, board and energy industries, the knowledge of its chemical composition, depending on the age of the trees, can be of potential practical importance for its further application.

“…Accordingly, there is a need for studies that explore the methods to be used for viable management of harvesting rotations, the means by which harvesting occurs, and the nutritional requirements of trees during the period of biomass regrowth. Currently, harvesting occurs via removal of 100% of the crown [15][16][17], or of the entire tree, after cutting the trunk 50 cm above the soil [10,17], and then extracting the essential oil from all parts of the tree [18][19][20][21]. Clearly, at the moment of harvest, all nutrients assimilated from the soil by the plant are lost to future biogeochemical cycles at the growth site [22][23][24][25], leading to an export of nutrients that can compromise ecosystem productivity during future crop rotations [26][27][28].…”

Rosewood (Aniba rosaeodora Ducke) is an endangered tree that produces essential oil of high commercial value. However, technical-scientific knowledge about cultivation is scarce and studies are needed to examine the management viability. The current study evaluated rosewood aboveground biomass management, measuring the export of nutrients resulting from harvesting and testing sustainable management models. The crown of 36 rosewood trees were pruned and 108 trees cut at 50 cm above the soil in two regions in Central Amazonia. Post-harvest performance of sprouting shoots was evaluated and after, sprouting shoots were pruned so that the development of two, three and all shoots was permitted. Nutrient stock estimation was calculated as the product of mass and nutrient concentration, which allowed nutritional replacement to be estimated. The pruning facilitates regrowth by 40.11% of the initial mass while by cut regrow 1.45%. Chemical attributes of regrowth biomass differed significantly prior to management and regrowth had a significant correlation with the reserves in root tissues and with the pre -management status of the individual tree. Driving sprouts resulted in significantly larger growth increments and may provide a form of management that can viably be adopted. Biomass sequential management resulted in high nutrient exports and the amount of fertilizer needed for replenishment depended on the intensity and frequency of cropping. Compared with the cut of the tree, pruning the canopy reduces fertilizers that are required to replenish amount by 44%, decreasing to 26.37% in the second rotation. The generated knowledge contributes to this silvicultural practice as it becomes ecologically and economically viable.
