Flavor is an important quality of mature tomato fruits. Compared with heirloom tomatoes, modern commercial tomato cultivars are considerably less flavorful. This study aimed to compare the flavor of 71 tomato accessions (8 pink cherry, PC; 11 red cherry, RC; 15 pink large-fruited, PL; and 37 red large-fruited, RL) using hedonism scores and odor activity values. Taste compounds were detected using high-performance liquid chromatography. Volatiles were detected using gas chromatography–olfactometry–mass spectrometry. The flavor of tomato accessions can be evaluated using the DTOPSIS analysis method. According to the results of DTOPSIS analysis, 71 tomato accessions can be divided into 4 classes. Tomato accessions PL11, PC4, PC2, PC8, RL35, RC6, and RC10 had better flavor; accessions PC4, PC8, RC10, RL2, and RL35 had better tomato taste; and accessions PL11, PC2, and RC6 had better tomato odor. The concentrations of total soluble solids, fructose, glucose, and citric acid were shown to positively contribute to tomato taste. Tomato odor was mainly derived from 15 volatiles, namely, 1-hexanol, (Z)-3-hexen-1-ol, hexanal, (E)-2-hexenal, (E)-2-heptenal, (E)-2-octenal, (E,E)-2,4-decadienal, (Z)-3,7-dimethyl-2,6-octadieal, 2,6,6-timethyl-1-cyclohexene-1-carboxaldehyde, (2E)-3-(3-pentyl-2-oxiranyl)acrylaldehyde, 6-methyl-5-hepten-2-one, (E)-6,10-dimetyl-5,9-undecadien-2-one, methyl salicylate, 4-allyl-2-methoxyphenol, and 2-isobutylthiazole. Significant positive correlations (P < 0.05) were detected between the compound concentrations and flavor scores. The above-mentioned compounds can be used as parameters for the evaluation of flavor characteristics and as potential targets to improve the flavor quality of tomato varieties.

ABSTRACT Garlic is a vegetable rich in starch and in aromatic substances; it has high value as a spice and is consumed as a fresh vegetable or in processed products. The garlic market demand has been growing in the last years, and virus-free garlic seed is a technology that can result in better quality products. The objective of this work was to evaluate the quality of virus-free garlic cultivars (VFGC) grown under high altitude conditions in the Semiarid region of the Northeast of Brazil. Three experiments were conducted in 2018 in Portalegre, state of Rio Grande do Norte, Brazil: the first experiment with first-generation VFGC (G1), the second with second-generation VFGC (G2), and the third with infected cultivars (without clonal cleaning). The experiments were conducted in randomized block experimental design, with four replications. The treatments consisted of five garlic cultivars (Amarante, Branco-Mossoró, Cateto-Roxo, Gravatá, and Hozan). The use of virus-free garlic seeds results in bulbs with larger diameter and higher soluble solid and total solid contents, pungency, and industrial yield, showing that the seed health is important for the quality of garlics for fresh consumption and industrial processing. The cultivars Amarante, Cateto -Roxo, and Hozan had the highest total solid contents; and the cultivar Hozan had the largest bulb diameter and the highest soluble solid contents, pungency, and industrial index. The cultivar Hozan is the most indicated for dehydration due to its higher industrial index. Bulb diameter, pungency, and industrial index presented positive correlations with soluble solids, pungency, and industrial index.

In this study, a simple, sensitive and reliable fingerprint analysis method by high-performance liquid chromatography coupled with diode array detection (HPLC-DAD) was developed for quality analysis of Bulbus Lilii, which is a famous traditional Chinese medicine and widely used as a restorative food. Then the developed method was subsequently applied to analyse 16 samples collected or purchased from different origins. Twelve common fingerprint peaks, including four definitely identified peaks, were found in total, and were involved for further characterisation and quality evaluation of Bulbus Lilii. The chemical quality of commercial samples collected from different origins varied obviously, indicating that more attention should be paid to the standardisation of the process of harvesting, manufacturing and storage of Bulbus Lilii. This is the first time that a new method has been established to control the quality of Bulbus Lilii through HPLC-DAD.

ABSTRACT The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this study was to evaluate the effect of different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity and quality. Quantitative and qualitative fruit production parameters of plants visited by Apis mellifera L., manually self- and cross-pollinated plants and plants without pollination were analyzed and compared. Fruit production was high for all treatments and all fruits presented four seeds per fruit, on average, confirming that this grape cultivar is autogamous. However, fruit set after spontaneous self-pollination was statistically lower than that of all other treatments, and pollination by A. mellifera showed the highest fruit production. Furthermore, pollination by honey bees resulted in increased biomass, reflected on fruit weight, but the content of soluble solids remained unchanged. The results of this study showed that there is no need of pollinators for fruit production of ‘Bordô’ cv., but the presence of these agents, in particular Apis mellifera, influences commercially important quality parameters such as fruit yield and fresh weight. Therefore, the use of bee hives in areas with deficit of pollinating insects may promote an improvement in yield and quality of this cultivar.

Insamyangpye–tang (ISYPT) is a traditional medicinal formula comprised of 13 herbs and has been used in East Asia to treat lung-related diseases. However, to our knowledge, no method of analysis for its quality control has been reported. In this study, a method of analysis for quality control of ISYPT was developed using high-performance liquid chromatography. Chromatographic separation, analysis, and assay verification were performed with a distilled water–acetonitrile mobile phase system, both containing 0.1% (v/v) trifluoroacetic acid, and a Gemini C18 analytical column (4.6 mm × 250 mm, 5 mm) using authentic standards for eight marker compounds. These marker constituents were detected simultaneously at 0.09–5.95 mg/g. The analysis method developed can be used for basic quality control of ISYPT.

Abstract Background: Flavor is an important quality of tomato fruit. The improvement of flavor attracts more and more attention. This study aimed to explore the differences in the concentrations of nutrients and volatiles between red and pink colors of tomatoes fruit, including cherry tomato (S. lycopersicum var. cerasiforme Mill) and large-fruited tomato (S. lycopersicum), respectively. Methods: Soluble sugar, titratable acids, and volatile organic compounds, were detected using gas chromatography-mass spectrometry. Hedonism score and odor activity value were used to evaluate the taste and odor intensity of tomato fruit. The membership function method was used to comprehensively evaluate the fruit flavor. Results: It was found that the levels of aldehydes, ketones, esters, and phenols were significantly higher in pink tomato than in red tomato. The concentrations of ascorbic acid, soluble solids, fructose, glucose, citric acid, and carotenoid-derived volatiles were significantly greater in cherry tomato than in large-fruited tomato. However, Phe-derived and Ile/Leu-derived volatiles were significantly higher in pink large-fruited tomato and red cherry tomato. The fatty and irritant odors were stronger in pink tomato than in red tomato, and cherry tomato had better overall taste than large-fruited tomato. The sweetness and sweetness/acidity ratio were significantly higher in pink cherry tomato than other categories of tomatoes. Conclusion: The concentrations of volatiles varied greatly between pink and red tomatoes, and the levels of nutrients varied greatly between cherry and large-fruited tomatoes. This study can provide reference for tomato flavor quality improvement breeding.

RESUMO - Objetivou-se avaliar a produção quantitativa e qualitativa dos açúcares produzidos no caldo de sorgo sacarino, em duas épocas de corte. Utilizou-se o delineamento em blocos casualizados com 6 repetições, em parcelas subdivididas no tempo, avaliando três cultivares de sorgo sacarino (BD 5404, BRS 511 e BD1615). Ao final de cada ciclo, foram avaliados produtividade de colmos, taxa de extração, teor de sólidos solúveis (ºBrix) e os açúcares totais (sacarose, glicose e frutose) presentes no caldo, sendo estes quantificados em cromatografia líquida de alta precisão (HPLC). Verificou-se que as cultivares apresentaram a maior produtividade de colmos na safra em comparação com a rebrota, sendo 64,50 e 9,23 t ha-1, respectivamente. A taxa de extração do caldo foi menor na rebrota. O teor de açúcares totais presente no caldo não diferiu entre as duas safras, apresentando média de 94 g L-1. O ºBrix diferiu tanto entre as cultivares como entre as safras. Apenas a cultivar BRS 511 apresentou a mesma proporção de açúcares presentes no caldo, nas duas safras, com maior teor de sacarose produzido. Conclui-se que as condições climáticas afetam os caracteres agronômicos e industriais do sorgo sacarino. A cultivar BRS 511 apresentou o melhor desempenho agronômico e industrial visando à produção de etanol. A quantidade de açúcares produzidos não variou em função do ciclo, mas a qualidade dos açúcares (sacarose, glicose e frutose) variou de acordo com a cultivar.Palavras-chave: Sorghum bicolor, produtividade, açúcares fermentescíveis, HPLC. SUGARS PRODUCTION IN SWEET SORGHUM BROTH IN TWO CUTTING TIMES  ABSTRACT - The objective of this study was to evaluate the quantitative and qualitative production of sugars in sorghum broth at two cutting times. A randomized complete block design with six replications was used in plot subdivided in time evaluating three cultivars of sorghum saccharine (BD 5404, BRS 511 and BD1615). At the end of each cycle, shoot yield, extraction rate, soluble solids content (ºBrix) and total sugars (sucrose, glucose and fructose) present in the broth were evaluated, and these were quantified by high performance liquid chromatography (HPLC). Cultivars showed higher productivity of shoots in the crop compared to regrowth, with 64.50 and 9.23 t ha-1, respectively. The broth extraction rate was lower at regrowth. The total sugars content in the broth did not differ between the two harvests, with an average of 94 g L-1. Brix differed between cultivars and between crop seasons. Only the cultivar BRS 511 presented the same proportion of sugars in the broth, in the two harvests, with higher content of sucrose. As conclusion, the climatic conditions affected the agronomic and industrial characteristics of sorghum saccharine; the cultivar BRS 511 presented the best agronomic and industrial performance regarding ethanol production; the amount of sugars produced did not change with the different cycles and the quality of sugars (sucrose, glucose and fructose) varied among cultivars.Keywords: Sorghum bicolor, productivity, fermentable sugars, HPLC.

The purpose of this study was to assess yield and quality of tomato (Lycopersicon esculentum Mill.) in response to drip (DI) and sprinkle irrigation (SI) in southwestern Ontario. Three irrigation treatments, DI, SI and no irrigation (NI) and five tomato cultivars, FM6203, H2653, H722, OH7814 and PUR812, grown on a Fox sandy loam soil, were evaluated during four growing seasons between 1986 and 1989. Both DI and SI increased the marketable tomato yield in 3 of 4 yr. In general, DI resulted in higher tomato yields than SI, but this was only statistically significant in 1 yr. Sprinkle irrigation out performed drip irrigation in one hot, dry year in 1988. Throughout the 4 yr, OH7814 was consistently high yielding, H2653 was consistently low yielding and FM6203, H722 and PUR812 performed more consistently than the other cultivars. In wet years, yield differences due to cultivar treatments were greater than those due to irrigation treatments, while in dry years, yield differences due to both irrigation and cultivar treatments were highly significant. Soluble solids and total solids were decreased by DI and SI. The DI produced the most uniform soil moisture regime, followed by SI. The NI plots had the greatest degree of water stress, as indicated by the low soil water potential, low stomatal conductance and elevated crop canopy temperature. Key words:Lycopersicon esculentum, yield, soil water potential

The aim of the study was to analyze phenolic acids in Lithuanian propolis and to compare it with the composition of propolis in neighboring countries (Latvia and Poland) according to the predominant flora in the collecting places. The study was also aimed at the evaluation of the effect of the layer thickness (mm) of the harvested propolis on the quality of the raw material in determining the amount of phenolic acids. Materials and methods. The object of the study was propolis collected in Lithuania, Poland, and Latvia in late July of 2006 and 2007. The qualitative and quantitative analysis of phenolic acids was performed using the high-performance liquid chromatography technique (HPLC). Results. The results of the study showed that the quantitative and qualitative composition of phenolic acids in propolis depended on the plants from which the bees in the area collected substances for the raw material of propolis. The predominant phenolic acids were determined to be ferulic and coumaric acids, and they may be among the main indicators of quality in the standardization of the raw material and preparations of propolis. Conclusion. We created an HPLC-based analysis method for the identification and quantification of phenolic acids in propolis. The variety of phenolic acids in propolis depends on the vegetation predominating in the harvesting area. Studies have shown that the highest amount of phenolic acids is observed in propolis harvested in areas characterized by the predominance of deciduous trees and meadows. Results have also shown that ferulic and coumaric acids are the predominant phenolic acids in propolis. The thickness of the layer of the collected propolis in the hive also influences its chemical composition.

Abstract Background: The appearance of synthetic indigo has caused most people to forget the past brilliance of natural indigo. However, in parts of southern China, the folk still use and trade in natural indigo paste. The aims of this study were to i) document the traditional knowledge and experience of how people identify the quality of indigo paste and ii) explore the rationality of the quality judgment index used by local people.Method: We interviewed 283 traditional indigo paste artisans in 3 markets and 15 villages in Guizhou, Yunnan, and Fujian Provinces. Frequency of citation (FC), Mention index (QI), and Fidelity level (FL) of each indigo paste quality judgment index were calculated to determine the most commonly used, most recognized, and most important quality judgment index. A quantitative study was conducted on 21 indigo paste samples of different quality grades using high-performance liquid chromatography with diode-array detection (HPLC-DAD), an acidity meter, and particle size analyzer. The relationship between the content of the effective components, pH, and particle size of the indigo paste and quality was explored. Results: The people divided indigo paste into five quality grades i.e., best, good, general, poor, and worst. Four main quality judgment indices were color, taste, touch, and dyeing ability. Among all study areas, color was the most commonly used, most important, and most recognized index. Effective ingredient content and pH differed significantly with different quality graded indigo pastes, but there was no significance difference between particle size and quality. In addition to indigo, indirubin played an important role in identifying the quality of indigo paste.Conclusion: Our study confirmed that the quality of indigo paste could be evaluated using the four indices (color, taste, touch, and dyeing ability). The people used indigo and indirubin content together to determine the quality of the indigo paste, while synthetic indigo is determined by indigo content only. The simple knowledge and experience of traditional folk has guiding significance for the modern development of indigo paste production.
