The development of organic farming as a result of increasing consumer preference for organic food has led to the development and registration of new pest-control products for certified organic production. In this study, the effects of three biocontrol products containing spores and mycelium of Arthrobotrys oligospora—Artis®, Beauveria bassiana—Bora®, and Coniothyrium minitans—Öko-ni® were tested on four basil (Ocimum basilicum L.) cultivars: ‘Aromat de Buzau’, ‘Serafim’, ‘Macedon’ and ‘Cuisoare’. The application of Öko-ni® increased basil yields by 8% relative to Control. The application of Bora® increased chlorophyll content of basil leaves by 2% and the activity of photosynthesis by 66% relative to the Control. Basil essential oil (EO) content was increased by 18% with the application of Artis® and by 34% with the application of Bora® and Öko-ni®, respectively. The content of phenolic compounds analyzed by HPLC varied; caffeic acid concentration was higher in the plants treated with Öko-ni®, hyperoside, isoquercitrin and rutin concentrations were higher in those treated with Artis®, while the quercitrin content was higher in Bora®-treated plants. The two main EO constituents that were identified were linalool and methyl chavicol in ‘Aromat de Buzau’, linalool and eugenol in ‘Serafim’, neral and geranial in ‘Macedon’, also linalool and eugenol in ‘Cuisoare’. The investigated myco-biocontrol products had positive effects on basil fresh biomass and EO content and also influenced the content of phenolic compounds.

The nutritional and sensory value of Chinese radish, cv. Jarola F1, grown in organic and conventional systems was evaluated. The experiments were based on certified organic land and conventional land of the Czech University of Life Sciences Prague at the experimental station of Troja. Radish was grown in two spacings. Radish from the organic cultivation system exhibited a significantly lower dry matter content compared to the conventional production, 62.4 g/kg <br /> and 68.9 g/kg, respectively. This can be explained by growing under unwoven textile. Furthermore, radish cultivated organically had a significantly lower content of monosaccharides (17.2 mg/kg, while the conventional production contained 26.1 mg/kg) and significantly higher contents of nitrates. The content of vitamin C in organic production tended to be higher (212 mg/kg, in conventional production 169 mg/kg). The crude fibre content or the content of minerals was not significantly affected by the growing system. Growing spacing did not affect the nutritional value. Organically produced radish had better sensorial evaluation. &nbsp;

The demand for organic food is rising since consumers want food from reliable, highest quality sources originating from the environment, undisturbed by cultivation and processing. It is necessary to determine to what extent there is a scientific basis for the claims that organic food is of high quality. In this study, beetroot from an organic production system originating from 6 certified organic food producers from different geographic locations was examined. The organic beetroot samples were processed by pasteurization at 700 C and 900 C into beet juice or by drying at 550 C. The following samples were tested and compared: fresh beetroot, pasteurized beet juice and dried beetroot slices. The concentration of vitamin C, level of total phenol compounds (TPC) and antioxidative activity (TAA) in beetroot were influenced by the geographic origin and the applied processing method. The highest degradation for all analysed parameters was found in the samples treated by drying or pasteurisation at 90ºC. The lowest losses of studied phytochemical components were observed during juice pasteurisation at 700C. The correlation coefficient between TPC and TAA was high and significant (r2 = 0.966).

Roselle (Hibiscus sabdariffa L.), as an edible flower, has long provided an array of positive effects on human health. This benefit is a result of phenolic compounds that are naturally present mainly in the calyx. Plentiful medicinal remedies and functional foods based on this flower are available worldwide, as supported by the studies of phenolic compounds in recent decades. This paper aims to provide a comprehensive review of the composition, biological activity, and beneficial effects on human health of phenolic compounds in roselle. This review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A structured search in the published literature for phenolics compositions in roselle was required prior to the evaluation on the validity of the reported analytical methods. Reliable identification and quantification of phenolic compounds in roselle can be achieved by employing the proper extraction and separation methods. With ample alternative analytical methods discussed here, this review provided an aid for comprehending and selecting the most appropriate method for a particular study. The applications of the analytical methods highlighted indicated that phenolic acids, flavonoids, and their derivatives have been identified and quantified in roselle with a range of biological activities and beneficial effects on human health. It was also disclosed that the composition and concentration of phenolic compounds in roselle vary due to the growth factors, cultivars, and environmental influence. Finally, apart from the research progress carried out with roselle during the last ten years, this review also proposed relevant future works.

Abstract Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative paths toward sustainability in agricultural production. Argentina is ranked second in the world in terms of land under organic certification. Extensive sheep production in Patagonia natural grasslands accounts for most of this area and harvested organic area remains a very small fraction of total harvested land (0.6%). This paper aims to contribute to the discussion of opportunities and limitations in organic farming as an ecological intensification alternative for Argentina's Pampas. A case study was conducted on Pampa Orgánica Norte. This is a group of nine organic farmers that manages field crops and livestock-certified organic production. Farmers interviewed in this study considered different criteria including economic and environmental attributes when choosing to produce organically. However, the main drivers for conversion to organic production are related to environmental factors, in particular ecosystem protection. The main limitations in organic production are related to crop management practices, primarily weed control. To achieve the goal of increasing organic production a more active role of the public sector in technology generation and transfer was demanded by farmers.

AbstractTea, from the old ages to the day, is widely consumed both for enjoyment and health care due to its positive effects. The consumption of these products is increasing day by day as a result of the clear presentation of the fact that tea contains high amount of antioxidant substances (such as phenolic compounds), which is important in prevention and treatment of diseases. Tea beverage is a very important source of polyphenols. In this study, phenolic content and antioxidant capacity of different tea species were calculated by modeling with experimental design method. In the experimental part, polyphenol content was determined using the Folin-Ciocalteu method. The total amount of phenolic substance content was examined by Box-Behnken design and response surface method on black tea, green tea and white tea on different extraction temperature, extraction time and solid / liquid ratio. Solid / liquid ratio was found to be the most important parameter in terms of polyphenol content extraction from different tea samples. The highest polyphenol amount (411.762 mg gallic acid / mL) was found in green tea. To the best of our knowledge, this is the first data presenting comparatively study the effect of extraction condition on amounts of phenolic compounds from different tea samples.

Altering the growing temperature during controlled-environment production not only influences crop growth and development, but can also influence volatile organic compound (VOC) production and, subsequently, sensory attributes of culinary herbs. Therefore, the objectives of this study were to (1) quantify the influence of mean daily temperature (MDT) and daily light integral (DLI) on key basil phenylpropanoid and terpenoid concentrations, (2) determine if differences in sensory characteristics due to MDT and DLI influence consumer preference, and (3) identify the sweet basil attributes consumers prefer. Thus, 2-week-old sweet basil ‘Nufar’ seedlings were transplanted into deep-flow hydroponic systems in greenhouses with target MDTs of 23, 26, 29, 32, or 35 °C and DLIs of 7, 9, or 12 mol·m−2·d−1. After three weeks, the two most recently mature leaves were harvested for gas chromatography–mass spectrometry (GC–MS) and consumer sensory analysis. Panel evaluations were conducted through a sliding door with samples served individually while panelists answered Likert scale and open-ended quality attribute and sensory questions. The DLI did not influence VOC concentrations. Increasing MDT from 23 to 36 °C during production increased 1,8 cineole, eugenol, and methyl chavicol concentrations linearly and did not affect linalool concentration. The increases in phenylpropanoid (eugenol and methyl chavicol) were greater than increases in terpenoid (1,8 cineole) concentrations. However, these increases did not impact overall consumer or flavor preference. The MDT during basil production influenced appearance, texture, and color preference of panelists. Taken together, MDT during production influenced both VOC concentrations and textural and visual attribute preference of basil but did not influence overall consumer preference. Therefore, changing the MDT during production can be used to alter plant growth and development without significantly affecting consumer preference.

Abstract Background Negative energy balance during the transition period is a concern for both conventional and certified organic dairy systems. During early lactation, supplemental strategies are used to cope with nutrient deficiencies that are associated with impaired health, production, and reproduction. As organic certified dairies in the United States face restricted access to dietary supplements, the evaluation of products especially formulated for organic production is needed. Our objective was to assess the effect of supplementing 0.45 kg/d of an organic rumen-protected fat (RPF) on health, metabolic status, and productive and reproductive performance of organic certified Holstein cows from 1 to 150 days in milk (DIM). Two-hundred and two cows were enrolled in a randomized blocked controlled trial conducted from January to July, 2017 in a certified organic dairy located in Northern Colorado (USA). Two groups were randomly assigned to be individually supplemented with organic RPF (ORG; n = 100) or control pellets (CON; n = 102) once per day, in addition to the total mixed ration (TMR). Outcomes of interest included disease occurrence, culling, mortality, serum concentration of glucose and non-esterified fatty acids (NEFA), milk yield (kg/d) and milk components, resumption of cyclicity, time-to-first artificial insemination (AI), conception at first AI, and conception within 150 DIM. Results A significant effect for the inclusion of RPF was found in daily milk yield; RPF supplemented cows had greater milk yield (1.6 kg/d) compared to CON cows up to 150 DIM (P = 0.03). During grazing, multiparous (MP) ORG cows had greater milk yield compared to MP CON cows, whereas no effect was found in primiparous (PP) cows. Health outcomes, serum metabolite concentrations, and reproductive performance were not affected by the inclusion of RPF. Body condition loss was smaller in the ORG group up to 80 DIM; however, there was no effect on body condition during the grazing season and in the overall study period. Conclusions These results indicate that supplementation of RPF increased daily milk yield and prevented body condition loss during transition. However, RPF supplementation did not affect health, serum metabolite concentration, milk components, and reproductive outcomes.
