HIGHLIGHTS The influence of modified atmospheric packaging and storage conditions including, temperature, and relative humidity on shelf-life and quality of tomatoes of natural farming and chemical farming is compared. Zero energy cool chamber was optimized for extending the shelf-life of tomatoes Tukey’s HSD was used for significant mean separation of quality parameters and CRD and RBD designs were used for analyzing quality attributes during storage. This paper investigated and presented a comparison of quality parameters of SPNF and CHEM tomatoes as well as changes during storage. Abstract A study was conducted to record the effect of modified atmospheric packaging (MAP), storage conditions (ambient, zero energy cool chamber and refrigerated) as well as storage period on shelf-life and quality of tomatoes produced through Subhash Palekar natural farming (SPNF) and chemical farming (CHEM) systems. Freshly harvested tomatoes (SPNF and CHEM) packed in LDPE pouches (25.40 μm and 10 pin holes/100 cm2 area) and without packaging were stored under ambient (27±2 °C and 70±2% RH), zero energy cool chamber (ZECC) (17±2 °C and 82 ±2 % RH) and low temperature conditions (10±2 ºC and 90 % RH) for shelf-life studies. The shelf-life comparison was done at every two days’ interval up to 24 days based on physiological loss in weight (PLW) and spoilage percentage. SPNF and CHEM tomatoes were compared on the basis of quality attributes (firmness, acidity, TSS, sugars, total phenols, antioxidant activity etc.), mineral content and sensory characteristics. Results revealed that tomato stored in refrigerated condition had significantly (p ˂0.05) lowest PLW and spoilage incidence and highest sensory acceptability up to 24 days and was at par with ZECC stored tomatoes. Quality evaluation indicated that tomatoes grown under SPNF system contained a higher amount of total solids, total sugars, reducing sugars, ascorbic acid, total phenols and ash. The results showed that tomatoes with MAP and stored under refrigerated storage condition retained maximum quality up to 24 days followed by tomatoes stored under ZECC (18 days) compared to 12 days at ambient conditions.

: Soybean is the main oilseed crop in the world, and one of the main challenges for its production is the Anticarsia gemmatalis management, especially in agroecological production systems. In this study, it was analyzed the impact of dynamized solutions applied to soybean plants and pro-vided as food to A. gemmatalis on insect biology. Solutions tested include: Calcarea carbonica 4CH, Carbo vegetabilis 12CH, Staphysagria 4CH, A. gemmatalis nosode 12CH, Soybean nosode 4CH, and control of distilled water. Biological characteristics analyzed include: weight of caterpillars at the beginning and end of the 4 th instar, dry weight of pupa, caterpillar length at 4 th instar, duration of cycle, emergence of adults, fecundity of females, and ingestion, ingested food conversion efficiency, and efficiency of digested food conversion. At the beginning and at the end of the 4 th instar, caterpillars fed soybean leaves treated with homeopathic substances showed reduced body weight relative to the distilled water control. The dynamized solutions tested are promising as an efficient alternative method for the control of A. gemmatalis , promoting lower conversion of food into biological efficiency and biomass.

: In addition to destroying the leaves, stems, pods, and grains of soybean ( Glycine max ), Spodoptera frugiperda larvae may also have the cut off behavior in the seedlings close to the ground, harming the establishment of the soybean crop. Therefore, this study aimed to evaluate the consequences of the fall armyworm attack by adopting the cut off behavior, which has been similarly documented for black cutworm ( Agrotis ipsilon ) in newly emerged soybean plants. The treatments were five levels of infestation with 0, 5, 10, 20 and 40 larvae per m 2 . Three variables were assessed: (1) stand (relationship between attacked and initial number of plants), (2) types and amounts of injured structures, such as hypocotyl (embryonic shoot), and the cotyledons (seed leaves), and (3) level of defoliation. The variables were collected every 24 hours until the pupal stage. Additionally, the final stand of the seedlings was quantified, with the highest injury intensity observed in the plots that contained the highest number of larvae.

HIGHLIGHTS Hydroxytyrosol (HT)-loaded PCL nanocapsules were appropriately obtained and characterized. A simple and fast UHPLC method for HT determination in PLC nanocapsules was developed and validated. High HT encapsulation efficiency was achieved into the PCL nanocapsule formulations. HT-loaded PCL nanocapsules showed physicochemical stability from 30 to 90 days. Abstract Hydroxytyrosol (HT) is a natural phenolic compound found in leaves of olive trees. It is a photosensitive solid phytochemical constituent and an irritant substance to skin and mucosa as pure drug. HT is a lipophilic chemical constituent and shows low solubility in water, bitter taste, and instability to oxidizing atmosphere. Considering the limitations for its suitable therapeutic use, the aim of the present study was to obtain, to characterize, to quantify, and to evaluate the stability of HT-loaded poly(ԑ-caprolactone) nanocapsules for its further use in pharmaceutical and nutraceutical products. Nanocapsules were prepared by method of interfacial deposition of the preformed polymer. The formulations were characterized by morphological and spectroscopic methods. The UHPLC-PDA analytical method was developed and validated for quantifying the HT encapsulation. Physicochemical stability assay was performed for 120 days. Nanocapsules were successfully obtained by the proposed method. The morphological evaluation demonstrated the drug absence in the nanocapsule surface. Fourier-transform infrared spectroscopy demonstrated the drug nanoencapsulation. The analytical method was validated and confirmed a high HT encapsulation efficiency over 95%. Considering the physicochemical stability testing, the polydispersity index changed after 30 days for NC-2 (HT at 2 mg/mL) and after 90 days for NC-5 (HT at 5 mg/mL). Zeta potential changed after 60 days for both formulations (NC-2 and NC-5). pH values were modified after 60 days for NC-5 and after 90 days for NC-2. HT-loaded PCL nanocapsules demonstrate adequate physicochemical features and high drug encapsulation. The different formulations revealed stability changes from 30 to 90 days. Additional in vitro and in vivo evaluations may be performed in order to use these nanoformulations for treating several diseases based on oxidative-inflammatory environments.

: Probiotics are live microorganisms that when ingested in adequate amounts help in the balance of the intestinal microbiota. Kefir is considered a probiotic beverage associated with the improvement of several pathologies. Fruit juices are considered an excellent culture medium for these microorganisms, presenting nutrients that favor microbial growth. This work aimed to prepare a probiotic drink from the fermentation of whole grape juice by microorganisms from the water kefir. Different amounts of kefir grains were tested (5, 10, 20, 30, 40, 50, and 60 g) in 500 mL of grape juice. The fermentation processes were developed under static conditions at room temperature for 24 h. Seven formulations were tested for physical-chemical and microbiological analyses. A questionnaire on the knowledge and consumption of probiotics was applied to the academic community. Three formulations were selected for sensory analysis and stored under refrigeration. All formulations showed growth of lactic acid bacteria and no reduction in storage viability. A significant reduction in soluble solids was observed in all formulations, and an increase in acidity and pH formulations with 5 and 20 g of kefir, respectively. About 64% of the participants reported knowing the definition of probiotics. In addition, a low intake of this product was observed. The formulation with 5 grams of water kefir grains was better accepted by the consumers when compared to the others. Thus, grape juice can be a great alternative to consume probiotic microorganisms, especially for those who do not consume dairy products.
