The effectiveness of using some biological organisms as biological catalysts to reduce the incidence of melon disease in greenhouse conditions.
To address the problem of melon yield and loss of fruit quality due to manna infestation, five biofilters, Trichoderma viride, Trichoderma harzianum, Bacillus megaterium, Bacillus subtilis and Pseudomonas fluorescens, were tested in combination with the fungicide Ridomil gold plus.5. Laboratory results show that the use of biofilters, in addition to the recommended fungicide, reduces the germination of fungi. The results of the greenhouse show a reduction in the severity of the disease compared to controls.
Quality canning in banana fruits, packed in a pine needle and paper to capture ethylene gas based on haloazite during storage.
Newly developed ethylene cleaning paper based on pine needle waste was evaluated for banana storage. The material includes halositic nanotube (HNT) nanomaterial and microfibrillated cellulose (MFC). Ultimately, the color, TSS, and pH of the banana remained stable during the ten-day storage period, and 30% PN / MFC / HNT-based packaging has been shown to slow the ripening and aging of bananas.
Dry matter content of mangoes at harvest to achieve high consumer quality of different varieties in different growing seasons.
The Palmer and Tommy Atkins mangoes were selected to assess the relationship between dry matter content (DMC) and soluble solids content (SSC), with consumer acceptance for different seasons and varieties. Estimated fruits show a sharp increase in DMC in summer and winter. Based on the analysis of the DMC Vis-NIR spectrometer at harvest, which varies between 50-80 g per kilogram, mangoes are grouped into three categories for both varieties and seasons. They are then stored under transport conditions at 12 o C and 90-95% RH until ripe. Analyzes of physicochemical and sensory parameters show that higher DMCs at harvest produce higher SSCs at maturity. The study showed only a slight effect of variety and season on the minimum DMC needed to achieve consumer acceptance.
Characteristics of gas exchange and fluorescence of chlorophyll of hyoscyamus muticus L. in different phenological stages in extreme dry environmental conditions, southwestern desert, Egypt
A new oxygen uptake system using natural latex rubber (NRL) with a photocatalytic system composed of acetophenone and manganese chloride has been developed and tested to remove oxygen from oxidation-sensitive food packaging. The rheology, particle size of 399.6 nm and zeta value of -23.30 mV indicate that the stability and viscosity of NRL / PCS are suitable for coating applications. Colorimetry and FTIRS performed before and after oxygen uptake also showed that the NRL / PCs system is a sustainable substitute for iron-based food oxygen uptake.
Vacuum packaging and ascorbic acid synergistically maintain the quality and taste of freshly sliced potatoes.
A study evaluated the effect of storing freshly sliced potatoes in a vacuum package (VP) and dipping in 5 g of L ascorbic acid (ASA) on the overall quality of vegetables. The treatment reduces darkening, weight loss and loss of firmness by reducing ethylene generation and respiration levels. It inhibits the accumulation of malonic dialdehyde, reactive oxygen species and phenols. It has also been found to slow the increase in glucose, sucrose and fructose.
The treatment successfully preserves the taste and aroma of sliced potatoes by inhibiting aldehydes due to the breakdown of lipids responsible for rancid unpleasant tastes.
Dynamics of etiolation observed by seedling morphology, carotenoid composition, antioxidant level and protochlorophyll photoactivity in Arabidopsis thaliana.
Because etiolated Arabidopsis thaliana seedlings are used to study the deethiolation process, the dynamics of molecular etiology of wild and lutein-deficient (lut2) mutants were studied, between 2 and 12 days of their growth in the absence of light. The differences in the apical curvature of the hook and the opening of the cotyledon began after six days of cultivation. Scientists categorized seedlings based on differences in tip shapes and quantified growth in each category. In the lut2 mutant, the lack of lutein leads to a slower accumulation of Pchlide and affects the composition of xanthophyll. No ion leakage, no depletion of antioxidants.
