Smart edible coating films can be used in food packaging. For this application, they must have good physical and mechanical properties. Herein, chitosan-beeswax based film is used to preserve Le Conte pears postharvest. The chitosan-beeswax films were characterized using XRD, FT-IR, and SEM analysis. Moreover, all films showed good self-healing aptitudes ranging from 86.7 to 96.3. The film treated with pollen grains showed an enhanced water contact angle compared with the chitosan film. The chitosan-beeswax/pollen grain film exhibited a two-fold lower WVTR value compared to the chitosan film, and showed the tendency to increase the stiffness of the film. The elongation% at break was reduced from 35.81 to 14.09. Fruit quality parameters were determined in cold storage for 105 days during shelf life after a simulated marketing period of 7 days. All coated fruits successfully showed decrease in weight loss, decay and rate of softening. Therefore, chitosan-beeswax/pollen grains can be considered safe and effective coating for the fruit preservation.

Plant metabolites known as cucurbitacins are known to impart an unpleasant bitter taste to edible fruits and even lead to severe health complications after the ingestion of relatively high amounts. In this study, an analytical method based on reversed phase liquid chromatography with combined detection by UV spectroscopy and atmospheric pressure chemical ionization high-resolution single/tandem mass spectrometry was applied to confirm the occurrence of four cucurbitacins (B, D, and R, and 23,24-dihydro cucurbitacin B) previously inferred in unexpectedly bitter-tasting fruits of an Italian variety (Scopatizzo) of unripe melon (Cucumis melo L.), known for the sweetness of its fruits.

As the third largest source of energy in addition to carbohydrates and proteins, lipids provide the body with more than twice as much energy as carbohydrates and proteins and are the accumulated "fuel bank" of the body. They are widely stored in animals, plants and microorganisms and are effectively extracted for dietary use by improved and novel technologies. Under the pressure of the current environment, we should immediately look for new strategies to improve or develop dietary lipids that are compatible with the development of the future food industry, in order to mitigate the environmental and climatic degradation caused by the lipid-producing activities of the animal husbandry industry, to avoid the contradiction between the demand for high quality of human beings and the strain on the resources, and to reduce the health risks caused by saturated fats and trans-fats in meat products.

Pimpinella brachycarpa Nakai is a perennial plant that has been widely used as a traditional medicine. However, the comprehensive analysis of primary and secondary metabolites and antioxidant activities in different organs (flowers, leaves, stems, and roots) has not been extensively studied. A comprehensive analysis using GC-qMS, GC-TOFMS, and HPLC metabolomic analyses identified 66 known metabolites in different organs of P.

In this work, environmentally friendly fluorescent carbon dots (C-dots) were developed for the purpose of thiram identification in the leaves of perilla plants. Powdered plant petals from were hydrothermally combined to create C-dots. Analytical techniques, such as scanning electron microscopy, energy dispersive X-ray spectroscopy, high resolution transmission electron microscopy, Raman spectroscopy, ultraviolet spectroscopy, Fourier transmission infrared spectroscopy, and photoluminescence were employed to examine the properties of C-dots.

In present investigation, the effort is done to enhance the grain quality in brewer's rice cultivar Yamadanishiki with the plasma treatment of caryopsis (rice fruit) on ripening process. Seedlings transplanted from a paddy field into pots were grown in a greenhouse, and each caryopsis was treated with plasma on 1, 5, 10 and 15 days after flowering (DAF). The ratio of white-core grains to total number of grains was decreased in the grains treated on DAF1, same level on DAF5, and increased on DAF10 and 15, respectively, compared with control grains.
