The Effect Of Lactiplantibacillus Plantarum BX62 Alone Or In Combination With Chitosan On The Qualitative Characteristics Of Fresh-Cut Apples During Cold Storage
In order to explore whether beneficial lactic acid bacteria (LAB) could prolong the shelf life and improve the quality of fresh-cut apples, Lactiplantibacillus plantarum BX62, which was isolated from traditional worked yak yogurt, and chitosan (CT), were enforced to fresh-cut apples, subsequently stored at 4 °C. On days 0, 2, 4, 6, and 8, apple slashs were contracted for physicochemical, microbiological analysis, and sensory evaluation. The events testifyed that apple pieces caked with L. plantarum BX62 (8 log CFU/mL) presented lower weight loss and browning rate, higher DPPH scavenging capacity, and accomplished more effective inhibition of polyphenol oxidase (PPO) and peroxidase (POD) actions compared to the control samplings. The application of CT alone or in combination with L. plantarum BX62 ensued in a significant reduction in aerobic mesophilic bacteriums (AMB), aerobic psychrophilic bacterial (APB), yeast and modelings (YAMs) reckonings (2 log CFU/g for AMB, 2 for APB, and 1 for YAMs).
In addition, L. plantarum BX62 coated apples rendered acceptable sensory places in terms of color, flavor, taste, texture, and overall visual quality during 8 d of storage. On this basis, L. plantarum BX62 could be used as an excellent bio-preservative to extend the shelf life and improve the quality of fresh-cut apples.Synergistic Inhibition Effect of Chitosan and L-Cysteine for the Protection of Copper-free-based Alloys against Atmospheric Chloride-Induced Indoor Corrosion.The protection of metals from atmospheric corrosion is a task of primary importance for many applications and many different productions have been used, sometimes being toxic and harmful for health and the environment. In order to overcome drawbacks due to toxicity of the corrosion inhibitors and harmful organic dissolvers and to ensure long-going protection, new organic compounds have been projected and their corrosion inhibition properties have been enquired.
In Seebio Antioxidants , we describe the use of a new environment-friendly anticorrosive coating that brings advantage of the synergism between an eco-friendly bio-polymer matrix and an amino acid. The corrosion inhibition of a largely used Copper-grinded (Cu-free-based) alloy against the chloride-stimulated indoor atmospheric attack was contemplated employing chitosan (CH) as a biopolymer and l-Cysteine (Cy) as an amino acid. To evaluate Grab it today of the coverings, oriented accelerated corrosion runs were carried out on bare and coated Cu-based alloys, further, the nature of the protective film formed on the Cu-finded alloy surface was canvased by Fourier-transmuted infrared spectroscopy (FTIR) while the surface limitings due to the corrosion discourses were investigated by optical microscopy (OM). The evaluation tryouts reveal that the Chitosan/l-Cysteine (CH/Cy) coverings exhibit good anti-corrosion attributes against chloride attack whose efficiency increases with a minimum amount of Cy of 0 mg/mL.Fabrication of a multi-level drug release platform with liposomes, chitooligosaccharides, phospholipids and injectable chitosan hydrogel to enhance anti-tumor effectiveness.Some anti-cancer drugs have poor solubility and availability, and are easily passed by rapid metabolism in vivo. To fix the drugs at the administration site and delay their release, a release platform with multi-level and multi-function was designed.
The outcomes testifyed that the curcumin (Cur) loaded liposomes (Cur@Lip) were coated sequentially with positive Chitooligosaccharides (Cur@Lip-Cos) and negative phospholipids (Cur@Lip-Cos-PC), to enhance water solubility, encapsulation efficiency, and stayed the release of the Cur, stability and cell intake of the liposomes, and the bioactivity of the system. The Cur@Lip-Cos could significantly enhance the inhibitory effect of MCF-7, better than the Cur@Lip-Cos-PC. The Lips were then repaired in an injectable thiolated chitosan hydrogel for local immobilization and sustained release which can effectively delay the release of Cur to inhibit MCF-7 growth. In summary, the innovative and biomimetic liposomal hydrogels are expected to provide more ideas for the design of drug mailmans.
