Strawberry is a fruit with a short season of harvest. Strawberry is well-known among people all over the world for its distinct flavour, nutritional value, and delicacy. While on the other hand, preserving strawberry and shelf life extension has been a huge difficulty due to their perishable nature. Making effective and sustainable use of already available food processing and preservation technology needs time. Researchers must use advanced techniques like a cool store, modified atmospheric packaging (MAP), cool store, controlled atmospheric storage (CA), various packaging methods, and a variety of chemical and physical treatments to retain commodities for a longer period due to strategic market sales following harvest. Except for the preserving techniques, there is some polysaccharide-based edible coating which has a crucial role in delaying fruit softening, fruit decay, maintaining the increased levels of ascorbic acid and phenols, enhancing the activities of antioxidant enzymes, and reducing membrane damage. During the postharvest stages, there are numerous threats to keep in view regarding the safety and quality of strawberries. In this chapter, we will discuss the benefits and drawbacks of some of the various preservation technologies, as well as how they might be utilised to preserve and a prolonged period of freshly harvested strawberries.
This article reports the three principal groups of compounds for the first time from Adhatoda vasica and Calotropis procera plants species using nuclear magnetic resonance methods in which aliphatic, oxy heterocyclic, and tannins compounds were detected from these plants. The leaves of both species were subjected to testing tyrosinase inhibition and antioxidant activities. ATP bioluminescence use for indirect measurement of the amount of organic residue on the surface of the leaves that provide support to microbial growth. The distinguishing characteristics and intraoperative findings of bacterial diseases involved in treatments were conducted against the positive and negative microbial strains using a scanning electron microscope (SEM). The methanolic extracts of leaves of both species were applied to bacterial strains through broth microdilution method to determine the minimum inhabitation concentrations (MICs) for both species. It was concluded that both plants are a rich resource of bioactive compounds. Their extract may also be used to treat various bacterial diseases and in drug manufacturing.
Highlights
New chemical compounds of oxy‐heterocyclic, aliphatic, and tannins derivatives are isolated from herbal plants as a source of various drugs.
1H NMR spectrum and 13C NMR spectrum of each new derivate were calculated.
NMR‐spectral analysis of new compound of chemistry class was studied and further applied in various bacterial strains.
Tyrosinase inhibition property of bacteria strains by application of active compounds on these strains.
Agar overlay bioassays were used to evaluate intercellular morphological features of strains applied on extracts by electron microscope (SEM).
a‐Glucosidase inhibition assay determined with antioxidants activity through FRAP assay methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
