Abstract
We studied the effect of the calyx of cape gooseberry nanoparticles manufactured by a novel technique. There are several methods, such as jet mill, spray freezing, supercritical anti-solvent technique (SAS), and high-pressure homogenization, available for the production of drug micro/nanoparticles to improve drug solubility. Anti-solvent precipitation is also used to prepare micro- and nanosized particles to explain their effects on different foodborne pathogens, contaminated bacteria, and some fungi. Results indicated that nanoparticles of the cape gooseberry calyx contained higher antioxidant activity than that found in the normal calyx, seed, and juice. While studying the effect of cape gooseberry calyx nanoparticles on microorganisms, it was found that the zone of inhibition was highly positive against Bacillus cereus, B. subtilis, Staphylococcus aureus, Clostridium perfringens, and Salmonella typhimurium compared to that of the normal cape gooseberry calyx. All species of molds, including Mucor sp., Aspergillus niger, Penicillium sp., and Alternaria sp., and yeasts like Saccharomyces cerevisiae and Rhodotorula glutinis were affected by nanoparticles of the cape gooseberry calyx compared to those of the normal calyx.
Highlights
The cape gooseberry (Physalis peruviana L.) is an annual plant belonging to the family Solanaceae, and it is a short-lived perennial that can grow up to one meter (Ramadan, 2011)
transmission electron microscopy (TEM) images revealed that a thin layer of organic material surrounded the nanoparticles, which is indicative of the cape gooseberry calyx
We selected the calyx to prepare nanoparticles, and the results showed that its antioxidant capacity increased 2-fold compared to normal calyx for total phenols, DPPH, ABTS, and FRAB, which were 85.088 ± 4.093, 69.517 ± 1.131%, 1.667 ± 0.012 (g Trolox/g sample), and 1.604 ± 0.180 (g Trolox/g sample), respectively
Summary
The cape gooseberry (Physalis peruviana L.) is an annual plant belonging to the family Solanaceae, and it is a short-lived perennial that can grow up to one meter (Ramadan, 2011). It contains vitamins A and C, some of the vitamin B-complexes, and minerals, such as phosphorus, iron, potassium, and zinc Salazar et al, 2008). Phenolic compounds of gooseberry have been extensively studied for their health properties from the epidemiological point of view, and their functionality depends on their content, intake, and bioavailability Bioavailability of these compounds can be affected by microstructure and binding of phenolic compounds within the food matrix, which are directly related to fruit processing (Balasundram et al, 2006)
