Effect of calcium oxide nanoparticles produced from Lavetira critica leaf extract on the freshness of fresh‐sliced fruits

Abstract

This study was piloted to assess the fusion of nanoparticles (LCCaNP) from leaf extract of Lavatera critica (LC) and calcium chloride and to observe their impact on the safety of fresh‐sliced fruits and extend their shelf life. LCCaNP were synthesized by mixing calcium chloride and LC leaf extract, followed by the addition of sodium hydroxide. The quality of the produced LCCaNP was proven by conducting different physical and chemical tests. Fresh apples, strawberries, and guavas were independently immersed in diverse concentrated LCCaNP and 2% calcium chloride solution for 5 min. These treated sliced fruits were stuffed in polypropylene plastic bags and stored at 5°C. The total soluble solid content (TSS), pH, firmness, and weight reduction rate, 2,2‐diphenylpicrylhydrazyl (DPPH), and sensory analysis were conducted for the total storage period of 25 days in a 5‐day interval. LCCaNP and calcium chloride were proficient to preserve the fruits for up to 20 days. Our findings showed that LCCaNP‐treated fresh‐sliced fruits had an improved and enhanced shelf‐life than control (nontreated) samples. In conclusion, the leaf of LC is an eventual source for the making of calcium oxide nanoparticles and could serve as an improved food conservation with proficiency to extend the fruit's shelf life for up to 20 days. Novelty impact statement For the first time had produced the natural LCCaNP from a natural plant of LC and evaluated its impact on the safety of fresh‐sliced fruits. The natural nanosized LCCaNP is successfully produced by using the natural Ayurvedic plant of LC. LCCaNP acted as a better food preservative and had the capability to extend the shelf life of apples, strawberries, and guavas for up to 20 days without causing any side effects.

Pouteria caimito fruit derived nanoparticles inhibited the apple ring rot disease as well as extended the shelf-life of sliced apples

“…The zeta potential spectrum showed very low values. Previous numerous scientific reports have been supported in our findings by the approach of the observed lower zeta potential value and the nanosize distribution of the spectrum ( Veeramani et al, 2022a , Veeramani et al, 2022b , Veeramani et al, 2022c ). Hence, these spectra clearly indicate that the nanoparticles produced at nanoscale approach with clear purity.…”

“…For one day, this reaction mixer was left at room temperature, at that time the residue particles were taken and eroded 3 times with distilled water and 15, 000 rpm centrifugation. These particles were powdered by drying them for 24 to 48 hrs in an air-dry oven at 37 degrees Celsius ( Veeramani et al, 2022a , Veeramani et al, 2022b , Veeramani et al, 2022c ).…”

“…It is a highly nutritious fruit, especially for protein, calcium, vitamin A, vitamin C, iron, and thiamin. In a prior analysis, we proved the anticancer efficacy of these fruit extract-based synthesis nanoparticles ( Veeramani et al, 2022a , Veeramani et al, 2022b , Veeramani et al, 2022c ). Pouteria caimito fruit extracts associated with calcium oxide nanoparticles and their protective properties against apple ring rot disease and the life extension of sliced apples have not yet been studied; therefore, we planned to conduct the synthesis of calcium nanoparticles and their above-illustrated biotic actions.…”

“…Phytochemically associated nanoparticles are a potential novel, simple, and friendly model, and they are being focused on by numerous scientists because of their best mechanical way of biological and agricultural industries applications ( Veeramani et al, 2022a , Veeramani et al, 2022b , Veeramani et al, 2022c ). Plants and their constituents for phytochemical-based nanoparticle production are very important in current drug and agent deployment fields because of their effective target regions, low-cost production, and non-toxic properties.…”

“…Several plant parts are used for the synthesis of nanoparticles, such as seeds, leaves, and stems. Root, flower, and fruit ( Veeramani et al, 2022a , Veeramani et al, 2022b , Veeramani et al, 2022c , Roy, 2021 ). However, the making of organic calcium nanoparticles from the calcium chloride and fruit extract of Pouteria caimito has not yet been scrutinized.…”
