In this era of green technology, plasma technology is one of the novel techniques intended towards many industries including food industry as a principal application due to less utilization of energy, solvents, and water with minimum impact on food quality. The foremost purpose behind the utilization of nonthermal plasma processing (cold plasma) lies in the retention of freshness of food products along with furtherance of sensory properties as well as functional and nutritional composition. In addition, this technique assists in shelf life extension and carries out desirable modifications in the structure of food and packaging material. This technology has been proven to be advantageous over other technologies since all these processes are carried out at low temperature, hence is highly suitable for heat-sensitive materials. The present review summarizes the mechanism of this plasma technology along with its benefits to the industry, for example improvements in cooking quality, enhancements in enzyme activity, modification of starches, and microbial inactivation. Also, the effects of plasma treatment on characteristics of various food products have been elaborated in this review.

Indigenous fruits such as jambhul, wood apple and vegetables viz., ambadi, ambat chukka were extracted with methanol and analyzed for Total Phenolic Content (TPC), total flavonoid content, ascorbic acid, anthocynin and antioxidant capacity such as ABTS, DPPH and FRAP assay. Total flavonoid content and total monomeric anthocynin were found only in jambhul i.e., 227.38 mg/g CE/g DW, 27.40 mg/g as cyn-3-glucoside as equivalent DW respectively. Increased TPC was observed in the order: jambhul>ambadi>wood apple>ambat chukka. Higher ascorbic acid was observed in order of: jambhul>ambadi>ambat chukka>wood apple. The antioxidant potential of above fruits has been rated in the order: jambhul>wood apple>ambadi>ambat chukka by DPPH and FRAP assay and for ABTS assay Jambhul>ambadi>wood apple>ambat chukka.

Limonia acidissima (wood apple) fruit is edible and used in very limited food preparations. This fruit as well as different parts of the L. acidissima plant is also used as a folk medicine to treat various ailments and reportedly possesses anti-hyperglycemic and anti-hyperlipidaemic activities. The purpose of the present study was to examine the potential uses and applications of L. acidissima to improve the usage of this unexploited fruit based on its nutritive value. This review summarizes recent pharmacognostical aspects, various applications of this fruit in food and non-food industries, and the experimental research work done on L. acidissima. This review will be helpful to create interest toward the lesser-known facts and less documented work done on L. acidissima. This information may be useful in developing new formulations or enhancing the existing products with more therapeutic or nutritive value.
