Jamun (Syzygium cumini L.) is a tropical fruit crop that belongs to the Myrtaceae family (Singh, Paswan, & Rai, 2019).). India and Indonesia are viewed as the origin of jamun fruits. Jamun has recently become famous for its high nutritional value in food processing areas. Jamun provides ellagic acid and glucoside jamboline that reduces blood sugar and has excellent diabetes control; it is very effective to treat jaundice, kidney stone, blood pressure, sore throat, constipation, vomiting, and diarrhea. As a source of food nutrients and phytochemical, jamun fruit comes to the attention of food manufacturers and food scientists (Bukya & Madane, 2018). This fruit is only accessible in June and July months during monsoon. The production of jamun fruits is unorganized in India, with significant annual losses between 20% and 30% after the harvest (Patil, Thorat, & Rajasekaran., 2012). Jamun fruits should be preserved and processed into valuable products to minimize post-harvest losses. A large number of food products are prepared from Jamun fruits. During jamun juice processing a large amount of pomace is produced which is not finding any appropriate use except for the utilization as an animal feed or landfilling. Majority of by-products obtained from the food industry are dumped in open space (Singh, Panesar, & Nanda, 2006). Fruit pomace can lead to a number of environmental challenges, such as surface and groundwater contamination, unless managed properly. Percolates produced from such by-products are responsible for the degradation of oxygen throughout the soil and the

Jamun (Syzygium cumini L.) fruit is an underutilized source of bioactive phytochemicals. Therefore, preserving this fruit in various forms over the year is necessary. Spray drying can effectively preserve jamun juice; but the stickiness issue of fruit juice powder mainly arises during the drying, which may be overcome by using different carriers. Consequently, this experiment aimed to ascertain the effect of different carrier types (maltodextrin, gum arabic, whey protein concentrate, waxy starch, and maltodextrin: gum arabic) on the physical, flow, reconstitution, functional, and color stability of spray-dried jamun juice powder. The physical parameters of the produced powder such as moisture content, bulk, and tapped density were in the range of 2.57%-4.95% (w.b.), 0.29-0.50 and 0.45-0.63 g/mL, respectively. The powder yield ranged between 55.25% and 75.9%. The flow characteristics, Carr's index and Hausner ratio, were in the range of 20.89-35.90 and 1.26-1.56, respectively. Reconstitution attributes viz., wettability, solubility, hygroscopicity, and dispersibility were in the range of 90.3-199.7 s, 55.28%-95%, 15.23-25.86 g/100 g, and 70.97%-95.79%, respectively. The functional attributes include total anthocyanin, total phenol content, and encapsulation efficiency, were in the range of 75.13-110.01 mg/100 g, 129.48-215.02 g GAE/100 g, and 40.49%-74.07%, respectively.The L*, a*, and b* values ranged from 41.82 to 70.86, 14.33 to 23.04, À8.12 to À0.60, respectively. A combination of maltodextrin and gum arabic was found effective in producing jamun juice powder with appropriate physical, flow, functional, and color attributes.

Elephant foot yam starch (EFYS) is modified by the pulsed electric field (PEF, 4–16 kV cm−1) and used for the development of the biodegradable film. The increase in PEF intensity increases the oil (1.66–2.22 g g−1) and water absorption capacity (1.79–2.08 g g−1) and reduces the gelatinization temperature (Tg) and enthalpy (ΔΗ). Storage modulus (G') is found to be higher than loss modulus (G"), indicating strong gel characteristics of EFYS. Electrical intensity affects the degree of crystallinity and disrupts the granule's surface. Film prepared with PEF‐modified EFYS and different concentrations of polyvinyl alcohol (PVA, 25%, 50%, and 90%) shows that the increase in the concentration of PVA results in increased thickness, tensile strength, % elongation, water vapor permeability, water vapor transmission rate, seal strength, and solubility. PEF modification increases the film's mechanical and moisture barrier properties. The study proves that PEF changes the physico‐functional and structural characteristics of EFYS, making it suitable to be used in the biodegradable film.
