Prosopis juliflora is a xerophytic, nitrogen‐fixing plant distributed in arid and semi‐arid regions. The fruits of this plant are pods, which have seeds inside, and both pods and seeds have high nutritional value and bioactive potential. Different derivatives can be obtained from the pods and seeds: flour, starch, syrup, protein concentrate, and gums. This review aims to gather information from the literature on P. juliflora. It focuses on the nutritional value, bioactive activity, and technological application of pods, seeds, and their derivatives, highlighting their use in human nutrition and new research perspectives. The pod of P. juliflora can be used in several ways, as it has high levels of nutrients. It is used as a food supplement; it has antimicrobial effects and phytochemicals associated with other bioactive activity. Among the pod derivatives, flour is the most studied and can be widely used in bakery products. The seed of P. juliflora also has high nutritional potential and bioactive activity. Among its other derivatives, the gum stands out and can be used for various purposes in the food industry. To expand the use of pods, seeds, and their derivatives in human nutrition, further studies are needed on chemical composition, bioactive activity, toxicity, and nutritional, bioactive, technological, and sensory effects of their application in food products. © 2023 Society of Chemical Industry.

“…Bioplastics are biodegradable plastics made from the renewable sources [4]. Renewable sources such as potato starch, corn starch, fibres obtained from pineapple, jute, hemp, banana stems [14,15] cassava [16], newspaper pulp [17], waste paper [18], Prosopis juliflora [19], citrus waste [20], cyanobacteria [21], Pseudomonas putida [22,23], Bacillus sp. [24] Employment of new techniques for manufacturing of bioplastics that promote sustainable solution and reduce the plastic waste has been greatly encouraged in recent years [25].…”

Petrochemical based plastics have been widely used as packaging materials, as they have good barrier properties, stiffness, tensile strength & tear strength. Although in great demand plastics have many disadvantages like very low water vapour transmission rate, non- biodegradability etc. which further causes environmental pollution. Keeping in mind about the pollution and harm caused to the nature, newer concepts about the use of bio-plastics came into force. Bio-plastics are produced from the biological sources such as potato, potato peels, corn, sugarcane, wheat, rice, banana peels etc. These plastics are environment friendly & biodegradable, and are safer option than the petroleum-based plastics. These biodegradable plastics break down into carbon dioxide, water & inorganic compounds and degrade completely. The time-line, sources and other important details about the bio-plastics have been presented in this review paper.

“…Introduction of chitosan into plasticized PLA with tributyl o-acetyl citrate (ATBC) conducted to antimicrobial materials with tensile strength at break of~24 MPa, and water vapor transmission rate of 43.91 g m −2 day −1 properties [36]. In other paper, Kasirajan et al [37] reported the production of PLA/chitosan membrane with tensile strength of 17.809 MPa, elongation at break of 300.11%, and oxygen transmission rate of 1614.21 cm 3 /(m 2 •day•atm) from solvent casting method. Two-layer composite film containing rosin modified cellulose nanofiber in PLA coated with chitosan showed good mechanical properties and antimicrobial performance against E. coli and B. subtilis [38].…”

Several recipes based on PLA, bio-plasticizers, and active agents such as vitamin E and cold-pressed rosehip seed oil encapsulated into chitosan by the emulsion method named here as chitosan modified (CS-M) were elaborated by melt compounding for food packaging applications. Resulted biocomposites have been investigated from the point of view of physical-mechanical, thermal, barrier, antimicrobial, and antioxidant properties to select the formulations with the optimum features to produce food trays and films for packaging applications. The obtained results showed that the elaborated formulations exhibit tensile strength and flexibility dependent on their composition being either rigid or flexible, as well as antimicrobial and antioxidant activity, which will potentially lead to prolonged use for food packaging. The recipe with PLA matrix and 40:60 Lapol®108 as masterbarch/polyethylene glycol (MB/PEG) bio-plasticizers ratio was distinguished by an improvement of over 100 times in terms of flexibility compared with neat PLA, while the highest antioxidant activity (36.27%) was recorded for the sample containing a CS-M and MB/PEG ratio of 60:40. An enhancement of ~50% for the water vapor barrier was recorded for PLA/CS-M_100:0 material. By modulating the MB and PEG bio-plasticizers ratio, the design of new eco-friendly food packaging materials with antimicrobial/antioxidant characteristics by using the existing technologies for processing synthetic polymers (melt mixing, compounding, pressing, thermoforming) has been successfully realized.
