Optimisation of fish gelatin and red pitaya peel powder edible film production

International Journal of Food Science & Technology, Journal Year: 2023, Volume and Issue: 58(10), P. 5578 - 5590

Published: June 25, 2023

Summary Growing awareness of the environmental devastation caused by plastic packaging, particularly in food industry, has led to emergence concept a renewable and environmentally safe consumable film as an alternative plastic. Red pitaya (dragon fruit) peel (RPP), which high pectin content, can be used additional ingredient or co‐biopolymer enhance functional properties fish gelatin (FG) edible film. Edible films were produced using casting techniques varying concentrations FG (3.2%–8.8% w/v) RPP (0.2%–1.0%) with aid Central Composite Design (CCD) Response Surface Methodology (RSM) Expert 13's software. The optimal formulation consisted 5.97% (w/v) 0.45% RPP. Increasing affected thickness (0.18–0.36 mm), water solubility (46.72%–66.78%), brightness (60.04–79.02), redness (7.08–28.36), yellowness (2.48–8.44), opacity (0.85–2.58) physical properties. Mechanical testing revealed tensile strength between 2.76 9.34 MPa break elongation 82.78% 153.89%. results suggested mechanical RPP‐based greatly concentration gelatin.

Comparative Analysis of Shelf-Life, Antioxidant Activity, and Phytochemical Contents of Australian-Grown and Imported Dragon Fruit under Ambient Conditions

Horticulturae, Journal Year: 2024, Volume and Issue: 10(10), P. 1048 - 1048

Published: Oct. 1, 2024

Dragon fruit (Hylocereus spp.), renowned for its aesthetic appeal and rich antioxidant content, has gained global popularity due to numerous health benefits. In Australia, despite growing commercial interest in cultivating dragon fruit, there is uncertainty local growers stemming from competition with imported varieties. Notably, a lack of comparative research on the shelf-life, activity, phytochemical contents Australian-grown versus which crucial enhancing market competitiveness consumer perception. This study compares content fruits under ambient conditions, addressing competitive challenges faced by growers. Freshly harvested white-flesh undatus) red-flesh (H. polyrhizus) were sourced Queensland Northern Territory an importer Queensland. All assessed key quality parameters including peel color, firmness, weight loss, total soluble solids (TSS), pH, titratable acidity (TA), phenolic (TPC), flavonoid (TFC), ferric reducing power (FRAP), cupric capacity (CUPRAC), betalain (TBC), anthocyanin (TAC). The results indicate that white exhibited average one day longer shelf-life less color degradation, better firmness retention, decline TSS, compared fruits. red showed similar overseas. Antioxidant activities phytochemicals consistently higher throughout their shelf-life. These findings offer physical retain more nutritional value, could enhance marketability.

Development of Indicator Film Based on Cassava Starch–Chitosan Incorporated with Red Dragon Fruit Peel Anthocyanins–Gambier Catechins to Detect Banana Ripeness

Polymers, Journal Year: 2023, Volume and Issue: 15(17), P. 3609 - 3609

Published: Aug. 31, 2023

Banana ripeness is generally determined based on physical attributes, such as skin color; however, it considered subjective because depends individual factors and lighting conditions. In addition, improper handling can cause mechanical damage to the fruit. Intelligent packaging in form of indicator film incorporated with anthocyanins from red dragon fruit peel has been applied for shrimp freshness detection; this low color stability during storage, necessitating addition gambier catechins a co-pigment increase anthocyanin stability. Nevertheless, characteristics films that contain their applications bananas have not studied yet; therefore, study aims develop characterize were detect banana ripeness. study, made via solvent casting.

This study investigated the effect of exogenous plant growth regulators (PGR), namely jasmonic acid (JA) and methyl jasmonate (MeJA), on physicochemical properties flesh peels red-fleshed dragon fruit (Hylocereus polyrhizus). The was sprayed with 100 1,000 ppm JA MeJA at 15 22 days anthesis harvested after 35 days. Then, were analyzed for total soluble solids (TSS), betacyanins, betanin, phenolics (TP), flavonoids (TF), color characteristics. contained significantly higher (p<0.05) TP antioxidant activities compared to flesh. No significant difference detected between variables in peels, except betacyanins (~295.6 ~299.9 mg/100 g) (~614.1 566.1 mg GAE/100 recorded control MeJA, respectively. In flesh, MeJA-treated possessed highest (~139.2 g), betanin (~356.0 mg/g), (~244.9 TF (~329.0 CE/100 Trolox equivalent capacity (TEAC) (63.2 µmol TE/g) reducing power (~21.5 TE/g).
