The effect of banana leaf package on the shelf life of rainbow trout fillet in comparison with plastic bags

Abstract

The aim of this study was to evaluate the effect of banana leaf extract on the quality and shelf life of rainbow trout compared to plastic bags at freezing temperature for 40 days. For evaluating this propose, the antioxidant activity of banana leaf extract was assessed. In addition, the shelf life of fish filets was determined by measuring thiobarbituric acid (TBA) and pHof fish. The banana leaves extract showed the highest content of vitamin E (5.8 ± 0.61 mg /g) and carotenoids (12.8 ± 0.1 mg /g). The potential of Cu (II) reduction the extract was 1.76 ± 0.09. The magnitude of modification in TBA and pH of the packed fish with banana leaves were less than the control samples. The present study demonstrated that the use of banana leaf extract will retard lipid oxidation in fish. fillet during freezing storage that may due to its strong antioxidant properties.

Banana plant as a source of valuable antimicrobial compounds and its current applications in the food sector

“…BPE of M. acuminata successfully prevented oxidation of fish oil (Anal et al, 2014) and concentrate as well as freshly squeezed orange juices (Ortiz et al, 2017). Ahmadi et al (2019) demonstrated the effects of banana leaf extract on the consistency and shelf life of rainbow trout fillet, compared with freezing in plastic bags for 40 days. The extract successfully inhibited lipid oxidation in the fish fillet during freezing, which may be attributed to its high antioxidant capacity.…”

“…Banana leaves are large, may be 2.7 × 0.6 m in size, flexible, and waterproof. They are suitable for packaging and serving foods due to their large waxy surface (Ahmadi et al, 2019). They are also rich in fibers, flavonoids, polyphenols, and tannins (Al-Mqbali & Hossain, 2019).…”

Banana and its by‐products: A comprehensive review on its nutritional composition and pharmacological benefits

“…Bananas are considered to be a valuable dietary component due to their high content of dietary fiber, essential vitamins, and minerals. Banana peel makes up around half of the total mass of the fruit (35%–50%) out of all by‐products of the banana such as pseudo‐stems, leaves, and blossoms (Ahmadi et al, 2019; Gomes et al, 2022). The banana pseudo‐stem (BPS) grows around 6–7.6 m tall, bears flowers, leaves, and fruits.…”

“…Banana leaves are large, flexible, waterproof, and around 2.7 × 0.6 m in size. Due to their substantial waxy surface, they are appropriate for food packaging and food serving (Ahmadi et al, 2019).…”
