Green banana biomass: Physicochemical and functional properties and its potential as a fat replacer in a chicken mortadella

Fermented banana feed and nanoparticles: a new eco-friendly, cost-effective potential green approach for poultry industry

The quest for sustainable, alternative, and cost-effective biofeed resources has been driven by the increasing costs and environmental concerns linked to conventional poultry feed. The banana plant (Musa spp.), traditionally valued for its fruit, is gaining recognition as a versatile and sustainable resource for the livestock and poultry industry. Rich in essential nutrients, fibers, and bioactive compounds, banana by-products enhance animal health, improve digestion, and reduce feed costs. Studies reveal that banana plant have potential as natural growth promoters, prebiotics, and antioxidants, contributing to improved feed efficiency and resilience against diseases. The peel of a banana is a good source of vitamins, crude protein (6-9 %), starch (3 %), total nutritional fiber (43.2-49.7 %), and crude fat (3.8-11 %), making it good source of nutrition for animals and birds. In addition, banana's peels contain flavonoids, tannins, phlobatannins, alkaloids, glycosides, and terpenoids. These compounds have antibacterial, growth promoter, antioxidant, stress reducer, anti-cholesterol, antihypertensive, immunostimulants, and anti-inflammatory properties. The banana plant, which is often regarded as agricultural waste, is rich in carbohydrates, fiber, and essential minerals, making it a valuable feed component. Results from experimental studies showed improved feed conversion efficiency, growth performance, and gut health in poultry fed with fermented banana plant-based diets. Fermentation improves the nutritional quality of banana plant biomass by increasing digestibility, reducing anti-nutritional factors, and enriching it with probiotics and bioactive compounds. The fermented banana had a substantial influence on weight gain and feed consumption in chickens. Banana meal may be used into broiler chicken diets at a maximum of 10 % without negatively impacting productivity. Silver nanoparticles (nano-Ag) produced by the banana plant can be used as an alternate growth-promoting supplement for poultry production. This approach offers environmental advantages by minimizing agricultural waste and encouraging more sustainable poultry production practices. Overall, the available studies highlight the considerable promise of fermented banana plants as a sustainable and environmentally friendly option in poultry feeding, tackling both economic and ecological issues faced by the poultry sector.

Traits of Mortadella from Meat of Different Commercial Categories of Indigenous Dairy Cattle

The rising interest in healthier meat options prompted the exploration of alternatives to traditional pork-based products, incorporating meat from different livestock species, feeding regimens, and functional ingredients. This study investigates the production of healthier meat products by examining the physicochemical traits, fatty acid profile, and sensory properties of mortadella made with Cinisara meat of four young bulls and four adult cows, and four females of the Nebrodi Black Pig. All the animals were fed principally on natural resources. Nutritional analysis revealed different levels of moisture, protein, fat, and ash in raw materials, with pistachios contributing to a healthy fatty acid profile rich in monounsaturated and polyunsaturated fatty acids. Formulations using cow meat exhibited higher fat content and caloric value, resulting in sensory attributes such as more intense color, improved fat cube adhesion, and pronounced odors compared to young bull and control mortadella. Fatty acid analysis demonstrated distinctive profiles influenced by the meat type used and, as expected, bovine products showed higher contents of rumenic and other conjugated linoleic acids. Pork mortadella displayed greater ω6 and ω3 values, with a healthier ω6/ω3 ratio comparable to those found in cow products. Young bull mortadella showed the worse atherogenic and thrombogenic indices. The findings underscore the impact of raw materials on the nutritional and sensory attributes of mortadella, emphasizing the necessity for interventions to enhance fatty acid composition in processed meat products.

Green banana resistant starch: A promising potential as functional ingredient against certain maladies

This review covers the significance of green banana resistant starch (RS), a substantial polysaccharide. The food industry has taken an interest in green banana flour due to its 30% availability of resistant starch and its approximately 70% starch content on a dry basis, making its use suitable for food formulations where starch serves as the base. A variety of processing techniques, such as heat-moisture, autoclaving, microwaving, high hydrostatic pressure, extrusion, ultrasound, acid hydrolysis, and enzymatic debranching treatments, have made significant advancements in the preparation of resistant starch. These advancements aim to change the structure, techno-functionality, and subsequently the physiological functions of the resistant starch. Green bananas make up the highest RS as compared to other foods and cereals. Many food processing industries and cuisines now have a positive awareness due to the functional characteristics of green bananas, such as their pasting, thermal, gelatinization, foaming, and textural characteristics. It is also found useful for controlling the rates of cancer, obesity, and diabetic disorders. Moreover, the use of GBRS as prebiotics and probiotics might be significantly proved good for gut health. This study aimed at the awareness of the composition, extraction and application of the green banana resistant starch in the future food products.

Underutilized Green Banana (Musa acuminata AAA) Flours to Develop Fiber Enriched Frankfurter-Type Sausages

This study aimed to develop a fiber-enriched Frankfurter-type sausage by incorporating underutilized green banana flours as a meat extender, replacing wheat flour with banana flours (8%). A low-fat formulation substituting 12% pork fat with 24% banana peel flour was also studied. Sausages were stored at 4 °C/15 days. Cooking loss was low (5.6–4.1%) in all formulations and the substitution of wheat flour with banana flour did not modify moisture and protein composition, while carbohydrate, fiber, and ashes varied with the flour composition. In the low-fat sausages, fiber carbohydrate and ashes increased the most. Texture and color parameters were very similar for high-fat sausages throughout storage, although low-fat sausage showed higher hardness, while chewiness, L*, and whiteness tended to decrease. During the first week of storage, the microbial growth was scarce and then, an increase, except in the low-fat batch, in which growth remained constant. Enterobacteria and Staphylococcus aureus were not detected during storage. Sensory attributes throughout storage were very similar for all high-fat sausages; the odor in the formulations was defined as “different” but not unpleasant. The low-fat sausages, defined as a new product different from conventional sausages, were well accepted by the panelist. Banana flours are a suitable ingredient option to add nutritional value to Frankfurter-type sausages, which can be consumed by the wheat allergic population.
