The experimental design involved the addition of okara to skimmed and semi-skimmed milk at two different levels of concentration (25% and 50%), obtaining cheese prototypes coded as CS-1/CS-2 and CP-1/CP-2, respectively. The chemical characterization of okara showed a high fiber (13.47 g/100 g) and fat content (18.62 g/100 g), with 90% of lipids composed of polyunsaturated fatty acids (PUFAs). The physicochemical properties and safety of the cheese samples during 30 days of storage were evaluated. Fortification allowed the cheeses to reach the minimum levels for the nutritional claims “source of fiber” (3 g/100 g), “rich in fiber” (6 g/100 g), and “rich in unsaturated fatty acids” (40% of total fats). The addition of okara at 50% level made the cheeses more consistent, with pleasant almond flavor but increased lipid oxidation, even though the oxidative test gave values that did not exceed the limits threshold of toxicological concern (30 µg/kg body weight/day). In addition, the samples obtained with skimmed milk (CS, CS-1, and CS-2) were found to be more consistent and with higher yellow index values than the corresponding formulations obtained with semi-skimmed milk.

This study investigated the effects of AF on <i>Salmonella</i>-induced colitis, a severe inflammatory bowel disorder characterized by oxidative damage and inflammatory response. In vitro, antioxidant assays revealed AF's concentration-dependent radical scavenging, significantly reducing electron paramagnetic resonance (EPR) signals for HO<sup>•</sup> and O<sub>2</sub><sup>•−</sup> by 42% and 54%, respectively. In vivo, AF treatment significantly mitigated body weight (BW) loss by 6%, increased colon length by 11%, and reduced liver and spleen weights by 19% and 81%, respectively, compared to the colitis group. Mechanistically, AF suppressed inflammation by downregulating the Toll-like receptor 4 (TLR4)/IκB/nuclear factor-κB (NF-κB)/cyclooxygenase-2 (COX-2) pathway and inhibiting nucleotide-binding domain-like receptor protein 3 (NLRP3) inflammasome activation, thereby lowering levels of pro-inflammatory cytokines (tumor necrosis factor alpha [TNF-α], interleukin 6 [IL-6], interleukin 1 beta [IL-1β]).

This review aims to clarify these interactions by examining several key aspects. It begins by reviewing the mechanisms through which different phyla of gut microbiota degrade bioactive polysaccharides, clarifying their direct interactions. Then, how bioactive polysaccharides influence the relationships within gut microbiota was discussed, focusing on commensalism, mutualism, and competition.

Kiwifruit, particularly the varieties “<i>Actinidia chinensis</i> var. <i>chinensis,”</i> “<i>A. chinensis</i> var. <i>deliciosa,”</i> and <i>Actinidia arguta</i>, are an exceptional source of polyphenolic compounds like flavonoids, stilbenoids, and phenolic acids.

Additionally, kiwifruit effectively safeguards against hepatotoxicity, nephrotoxicity, neuropathy, and neurological disorders. Nevertheless, it is worth noting that kiwifruit consumption may induce allergies due to 13 IgE-reactive compounds. They are proteins and glycoproteins with molecular masses ranging from 10 to 51 kDa. The primary allergen in kiwifruit is a cysteine protease known as Act d 1, which accounts for 50% of the soluble protein extract.

Traditional freezing methods often negatively impact food quality, affecting texture, color, flavor, and so forth. Liquid nitrogen (LN<sub>2</sub>) offers a promising alternative, reducing freezing time and preserving food structure and components. This review examines the use of LN<sub>2</sub> across different food matrices, highlighting its advantages and limitations based on the employed freezing technique. Additionally, innovative LN<sub>2</sub> applications in food processing and transformation are explored. LN<sub>2</sub> has shown notable benefits for seafood, minimizing lipid oxidation and structural damage, leading to improved texture and sensory properties. In meat, it helps preserve protein integrity, limit moisture loss, and maintain tissue structures, enhancing freshness while also contributing to microbiological safety. In vegetable products, LN<sub>2</sub>’s effects depend on cellular structure and water migration. While some studies report losses of polyphenols and flavonoids, others highlight improved vitamin C and antioxidant retention. Beyond freezing, LN<sub>2</sub> is emerging as an innovative tool in food processing, particularly in peeling nuts and fruits, reducing quality degradation, compared to conventional methods. In dough and steamed bread, LN<sub>2</sub> helps maintain textural properties during storage. Additionally, combining the use of LN<sub>2</sub> with encapsulation, microencapsulation, or grinding technique can lead to a stabilization of bioactive compounds. Despite its significant benefits, the scalability of each process can be challenging in relation to the food matrix.
