Effect of Gum Arabic from Acacia senegal var. kerensis and Texturized Soy Protein on Pysico-Chemical Properties of Protein-Rich Snack Stick

food and Nutrition Sciences 2025年第1期16卷 28-43页

作者： Edward Mukundi Njeru Mary Omwamba Symon Maina Mahungu department of Dairy Food Science and Technology Egerton University Njoro Kenya

Protein-energy malnutrition (PEM) as a result of poor nutrition, especially for deprived resourced households, is a big health concern in the world. According to the World Health Organisation, PEM accounts for 49% of the 10.4 million deaths of children under five that take place in developing countries. The aim of this study was to evaluate the influence of gum Arabic (GA) and texturized soy protein (TSP) and their interactive effect on proximate, functional, and textural properties of the protein-rich snack stick produced from ground green maize, GA powder, and ground TSP. GA varied at 0%, 4%, 8%, and 12%, while TSP varied at 0%, 12%, 24% and 36%. The 5 cm long protein-rich snack sticks were made using a sausage stuffer and baked in an oven at 110˚C for 1 hr 30 minutes. The snack sticks were subjected to proximate, functional and textural analysis using the standard methods. Increasing GA resulted in a significant (p p < 0.05) increased the protein content (32.46%), Ash content (3.6%), fat (11.96%), and moisture content (16.25%) of protein-rich snack sticks. The interactive effect between GA and TSP led to a decrease in fibre and carbohydrates. Results from this study show GA and TSP significantly enhanced the physico-chemical properties of protein-rich snack sticks. A sample with 4% GA and 36% TSP is recommended for the best physico-chemical attributes of the protein-rich snack stick.

Docosahexaenoic acid， folic acid， and phosphatidylserine co-intervention alleviate cognitive impairment in D-galactose-induced aged mice

Following the aging of the population， cognitive impairment is becoming a major public health issue. Research in recent years has highlighted the potential of docosahexaenoic acid (DHA)， folic acid (FA)， and phosphatidylserine (PS) to improve synaptic plasticity and reduce inflammatory response. However， whether a combined intervention is more effective than using these supplements alone remains unclear. To investigate this， we conducted an experiment on D-galactose-induced aging mice and found that the combining DHA， FA， and PS (DFP) improved spatial learning memory. Moreover， the DFP treatment restored cognitive performance by regulating antioxidant levels， inhibiting microglia activation， and reducing inflammation. The treatment also increased the expression of neurotrophic factors and synaptic-related proteins in the hippocampal region of the brain. Our findings suggest that the supplementation of DPF could be more beneficial than using DHA alone. This combined intervention could improve neurotrophic factor expression and decrease neuroinflammation in the brain of mice， thus reducing neuron damage and enhancing synaptic plasticity. In summary， our results indicate that the combined supplementation of DFP may improve cognition， and may be more effective than supplement with DHA alone.

Structural analysis of a neutral polysaccharide ATP-1 from the red seaweed Asparagopsis taxiformis and its immunomodulatory effects on RAW264.7 macrophages

As a seaweed supplement， the powdered， entire herb of Asparagopsis taxiformis can effectively promote immune response in animals. However， the active factors responsible for this effect are currently unknown. A novel polysaccharide， ATP-1， was isolated and purified from the red alga A. taxiformis， and its structural and immunomodulatory properties were determined. ATP-1 is a neutral polysaccharide with a molecular weight of 307.978 kDa and is primarily composed of galactose (94.07%)， glucose (1.27%)， and xylose (4.66%). Scanning electron microscopy and atomic force microscopy revealed that ATP-1 had an amorphous structure and was composed of molecular chain entanglement and intramolecular hydrogen bonding interactions. The microstructure of ATP-1 exhibited asymmetric sheet–like cracks and pores. Results from immunomodulatory activity showed that ATP-1 promoted inducible nitric oxide (NO) synthase and cyclooxygenase (COX)-2 protein expression in RAW264.7 macrophages， improved macrophage phagocytic ability， and stimulated cytokine production (NO， tumor necrosis factor [TNF]-α， and interleukin [IL]-6). Quantitative proteome analysis identified 178 differentially expressed proteins (70 upregulated and 108 downregulated) that were involved in various molecular pathways， among which， TNF was one of the 20 most common and significant signaling pathways in inflammation and immunoregulation. Western blotting indicated that ATP-1 significantly upregulated the expression of IKKα， IKKβ， COX-2， and TNF-α proteins in the TNF pathway. In contrast， ATP-1 downregulated the expression of IκBα， Fas， and AIPI. Results from molecular docking suggested that hydrogen bonding predominantly contributed to the affinity between TNF-α and galactose， glucose， and xylose. These findings indicated that ATP-1 may play an immunomodulatory role by activating the TNF signaling pathway. ATP-1 enhanced macrophage phagocytic capacity and stimulated the production of cytokines NO， TNF-α， and IL-6， thereb

The ameliorative effects of ginger against heat-induced oxidative stress and mitochondrial dysfunction in Caenorhabditis elegans

Ginger， rich in gingerols and shogaols， exhibits multiple biological properties. However， the mechanisms underlying its thermotolerance remain unclear. The study employed network pharmacology and experimental validation in Caenorhabditis elegans to investigate how gingerol-related compounds within ginger extract (GE) mitigated damage caused by heat stress (HS). A total of 18 types of gingerol analogues were identified in GE， among which 6-， 8-， and 10-gingerol， as well as 6-， 8-， and 10-shogaol were quantified. Collectively， these six compounds accounted for 54.4% of the total composition. Supplementation with 15 μg/mL GE significantly extended heat-stress lifespan by 20.30%， while the combination of the six major gingerols and shogaols at the same concentration prolonged lifespan by 18.93%. Additionally， pretreatment with GE and the combination alleviated HS-induced oxidative damage by eliminating reactive oxygen species (ROS) and upregulating antioxidant enzymes. Network pharmacology analysis suggested that the MAPK pathway may play a crucial role in thermotolerance. Experimental findings confirmed that ginger attenuated oxidative damage through the activation of SKN-1/Nrf2 and DAF-16/FOXO via the MAPK pathway. Moreover， GE stabilized mitochondrial membrane potential and restored ATP levels， thus preserving mitochondrial function during heat exposure. Further investigations using molecular docking and molecular dynamics simulations revealed that shogaols， with more stable binding affinities for KEAP1 protein， exhibited more potent effects than gingerols in prolonging lifespan and reducing ROS levels under HS conditions. In short， gingerol analogues from ginger conferred thermal resistance to nematodes by mitigating oxidative damage and mitochondrial dysfunction.
