Yolk-free mayonnaise analogs stabilized by modified kudzu insoluble dietary fiber (KIDF): Effects of KIDF type, concentration and oil fraction on rheological, textural, stability and sensory properties.

This study evaluated the chemical composition and in vitro antioxidant activity of sorghum bran, extruded whole-grain sorghum, and a dry phenolic extract from sorghum bran, and evaluated the dry phenolic extract from sorghum bran toxicity and oxidative stress resistance using nematode model (C. elegans). Sorghum bran presented higher content of moisture, ash, lipid, total and insoluble fiber, resistant starch, condensed tannins, total phenolics, flavonoids, anthocyanins, free and bound phenolic acids, and in vitro antioxidant activity compared to extruded sorghum. Extrusion reduced bioactive compound content and antioxidant capacity. Dry phenolic extract remained a source of phenolics with strong antioxidant activity. Also, it presented hormetic behavior, being pro-oxidant in high doses and an antioxidant in appropriate doses, in the toxicity and resistance stress test. Concentrations up to 0.4μM were safe for C. elegans, whereas 4μM reduced survival. Therefore, sorghum bran and its extract have potential for developing functional products.

The hydration properties of food-derived insoluble dietary fiber: Multi-scale regulation of component heterogeneity and size effect

The aim of this trial was to provide a fibrous supplement in the transition diet of sows to decrease sows' constipation, improve farrowing kinetics, increase colostrum antibodies, and modulate sows' and piglets' microbiota. At day 90 of pregnancy sows were fed a standard gestation diet until farrowing (CON, n = 101) or a standard gestation diet added of 400 g of a fibrous supplement (40 % wheat bran, 25 % lignocellulose, 25 % citrus pulp, and 10 % guar gum) (FIB, n = 101). After farrowing, sows were fed a standard lactation diet, and FIB sows were fed 400 g of the fibrous supplement on top of the feed for five days. Sows from FIB had a lower (p < 0.01) incidence of constipation pre-farrowing and on the day of farrowing. Sows from FIB had a 23 min shorter (p = 0.01) farrowing duration compared to CON-sows. Sows from CON had a higher (p < 0.01) feed intake on days two and three post-farrowing. Both IgG and IgA concentrations were higher in the FIB-supplemented sows (p = 0.01). The fecal microbiome of sows and piglets was similar (p > 0.43) between groups. During the first week of life, piglets born from FIB-sows had decreased (p = 0.04) diarrhea incidence. In conclusion, the benefits of the fibrous supplement were evident in peripartal sows by decreasing farrowing duration and constipation and by increasing the concentration of immunoglobulins in the colostrum. For newborn piglets, the fibrous supplement fed to the sows did not significantly alter the fecal microbiome of sows and their litters. Nevertheless, benefits were observed in their resistance to neonatal diarrhea. Thus, using a fiber supplement in transition diets in farms may ease the management in the farrowing room and improve early-life robustness in piglets, which may decrease medication demands during the first week, contributing to more efficient neonatal care and better overall litter performance.

Physical modulation of starch/non-starch polysaccharide complexes for tailored functional foods: A comprehensive review.

The coexistence of non-starch polysaccharides and resistant starch (RS) impacts the physiological functions of dietary fiber, especially the availability of dietary fiber with some specific structures (e.g. insoluble dietary fiber, IDF). Therefore, three complexes with different ratios of RS/IDF from tiger nuts were prepared, followed by an investigation of their corresponding physicochemical and structural properties, as well as the regulatory role in gut microbiota. The results indicated that the complex with RS/IDF ratio of 5/95 (H-IDF) had the greatest water retention, water swelling and oil retention capacities. All three complexes had a similar amylopectin/amylose ratio, which attenuated the impact on microbial fermentation. However, the complex with RS/IDF ratio of 40/60 (L-IDF) had the greatest potential to promote microbial fermentation demonstrated by severe morphological damage. Furthermore, the fermentation of L-IDF led to the greatest generation of acetate and butyrate, but the lowest generation of isobutyrate. Meanwhile, the fermentation of L-IDF enhanced Prevotella abundance, accompanied by a reduced Firmicutes/Bacteroidetes ratio and pathogenic bacteria in terms of Proteobacteria and Escherichia-Shigella. The increased butyrate levels during 24 h fermentation might be primarily due to the enhanced abundance of Faecalibacterium in the early phases and Bifidobacterium in the later phases. The further analysis of functional prediction consistently supported a significantly up-regulated carbohydrate metabolism and down-regulated amino acid metabolism following L-IDF fermentation. This study might highlight a new approach for designing complex carbohydrates with targeted intestinal health functions via the regulation of the RS/IDF ratio. © 2026 Society of Chemical Industry.

There is a growing consumer interest in foods that not only provide nutritional value and convenience, but also promote health benefits through regular consumption. In this context, green banana flour has emerged as a promising alternative for innovative product development. This study evaluated the physicochemical, technological and sensory properties of savory biscuits formulated with green banana pulp (PF) and pulp/peel mixed flours. Four formulations were developed: a control (0-PF), prepared with sweet and sour cassava starches, and three formulations in which 50% of the total cassava starch was replaced with green banana flours containing different pulp-to-peel ratios, 80-PF (80:20), 90-PF (90:10) and 100-PF (100% pulp flour). The 80-PF and 90-PF formulations exhibited higher protein, lipid, and ash contents, whereas all three enriched formulations (80-PF, 90-PF and 100-PF) showed increased levels of total dietary fiber and resistant starch. Texture and thickness values decreased with the increasing proportion of PF and mixed flours. Structural analysis revealed a reduction in both total and open porosity in the 80-PF, 90-PF and 100-PF biscuits, which was associated with increased firmness. All formulations achieved mean sensory scores above the acceptability threshold. Notably, the 90-PF formulation received the highest score for texture, likely due to its denser internal matrix and optimal crunchiness, as confirmed by the JAR analysis. These findings support the use of green banana pulp and pulp/peel mixed flours as functional ingredients for developing nutritionally enhanced, fiber-rich savory biscuits with desirable textural and sensory properties. © 2026 The Author(s).

ABSTRACT The rising demand for functional low-calorie ingredients with improved powder stability has increased interest in soluble dietary fibers (SDFs) as alternatives to conventional maltodextrins. These fibers differ in molecular structure and water interaction, influencing their ability to form stable amorphous matrices during spray drying. However, direct comparative evaluations of their intrinsic physicochemical and thermal properties remain limited. This study compared commercial Orafti® inulin (inulin), TIC PRETESTED® GUM ARABIC FT POWDER (gum arabic), Nutriose®FB 06 (nutriose), and STA-LITE®III Polydextrose (polydextrose) to elucidate their structure – function relationships as standalone glass formers. Each fiber was characterized for moisture content, water activity, solubility, hygroscopicity, morphology (field emission scanning electron microscopy (FE-SEM), particle size distribution (PSD), universal attenuated total reflectance-fourier transform infrared spectroscopy (UATR-FTIR), X-ray Diffraction (X-RD), water sorption isotherm WSI , and differential scanning calorimetry (DSC). All fibers exhibited very high solubility > 99 % , with inulin achieving 100 ± 0.00 % . Gum arabic showed the highest moisture content 7.22 ± 0.001 % but the lowest water activity 0.167 ± 0.008 , while polydextrose recorded the highest a W 0.335 ± 0.01 . Hygroscopicity ranged from 0.000063 g H 2 O g − 1 solid 24 h − 1 (inulin) to 0.000085 g H 2 O g − 1 solid 24 h − 1 (gum arabic). The Guggenheim – Anderson – de Boer (GAB) model accurately described sorption data R 2 > 0.90 , revealing differences in monolayer moisture 0.062 − 0.175 and multilayer adsorption. Gum arabic and nutriose exhibited higher glass transition temperatures 124.19 ± 1.00 deg C − 102.19 ± 1.00 deg C , respectivley , indicating greater resistance to plasticization, whereas inulin showed lowest T g 43.52 ± 1.00 deg C due to its semi-crystalline structure. Overall, synthetic resistant dextrins (gum arabic and nutriose) provided the most balanced performance in solubility, hygroscopic stability, and thermal resistance, supporting their potential use as sustainable glass formers in spray-dried food systems with extended shelf life

Aim: Bangladesh produces a huge number of pineapples in the hilly areas with its medium-high land. The country has several pineapple jam and jelly processing industries. But after processing into jelly, the pomace is dumped here and there, which creates environmental pollution. Thus, the objective of the study was to utilize the pineapple pomace for processing into pomace balls as laddus with its better shelf life and quality studies. Methods: The pineapple pomaces were treated with different proportions of potassium metabisulfite (KMS) and potassium sorbate (KS). Then the prepared laddus were packed into polyethylene terephthalate (PET) boxes and kept at room temperature for further studies. Results: The laddus treated with preservatives had higher total soluble solids, energy value, crude fiber, crude protein, vitamin C, β-carotene, and total sugars. Both laddus showed a trend of decreasing water activity. After 60 days of storage, tests for microbes and mycotoxins showed that the treated laddus were free of both, while the control sample showed some microbial activity. The developed pomace balls (T2, T3, and T4) also had acceptable levels of preservatives, KMS, and KS, both alone and in combination (KMS + KS). The levels were 71.28 ppm, 78.01 ppm, and 110.31 ppm, respectively. T4 laddus were the best of the formulations when it was evaluated for its color, texture, and low water activity. The cost-benefit ratio was evaluated considering the inputs required and the benefits of the product. Conclusions: The preservative-treated laddus could be stored for more than 60 days, whereas the control laddus could only be stored for 30 days. The cost-benefit ratio for the laddus was 1:1.33. The agro-food processing industries and small-scale pineapple processors could apply this technology for producing and marketing the pomace ball with a shelf life of up to 60 days.

The feed carbon‑nitrogen (C:N) ratio and carbohydrate type (CT – starch vs. non-starch polysaccharides (NSP)) are important due to their potential to improve pond's production and mineralization capacity. This experiment investigates the impact of feed C:N ratio and CT on feed intake of fish, their growth parameters, body composition, and the natural food web in a carp-tilapia pond polyculture. The polyculture consists of catla ( Catla catla ), rohu ( Labeo rohita ), Silver carp ( Hypophthalmichthys molitrix) , and mono-sex Nile tilapia ( Oreochromis niloticus ). The study employs a three-by-two factorial design, including three feed C:N ratios (low, medium, and high) and two feed carbohydrate types (CT – starch-diet (rich in starch but also contains NSP), and NSP-diet (rich in NSP but also contains starch)). Results suggest that increasing the feed C:N ratio does not decrease fish productivity at the pond level. The effect of feed C:N ratio on each of the four species in the polyculture revealed that the growth of rohu and catla did not decrease with a high feed C:N, whereas the growth of silver carp improved and of tilapia decreased. The feed carbohydrate type notably influenced the overall pond fish production, by 27 % when using NSP-diets compared to starch-diets ( P < 0.05). The effect of feed CT on each species showed that the biomass gain and growth of rohu and catla were not affected by NSP-diets, while growth of silver carp and tilapia were improved by NSP-diets. Since silver carp mostly feeds on natural food in pond systems, their enhanced growth when fed high carbohydrate diets (high C:N ratio) – especially those rich in non-starch polysaccharides (NSP-diet) – suggests that these diets improved natural food production in the pond. The production and protein content of tilapia went down when fed a high C:N feed. This confirms that tilapia could not fully compensate for low protein in their diet through the consumption of natural food. This limitation is likely due to the intense grazing pressure exerted by four species on the available natural food, which also obscures the effects of the feed C:N ratio and carbohydrate type on the natural food web parameters. Apart from improved fish production, other observed positive effects of the NSP-diet in this experiment were low TDS in pond water and stable phytoplankton diversity as compared with the starch-diet. Considering that the total fish and carp production remained unaffected by the feed C:N ratio ( P > 0.05), as did the overall fish protein content ( P > 0.05), we can conclude that protein-rich diet (low C:N) is less necessary for pond culture system because a carbohydrate-rich diet (High C:N) can yield similar production. Furthermore, regardless of the feed C:N ratio, the NSP-diet consistently enhanced total pond fish production. This allows feed formulators greater flexibility in choosing plant-based NSP-rich feed ingredients when making pond feed. • Increasing feed C:N ratio does not decrease fish production in pond. • An NSP-rich diet improves fish production in ponds. • An NSP-rich diet may enhance natural food production in ponds. • In pond polyculture, silver carp and tilapia benefit from an NSP-rich diet. • Pond feeds can accommodate higher levels of plant-based by-products.

Introduction: Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal disorder, with a significant impact on quality of life, particularly among young adults. The objective was to determine the prevalence and associated factors of IBS among students at Université des Montagnes (UdM), Cameroon. Methods: A cross-sectional study was conducted from February to May 2024 among 450 students from the Banekane campus, UdM. The sampling method used was cluster sampling. The diagnosis of IBS was based on the Rome IV criteria. Data analysis was performed using SPSS 20.0 software. Associated factors were identified by multivariate logistic regression (p &lt; 0.05). Results: The prevalence of IBS was 17.6%. The IBS-C subtype was predominant (44%). Factors significantly associated with IBS included: regular alcohol consumption (OR = 1.79; 95% CI [1.08-2.9], p = 0.02), magnesium-rich diet (OR = 1.64; 95% CI [1-2.69], p = 0.049), probiotics (OR = 6.64; 95% CI [2.81-15.68], p &lt; 0.001), and soluble fiber intake (OR = 1.46; 95% CI [1-2.69], p = 0.049). Conclusion: IBS is common among UdM students. Specific diet and consumption habits may influence its onset. Nutritional awareness and early management are necessary.
