Lotus ( Nelumbo nucifera, G.) is a perennial aquatic plant, which is utilized for a variety of therapeutic and food applications. Muffins are a kind of baking product that is typically consumed for breakfast or as a snack. Currently, many baked goods in the market use fat replacers to lower the overall fat content, while conserving consumer approval. The study's objectives were to produce low-fat muffins and to characterize the types of quality changes that occurred in the muffins. Lotus rhizome was sliced, dried and converted into powder, which used as fat substitute in muffins, at 0, 5, 10, 15 and 20% replacement levels, with names as M 0 , M 1 , M 2 , M 3 and M 4 , respectively. Composite flours having these proportions of lotus Rhizome Powder (LRP) were analyzed for proximate and rheological parameters. Increasing levels of LRP caused increased water absorption and dough development time of the composite flours. Proximate analyses of muffins showed highest value of moisture (25.05%), ash (2.43%), fiber (0.99%), protein (11.89%) and NFE (58.45%) in M 4 . Whereas, fat content and energy value were significantly reduced in M 4 , as highest fat was found to be in M 0 (36.65%) and highest calories in M 0 (576.5 kcal), which were significantly reduced to 26.24% and 514.5 kcal, respectively in M 4 . High yeast and mold count was of M 0 at first day as 98 CFU/g, which was increased to 129 CFU/g at day 7, whereas M 4 presented this count to be 44 CFU/g at day one, which was increased to 70.33 CFU/g at day 7. Texture analysis showed softest texture of M 4 as firmness value was 1887 g, which was significantly high in M 0 as 2285 g. The research revealed that M 3 best performed out of all treatments as 15% replacement of fat with LRP significantly improved the rheological properties of the flour, ash and fiber content were high, whereas fat contents were significantly low in these muffins. Textural and sensory analysis also supported the M 3 due to softer texture and significantly high color, appearance, flavor, and overall acceptability scores. From the results of this study, it could be concluded that a 15% replacement of shortenings with LRP could be considered as optimum for developing good quality baked muffins. Graphical

Four powders of Forsythia suspensa leaf were prepared by coarse grinding and subsequent ball milling . The effects of particle size on the physicochemical and antioxidant properties of the powders were evaluated. The results showed that the particle size of the powder decreased from 107.99 to 29.20 μm by ball milling for 5 h. In addition, the ball-milled powders had substantial advantages in water holding, solubility and swelling capacities. Thus, the ball-milled powders had a better dissolution of phenolic, flavonoid , and polysaccharide components (25.45, 1.99 and 44.19 mg/g of powder for 5 h of ball milling), ultimately resulting in a superior antioxidant activity (maximum reductions of 14.96% and 19.20% for DPPH and ABTS radicals, respectively). The FTIR analysis showed that the structure of the active ingredients remained intact after ball milling. In conclusion, ball milling is a promising technique for preparing Forsythia suspensa leaf powder with improved physicochemical and biological properties.

Folate is an essential vitamin for the human body and must be obtained exogenously. It is recognized that some microorganisms are capable of producing folates during growth, revealing possibilities for innovations of natural folate biofortified foods. The aim of this study was to identify potential folate-producing strains to enhance folate content in fermented Moringa oleifera leaves powder (MOLP). Although most of the tested strains exhibited folate production, there were significant differences among them in terms of both quantity and distribution, whether intracellular or extracellular. 10 strains with potential for folate production were chosen for enhancing the folate content of MOLP. The two most promising strains, Lactiplantibacillus sp. LP1 and Saccharomyces cerevisiae Y-J-1, demonstrated high folate levels up to 1940 and 2115 μg/100 g dry matter, respectively. These levels were 1.6 and 1.8-fold the initial value in MOLP. Additionally, the fermentation of MOLP not only enhanced its nutritional quality but also preserved its significant bioactivity. This study provides the initial understanding of how selected microorganisms can naturally enrich folates in fermented MOLP, presenting an alternative solution to address the widespread issue of folate deficiency while promoting human health.

Developing sustainable, low‐carbon technologies to remove antibiotics from wastewater is vital to reduce ecological and health risks and meet dual carbon targets of peaking and neutrality. In this work, a surface-modified Platanus leaf powder (PLP) adsorbent was fabricated via metal-phenolic network (MPN) assembly. At pH 8, Fe(III)-tannic acid (TA) coordinated MPNs self-assembled to generate a supramolecular nanocoating on PLP, yielding the Fe(III)-Tannic networks on PLP (FTN@PLP) composite. Batch adsorption studies demonstrated an impressive maximum tetracycline (TC) uptake of 118.9 mg/g. The removal performance was systematically investigated by varying the Fe/TA ratio, pH, adsorbent dosage, initial concentration, coexisting ions, and humic acid. Adsorption kinetics, isotherm modeling and characterization study revealed that TC uptake was driven by a cooperative mechanism involving electrostatic attraction, Fe 3+ complexation, and hydrogen bonding. Additionally, FTN@PLP effectively removed representative dye pollutants. When evaluated for tetracycline (TC) removal over five successive adsorption–desorption cycles, the adsorbent maintained regeneration efficiencies exceeding 80 %. Life cycle assessment (LCA) indicated that the preparation route has a low environmental impact; leveraging plant polyphenols and biomass waste provides a promising pathway for carbon-reduction and biomass valorization. This novel strategy integrates material innovation with stewardship, providing a solution for wastewater treatment under low-carbon guidelines.

The hybrid plant edible grass (Rumex patientiaL. ×Rumex tianschanicusA. LOS), a member of the Rumex genus, presents a novel food source with a protein content of approximately 30–40%. By incorporating non-traditional feed sources, such as edible grass leaf powder (EGLP), into broiler production, costs could be reduced. The experimental subjects of this study were Arbor Acres (AA) broilers. A total of 300 newly hatched broilers were randomly divided into to five groups, with each group consisting of six cages, housing 10 birds per cage. The control group was fed a basal diet composed of maize and soybean meal. In the experimental groups, varying percentages (3%, 6%, 9%, and 12%) of EGLP were substituted for the corn–soybean meal in the basal diet. In the diet, for days 1–21, the corn content was reduced from 1.90% to 8.20%, and the soybean meal content was lowered from 1.50% to 6.00%. Similarly, in the diet, for days 22–42, the corn content was decreased from 1.17% to 7.00%, while the soybean meal content was reduced by 1.50% to 6.00%. The experiment lasted 42 days and was divided into two phases: the brooding phase (days 1 to 21) and the finishing phase (days 22 to 42). The results show that substituting 3% and 6% EGLP for corn and soybean meal significantly increased the average daily gain (ADG) during the brooding period compared to the control group (p< 0.01). Additionally, the group with a 3% substitution rate exhibited a significant increase in the average daily feed intake (ADFI) during the brooding phase (p< 0.01). Throughout the 42-day experiment, substituting 3% and 6% of EGLP for maize and soybean meal did not significantly affect the overall growth performance of broilers (p> 0.05). However, a 6% supplementation notably reduced the feed conversion ratio (FCR) (p< 0.01). Both the 3% (EG3) EGLP and 6% (EG6) EGLP replacement meals significantly enhanced the antioxidant capacity of broiler chickens, as indicated by the increased levels of the total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) (p< 0.01). Additionally, broilers supplemented with 3–12% showed a marked increase in cecal short-chain fatty acids (SCFAs) compared to the control group (p< 0.01). The 3% EGLP replacement diet also significantly boosted the prevalence ofLactobacillusin the cecum (p< 0.01). Furthermore, after EGLP supplementation, there was a higher abundance of SCFA-metabolizing bacteria, particularlyAlistipesandChristensenellaceae_R-7, compared to pre-treatment (p< 0.05). The prevalence ofClostridiumwas significantly greater in the groups receiving 9% and 12% EGLP (p< 0.05), whileButyrivibriolevels were notably higher after supplementation with 12% EGLP (p< 0.05).
