Sustainability Aspects of Carapa Guianensis Aubl Oil for Antiinflammatory Uses

Objective: The objective of this study is to describe the lipidomic profile of andiroba oil and its socio-economic characteristics focused on the activities of limonoids as an alternative for the generation of nonsteroidal anti- inflammatory drugs in order to relate the generation of products that act on circular and external peripheral inflammation. Theoretical Reference: In this context, andiroba oil (C. guianensis) has a wealth of lipid substances with chemical and socio-economic potential, highlighting its importance for local populations and its potential for sustainable bioeconomics, as this species contains nonsteroidal antiinflammatory drugs from Amazonian oil plants. Method: The methodology adopted includes describing the lipidomic profile of andiroba oil analyzed by GC/MS, using a Zebrom 5HT capillary column specifically designed to analyze both the methyl esters of the various fatty acids and the limonoids and steroids. The bibliographic search was carried out in the CAPES periodicals on the Scopus database, using specific keywords such as andiroba, Carapa, limonoids and antiinflammatories. Three samples of andiroba oil collected in different states were used to compare the lipidomic profiles. Results and Discussion: The results obtained revealed the presence of limonoids 7-desacetyl-7-oxogedunin, 7- oxogedunin, deacetyl gedunin; steroids campesterol, stigmasterol, b-sitosterol and various medium and long chain fatty acids. These results showed valuable information about the presence of limonoids, which have anti-inflammatory properties related to the chemical composition, which can vary with the season, the place of collection and the differences in the extraction processes of this oil. However, there is no total absence of limonoids. Research Implications: This research's practical and theoretical implications emphasize that the active anti-inflammatory principles are found in the unsaponifiable fraction, and therefore, only lipidomic techniques can access these metabolites with more excellent resolution. Thus, with the structural identifications, in silico studies can be carried out to classify their effects on cyclooxygenase enzymes (COXs), specifically COX-1, in circular and external peripheral inflammation. Originality/Value: This study contributes to the literature through the perspective of developing safe anti- inflammatory agents produced from andiroba oil, which is a source of great interest for topical use. This oil stands out as one of the most scientifically studied natural products, being biocompatible and presenting itself as an economical and safe alternative for treating circular and external peripheral inflammations. The relevance and value of this research is evidenced by the fact that limonoids are inhibitors of cyclooxygenases, highlighting the prospect of a new socio-economic aspect.

Characterization of Volatile Organic Compounds and Essential Oil Profile of Pittosporum tobira (Thunb.) W.T. Aiton Cultivated in Tunisia.

The chemical compositions of the essential oils (EOs) of roots, young and old leaves and stems, and flowers of Pittosporum tobira (Thunb.) W.T. Aiton cultivated in Tunisia and of the volatile organic compounds (VOCs) emitted by the powder of each organ were identified. The EOs are extracted from fresh material by hydrodistillation, whereas the VOCs are obtained by head space solid-phase microextraction (HS-SPME) from the powdered dry tissues. Fifty-eight VOCs are identified, while, 105 components are detected for the EOs. The main EOs compounds are α-neoclovene, β-caryophyllene and limonene in roots (22.56, 12.52, and 8.59 %, respectively), viridiflorol in young stems, flowers and young leaves (34.90, 31.60, and 24.60 %, respectively), α-cadinol in young stems and leaves, and flowers (13.80, 10.40, and 9.10 %, respectively), (E)-nerolidol in flowers (13.30 %), and germacrene D in old stems (9.06 %). The major detected VOCs are n-undecane, mainly in young and old leaves (71.40 and 40.90 %, respectively), n-nonane in young leaves and flowers (31.80 and 27.10 %, respectively), α-cubebene in old stems and flowers (22.60 and 15.50 %, respectively), and α-gurjunene and β-gurjunene in roots (14.20 and 12.20 %, respectively). Principal Component Analysis (PCA) carried out on the 26 main volatile compounds (relative content exceeding 6 %) identified both by HS and in the EOs allowed their classification into two groups; compounds specific to roots and those specific to aerial parts. The later are subdivided in to two subgroups; old leaves and stems compounds subgroup, and young leaves and stems, and flowers one. We can notice that the two methods used to extract P. tobira volatile compounds and identify them are complementary. This study defines and differentiates, for the first time, the specific aroma profile of P. tobira from Tunisia. In addition to its ornamental value, all the organs of this species, could be valued as a source of volatile compounds useful in perfume, cosmetics and as food flavoring products.

Controlled drought stress affects rosemary essential oil composition with minimal impact on biomass yield

Rosemary (Salvia rosmarinus Spenn.), an indigenous medicinal and aromatic plant within the Mediterranean region, yields essential oils renowned for their antimicrobial, antioxidant, anticancer, and anti-inflammatory properties. When subjected to various stress conditions, rosemary intensifies the production of essential oils as a defensive mechanism, as occurs when it is subjected to drought stress, making it a potentially interesting crop for marginal dryland areas of Sicily and other Mediterranean areas. Managing rosemary cultivation through controlled drought stress close to the balsamic period may increase the concentration and quality of essential oils and optimize the use of limited resources like water. We conducted two on-farm field experiments in Sicily, southern Italy, to assess the effect of controlled drought stress on rosemary biomass, essential oil yield, and composition. The hypothesis was that drought could improve the concentration of essential oils and modify their chemical composition by increasing valuable aromatic components without negatively impacting crop biomass production, increasing interest in cultivating this species. The experiments were co-designed with farmers selecting dedicated field experiments, cultivars, and crop management. Drought stress was applied during autumn and spring in correspondence with medium-high temperatures and rainwater scarcity. The irrigation input was reduced for three weeks during the balsamic period for each trail. Under stressed conditions, morphometric traits were measured. At harvest time, essential oils were extracted using microwave-assisted extraction. Under the same farm conditions, the canopy height was significantly higher in ‘Barbeque’ than ‘Tuscan Blue cv. (67.3 cm vs. 43.8 cm) This indicates a genotype influence on stress response. Essential oil yield increased by 30 % in plants of Tuscan blue cv. subjected to stress conditions in one of two farms. Additionally, drought stress altered the aromatic profile of the essential oil, resulting in differing percentages of key compounds between stressed and unstressed plants. Generally, there was a higher α-pinene percentage in unstressed plants and higher bornyl-acetate and β-caryophyllene concentrations in drought-stressed plants. In the Scicli farm, α-pinene decreased in response to water stress, while camphene and myrcene increased. Our results summarized that controlled drought stress had a minimal impact on rosemary growth, increasing the percentages of some terpenes in its essential oils. No severe decrease was observed in the synthesis of essential oils, suggesting that rosemary is suitable for marginal soils in many Mediterranean countries to protect soils and diversify crops in farms.

Chemical profile and therapeutic potential of the essential oil and nanoemulsions of Citrus x sp (Tanja Lemon)

The objective of this study was to evaluate the chemical profile and therapeutic potential of the essential oil and nanoemulsions of Citrus x sp (Tanja Lemon). Hydrodistillation was used to extract the essential oil. Gas Chromatography coupled to Mass Spectrometry (GC/MS) was used for the analysis of chemical constituents. The phenolic content (CFT) was analyzed by the Folin-Ciocalteau assay, and flavonoids (CFLT) by complexation with aluminum. The nanoemulsions were formulated by the phase inversion method. The antioxidant activity was evaluated by a hydroxyl radical assay and the anti-inflammatory activity by protein denaturation, and antiarthritic activity by a cyclooxygenase inhibition assay in bovine albumin serum. By means of GC/MS, limonene was identified as the major component (70.25%). The determination of CFT and CFLT quantified 227.645 mg EAT g-1 and 86.57 mg EQ g-1. For antioxidant capacity, nanoemulsions have EC50 values of 9.10-11.28 mg L-1. In anti-inflammatory activity, synergies quantified 4.63-11.03 mg L-1. For the antiarthritic activity, it is noted that among the nine synergies formulated, some manifested excellent antiarthritic activity, with EC50 values of 1.9-1.98 mg L-1. It can be affirmed that the formulations produced from Citrus x sp presented satisfactory results, evidencing the efficacy of their properties.

Identification of Biomarkers Associated with Phyllosticta citricarpa Tolerance.

Citrus black spot (CBS) is a fungal disease caused by Phyllosticta citricarpa Kiely, (McAlpine Van der Aa), with most cultivars being susceptible to infection. Currently, disease control is based on the application of protective fungicides, which is restricted due to resistance, health and environmental concerns. Although using natural products for disease management is gaining momentum, more advances are required. This study obtained the metabolic profiles of the essential oil and cuticular waxes of two citrus cultivars with a varying susceptibility to CBS infection using gas chromatography-mass spectrometry. A multivariate data analysis identified possible biomarker compounds that contributed to the difference in susceptibility between the two cultivars. Several identified biomarkers were tested in vitro for their antifungal properties against P. citricarpa. Two biomarkers, propanoic acid and linalool, were able to completely inhibit pathogen growth at 750 mg/L and 2000 mg/L, respectively.

Unveiling the molecular composition and biological properties of essential oil derived from the leaves of wild Mentha aquatica L.: A comprehensive in vitro and in silico exploration

Abstract The purpose of the current study is to assess the chemical profile, antioxidant, antimicrobial, and insecticide efficacy of essential oil derived from the leaf of Moroccan Mentha aquatica L. (MA-EO) using in vitro and in silico analysis. Using GC-MS/MS analysis, 18 components of MA-EO were identified, including linalool (42.42%), α-elemol (10.45%), α-terpineol (8.07%), linalyl acetate (7.37%), and caryophyllene (4.05%). Additionally, MA-EO has a strong antioxidant capacity with IC50 values of 0.64 ± 0.01 µg/mL using the DPPH assay and 0.167 ± 0.13 µg/mL using the ABTS test. Total antioxidant capacity activities were found to be 188.21 ± 0.31 mg EAA/g, while RP activities were 1.95 ± 0.023. The powerful antibacterial properties of MA-EO were proven to be effective against Escherichia coli and Candida albicans. MA-EO showed insecticidal potential using the fumigation experiment, with an LC50 of 3.33 μL/L in the air after 24 h of exposure. At a dose of 20 µL/mL, MA-EO reduced fertility, fecundity, and emergence of adult C. maculatus. MA-EO had 95% mortality at the same dosage. In silico analysis revealed that the antioxidant activity of MA-EO is linked to γ-eudesmol, while its antibacterial efficacy is associated with phenol, 2,4-di-tert-butyl-, and its antifungal capacity with phenol, 2,4-di-tert-butyl-. MA-EO demonstrates potent bactericidal, fungicidal, and bioinsecticide properties, making it effective for controlling bacteria, fungi, and insect pests in stored grains.

Microbial Decontamination of Cuminum cyminum Seeds Using "Intensification of Vaporization by Decompression to the Vacuum": Effect on Color Parameters and Essential Oil Profile.

Cumin seeds are frequently utilized in herbal infusions and as flavoring agents in home cuisine. Nevertheless, studies have demonstrated that spices are frequently contaminated with pathogenic bacteria, including bacterial spores. The aim of this study was to assess the effectiveness of a new decontamination method called "Intensification of Vaporization by Decompression to the Vacuum" (IVDV) on intentionally contaminated Cuminum cyminum seeds. The study also examined the impact of this treatment on the color and oil profile of the treated samples. The untreated samples were inoculated with Escherichia coli (ATCC 25922) and Salmonella Typhimurium (ATCC 14028) and then subjected to IVDV treatment. Response surface methodology was employed to obtain safe, high-quality cumin seeds presenting a balance between microbial load, color, and oil profile. The optimal IVDV conditions were achieved at a pressure of 3.5 bar and a time of 133.45 s, resulting in typical 4 log reductions observed with 99.99% of Escherichia coli and Salmonella Typhimurium inactivation. The treated spices presented a mild color modification compared to the untreated ones, manifested by a darker shade (decreased L* value), reduced greenness (increased a* value), and heightened yellowness (increased b* value). The GC-MS analysis detected the existence of seven compounds in the treated cumin, with cuminaldehyde being the primary compound (83.79%). Furthermore, the use of IVDV treatment resulted in an increase in the total content of essential oils in some samples, whereby six monoterpenes were identified in the untreated sample compared to seven monoterpenes in IVDV-treated samples. This innovative technology demonstrated high efficacy in decontaminating C. cyminum seeds, improving the extractability of the essential oils while only slightly affecting the color.

Characterization and Antioxidant Activity Assay of Essential Oil Parts of Rosella (Hibiscus sabdariffa L.)

Rosella (Hibiscus sabdariffa L.) is known as a plant whose calyx contain high levels of antioxidant bioactive compounds and good inhibitory power against free radicals. However, other parts of the rosella plant have not yet been utilized for their antioxidant content and activity. The aim of this research is to compare the profiles of essential oils of parts of the rosella plant (seeds, leaves and flower petals) and their antioxidant activity. This research method begins with the process of extracting essential oils using the water-steam distillation method. Furthermore, the profile of the essential oil is known from the results of yield calculations and characterization using the GC-MS instrument. The antioxidant activity was tested using the DPPH method. The yield of essential oils obtained was 0.0107% for seeds, 0.0087% for leaves and 0.0136% for flower petals. GC-MS characterization shows that the most abundant chemical components contained in the essential oils of seeds, leaves, and flower petals are fatty acid compounds (2-propanoic acid, butanoic acid, hexanoic acid) and esters (neopentyl isobutyrate). The results of the antioxidant activity test showed the IC50 value for each essential oil, namely, seeds: 30.15 μg/ml, leaves: 171.27 μg/ml and flower petals: 126.58 μg/ml. The compound characteristics obtained showed the best results for rosella seed essential oil, this was supported by the fairly high antioxidant activity test results IC50 <50 μg/ml. Keywords: Antioxidant activity, Characterization, Essential oils, IC50, Yield.

SummaryIn the present study, the effect of microwave roasting on the total phenolic quantities, antioxidant activities, phenolic constituents, fatty acids and tocopherol amounts of the pistachio kernel and oil was revealed. The moisture, oil, total phenolic amounts and antioxidant capacity value of raw and roasted pistachio nuts were assessed as 31.13%, 28.58%, 34.79 mgGAE/100 g and 0.75%–3.18%, 56.91%, 18.80 mgGAE/100 g and 2.26%, respectively. The raw pistachio nut contains 1.90 gallic acid, 0.22 3,4‐dihydroxybenzoic acid, 0.87 (+)‐catechin, 0.15 1,2‐dihydroxybenzene, 0.15 rutin trihydrate, 0.16 resveratrol, 0.1 quercetin, 0.19 kaempferol and 0.24 mg/100 g isorhamnetin. In addition, microwave‐roasted nuts contained 0.75 gallic acid, 0.62 3,4‐dihydroxybenzoic acid, 0.83 (+)‐catechin, 0.47 1,2‐dihydroxybenzene, 0.21 syringic acid, 0.17 caffeic acid and 0.17 mg/100 g quercetin. The raw and roasted pistachio nut oils contained 74.12% and 71.16% oleic, 13.76% and 15.23% linoleic, 8.16% and 8.92% palmitic and 2.09% and 2.10% stearic acids, respectively. The oil samples of the raw and roasted kernels contained 8.15 and 0.00 α‐tocopherol, 63.78 and 7.60 β‐tocopherol, 8.72 and 7.40 ɣ‐tocopherol and 5.61 and 6.77 mg g−1 δ‐tocopherols, respectively. The total phenolic quantity of the pistachio kernel roasted by microwave decreased significantly. Phenolic compounds of the pistachio kernel showed partial differences depending on microwave heating. Differences were monitored in the fatty acid profiles of Pistachio kernel oils. β‐tocopherol quantity of the oil of the pistachio kernel heated by microwave significantly decreased.

Comparative Study on the Chemical Composition and Biological Activities of the Essential Oils of Lavandula angustifolia and Lavandula x intermedia Cultivated in Lebanon.

The phytochemical profile of essential oils is influenced by genetic and paragenetic factors. In this research, we studied the essential oils of Lavandula angustifolia and Lavandula x intermedia cultivated in Lebanon. The latter is a cross hybrid between Lavandula angustifolia and Lavandula latifolia and is also known as lavandin and Lavandula hybrida. Specifically, the chemical composition and biological activities (antibacterial, antioxidant, anticancer, and hemolytic) of the essential oils were assessed. GC-MS results showed marked differences in the chemical compositions of the oils. For example, linalool was more abundant in L. x intermedia (44.15%) than in L. angustifolia (32%), while an opposite trend was observed for the percentages of 1,8-cineole (8.6% in L. angustifolia and 4.0% in L. x intermedia). FTIR analysis confirmed the richness of both oils in monoterpenes and sesquiterpenes. In terms of antioxidant activity, L. angustifolia essential oil demonstrated significantly better activity (IC50= 5.24 ± 1.20 mg/mL) compared to L. x intermedia oil in the DPPH radical scavenging assay. MTT cell viability assays revealed that L. angustifolia essential oil was a slightly more potent antiproliferative agent than L. x intermedia oil on human colorectal (HCT-116) and human breast (MCF-7) cancer cells. The antibacterial activity of the essential oils was tested against Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Escherichia coli, and Serratia marcescens. Both oils showed good antibacterial activities with MIC values of 0.174 and 0.169 mg/mL for L. angustifolia and L. x intermedia oils, respectively. MBC determinations revealed that the antibacterial activity was bactericidal against all bacteria, except Staphylococcus aureus. Furthermore, both essential oils did not exhibit notable hemolytic activity on red blood cells. Overall, Lebanese L. angustifolia and L. x intermedia essential oils have promising industrial and medicinal values.

The Impact of Beeswax and Glycerol Monolaurate on Camellia Oil Oleogel's Formulation and Application in Food Products.

This study assessed the nutritional profile of camellia oil through its fatty acid composition, highlighting its high oleic acid content (81.4%), followed by linoleic (7.99%) and palmitic acids (7.74%), demonstrating its excellence as an edible oil source. The impact of beeswax (BW) and glycerol monolaurate (GML) on camellia oil oleogels was investigated, revealing that increasing BW or GML concentrations enhanced hardness and springiness, with 10% BW oleogel exhibiting the highest hardness and springiness. FTIR results suggested that the structure of the oleogels was formed by interactions between molecules without altering the chemical composition. In biscuits, 10% BW oleogel provided superior crispness, expansion ratio, texture, and taste, whereas GML imparted a distinct odor. In sausages, no significant differences were observed in color, water retention, and pH between the control and replacement groups; however, the BW group scored higher than the GML group in the sensory evaluation. The findings suggest that the BW oleogel is an effective fat substitute in biscuits and sausages, promoting the application of camellia oil in food products.

Introduction to cultivation Angelica sylvestris var. sylvestris L.: Chemical composition of essential oil and antimicrobial activity

This pioneering study investigates the essential oil content, fruit yield, and antimicrobial activity of Angelica sylvestris. var. sylvestris, comparing specimens from wild populations and cultivated between 2017 and 2022. The research documented fruit yields, which were consistent across the years, ranging from 191.7 to 208.0 g/plant. Essential oils extracted from the fruits were analysed, revealing a content variation between 0.6% and 1.05%. The analysis identified 45 components, predominantly monoterpenes, including α-pinene, α-phellandrene, limonene, β-cymene, isopropyl hexanoate, and β-phellandrene. The chemical profiles of the essential oils from both naturally occurring and cultivated A. sylvestris var. sylvestris were largely similar. The antimicrobial activity of these essential oils was assessed against a range of pathogens, namely Salmonella typhimurium ATCC 14028, Methicillin-resistant Staphylococcus aureus ATCC 43300, Staphylococcus aureus ATCC 25923, Listeria monocytogenes ATCC 19115, and Escherichia coli ATCC 25922. The activity varied according to the harvest year and the type of microorganism. Cultivated A. sylvestris var. sylvestris not only yielded a rich variety of essential oil components but also exhibited enhanced antimicrobial activities compared to its wild counterparts. These findings suggest that cultivation can be a sustainable means of producing high-quality essential oils with potent antimicrobial properties.

Insecticidal, physiological, and biochemical effects of Schinus molle essential oil on the adults of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae)

Rhyzopertha dominica (F.) is considered as a major stored product pest. Conventional insecticides induce adverse effects on the environment. Plant derivative products constitute a promising alternative for pest control. The purpose of our research was to identify the chemical profile of essential oil (EO) extracted from Schinus molle L. (Anacardiaceae) and to evaluate the fumigant and the contact toxicity, and the repellent activity of this oil on adults of Rhyzopertha dominica F. (Coleoptera), a major pest in products that are stored around the world. The effects of this oil were examined on biochemical profile (energy reserves and Proteins), selective biomarkers like acetylcholinesterase (AChE), glutathione S-transferases (GST) and glutathione (GSH), and nucleic acids (DNA and RNA). Digestive enzymes were also investigated. The major chemical compounds identified by the GC-MS were α-phellandrene (16.613%), ß-phellandrene (12.104%), elemol (9.028%) and β-eudesmol (5.872%). Then, we evaluated the repellent activity, and also the effects in nutritional reserves and some biomarkers. This EO exhibited an insecticidal and repellent activity as a function of the exposure time and concentrations. Contact (LC50 at 24 h: 19.99 μL/mL) is the most effective mode of application compared to fumigation (LC50 at 24h: 174.30 μL/L air). S. molle EO was also investigated in digestive enzymes’ activities (α-amylase, lipase, chitinase and protease). Our results revealed a decrease in both α-amylase, lipase, protease and chitinase activities in treated adults compared to controls. In addition, we noticed a neurotoxic activity of S. molle EO traduced by a decrease of AChE. An induction of the detoxification system was observed via a decrease in GSH rate and an increase in GST activity. Moreover, the treatment induces an alteration of biochemical profile of R. dominica adults. Lastly, essential oil was examined on nucleic acids. Results showed an increase in DNA and RNA amount in treated adults when compared with control. Due to their effective source of bioactive compounds, the EO from the studied plant could be used as an alternative strategy for the management of stored product pests.

Maximizing Antioxidant Potential in Picual Virgin Olive Oil: Tailoring Agronomic and Technological Factors with Response Surface Methodology.

Over the past years, a prolonged drought has affected Spain, raising significant concerns across various sectors, especially agriculture. This extended period of dry weather is profoundly affecting the growth and development of olive trees, potentially impacting the quality and quantity of olive oil produced. This study aims to assess the impact of agronomic factors, i.e., olive maturation and irrigation management, as well as the technological factors involved in the production process, on the antioxidant content of Picual virgin olive oil. Mathematical models were developed to maximize the concentration of polyphenols, orthodiphenols, chlorophylls, carotenes, and tocopherols in olive oils. Findings indicate that increasing the malaxation temperature from 20 to 60 °C and reducing the mixing time from 60 to 20 min positively influenced the polyphenol and orthodiphenol content. Although irrigation did not significantly affect the polyphenols, pigments, and α-tocopherol contents, it may enhance the β- and γ-tocopherol content. Optimal conditions for producing antioxidant-enriched virgin olive oils involved olives from rainfed crops, with a moisture index of 3-4, and a 60-min malaxation process at 60 °C. Under these conditions, the total phenol content doubled, pigment content increased fourfold, and α-tocopherol content rose by 15%. These findings provide relevant knowledge to interpret the year-to-year variation in both organoleptic and analytical profiles of virgin olive oils.

Amlou inspired spread: Formulation and characterization of new spread based on Ziziphus lotus L. fruit, argan oil, and honey

This study explores novel applications of combining natural products by integrating Ziziphus lotus L. (Z. lotus), honey, and argan oil to create a product similar to traditional Moroccan Amlou (a mixture of almonds, honey, and argan oil). Five formulations were developed with varying percentages of these three ingredients, alongside two formulations of traditional Amlou. The nutritional value, mineral composition, fatty acid profile, bioactive compounds, and antioxidant activities of the products were analyzed using standard analytical methods such as gas chromatography and spectrophotometry. Additionally, sensory evaluations were conducted to assess consumer preferences. The results showed that the new formulations are rich in oil (45.15–52.24 g/100 g), carbohydrates (40.26–46.81 g/100 g), and protein (3.15–3.92 g/100 g). Mineral analysis revealed significant amounts of potassium (443–578 mg/100 g), calcium (98–124 mg/100 g), phosphorus (50–65 mg/100 g), and magnesium (38–50 mg/100 g). The Z. lotus-based products exhibited higher phenolic content (7–12 mg GAE/g), flavonoids (7.10–10.18 mg QE/g), and stronger antioxidant activities using DPPH radical scavenging activity (3.55–11.14 mg AAE/g) and FRAP (5.39–8.55 mg AAE/g). Moreover, the new product retains the beneficial fatty acid profile of argan oil, with a high content of oleic acid (48 %) and linoleic acid (32 %). Sensory evaluation indicated that the formulation consisting of 45 % Z. lotus powder, 50 % argan oil, and 5 % honey was the most appreciated for taste and texture. These findings suggest that incorporating Z. lotus into traditional Amlou recipes not only enhances nutritional and antioxidant properties but also meets consumer acceptance in terms of flavor and texture.
