Determination of flavonoid and anthocyanin contents, and antioxidant activity of selected Philippine soybean (Glycine max) genotypes

Soybeans contain flavonoids and anthocyanins that are associated with health benefits related to antioxidant activities. In this study, the total flavonoid content (TFC), total anthocyanin content (TAC), and the relative antioxidant activities (AOA) of selected Philippine soybean genotypes were screened in order to select and recommend promising genotypes that may be used for further breeding and varietal development. Using the aluminum trichloride method, the genotypes POP 1-44 (TFC = 0.619 g/100 g), PHL 29272 (TFC = 0.616 g/100 g), and Tiwala 6 (TFC = 0.608 g/100 g) were determined to have the highest calculated TFC values. pH differential and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays distinguished all three black-seeded soybean genotypes PHL 29272 (TAC = 177.010 mg/100 g; AOA = 24.476%), PHL 29502 (TAC = 143.750 mg/100 g; AOA = 25.745%), and PHL 29552 (TAC = 123.572 mg/100 g; AOA = 29.297%) with the highest anthocyanin contents and relative antioxidant activities. Genotype PHL 29272 was consistently found among those with the highest results for the three tests. Significant correlations (α = 0.05) were found between flavonoid content and antioxidant activity (p < 0.0001), and between anthocyanin content and antioxidant activity (p < 0.0001). In conclusion, the study was able to identify genotypes that can be recommended as the most suitable candidates for soybean breeding activities.

Antioxidant activity, total polyphenol, anthocyanin and benzyl-glucosinolate contents in different phenotypes and portion of Japanese Maca (Lepidiummeyenii)

Maca (Lepidium meyenii), mainly grown in Peru, is a traditional herbal medicine that is mostly used to improve sperm motility and serum hormone levels. Maca phenotypes are represented by purple, black, yellow, white, and mixed colors. Recently, a method for Maca cultivation has been established in Japan. Therefore, we determined the effects of different phenotypes and portions on the antioxidant activities and total polyphenols, anthocyanins, and benzyl-glucosinolate contents in Japanese Maca. Purple Maca skin possessed the highest contents of both total polyphenols, antioxidant activity and anthocyanin content in all Macas. Regarding the benzyl-glucosinolate content, white maca had the highest content and was not correlated with antioxidant activity. In the present study, we revealed that purple Maca skin is recommended for high polyphenol content, antioxidant activity, and anthocyanin content. The results of this study will be useful for selecting phenotypes for the improvement of antioxidant activity or hormone balance.

The VvHY5-VvMYB24-VvMYBA1 transcription factor cascade regulates the biosynthesis of anthocyanin in grape

Anthocyanins are important pigments and nutrients in fruits. Red grape is popular because of the high anthocyanin content. Previous studies have identified VvMYBA1 and its homologs as key regulators of fruit color; however, other transcription factors (TFs) that contribute to fruit color remain poorly understood. The present study identified the R2R3-MYB TF VvMYB24, whose gene expression levels were significantly higher in red berries (L51, Vitis vinifera × Vitis labrusca L.) than in green berries (L20, V. vinifera × V. labrusca L.). Overexpression of VvMYB24 in grape calli increased anthocyanin biosynthesis by upregulating the expression of specific structural genes (VvDFR and VvUFGT). Furthermore, VvMYB24 interacted with VvMYBA1 to form a protein complex that additionally increased the expression of VvDFR and VvUFGT. In addition, light-responsive TF VvHY5 could bind to the VvMYB24 promoters to activate its transcription. Taken together, the results reveal a regulatory module, VvHY5-VvMYB24-VvMYBA1, that influences anthocyanin biosynthesis in grape.

Purification and components identification of ‘Ziyan’ anthocyanins

The new tea cultivar ‘Ziyan’ has high anthocyanin content. To explore its potential, the anthocyanin components were separated and prepared using the purple leaves of ‘Ziyan’ as raw materials. A deep eutectic solvent system was prepared for efficient extraction, replacing traditional solvents and achieving higher anthocyanin yield. The extraction parameters were optimized using response surface test and the yield of ‘Ziyan’ anthocyanin reached 5.06 ± 0.04 mg/g (dry weight) at a temperature of 65 °C, solvent moisture content of 29 %, solid-liquid ratio of 1:25 mg/mL and time of 39 min. The DM301 resin was preferred to recover anthocyanins from deep eutectic solvents, resulting in anthocyanin powder with a purity of 6.02 % and a color value of 29.1. It means ‘Ziyan’ anthocyanin has the potential to be developed as a food colorant. The enriched anthocyanins were analyzed using High Performance Liquid Chromatography-Diode Array Detection-Electrospray Tandem-Mass Spectrometry (HPLC-DAD-ESI-MS/MS), identifying 16 anthocyanin derivatives, including 5 acylated components. Petunidin and malvidin were found for the first time in ‘Ziyan’ tea cultivar. This study provided an important basis for the development of ‘Ziyan’ anthocyanins as a natural food and nutraceutical pigment.

Genome-Wide Identification Analysis of GST Gene Family in Wild Blueberry Vaccinium duclouxii and Their Impact on Anthocyanin Accumulation.

Vaccinium duclouxii, a wild blueberry species native to the mountainous regions of southwestern China, is notable for its exceptionally high anthocyanin content, surpassing that of many cultivated varieties and offering significant research potential. Glutathione S-transferases (GSTs) are versatile enzymes crucial for anthocyanin transport in plants. Yet, the GST gene family had not been previously identified in V. duclouxii. This study utilized a genome-wide approach to identify and characterize the GST gene family in V. duclouxii, revealing 88 GST genes grouped into seven distinct subfamilies. This number is significantly higher than that found in closely related species, with these genes distributed across 12 chromosomes and exhibiting gene clustering. A total of 46 members are classified as tandem duplicates. The gene structure of VdGST is relatively conserved among related species, showing closer phylogenetic relations to V. bracteatum and evidence of purifying selection. Transcriptomic analysis and qRT-PCR indicated that VdGSTU22 and VdGSTU38 were highly expressed in flowers, VdGSTU29 in leaves, and VdGSTF11 showed significant expression in ripe and fully mature fruits, paralleling trends seen with anthocyanin accumulation. Subcellular localization identified VdGSTF11 primarily in the plasma membrane, suggesting a potential role in anthocyanin accumulation in V. duclouxii fruits. This study provides a foundational basis for further molecular-level functional analysis of the transport and accumulation of anthocyanins in V. duclouxii, enhancing our understanding of the molecular mechanisms underlying anthocyanin metabolism in this valuable species.

Advances in Blueberry (Vaccinium spp.) In Vitro Culture: A Review

The demand for Vaccinium fruits has skyrocketed due to their nutritional and medicinal properties, notably their high content of phenolic compounds and excellent sensory evaluation. The use of Vaccinium plants and its components as dietary supplements and health ingredients has been on the rise across the world. The attractive fruits contain a high content of anthocyanins and antioxidant compounds. In some popular and valuable cultivars, the conventional propagation methods, exploiting hard or soft wood cuttings, are inefficient. The demand for nursery plants can be fulfilled by micropropagation. This review aims to explore advances in the in vitro culture of Vaccinium plants, focusing on effective disinfection, optimized culture media, and the role of growth regulators in plant development and multiplication. By providing a controlled environment, micropropagation allows the large-scale production of these plants in a short time, ensuring availability throughout the year. Additionally, this technique offers the advantage of studying the effects of abiotic stresses on plants, as well as facilitating research on the production of relevant metabolites. This review seeks to provide an updated overview of the most promising methods and techniques for micropropagation of Vaccinium, thereby contributing to the ongoing development of the blueberry production industry and derivative products.

A Holistic View of the Fate of Berry-Derived Adjuncts throughout Fermentation

Berries and their products can enhance the antioxidant profile, color, and sensory characteristics of beverages, resulting in competitive, value-added products. However, a complete overview of how fermentation affects these compounds is lacking. The American black elderberry, Sambucus canadensis, is an excellent candidate for studying how berry juices are affected during fermentation due to high concentrations of color compounds, anthocyanins, and volatile compounds. Gravity, pH, titratable acidity, total anthocyanins, color, and GC-MS analyses were performed on two varieties of elderberries to examine the physical and chemical qualities of elderberry juice before and after wine fermentation. A commercial product with elderberry adjuncts added post fermentation was also analyzed. The concentration of anthocyanins degraded by ~40% as the color of the elderberry wine shifted from blue to red after fermentation. Products that added elderberries post fermentation did not see the same degradation, however, also did not incorporate the same changes to volatile compounds as observed in the fermented wine. The fermentation industry can use this study’s findings to decide how best to use fruits to improve commercial products.

Management of Secondary Metabolite Synthesis and Biomass in Basil (Ocimum basilicum L.) Microgreens Using Different Continuous-Spectrum LED Lights.

Different LED light spectra (LS) are absorbed by different plant photoreceptors and can control biomass and plant secondary metabolite synthesis. In this study, the effects of continuous-spectrum LED lights (red, blue, white, red + blue, and 12 h blue + 12 h red) on the production value, antioxidant compounds, and biomass of basil (Ocimum basilicum L.) microgreens (Red Rubin, Violeto, and Kapoor cultivars and the Ablagh genotype) were investigated. The results showed significant effects of LS on cultivar (Cv) and the interaction of LS and Cv on the studied traits. The highest quantitys of chlorophyll a, total chlorophyll, and nitrate were obtained in Violeto under blue lighting. Red lighting enhanced starch synthesis in Red Rubin and flavonoids in the Violeto Cv. The highest biomass (4.54 kg m-2) was observed in the Ablagh genotype and the highest carbohydrate synthesis in Violeto Cv in the red + blue treatment. The highest anthocyanin content (26.33 mg 100 g-1 FW) was observed for Red Rubin Cv under 12 h blue + 12 h red light. The greatest antioxidant capacity (83.57% inhibition), the highest levels of phenolic compounds (2027.25 mg GA 100 g-1 FW), vitamin C (405.76 mg 100 g-1 FW), proline, antioxidant potential composite index (APCI), and the greatest production values were obtained for the Ablagh genotype under blue lighting. Taken together, the experiment findings indicate that growing the Ablagh genotype under continuous blue lighting can increase the antioxidant capacity, phenolic compounds, and vitamin C and that this LED light spectrum can be used as a practical method to produce basil microgreens with high nutritional health value.

Strawberry Post-Harvest Anthocyanin Development to Improve the Colour Stability of Strawberry Nectars

Strawberry nectars have increased colour stability when produced from overripe, darker, and redder strawberries, with a high anthocyanin concentration. The post-harvest storage of strawberries has been shown to develop these properties. Nectars are frequently produced from strawberries rejected for fresh sale due to poor colour, which are insufficiently ripe to produce colour-stable nectars. This study investigated post-harvest anthocyanin development in strawberries to improve the colour and colour stability of nectars, which is the first time these developments were studied for beverage production. Strawberries at five ripeness stages were stored at 20 °C for 1 and 2 days prior to nectar production. The anthocyanin content of nectars was determined by a pH-differential method, and the colour stability was tracked for 12 weeks using a consumer Acceptance Factor, derived from CIELAB colour components. The anthocyanin content and colour stability were highly correlated, and both were dependent on ripening, with larger increases observed in under-ripe strawberries, and small to no improvement in overripe samples. Stored partially coloured strawberries produced nectars with equivalent colour stability to non-stored strawberries of normal ripeness. This allowed strawberries that were previously unsuitable for both fresh sale and nectar production to be used as a feedstock for nectar production, reducing food waste.

Natural pre-treatment in raisins production: Effects on quality during storage

BRS Vitoria raisins were produced with a pre-treatment using a natural surfactant, i.e., extra-virgin olive oil (EVOO), to (i) better elucidate its action on the grape surface using scanning electron microscopy; (ii) evaluate its influence on the oleanolic and ursolic acid content of raisins through HPLC-DAD; (iii) assess raisins characteristics during 180-day storage at different temperatures by using physicochemical and microbiological analyses with multivariate-based chemometric methods (MASLT). Grapes which presented adequate physicochemical characteristics and high concentration of anthocyanins originated raisins similar to those reported in the literature. The pre-treatment accelerated the dehydration process (about 26%) mainly because of the non-uniform redistribution of the surface waxy components accompanied by the formation of microholes and cracks. The small amount of EVOO used did not affect the oleanolic acid content in raisins, yet this compound proved to resist drying, which means that there is no loss of wax during the pre-treatment. For both untreated (RW) and pre-treated raisins (RP), the main changes triggered over time were not related to microbiological characteristics. Most of the changes appeared to occur right during drying and not during storage for RW, whereas for RP the physicochemical characteristics that mostly correlated with the storage changes were total monomeric anthocyanins, total acidity, and total sugars; also, they tended to reach an equilibrium and equaled RW at the end of 180 days, especially at 35 °C. These parameters proved to be the main characteristics related to the changes triggered in raisins. For both raisins, sugar crystals were formed in the flesh, but they were not visible to the naked eye or perceived by consumers. The results show that it is highly desirable to have a high-quality product at the beginning of storage, which was possible thanks to the EVOO pre-treatment used.

Natural pigment: Chlorophyll, carotenoid and anthocyanin in the leaves of four ornamental plants

The quantities of some essential plant pigments: chlorophyll, anthocyanin and carotenoid in the leaves of four ornamental plants were assessed. These ornamental plants were: Acalypha wilkesiana, Acalypha hoffmannii, Ficus panda and Gardenia jasminoides-variegata. Standard procedures were followed in the collection, identification and assessment of these plants. Among the plants, A. wilkesiana had the highest content of anthocyanins (2783.10 mg/kg), which could be responsible for the red color of its leaves, while A. hoffmannii had the highest quantity of chlorophyll (932.15 mg/kg) and chlorophyll is responsible for the green colour of plants. Ficus panda which has yellow leaves had the highest carotenoid content (389.40 mg/kg) and the carotenoid pigment is responsible for the yellow colour of plants. Gardenia jasminoides- ariegata which has cream to white leaves had the lowest contents of all three pigments when compared across the plants, but among the pigments, the quantity of carotenoid responsible for the yellow color of plants was the highest (116.70 mg/kg) compared to that of chlorophyll (55.16 mg/kg) and anthocyanin (18.50 mg/kg). The study showed variation in the concentration of pigments in the leaves across the plants and these concentrations are probably responsible for the different colours exhibited by these ornamental plants.

A high-quality chromosome-scale genome assembly of blood orange, an important pigmented sweet orange variety

Blood orange (BO) is a rare red-fleshed sweet orange (SWO) with a high anthocyanin content and is associated with numerous health-related benefits. Here, we reported a high-quality chromosome-scale genome assembly for Neixiu (NX) BO, reaching 336.63 Mb in length with contig and scaffold N50 values of 30.6 Mb. Furthermore, 96% of the assembled sequences were successfully anchored to 9 pseudo-chromosomes. The genome assembly also revealed the presence of 37.87% transposon elements and 7.64% tandem repeats, and the annotation of 30,395 protein-coding genes. A high level of genome synteny was observed between BO and SWO, further supporting their genetic similarity. The speciation event that gave rise to the Citrus species predated the duplication event found within them. The genome-wide variation between NX and SWO was also compared. This first high-quality BO genome will serve as a fundamental basis for future studies on functional genomics and genome evolution.

Effect of Maltodextrin Concentrations and Drying Temperature on the Physico-chemical Characteristics and Color Measurements of Butterfly Pea Flowers (Clitoria ternatea L) Powder

Butterfly pea flower (Clitoria ternatea L.) is a tropical plant that is rich in bioactive compounds, especially anthocyanins which are useful as natural dyes and antioxidant compounds. The bioactive compounds of butterfly pea flowers are unstable due to environmental influences, especially temperature, oxygen, light and acidity. In order to improve the stability of bioactive compounds, especially anthocyanin compounds in powder form, it is necessary to utilize encapsulation technology using coating materials. The aim of this research was to determine the effect of maltodextrin concentration and drying temperature on the physico-chemical characteristics and color measurements of encapsulated butterfly pea flower extract. The research method used was a factorial design prepared using a randomized block design consisting of 2 factors. Factor I (maltodextrin concentration) consisted of 3 levels, namely (10%, 20%, and 30%) while factor II (drying temperature) consisted of 3 levels (70ºC, 80ºC, and 90ºC), with 3 repetitions. The observation variables are: a) antioxidant activity, b) anthocyanin content, c) water content, d) dissolution time, e) color properties (L*, a*, and b*). Based on general research results, a maltodextrin concentration of 10% and a drying temperature of 70ºC showed the best results based on antioxidant activity rate and the highest anthocyanin content (51.47% and 47.36mg/g), as well as color measurements with the lowest L* value = 52, highest a* value = +2.6, and highest b* = -11.16. Except for powder solubility, a maltodextrin concentration of 30% and a drying temperature of 90ºC resulted in the fastest solubility time (16.67 seconds). For water content, all treatments were still in accordance with spice standards in Indonesia and standards issued by the USDA.

Effects of Methyl Jasmonate on Quality and Phytochemical Contents of Postharvest ‘Kamphaeng Saen 42’ Mulberry Fruit

The ‘Kamphaeng Saen 42’ mulberry fruit is consumed fresh and is rich in nutrients. However, it has a short shelf life of only 1-2 days under room temperature conditions. This research aimed to study the effects of methyl jasmonate (MeJA) on quality and phytochemical content of postharvest 'Kamphaeng Saen 42' mulberry fruit. The fruits were fumigated with 0 (control), 10, and 20 µmolL-1 MeJA at 20 °C for 6 h, then stored at 10 ± 2 °C, 90 ± 2 relative humidity (RH) for 8 days. The results showed that fruits treated with 10 µmolL-1 MeJA were most effective in retarding weight loss, and all treated fruits tended to exhibit reduced spoilage compared to the control, although the differences were not significant. Additionally, fruit treated with 10 µmolL-1MeJA showed a significant increase in phytochemicals and antioxidant activities; their total ascorbic acid and total phenolic contents were higher than in other treatments (p<0.01). Fruit treated with 20 µmolL-1 MeJA had a significantly increased skin color change (p< 0.05), resulting in the highest anthocyanin content. These results suggested that MeJA treatment effectively maintains quality and boosts phytochemical content in postharvest 'Kamphaeng saen 42' mulberry fruit.

Analyzing Tear Fluid Composition by Synchronous Fluorescence for Diagnosing Dry Eye Disease and the Role of Phytotherapy Intervention

Purpose Tear fluid gained attention as a representative biological fluid. Its simple and non-invasive collection methods as well as richness of candidate biomarkers made it a potential diagnostic tool for different diseases such as dry eye. Synchronous fluorescence spectroscopy is a highly sensitive analytical tool that results in narrowing and enhanced peak resolution, and has a potential role in disease diagnosis, biomarker identification, and therapeutic monitoring. We applied synchronous fluorescence spectroscopy to monitor variations of tear fluid composition during the development of dry eye disease and to evaluate the potential effects of phytotherapy. Methods Dry eye model was induced in Chinchilla rabbits by instillation of 1% atropine sulfate ophthalmic solution. Then, the tear fluid was collected at 3, 7, and 14 days and subjected to synchronous fluorescence spectroscopy. Phytotherapy was achieved by topical instillation of 20 µl of water extracts of pomegranate peel or green tea powders. Results The fluorescence results revealed changes in the structure of tear fluid over time and the eye is subjected to toxification due to oxidative stress. In addition, dry eye disease was found to affect the metabolic/energetic state of the eye. On the other hand, phytotherapy led to enhancement of the metabolic/biosynthesis state due to activation of flavin adenine dinucleotide-associated proteins. Conclusion There was change in the electrical conductivity of tear fluid proteins. In the case of dry eyes, they became electrical insulators, while in the case of treatment with extracts, their electrical conductivity properties improved. The effects of phytotherapy can be related to the high content of ellagic acid and anthocyanin of pomegranate extract, while in green tea, they are related to catechins and phenolic compounds.

Exploring Leaf Anthocyanin Concentrations and Light Effects on Lettuce Growth

Anthocyanins are secondary metabolites classified as water-soluble, non-photosynthetic pigments with the potential ability to shield chloroplasts from excess light energy. This study investigated the morphological and physiological responses of six lettuce (Lactuca sativa) cultivars with different leaf anthocyanin contents grown in a greenhouse under different supplemental photosynthetic photon flux densities (PPFD). Cultivars ‘Cherokee’, ‘Teodore’, ‘Rex’, and ‘Rouxai’ decreased in specific leaf area with increasing PPFD, respectively. We observed that growth in cultivars with higher leaf anthocyanin content (‘Cherokee’ and ‘Rouxai’) increased with increasing PPFD. Light use efficiency (LUE) is an important physiological parameter affecting biomass accumulation, and cultivars ‘Cherokee’, ‘Rex’, ‘Teodore’, and ‘Rouxai’ had the highest LUE and shoot weight. We found that red lettuce varieties, especially ‘Cherokee’ and ‘Rouxai’, showed increased shoot dry weight as light intensity increased. Interestingly, these varieties also had the highest anthocyanin levels in their leaves. This suggests that higher anthocyanin content might contribute to the increased shoot dry weight under higher light intensity, although this was mainly evident in ‘Cherokee’.

Haplotype-resolved chromosomal-level genome assembly reveals regulatory variations in mulberry fruit anthocyanin content.

Understanding the intricate regulatory mechanisms underlying the anthocyanin content (AC) in fruits and vegetables is crucial for advanced biotechnological customization. In this study, we generated high-quality haplotype-resolved genome assemblies for two mulberry cultivars: the high-AC 'Zhongsang5801' (ZS5801) and the low-AC 'Zhenzhubai' (ZZB). Additionally, we conducted a comprehensive analysis of genes associated with AC production. Through genome-wide association studies (GWAS) on 112 mulberry fruits, we identified MaVHAG3, which encodes a vacuolar-type H+-ATPase G3 subunit, as a key gene linked to purple pigmentation. To gain deeper insights into the genetic and molecular processes underlying high AC, we compared the genomes of ZS5801 and ZZB, along with fruit transcriptome data across five developmental stages, and quantified the accumulation of metabolic substances. Compared to ZZB, ZS5801 exhibited significantly more differentially expressed genes (DEGs) related to anthocyanin metabolism and higher levels of anthocyanins and flavonoids. Comparative analyses revealed expansions and contractions in the flavonol synthase (FLS) and dihydroflavonol 4-reductase (DFR) genes, resulting in altered carbon flow. Co-expression analysis demonstrated that ZS5801 displayed more significant alterations in genes involved in late-stage AC regulation compared to ZZB, particularly during the phase stage. In summary, our findings provide valuable insights into the regulation of mulberry fruit AC, offering genetic resources to enhance cultivars with higher AC traits.

Bio-pigment extraction from blue-color flowering landscape ornamentals

The plants used in landscaping, which typically grow in the wild, along roads, or on homestead land, produce flowers in different shades of colors, from which pigments in other hues can be derived. In this study, six aqueous extraction techniques were used to extract pigments from three plant species, Lagerstroemia sp., Clitoria sp., and Eichhorniacrassipesthat, which produce blue-colored flowers. This study aimed to standardize the processes for extracting pigments from flowers of naturally occurring plant species, identify potential sources of blue-colored natural pigments and assess the durability and quality of the pigments. Clitoria sp. had the highest anthocyanin concentration (64.44 mg/l) when extracted with microwave assistance.

Response and Adaptive Mechanism of Flavonoids in Pigmented Potatoes to Different Altitudes.

Altitude is an important ecological factor affecting plant physiology and ecology, material metabolism and gene expression. Tuber color changes were observed in purple and red potatoes growing at four different elevations ranging from 1800±50 to 3300±50 meters in the Tiger Leaping Gorge area of Yunnan Province. The results showed that the TPC, TFC, TAC and biological yield of anthocyanin increased with increasing altitude until 2800 ± 50 m, and the highest anthocyanin contents were detected in the purple potato Huaxinyangyu and the red potato Jianchuanhong at the flowering stage and budding stage, respectively. Combined transcriptomic and metabolomic analyses revealed that the content and diversity of flavonoids are associated with gene expression via the promotion of propane metabolism to improve potato adaptation to different altitudes. These results provide a foundation for understanding the coloring mechanism and creating new potato germplasms with high resistance and good quality via genetic manipulation.

Tablets containing açaí (Euterpe spp.) dried extract for dietary supplementation: A study of functional properties

Açaí is a very popular functional food in the Amazon due to its nutritional properties, its high caloric value, and its high content of anthocyanins and phenolic compounds, which mainly confers antioxidant and anti-inflammatory activities. Thus, this study aimed at the development of immediate-release tablets containing açaí dried extract by direct compression. The extract was subjected to physical evaluation of the powder, quantification of total polyphenol (TP) content (mg EAG/g), total anthocyanin content (mg C3G/100 g), cyanidin-3-rutinoside marker (µg C3R/g) by LC-MS, obtention of the tablet, and their physical-mechanical evaluation. Açaí dried extract showed spherical shape particles, with smooth and rough surfaces and heterogeneous sizes, which are characteristic of dried powders when obtained by spray drying. In addition, the extract presented TP content (23.307± 2.190 mg EAG/g), total anthocyanins (10.52 mg C3G/100 g), and cyanidin-3-rutinoside (42 µg C3R/g). Tablets had good mechanical properties, good thermal stability under 200°C, and 3.65 µg C3R/g of cyanidin-3-rutinoside content per tablet unit. The results obtained in this study showed the possibility of obtaining tablets containing açaí dried extract with good mechanical properties and antioxidant activity aiming its use as a dietary supplement.
