This study aimed to investigate the effectiveness of ozonated water in the sanitation and postharvest quality of acerola fruits. The experiment comprised seven treatments: a control group with untreated fruits, three different durations of exposure to ozone microbubbles (20, 40, and 60 min), and three different durations of exposure to ozone-free microbubbles (20, 40, and 60 min). Acerola fruits were stored in a refrigerated environment below 5 °C at 87% relative humidity. Microbiological and quality analyses were performed immediately after ozonation on day 0 and then on storage days 3, 6, and 9. The quality parameters assessed included the fresh mass loss percentage, firmness, soluble solid content, pH, total titratable acidity, vitamin C, color, total phenolic compounds, and total antioxidant activity. The use of ozonated water was found to effectively maintain the firmness of the acerolas, regardless of the exposure duration. Changes were observed on the surface of fruits treated with ozone microbubbles, especially when 60 min of exposure was adopted. Treating acerolas with ozone microbubbles for 20 min proved to be the best condition for inactivating bacteria and fungi and preserving the vitamin C, pH, total titratable acidity, total phenolic compounds, and total antioxidant activity of the fruits throughout storage. In conclusion, ozonated water is a promising technology for sanitizing and preserving the postharvest quality of acerola. Full article

Background/Objectives: Ultraviolet B (UV-B) is a significant risk factor for skin damage, as it induces cyclobutane pyrimidine dimers (CPD), which suppress DNA replication and transcription. Photolyase (PHR) is a blue light-dependent enzyme that repairs DNA damage caused by UV irradiation. While it is absent in human, it plays a crucial role in repairing CPD in other organisms. Acerola (Malpighia emarginata DC), a fruit with high antioxidant content, is widely consumed for health benefits. This study aimed to identify a novel PHR in acerola and evaluate its photorepair activity. Methods: Using RNA-seq data, we cloned the full-length sequence of the acerola PHR gene and constructed an expression vector. A stable transfected HEK293 cell line (HEK293/acPHR) was established. CPD repair activity was analyzed under blue light in these cells, as well as in normal human dermal fibroblasts (NHDFs) supplemented with extracellular vesicles (EVs) from HEK293/acPHR cells and extracellular vesicle-like nanoparticles derived from acerola extract. Results: Blue light-dependent CPD reduction was observed in HEK293/acPHR cells compared to control cells following UV-B irradiation. Additionally, CPD repair activity was demonstrated in NHDFs and HEK293 cells treated with EVs from HEK293/acPHR cells and nanoparticles from acerola extract. Conclusions: Acerola-derived PHR exhibits the potential to repair UV-induced DNA damage in human cells. Furthermore, EV-mediated delivery of PHR provides a promising avenue for extending photorepair capabilities to other cells. These findings highlight the potential applications of acerola PHR in the prevention and treatment of UV-induced skin damage and related conditions. Full article

Acerola fruit has great nutritional and economic relevance; however, its rapid degradation hinders commercialization. The use of coatings reduces post-harvest biochemical modifications and provides physical and biological protection for vegetables such as acerola. This study developed and characterized an edible coating made from pearl pineapple peel flour (PPPF) and yam starch (YS) to preserve the quality standards of acerola fruits during storage at room temperature and under refrigeration. The edible coating, composed of 4 g of PPPF, 3 g of starch, and 10% glycerol, presented excellent moisture content (11%), light tone (L* 83.68), and opacity (45%), resistance to traction of 27.77 Mpa, elastic modulus of 1.38 Mpa, and elongation percentage of 20%. The total phenolic content of the coating was 278.68 ± 0.45 mg GAE/g and the antioxidant activity by DPPH was 28.85 ± 0.27%. The quality parameters of acerolas were evaluated with three treatments: T1—uncoated fruits; T2—fruits coated with 1% glycerol; and T3—fruits coated with PPPF-YS. The T3 treatment reduced the weight loss of stored acerolas, maintaining the light and bright color of the fruits, and delayed the decrease in soluble solids, especially in refrigerated fruits. Therefore, edible coatings based on pineapple flour and yam starch are effective technologies for controlling the physical and physicochemical parameters of acerolas during storage, benefiting the post-harvest quality of this fruit.

Acerola (Malpighia emarginata DC.) is a sub-tropical and tropical fruit renowned for its high levels of vitamin C and phenolic compounds, which offer health benefits. This study aimed to optimize the spray drying process by determining the inlet and outlet temperatures using response surface methodology (RSM) with the central composite design. Additionally, it aimed to evaluate the release kinetics in the hydrophilic food simulation environment and the stability of the resulting powder under various storage temperatures. The RSM method determined the optimal inlet and outlet temperatures as 157 °C and 91 °C, respectively. High-accuracy prediction equations (R2 ≥ 0.88) were developed for moisture content (3.02%), process yield (91.15%), and the encapsulation yield of total polyphenol content (61.44%), total flavonoid content (37.42%), and vitamin C (27.19%), with a predicted monolayer moisture content below 4.01%, according to the BET equation. The powder exhibited good dissolution characteristics in the acidic hydrophilic food simulation environment and showed greater stability when stored at 10 °C for 30 days, compared to storage at 35 °C and 45 °C.

This study evaluated the effects of acerola and guava fruit processing co-products fermented with probiotic Lactobacillus acidophilus LA-05 and Lacticaseibacillus paracasei L-10 on the abundance of different intestinal bacterial groups and microbial metabolic activity during 48 h of in vitro fecal fermentation. Digested fermented fruit co-products increased the relative abundance of beneficial bacterial groups while overall decreasing or maintaining the relative abundance of non-beneficial bacterial groups, suggesting selective stimulatory effects on beneficial bacterial intestinal populations. The fermented co-products stimulated microbial metabolic activity due to decreased pH, sugar consumption, short-chain fatty acid production, phenolic compound and metabolic profile alteration, and high antioxidant capacity during fecal fermentation. Acerola and guava co-products have high nutritional value and bioactive compounds whose fermentation with probiotics improves their potential functionalities. The results show that fermented fruit co-products could induce beneficial changes in the relative abundance of several bacterial groups as well as in the metabolic activity of the human intestinal microbiota. These results highlight their potential as novel and circular candidates for use as synbiotic ingredients. Full article

Guava, pitanga and acerola are known for their vitamin content and high levels of bioactive compounds. Thus, the preparation of combinations of these fruits comprises a blend with high nutraceutical potential, yielding a strong and attractive pigmentation material. In this study, the influence of different proportions of maltodextrin on the lyophilization of a blend of guava, acerola and pitanga was evaluated considering not only the physicochemical, physical and colorimetric parameters but also the bioactive compounds in the obtained powders. The blend was formulated from the mixture and homogenization of the three pulps in a ratio of 1:1:1 (m/m), then maltodextrin was added to the blend, resulting in four formulations: blend without adjuvant (BL0), and the others containing 10% (BL10), 20% (BL20) and 30% (BL30) maltodextrin. The formulations were lyophilized and disintegrated to obtain powders. The powders were characterized in terms of water content, water activity, pH, total titratable acidity, ash, total and reducing sugars, ascorbic acid, total phenolic content, flavonoids, anthocyanins, carotenoids, lycopene, color parameters, Hausner factor, Carr index, angle of repose, solubility, wettability and porosity. All evaluated powders showed high levels of bioactive compounds and the increase in maltodextrin concentration promoted positive effects, such as reductions in water content, water activity and porosity and improved flow, cohesiveness and solubility characteristics.

Acerola (Malpighia emarginata DC.) is a tropical fruit with a vibrant red color attributed to anthocyanins, natural pigments, with several applications in the food, nutraceutical, and cosmetic industries. Therefore, the suitability of acerola fruit waste for producing anthocyanin colorants by dynamic maceration was investigated. The extraction process was optimized by combining the factors time (2–90 min), temperature (20–90 °C), and ethanol percentage (0–100%) in a central composite rotatable design (CCRD) coupled with response surface methodology (RSM). The extraction yield determined by a gravimetric method and the levels of cyanidin-O-deoxyhexoside and pelargonidin-O-deoxyhexoside anthocyanins quantified in the 20 run extracts by HPLC-DAD were used as dependent variables. After fitting the experimental data to a quadratic equation, the obtained statistically valid predictive models were used to determine optimal macerating conditions. Under global settings (25 min processing at 41 °C with 12% ethanol), the extraction yielded 57.1% (w/w) and each gram of extract contained 2.54 mg of anthocyanins. Overall, this study highlights the renewable potential of acerola fruit waste for obtaining natural anthocyanin extracts that could represent a sustainable alternative to artificial colorants used in food and other products.

Acerola is considered a superfruit, rich in vitamin C, phenolics, and carotenoids, and having a high antioxidant capacity. However, it is poor in oligosaccharides. Ultrasound technology can improve the bioavailability of several bioactive compounds, improving the nutritional content of several fruit juices. This work evaluated the use of ultrasound processing on acerola juice supplemented with fructooligosaccharides (FOS; 1% w/w) and its effects on the availability of vitamins, carotenoids, and phenolic content. The antioxidant capacity of the juice was correlated with its bioactive contents. The study evaluated the effects of important sonication parameters, such as ultrasonic power density, processing time, and processing temperature. The application of ultrasound was efficient in increasing the availability of some vitamins. As a result, ultrasound application increased the availability of vitamins B1, B3, B5, C, carotenoids, and phenolic compounds. This improvement increased the antioxidant activity of the FOS-enriched acerola juice. Full article

Foam mat drying is a widely used technique for liquid products because it has a number of advantages; however, for an efficient process, the choice of additives and temperatures is extremely important. The objective of this study was to evaluate the effect of additives and drying temperatures on the powders obtained from the blend of tropical red fruits, such as acerola, guava, and pitanga. The foam formulations were prepared by mixing the pulps of the three fruits in equal proportions (1:1:1), all added with 6% albumin and 1% stabilizing agent: E1, gum Arabic; E2, guar gum; E3, gelatin. The combinations were subjected to beating, and subsequently, they were dried in an oven with forced air circulation at four temperatures (50 to 80 °C), with a mat thickness of 0.5 cm. The obtained powders showed low levels of water and water activity and high levels of bioactive compounds, colors with a predominance of yellow, intermediate cohesiveness, poor fluidity, and solubility above 50%. The best temperature for obtaining the powders was 60 °C. The formulation that produced the best results for the production of the tropical red fruit blend powder was the combination of albumin and gelatin. Full article

The combination of fruit pulps from different species, in addition to multiplying the offer of flavors, aromas and textures, favors the nutritional spectrum and the diversity of bioactive principles. The objective was to evaluate and compare the physicochemical characteristics, bioactive compounds, profile of phenolic compounds and in vitro antioxidant activity of pulps of three species of tropical red fruits (acerola, guava and pitanga) and of the blend produced from the combination. The pulps showed significant values of bioactive compounds, with emphasis on acerola, which had the highest levels in all parameters, except for lycopene, with the highest content in pitanga pulp. Nineteen phenolic compounds were identified, being phenolic acids, flavanols, anthocyanin and stilbene; of these, eighteen were quantified in acerola, nine in guava, twelve in pitanga and fourteen in the blend. The blend combined positive characteristics conferred by the individual pulps, with low pH favorable for conservation, high levels of total soluble solids and sugars, greater diversity of phenolic compounds and antioxidant activity close to that of acerola pulp. Pearson’s correlation between antioxidant activity and ascorbic acid content, total phenolic compounds, flavonoids, anthocyanins and carotenoids for the samples were positive, indicating their use as a source of bioactive compounds.

This study aimed to evaluate the effect of fertilization combinations of nitrogen (N), phosphorus (P), and potassium (K) on the production and quality of West Indian cherry grown under salt stress in the second year of production. The study was conducted in a protected environment following a randomized block design with treatments distributed in a 2 × 10 factorial arrangement referring to two levels of electrical conductivity of irrigation water (0.6 and 4.0 dS m−1) and 10 NPK fertilization combinations (80-100-100; 100-100-100; 120-100-100; 140-100-100; 100-80-100; 100-120-100; 100-140-100; 100-100-80; 100-100-120 and 100-100-140% of the recommendation in the second year of production), with three replicates and one plant per lysimeter. Production and post-harvest variables evaluated were: the total fruit weight, total number of fruits, mean fruit weight, the polar and equatorial diameter, total soluble solids, pulp pH, titratable acidity, maturity ratio, vitamin C, reducing sugars, total phenolic compounds, total anthocyanins, and flavonoids. The results indicate that irrigation with water having a salinity of 4.0 dS m−1 negatively affected all production variables. The interaction between the ECw of 0.6 dS m−1 and the 100-80-120 NPK fertilization combination increased the total number of fruits and the total fruit weight of West Indian cherry. Full article

With the increased demand for sustainable, hypoallergenic products, plant surfactants are a promising, eco-friendly option for cleaning products due to their low toxicity or even the absence of toxicity. In the present study, surfactant-rich extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata were assessed for their stability, antioxidant capacity, toxic potential, and cleaning potential in shampoo formulations. The surfactants in the extracts were isolated and characterized by NMR, UV-Vis, and FTIR spectroscopy. The results demonstrated that the extracts remained stable within the temperature and pH ranges tested. The antioxidant properties were also determined. In the analysis of irritation potential, G. max and C. quinoa exhibited low toxicity and no toxicity, respectively. The cleaning potential analysis confirmed that the extracts could be used as primary surfactants. Seven shampoo formulations were developed, which showed potential to reduce surface tension to the range of 27.1–31.7 mN/m and interfacial tension to the range of 5.4–7.3 mN/m. The wettability, percentage of solids, density, pH, and dirt dispersion of the formulas were within standard ranges, and the sebum removal capacity of the seven formulations was similar to or even better than that of a commercial shampoo.

Acerola (Malpighia emarginata D.C.) is an exotic fruit with high agro-industrial potential due to its high content of ascorbic acid (AA), phenolic compounds, and carotenoid pigments. Acerola fruit is processed into concentrated juice or powder to be incorporated into food supplements. The ascorbic acid content of concentrated juice or powders must be controlled and well assessed. Therefore, the development of optimal methods and procedures for the rapid and accurate determination of the ascorbic acid content in juice concentrate and juice powder remains of considerable commercial interest. NMR spectroscopy is currently a powerful spectroscopic tool for the qualitative and quantitative analysis of molecules of all types and sizes. Firstly, this article presents the NMR-based metabolomic profiling of acerola juice and concentrate powder to describe and compare their composition. Thirty-six metabolites were identified. The AA over choline ratio and the NMR metabolomic profiles could be used for authentication in the future. Secondly, a rapid (8 min), reliable, and non-destructive method for the quantification of ascorbic acid by 1D 1H-NMR spectroscopy was developed and validated. The LOD and LOQ were 0.05 and 0.15 mg/mL, respectively. These two approaches could be combined to better characterize ingredients derived from acerola and incorporated into food supplements.

The present study was carried out to investigate the nutritional composition and to assess the bioactivity of six underutilized fruits collected from three provinces of Sri Lanka. The selected fruit species were Màdan (Syzygium cumini), Maha Karamba (Carissa carandas), Himbutu (Salacia chinensis), Ugurassa (Flacourtia indica), Barbados cherry (Malpighia emarginata), and Ceylon gooseberry (Dovyalis hebecarpa). The proximate composition, total dietary fiber content, mineral content, total phenolic content, and vanillin contents were determined using standard methods. The antioxidant activity of methanolic extracts of fruits was assessed using FRAP and DPPH assays. Uguressa extract exhibited the highest dietary fiber content (12.25 ± 0.29 of fresh fruit weight) while the lowest was observed in Barbados cherry (6.01 ± 1.10 g/100 g). The total phenolic content (TPC) of fruits ranged from 6.8 ± 0.4 to 10.3 ± 0.3 milligram gallic acid equivalents/g fruit. Barbados cherry showed the highest antioxidant activity (AOA) as measured by FRAP (0.022 ± 0.003 mM Fe 2+/g fruit) and the highest vanillin content (2.4 mg/kg). The highest potassium (434.60 ± 0.36 mg/kg), phosphorous (16.69 ± 0.46), and calcium contents (23.43 ± 0.45) were observed in Uguressa. Màdan had the highest content of magnesium (13.25 ± 0.38 mg/kg), sodium (5.28 ± 0.30), iron (0.65 ± 0.12 mg/kg), and aluminum (1.15 ± 0.16 mg/kg). The highest manganese content (0.98 ± 0.18 mg/kg) was observed in Himbutu while the highest copper content was found in Uguressa (0.11 ± 0.04 mg/kg) and Maha Karamba (0.11 ± 0.03 mg/kg). The study reveals that six underutilized fruits tested possess high nutritional value and are rich in antioxidant activity. Full article
