Ítem Microencapsulation of Propolis and Honey Using Mixtures of Maltodextrin/Tara Gum and Modified Native Potato Starch/Tara Gum(Multidisciplinary Digital Publishing Institute. Food, 2023) Gutiérrez Gómez, Edgar; Ligarda Samanez, Carlos A.; Choque Quispe, David; Moscoso Moscoso, Elibet; Huamán Carrión, Mary L.; Ramos Pacheco, Betsy S.; Germán De la Cruz; Arévalo Quijano, José C.; Muñoz Saenz, Jenny C.; Muñoz Melgarejo, Mauricio; Quispe Quezada, Uriel Rigoberto; Luciano Alipio, Rober; Zamalloa Puma, Miluska M.; Álvarez López, Genaro Julio; Sucari León, ReynaldoEthanolic extracts of propolis and bee honey contain substances beneficial to human health. Mixtures of wall materials were compared in spray-drying microencapsulation of ethanolic extracts of propolis and bee honey rich in bioactive compounds. Maltodextrin and tara gum were used to obtain microencapsulates A, and modified native potato starch and tara gum were used for microencapsulates B. High values of phenolic compounds, flavonoids, and antioxidant capacity were obtained in microcapsules A and B, and the results obtained in terms of encapsulation efficiency, yield, hygroscopicity, solubility, moisture, Aw, bulk density, and color were typical of the spray-drying process. On the other hand, spherical and elliptical microparticles of sizes between 7.83 and 53.7 µm with light and medium stability were observed. Thermogravimetric properties were similar in both microencapsulates; total organic carbon, SEM-EDS, and FTIR analyses corroborated the encapsulation. X-ray diffractogram exhibited amorphous structures, and the release kinetics of phenolic compounds presented high values from 8.13 to 12.58 mg GAE/g between 7 and 13 h. Finally, modified potato starch is a better encapsulant than maltodextrin because it has better core protection and controlled release of the encapsulated bioactive compounds.Ítem Nanoencapsulation of Phenolic Extracts from Native Potato Clones (Solanum tuberosum spp. andigena) by Spray Drying(Multidisciplinary Digital Publishing Institute. Molecules, 2023) Gutiérrez Gómez, Edgar; Ligarda Samanez, Carlos A.; Choque Quispe, David; Moscoso Moscoso, Elibet; Palomino Rincón, Henry; Taipe Pardo, Fredy; Aguirre Landa, John Peter; Arévalo Quijano, José C.; Muñoz Saenz, Jenny C.; Quispe Quezada, Uriel Rigoberto; Huamán Carrión, Mary L.; Sucari León, Reynaldo; Luciano Alipio, Rober; Muñoz Saenz, Judy M.; Guzmán Gutiérrez, Rodrigo J.Native potato clones grown in Peru contain bioactive compounds beneficial to human health. This study aimed to optimize the spray-drying nanoencapsulation of native potato phenolic extracts utilizing a central composite design and response surface methodology, obtaining the optimal treatment to an inlet temperature of 120 °C and an airflow of 141 L/h in the nano spray dryer B-90, which allowed maximizing the yield of encapsulation, antioxidant capacity (DPPH), encapsulation efficiency (EE), total phenolic compounds, and total flavonoids; on the other hand, it allowed minimizing hygroscopicity, water activity (Aw), and moisture. Instrumental characterization of the nanocapsules was also carried out, observing a gain in lightness, reddening of the color, and spherical nanoparticles of heterogeneous size (133.09–165.13 nm) with a negative ζ potential. Thermal, infrared, and morphological analyses confirmed the encapsulation of the core in the wall materials. Furthermore, an in vitro release study of phenolic compounds in an aqueous solution achieved a maximum value of 9.86 mg GAE/g after 12 h. Finally, the obtained nanocapsules could be used in the food and pharmaceutical industry.Ítem Physicochemical and Sensory Evaluation of Gummy Candies Fortified with Microcapsules of Guinea Pig (Cavia porcellus) Blood Erythrocytes and Tumbo (Passiflora tarminiana) Juice(Multidisciplinary Digital Publishing Institute. Applied sciences, 2025) Sucari León, Reynaldo; Ligarda Samanez, Carlos A.; Villano Limache, Eliana; Pichihua Oscco, Williams; Choque Quispe, David; Calderón Huamaní, Dante Fermín; De la Cruz, Germán; Luciano Alipio, Rober; Calsina Ponce, Wilber Cesar; Aroquipa Durán, Yolanda; Campos Huamaní, María José VictoriaRecently, interest in developing functional foods that promote health has grown significantly. This study aimed to evaluate the feasibility of microencapsulating guinea pig blood erythrocytes by vacuum drying and incorporating them into gummies fortified with tumbo juice. Physicochemical analysis (proximate analysis, iron content, color, pH, soluble solids, and particle size) and functional group analysis by Fourier transform infrared spectrophotometry were performed on three formulations of gummy candy with added encapsulated erythrocytes from guinea pig blood (EEGPB): F1 (4% EEGPB), F2 (5% EEGPB), and F3 (6% EEGPB). The results showed a significant decrease in the moisture content (52.02% in F1 to 43.27% in F3) and increases in protein (11.44% in F3) and iron (2.63 mg Fe/g in F3) contents when higher EEGPB levels were used. Sensory evaluation revealed that F3 was the most acceptable formulation in terms of taste, aroma, and texture, with no significant differences in color. FTIR analysis confirmed physical incorporation with no chemical interactions between ingredients. These results demonstrate that the encapsulation of erythrocytes by vacuum drying not only preserves the bioactive compounds but also improves the organoleptic properties of the gummies, making them an attractive product for consumers. In conclusion, this technique is effective for fortifying functional foods and has potential application in other food products. This approach represents a significant advance in the development of innovative functional foods.Ítem Preliminary Assessment of Tara Gum as a Wall Material: Physicochemical, Structural, Thermal, and Rheological Analyses of Different Drying Methods(Multidisciplinary Digital Publishing Institute. Polymers, 2024) Sucari León, Reynaldo; Moscoso Moscoso, Elibet; Ligarda Samanez, Carlos A.; Choque Quispe, David; Huamán Carrión, Mary L.; Arévalo Quijano, José C.; De la Cruz, Germán; Luciano Alipio, Rober; Calsina Ponce, Wilber Cesar; Quispe Quezada, Uriel Rigoberto; Calderón Huamaní, Dante FerminTara gum, a natural biopolymer extracted from Caesalpinia spinosa seeds, was investigated in this study. Wall materials were produced using spray drying, forced convection, and vacuum oven drying. In addition, a commercial sample obtained through mechanical methods and direct milling was used as a reference. The gums exhibited low moisture content (8.63% to 12.55%), water activity (0.37 to 0.41), bulk density (0.43 to 0.76 g/mL), and hygroscopicity (10.51% to 11.42%). This allows adequate physical and microbiological stability during storage. Polydisperse particles were obtained, ranging in size from 3.46 µm to 139.60 µm. Fourier transform infrared spectroscopy characterisation confirmed the polysaccharide nature of tara gum, primarily composed of galactomannans. Among the drying methods, spray drying produced the gum with the best physicochemical characteristics, including higher lightness, moderate stability, smaller particle size, and high glass transition temperature (141.69 °C). Regarding rheological properties, it demonstrated a non-Newtonian pseudoplastic behaviour that the power law could accurately describe. The apparent viscosity of the aqueous dispersions of the gum decreased with increasing temperature. In summary, the results establish the potential of tara gum as a wall material applicable in the food and pharmaceutical industries.
