The valorization of wood derived from thinning operations in tropical plantations represents an alternative to enhance the sustainability and profitability of forest production systems. This study evaluated the hygroscopic, physical, and machining properties of 13-year-old Simarouba amara Aubl. thinning wood obtained from a plantation established in the Peruvian Amazon. Two planting spacings (2 × 2 m and 3 × 3 m) and three longitudinal stem positions (base, middle, and apex) were analyzed using a factorial design and generalized linear mixed models. Planting density and longitudinal position significantly influenced (p < 0.05) most of the evaluated properties. The saturated moisture content increased from 96.17% at the base to 135.42% at the apex, whereas basic density decreased from 0.45 to 0.30 g cm−3. Volumetric shrinkage ranged from 10.19% to 14.81%, and the dimensional stability index varied between 1.66 and 1.91. The first principal component (PC1) explained 98.4% of the total variance and clearly differentiated the treatments. The wood exhibited excellent performance in planing and molding, good performance in drilling, and fair performance in turning, indicating strong potential for the manufacture of higher value-added products and for sustainable utilization in tropical plantation forests.
Secado por Atomización: Tecnología de transformación y conservación en la industria alimentaria
(ITP red CITE, 2026-08) ITP red CITE
Este boletín analiza el secado por atomización (spray drying) y la microencapsulación como estrategias tecnológicas clave para la industria agroalimentaria; destacando cómo estas soluciones permiten transformar materias primas líquidas, altamente perecibles y subproductos locales en ingredientes funcionales en polvo estables, con mayor vida útil y menor costo logístico. Asimismo, resalta su aplicación en la protección de compuestos bioactivos, como antioxidantes, proteínas y probióticos, facilitando su integración en matrices como bebidas instantáneas, nutracéuticos y lácteos. Finalmente, el boletín orienta a las Mipymes peruanas a validar estas innovaciones mediante servicios de pilotaje del CITE, permitiéndoles reducir las pérdidas poscosecha, fomentar la economía circular y acceder de manera competitiva a mercados B2B premium y de exportación.
The importance of taxonomic classification of ‘Pashaco’ and ‘Huayruro’ in the Fabaceae family for timber production in Loreto, Peru
(Universidade Federal do Paraná, 2024-08-27) Villacorta-Gonzáles, Carlos; Del-Aguila-Mendoza, Lizbeth Carolina; Rios-Paredes, Marcos Antonio; Bartolo-Cuba, John Albert; Silva-Moreno, Henri Frank; Welling, Johannes
In Peru, forest inventories traditionally group different timber species under the same commercial name. The names "pashaco" and "huayruro" in the Amazon exemplify this practice, representing the grouping and commercialization of various Fabaceae species, a family of significant forest and commercial importance in Loreto. This study aimed to taxonomically identify the "pashaco" and "huayruro" individuals a timber company recorded in its forest census and to differentiate each group's species through dendrological characterization. The company's census identified 429 "pashaco" individuals as Albizia niopioides and 150 "huayruro" individuals as Ormosia amazonica. Botanical identification of samples from 80 individuals in each group revealed that the individuals classified as A. niopioides comprised nine species: Schizolobium parahyba var. amazonicum, Dimorphandra cuprea, Pseudopiptadenia suaveolens, Hydrochorea pedicellaris, Enterolobium schomburgkii, Parkia nitida, Parkia igneiflora, Parkia decussata, and Parkia multijuga, with the last being the most common. Similarly, the "huayruro" or Ormosia amazonica classification included Andira macrothyrsa, Batesia floribunda, Ormosia coccinea, Ormosia amazonica, Vataireopsis surinamensis, Vatairea erythrocarpa, Hymenolobium excelsum, Hymenolobium nitidum, and Hymenolobium velutinum, with the latter being the most abundant. This study underscores the need for improved species identification in forest inventories. Dendrological characteristics of stems and leaves can aid in differentiating and identifying these species in forest censuses, fostering sustainable management practices by reducing species grouping and minimizing economic impacts in the timber forest production chain.

Fermentation Arrest Density Modulates Congener Composition and Sensory Profile in Aromatic Grape Distillates
(MDPI AG, 2026-08-12) Gavilan-Figari, Isabel Milagros; García-Hernandez, Karla Patricia; Neyra-Lazaro, Enzo Anthony; Effio-Espinoza, Sebastian Antonio; Bollet, Herman
Stopping fermentation is a critical, yet insufficiently standardised, step in the production of aromatic grape distillates, as it influences residual sugar, yeast metabolism and the availability of volatile precursors. This study evaluated the must density at the time of fermentation arrest as a process control parameter for Torontel grape distillates. Five treatments were established by halting fermentation at densities ranging from 1.050 to 1.010 g/mL, followed by batch distillation. The distillates were evaluated using physicochemical analyses, including alcohol strength and the concentration of key volatile congeners such as methanol, acetaldehyde and higher alcohols. Furthermore, these analyses were complemented by gas chromatography with flame ionisation detection (GC-FID) and sensory evaluation by experts. Increased must density was associated with higher concentrations of methanol, acetaldehyde and higher alcohols, whereas ethanol content decreased. Although clear differences in chemical composition were observed among the evaluated process conditions, overall sensory acceptability exhibited only limited variation across the fermentation arrest densities. However, distillates obtained from intermediate density levels showed better aromatic balance and sensory harmony. Multivariate analysis suggested that fermentation arrest density was associated with the main patterns of chemical variability observed among the evaluated distillates, whereas its association with overall sensory perception appeared to be more limited. These findings provide a useful framework for optimising fermentation arrest strategies in the production of aromatic partially fermented grape distillates.
