“…Drying time of mature pepper berries reported in this study was lower compared to 7 days reported by Roslan and Yudin, (2020). This variation could be caused by differences in weather conditions experienced during drying as sun drying is weather dependent (Shreelavaniya and Kamaraj, 2017). The mean berry moisture content of fresh mature berries (71.61%) reported in this study was consistent with other previous research findings reported moisture content of mature pepper berries to be 65-77% depending on the variety (Azman et al, 2021;Shreelavaniya and Kamaraj, 2017;Paul et al, 2021).…”

Optimal harvest maturity stage determines the on-shelf quality of black pepper (Piper nigrum L.). Small-scale farmers in Morogoro harvest black pepper before reaching full maturity to catch up with high market prices offered early in the season. Unfortunately, traders are complaining on the quality of black pepper from the area. This study evaluated the effect of harvesting stages on post-harvest quality of pepper cultivars grown in the Morogoro district. Pepper cultivars; Babu kati, Babu kubwa, and Ismailia at premature and mature stages were dried on coconut leaves mats to suitable drying stage. Treatments in a 2 x 3 factorial experiment following a complete randomized design (CRD) were replicated thrice. Statistical significance of variables was generated by ANOVA and mean separation by Tukey HSD test at p ≤ 0.05. Results showed a significant (p<0.001) difference between harvest stages and cultivars on berry colour, moisture content, berry firmness, dry recover and weight loss percentage. Pepper berries at pre-mature stage across cultivars had higher (79.11%) initial moisture content than mature berries (71.6%). Mature berries had higher dry recovery percentage (28.84%) than pre mature (15.78%). Mature “Ismailia” berries had the highest firmness (10.5kg/mm2) than premature (5.8 kg/mm2). During sun drying, colour values L*(brightness), and b* (yellowness) decreased significantly while greenness decreased as a* values increased from more negative values to zero in both harvesting stages as pepper berries darkened. Colour changes were sharper on mature than pre-mature harvested pepper corns. These findings will help farmers to make right decision on when to harvest for quality black pepper product. Farmers are recommended to harvest black pepper when mature for better firmness and colour development during drying. Further studies are required to determine the sensory quality and volatile oil contents of the cultivars when harvested premature and mature stages.

Dried red chili variety of Hot Beauty from local Malang city, East Java, Indonesia were determined experimentally at various water contents of 12.009, 13.005, 15.012, 17.248, and 19.003% (wet basis) then monitoring was done based on several physical parameters. The objectives of this research are to determine physical properties of chili such as length, width, thickness, roundness, mean diameter, surface area, bulk density, true density, porosity, coefficient of static friction (towards cardboard surface, metal plate, plywood board, and stainless steel), and compressive force at different moisture content. The results showed that geometrical dimension, roundness, mean diameter, surface area, bulk density, true density, porosity, and coefficient of static friction were linearly increased following the increase of water content. Otherwise, compressive force was decreased following the increase of water contents from 12.009 to 19.003% (wet basis). This can be happened due to high water content causing the increase of internal pressure on cell wall of dry red chili in which this pressure is naturally strengthen the structure of cell wall and make it more rigid.

With the growing concerns over environmental degradation and the increasing demand for sustainable materials, eco-friendly composites have gained considerable attention in recent years. This review paper delves into the promising realm of seed-based fillers, reinforcements and polysaccharidic matrices in the production of biocomposites that are yet focusing on those seeds, which can be considered industrial process waste. Seeds, with their inherent mechanical properties and biodegradability, which are often the waste of production systems, offer a compelling solution to reduce the environmental impact of composite materials. This paper explores the properties of various seeds considered for composite applications and investigates the processing techniques used to incorporate them into composite matrices. Furthermore, it critically analyzes the influence of seed fillers on the mechanical and physical properties of these eco-friendly composites, comparing their performance with traditional counterparts. The environmental benefits, challenges, and limitations associated with seed-based composites from waste seeds are also discussed, as well as their potential applications in diverse industries. Through an assessment of relevant case studies and research findings, this review provides valuable insights into the outlook of seed-based composites as a sustainable alternative in the composite materials landscape, emphasizing their role in promoting a greener and more responsible approach to materials engineering.
