“…Based on these findings, it was evident that the planting distances of hot pepper plants were highly related to the quantity of the pepper obtained at harvest and affected mechanical harvesting efficiency. However, planting distance was used at a variety of levels: 35 cm in Canada [27], 38-45 cm in the United Kingdom [28], 30-45 cm in America [29,30], 30 cm in Brazil [31], and 30-40 cm in the Republic of Korea [32]. Based on the total yield of hot peppers per plant and marketable fruit yield per plant, a previous study indicated that a low planting density resulted in a high total yield of hot pepper [33][34][35].…”

Effect of Planting Distance on the Mechanical Harvesting of Hot Pepper

Hot peppers are well known for being spicy and also have a high nutrient content. Human resources have formerly been used to harvest hot peppers; however, a high level of musculoskeletal risk to the human workforce has been reported. Therefore, to reduce the risk to farmers and replace the human workforce, the mechanical harvesting of hot pepper and steps to improve the harvesting efficiency of farmers were conducted. To achieve this, the effect of planting distance on the mechanical harvesting of hot peppers was analyzed at three planting distances (30, 40, and 50 cm) with several cultivars. Subsequently, machine-harvested hot peppers were classified into five groups (marketable, damaged, lost, unharvested, and twigged hot pepper), depending on their postharvest status. The average weight ratio of each group was then calculated, after which statistical analyses were conducted. The effect of planting distance on mechanical harvesting was then analyzed by comparing the differences between each group’s average weight ratio and the total weight of hot pepper, which was simultaneously harvested mechanically at each planting distance. Results showed that the average weight ratio of marketable, unharvested, and twigged hot pepper improved as the planting distance increased. However, no effect on the average weight ratio of damaged and lost hot pepper was observed. The highest yield of marketable hot pepper was found at a planting distance of 40 cm, and the average weight ratio to the whole was lower than at 50 cm of planting distance. Thus, the most suitable planting distance for mechanical harvesting was 40 cm.

“…Research on chili pepper varieties for use in mechanical harvesting has been conducted [16]. Recently, to evaluate the suitability for harvest mechanization, previous research was conducted on the nutritional and physiological components of various varieties [17][18][19][20][21] as well as plant spacing, productivity, and quality [22][23][24] according to cultivation methods.…”

Performance Testing and Evaluation of Drum-Type Stem-Separation Device for Pepper Harvester

et al. 2021

The chili pepper harvester has shown potential problems of low pepper stem separation and a high pepper damage rate. The low pepper stem separation has required additional labor, which consists of separating the pepper and stem after pepper harvesting. To improve the stem separation and sorting function of pepper harvesters, three-shaft and four-shaft drum-type stem-separation devices were manufactured, and performance tests were conducted to assess these devices. In an attempt to reduce the damage rate, a brush was used as the teeth in the drum-type stem-separation device. In the factor test, the rotational speeds of shaft 1(A), shaft 2(B), shaft 3(C), and the conveyor for the three-shaft drum were 0.9, 2.7, 1.3, and 0.5 m/s, respectively. The rotational speed of the four-shaft drum was the same as that of the three-shaft drum except for shaft 4(D), and the rotational speed of this additional D was set to 1.3 m/s, which was the same as that of C. In the non-moving status during the non-picking operation of the pepper harvester, the average stem-separation efficiency (SSE) of the four-shaft drum increased by 1.2%, the average pepper with twig rate (PTR) decreased by 5.9%, and the average damage rate (DR) increased by 3.7% compared to the three-shaft drum. In the moving status during the picking operation of the pepper harvester, the SSE of the four-shaft drum increased by 3.6%, the PTR decreased by 9.1%, and the DR increased by 3.8% compared to the three-shaft drum, so an improvement in the pepper stem-separation capacity was observed.

A pimenta Capsicum spp. é uma especiaria utilizada de diversas formas na alimentação, in natura ou industrializada, e em várias culturas gastronômicas. O rico perfil bioativo e de propriedade antioxidante atribuídos as pimentas destaca a espécie Capsicum annuum var. annuum “jalapenho” por apresentar características sensoriais e nutricionais que favorecem seu consumo e processamento industrial. Este trabalho teve como objetivo principal caracterizar a pimenta jalapenho (Capsicum annuum L. var. annuum) em sua composição centesimal, físico-química, de compostos bioativos e capacidade antioxidante. Os resultados demonstraram que o fruto de pimenta jalapenho apresentou valor nutricional semelhante as pimentas de sua espécie e também de outras espécies. As análises físico-química expressam resultados desejáveis para o processamento de produtos derivados da pimenta, com acidez moderada (0,41 ± 0,01 g.100g-1) e tonalidade incidindo entre o laranja e vermelha (hº = 55,17). A atividade antioxidante foi demonstrada através dos métodos de DPPH, FRAP e ABTS para os extratos aquosos do fruto de pimenta jalapenho, com 360,00 ± 5,00 µM ET.g-1, 121,47 ± 2,54 µM ESF.g-1 e 107,40 ± 1,16 µM ET.g-1, respectivamente, obtendo maior atividade pelos métodos FRAP e ABTS. Os compostos bioativos apresentaram teores de 474,64 ± 12,26 mg EAG.100g-1 de compostos fenólicos, 112,88 ± 0,36 mg EQ.100g-1 de flavonoides totais, 3,79 ± 0,26 mg.100g-1 de β-caroteno e 2,72 ± 0,19 mg.100g-1 de licopeno, demonstrando que a pimenta jalapenho é uma fonte expressiva destes compostos bioativos sendo uma matéria-prima de interesse para indústria de alimentos.
