“…The Fe contents may have a high variation between genotypes and observation time (3 MAP and 5 MAP). Alamu et al (2022) reported research on 400 genotypes of cassava in Nigeria and found the iron in cassava leaves was in the range of 43-660 mg kg-1, zinc from 16 to 440 mg kg-1, and magnesium 1760-6500 mg kg-1, confirming that genetic factor influenced the mineral content of cassava leaves. --------------ppm -------------- Various factors, including light intensity, can influence mineral contents, where the higher the light intensity, the higher the photosynthesis process and iron accumulation in leaf tissue (Hamzah and Yusuf, 2019).…”

Cassava leaves’ consumption as vegetables are common in several Asian countries. They contain various nutrients, such as, anthocyanins, carotene, minerals, and vitamins. New varieties with high mineral contents in leaves need development to increase the leaves’ quality as vegetables. This study aimed to identify and characterize cassava genotypes of the MV10 generation resulting from gammaray- induced mutations based on the leaves' morphology, growth characteristics, and mineral contents, using two cultivars and 10 cassava genotypes. All genotypes planted in a randomized complete block design had three replications. The leaf's morphology and mineral contents underwent scrutiny on the third to fifth leaf below the apical shoot. The mineral content analysis used the Atomic Absorption Spectrophotometry method. Data analysis comprised the ANOVA test and descriptive analysis. This study revealed petiole length, leaf lobe length, and leaf lobe width were significantly different between genotypes at four months after planting (MAP). However, no meaningful difference showed for the plant height, stem diameter, and number of leaves among genotypes. In general, the leaf morphology consisted of purplish green apical leaves with present pubescence; the shape of the central leaflet is lanceolate; the petiole color is reddish to greenish; leaves are dark green with five to seven leaf lobes; leaf veins are reddish-green; smooth lobe margins; and horizontal petiole orientation. The genotypes affect mineral contents, as the genotype with the highest Mg contents was G6-2-15-5-3, and the one with the highest Zn contents was G2D1-422. Fe contents showed more variations between genotypes, and no genotype showed consistently high Fe contents. This research produced promising genotypes for Mg or Zn contents in leaves for future cassava varieties for vegetable production.

“…Cassava is planted for its edible tubers that have a high carbohydrate content [5]. Cassava leaves are a source of protein, vitamins, and minerals [6]. In the MRB, cassava is predominantly produced by small-holder family farmers, with some external inputs and little knowledge of organic cassava cultivation practices.…”

Organic cassava flour and products are in high demand. However, the expansion of organic cassava (OCS) production is rather slow. To increase OCS production, extension workers, cassava flour mills, farmers, and researchers have been collaborating to support the farmers, but the planted areas have remained limited. This research aimed at understanding the current issues in scaling up the organic cassava production. The findings were subsequently used to formulate scenarios and recommendations for the collaborative scale-up of organic cassava production in the Mekong River Basin (MRB). We carried out a six-step foresight process with leaders of organic cassava farmers, the staff of organic cassava flour mills and factories, extension workers, the staff of research agencies, and local policy makers in Thailand. The results revealed two key factors or drivers of changes, namely, the degree of collaboration among stakeholders using multiple-view scenarios or a single-view situation and the degree of learning and communication about OCS that future stakeholders are likely to experience. Four possible scenarios for a scaling-up system of OCS production in the MRB were developed. The foresight process allowed for recognizing multiple views and opinions about the OCS production scaling-up process, considered as a whole system. The system was found to consist of various interdependent components. The process highlighted the need to increase the capacity and opportunities for productive collaboration in research and development. We concluded that the MRB members should issue a policy formulating a joint task force to coordinate the existing institutions’ plans and resources towards an actionable OCS production scaling-up system for the MRB in 2030.

“…However, its by-products such as leaves and tuber peel are usually disposed of as waste, which ultimately pollutes the environment. To date, several studies have been conducted to determine the nutritional composition and potential benefits of cassava leaves [2][3][4][5][6] and peel [7][8][9][10][11][12][13]. In most of these studies, it has been well documented that cassava leaves are a rich source of protein and other valuable nutrients such as vitamins, minerals, and antioxidants [1,14].…”

Valorization of Cassava By-Products: Cyanide Content and Quality Characteristics of Leaves and Peel

et al. 2023

Cassava production generates significant amounts of by-products such as leaves and tuber peel. Instead of considering them as waste, valorization aims to find sustainable ways to utilize them. However, the presence of cyanide and insoluble fibers poses a major obstacle to their conversion into valuable products. Therefore, the objective of this study is to investigate the changes in cyanide concentration and quality of cassava leaves after mechanical pressing and in tuber peel after treatment with an enzyme solution. Frozen leaves were screw-pressed into their fractions: juice, and press cake. The results show that the cyanide level in the press cake was reduced to 73.56% and was concentrated by 97.48% in the juice compared to the frozen leaves. However, the crude protein values of the frozen leaves, juice, and press cake did not differ significantly (p > 0.05), and were 27.09%, 25.47%, and 23.82%, respectively. In addition, the results for the peel revealed that pretreatment with Viscozyme® L, which assists in the mechanical peeling of cassava tubers, also contributed to a reduction in cyanide and insoluble fiber in the peel. Cyanide content was lowered by 53.89–58.94% in enzyme-treated peel from all three runs (ETP1-3) when compared to fresh peel (FP), while the reduction was only 8.63% in the control peel (CP) treated with hot water without enzyme solution. The insoluble fibers in cassava peel, such as neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), and crude fiber (CF), were also degraded more effectively after treatment with an enzyme solution than with hot water.
