“…Composition and concentration of major carotenoids were obtained from HPLC analysis, while total carotenoids were derived from spectrophotometry data of α-carotene in Mas bananas and β-carotene in Raja bananas were 1,556.22 µg/100 g dw and 983.83 µg/100 g dw, respectively. Being the most marketable banana cultivar, Cavendish shows a low amount of β-carotene which corresponds to previous reports suggesting that Cavendish contained 21 to 290 µg/100 g dw of β-carotene [7,24,28].…”

Carotenoid Analysis from Commercial Banana Cultivars (Musa spp.) in Malang, East Java, Indonesia

et al. 2021

Banana, as the world’s most consumed fruit, is a good source of carbohydrate, potassium, fiber, and other essential nutrients such as pro-vitamin A carotenoids. The carotenoid content and composition in bananas commonly sold in fruit shops in Malang have become interesting studies. Five types of banana, i.e. Berlin, Mas, Cavendish, Candi and Raja were characterized using high-performance liquid chromatography and UV-Vis spectrophotometer. The carotenoid concentrations ranged between 347–3,660 µg/100 g dry weight (dw), with the level of vitamin A activity at the range between 6-139 µg RAE/100 g dw. The Mas banana had a higher carotenoid concentration compared to the Berlin, Candi, Raja, and Cavendish varieties.

“…Peak #3 was eluted at min 26.3 having λmax at 451 and 478 nm, thus, identified as β-carotene. Previous studies also reported these compounds as major carotenoids in other banana cultivars in several regions in the world, such as in Australia, Africa, and Asia [10,[24][25][26][27].…”

“…The difference in the composition could mainly be due to the genetic diversity among the Cucurbita species and the environmental conditions under which the pumpkins were grown. The α-carotene, trans-β-carotene, and the total carotenoid content observed in the pumpkin is by far higher than that reported in fruits like banana (Mbabazi et al, 2020). Therefore, considering that trans-β-carotene has 100% pro-vitamin A activity (Carvalho et al, 2014), accessions like Kab5, Kan22, Mit9, Mas16, Mit11 and Fort19 are promising sources of vitamin A. Pro-vitamin A carotenoid availability is of particular importance in developing countries where vitamin A deficiency (VAD) is a significant public health concern.…”

Pumpkin is one of the underutilized fruit-vegetables in Uganda although it is one of the crops believed to have carotenoids with pro-vitamin A activity that are not common to many other crops. While other crops are being bred or fortified to increase their nutritional benefits of β-carotene and other micro nutrients required for healthy growth and care for immunosuppressed people, the value of pumpkins in this regard remains under researched. This study sought to determine the nutritional physico-chemical parameters of selected pumpkin cultivars grown in Uganda. The seeds of 14 cultivars of pumpkin from four agro-ecological zones of Uganda were grown under similar conditions. Their mature pulp was then analyzed for their proximate, mineral and carotenoid composition including glucose, starch, crude fibre, crude fat, ash, crude protein, moisture, iron, zinc, calcium, potassium, lutein, α-carotene, trans-βcarotene, cis-β-carotene, total carotenoid and total pro-vitamin A carotenoid content using standard procedures. The proximate, calcium, potassium and the carotenoid content varied significantly across all the accessions (P˂0.05) while the iron and zinc content did not vary significantly across all the accessions (P˃0.05) respectively. The results from the study show that pumpkin pulp is a good source of dietary fibre, protein, calcium, potassium, iron and carotenoids with pro-vitamin A activity. Therefore, pumpkin can be utilized in the food processing industry as a food supplement and for several other value addition avenues such as wine and flour production.

“…In what ways, then, did the choices made in the lab, which were structured by this array of actants and their relations, imply a choice about who or what would become entangled and disentangled and in what ways? Bananas are of cultural and ritual importance in several African countries, as well as a pivotal source of income and food high in starch and some essential vitamins and minerals (Karamura et al 1999;Mbabazi et al 2020). In choosing bananas as the crop of choice and BXW as the problem to be addressed, the around 100 million people who depend on the cultivation of bananas, most of whom are small-scale farmers residing in East and Central Africa (Karamura, Karamura, and Tinzaara 2012;Tripathi, Mwangi et al 2009;Tripathi, Tripathi et al 2013), initially became entangled.…”

Feminist Crops: A More-than-Human Concept for Advancing Feminist Crop Breeding for Development

Gender matters in agriculture, and crop breeding teams are increasingly being asked to develop plant varieties that respond to the needs and preferences of men and women. Achieving gender-responsive crop breeding requires communication and cooperation across disciplines, not least between crop breeders and gender specialists. The coming together of plant sciences and gender studies necessitates novel ideas, concepts, and approaches that unite nature with culture and the material with the social. However, the development of such approaches is still in its infancy. Empirically grounded in experiences in and observations of social and natural scientists working at the intersection of gender and crop breeding in an African context, this article contributes to filling this gap by proposing the concept of the “feminist crop.” The feminist crop captures the entanglement of crops with women’s embodied practices, knowledges, capabilities, and power, and contributes to an ethico-onto-epistemological and methodological investigation of how intersectional gender identities and relations are embedded in plant–people entanglements. Using examples from banana, yam, and cassava, I explore how the feminist crop can expand the boundaries of how we think about agency, power, and empowerment in agriculture, as well as how plant genome editing grounded in the feminist crop concept may be used as a feminist tool to entangle plants and people in more socially just ways. Ultimately then, the feminist crop contributes to advancing feminist crop breeding.
