Mapping the variability in physical, cooking, and nutritional properties of Zamnè, a wild food in Burkina Faso

Abstract

Highlights The wild crop Zamnè exhibited characteristics of dry and hard-to-cook legume. The physical, cooking, and nutritional properties of Zamnè showed low variability. It was confirmed that there is a potential mix-up of Zamnè and pseudoZamnès . The traditional cooking of Zamnè evoked over processing defects.

Inventory of human-edible products from native Acacia sensu lato in Africa, America, and Asia: Spotlight on Senegalia seeds, overlooked wild legumes in the arid tropics

“…Accordingly, the non-proteinogenic amino acids reported from Senegalia seeds are discussed in section 5.6. Besides, Guissou et al (2017) have reported a large discrepancy between the sum of 17 proteinogenic amino acids' content (7.8 g/100 g dm) and crude protein content (35-40 g/100 g dm) (Drabo et al, 2020;Hama-Bâ et al, 2017;Msika et al, 2017) from S. macrostachya seeds, suggesting a high content of non-protein nitrogen. The amount of data is very limited and inconsistent, making it difficult to conclude the nutritional property of Senegalia seed proteins.…”

“…Carbohydrates are the principal constituent of Senegalia seeds and evoke high proportions of free sugars (6.8-7.2 g/100 g dm), dietary fibers (16-38 g/100 g dm), and bioactive polysaccharides (Drabo et al, 2020;Mersha et al, 2017;Msika et al, 2017;Yadav & Bharadwaj, 1971;Zongo et al, 2022). Notwithstanding the high dietary fiber contents of Senegalia seeds, their compositions remain poorly investigated.…”

“…Notwithstanding the high dietary fiber contents of Senegalia seeds, their compositions remain poorly investigated. Only one report indicates some soluble fiber contents (3-10 g/ 100 g dm) (Drabo et al, 2020), which are significant in nutritional terms (Englyst et al, 2007). Interestingly, an important fraction of the soluble fibers from S. macrostachya seeds has demonstrated immunomodulatory properties, supporting the health benefits of Senegalia seed carbohydrates (Zongo et al, 2022).…”

“…feathery shoots and seeds, for instance, are mostly reported as edible raw or cooked as famine-emergency foods, traditional foods, delicacies, green vegetables, snacks, and milled as flavoring ingredients or herbal supplements. Yet, S. macrostachya seeds, S. senegal seeds, and S. pennata feathery shoots have been well adopted as traditional foods and delicacies, namely Zamnè (in Burkina Faso), Kumatiya (in Rajasthan, Northern India state), Cha'om (in Southeast Asia), respectively (Drabo et al, 2020;Lomarat et al, 2015;Ram et al, 2014;Savadogo et al, 2011). It is worth highlighting that in addition to their uses as foods, more than 34 products (out of 119) have been reported as herbal supplements for their medicinal applications, supporting the potential of Acacia s.l.…”

Utilization of the basket press method to extract verjuice

“…The true density of the pomace ranged from 1112.10 kg m −3 to 1674.12 kg m −3 . Then pomace porosity was calculated by knowing densities (Drabo et al, 2020; Li et al, 2021). Final pomace porosity was in the range of 12.38% to 23.44%.…”
