“…Despite the observation by Johns and Brewster (1916) that kafirin solutions gelled readily on cooling even at low concentration, there have been no systematic studies of this phenomenon in comparison to zein. However, it is well-known that zein gelation occurs readily at high concentration (20%-40%), normally within a day (Shukla & Cheryan, 2001).…”

“…According to Osborne (1909), the first mention that sorghum grain contained a considerable quantity of an alcohol‐soluble protein was by Kreusler, sometime after 1869. However, the first detailed study of kafirin was by Johns and Brewster (1916). These authors coined the name kafirin from “kafir corn,” the then common English name for sorghum.…”

Do kafirin bioplastic materials have unique functional characteristics?

Background and Objectives: There is considerable interest in kafirin, sorghum prolamin, as a bioplastic material because it apparently produces bioplastics with superior functional properties. This review evaluates the evidence, focussing on research directly comparing the properties of kafirin bioplastics (films and elastomers) with those from zein and gluten.Findings: Kafirin and zein are more hydrophobic than gluten but there is little difference in hydrophobicity between them. Kafirin and zein films have better moisture barrier properties than gluten films. Films made from total kafirin (α-, β-, and γ-kafirins) are stronger and take up less moisture than films from commercial zein (essentially α-zein). However, total kafirin-and total zein films have similar moisture uptake. Also, there is little difference in oxygen barrier properties between total kafirin-and commercial zein films. Total kafirin elastomers have better elastic recovery than commercial-and total zein elastomers and similar elastic recovery to gluten. Conclusions:The better functional properties of kafirin bioplastics compared to commercial zein bioplastics seems to be largely due to the greater disulfide bonded polymerization of kafirin polypeptides, involving the cysteine-rich βand γ-kafirin classes. Significance and Novelty: This work should stimulate research into disulfidebonded polymerization of prolamins to improve their bioplastic functionality.

“…Publications that pertain to especially food resources such as the cereal grain Sorghum (Sorghum bicolor) have continued to use Kaffir or Kafir corn. Some of its proteins are thus seemingly derivatively named as Kaffirins or Kafirins (Johns & Brewster, 1916). Thai lime (Citrus hystrix) is also prevalently called Kaffir lime in literature.…”

It is trite that most Indigenous food resources in former politically colonised nations have been given English or some other Western common or trivial names. The oppressed people especially in southern Africa were not spared from derogatory and/or racist names such as Kaffir or Kafir, a derogatory reference name equivalent to Nigga or Negro that was used in America. Over time and as political freedom and independence were gained through liberation struggles between the colonisers and the colonised, the use of derogatory and/or racist names against the formerly oppressed people became legally actionable. It is almost forgotten that the offensive, derogatory and/or racist names were not limited to the oppressed people. The natural environments, land and other resources such as Indigenous plants, fruits, rivers, serene spaces and animals were also apparently named by the colonisers and Western botanists or those who allegedly discovered these resources, even though the Indigenous names for such resources existed before the arrival of different agents of colonialisation.Although, human society in general has learnt to no longer use racist and/or derogatory words such as Negro, Nigga, Kaffir or Kafir as common names or nouns, the scientific community seems to lag behind. Some questions arise such as has the scientific community learnt this lesson? Have scientific communications and their related communication platforms such as editors and publishers learnt this lesson?

“…These storage proteins, called kafirin proteins (Johns and Brewster, 1916), are defined as prolamin proteins. Kafirin proteins make up 60 to 70% of the total protein in sorghum grain and are the main storage protein, much like zein proteins in corn kernels (Duodu et al, 2003).…”

Graduate Student Literature Review: Current perspectives on whole-plant sorghum silage production and utilization by lactating dairy cows

The purpose of this literature review is to evaluate current research into and understanding of whole-plant sorghum silage production and the effect of feeding whole-plant sorghum silage on lactation performance of dairy cows. Sorghum's drought tolerance, water efficiency, and low cost of production make it an intriguing crop in areas where whole-plant corn silage production may be limited. Currently, urban land encroachment and reduced water availability have increased social and economic pressures on farms to improve crop production efficiency. As these challenges become more prevalent, greater reliance on sorghum can be expected because of its ability to produce high dry matter yields while maintaining nutritive value, even under less-than-ideal growing conditions. Moreover, whole-plant sorghum silage provides both physically effective fiber and energy through fiber and grain fractions. Advancements in sorghum genetics and mechanical processing have the potential to alleviate common challenges associated with whole-plant sorghum silage supplementation, such as increased neutral detergent fiber and decreased neutral detergent fiber digestibility, starch concentration, and starch digestibility. These nutritive challenges must be overcome for whole-plant sorghum silage to be a viable alternative to whole-plant corn silage.
