Seed for Food The seeds of grain-producing plants are more difficult to harvest than nuts or fruits as food. It has been unclear when early humans began to rely extensively on grains, but Mercader (p. 1680) has discovered films of starch residues on stone tools at a cave site in Mozambique dating to about 100,000 years ago. The residues are consistent with starch grains from wild sorghum and indicate that early humans relied on cereals much earlier than previously thought. The Mozambican… 
The first Australian plant foods at Madjedbebe, 65,000–53,000 years ago
It is demonstrated that Australia’s earliest known human population exploited a range of plant foods, including those requiring processing, as well as a broad diet of plants, which suggest that dietary breadth underpinned the success of early modern human populations in this region.
Developing a Reference Collection for Starch Grain Analysis in Early Neolithic Western Temperate Europe
Abstract While we know that cereals played an important role in the diet of Linearbandkeramik (LBK) and Blicquy/Villeneuve-Saint-Germain (BVSG) populations in the Paris Basin, many questions remain
Taking Stock of Foodplants Growing in the Cradle of Humankind Fossil Hominin Site, South Africa
Despite a century’s work in the UNESCO Cradle of Humankind World Heritage Site in South Africa, there has been no systematic consideration of the area’s full foodplant regime when palaeo-scientists
Starch Biosynthesis in the Developing Endosperms of Grasses and Cereals
This review outlines the critical stages of growth and development of the endosperm tissue in the Poaceae, including discussion of carbon provision to the growing sink tissue.
Millet microremains—an alternative approach to understand cultivation and use of critical crops in Prehistory
The preliminary results of this study on phytolith morphology, both at single and joined (silica skeletons) morphotypes, and starch grains show great potentials for the identification of different genus or species on the basis of microremains.
Nuts for dinner? Cladium mariscus in the Middle Stone Age at Sibudu, South Africa
The sedge, Cladium mariscus, has been identified in Middle Stone Age deposits at the shelter Sibudu, South Africa, where the leaves were used as “bedding” – an informal floor covering for various


Systematics and Evolution of Sorghum Sect. Sorghum (Gramineae)
The numerous, usually recognized grain sorghums are divided among five basic races, bicolor, caudatum, durra, guinea and kafir, and ten hybrid races that each combine characteristics of at least two of these basic races.
Effect of Grain Structure and Cooking on Sorghum and Maize in vitro Protein Digestibility
Abstract Uncooked and cooked sorghum showed improvement in in vitro protein digestibility as the structural complexity of the sample reduced from whole grain flour through endosperm flour to protein
Properties of Starches Isolated from Sorghum Floury and Corneous Endosperm
Decorticated grains of three sorghum cultivars of intermediate grain hardness were individually dissected to separate the floury and the corneous endosperm fractions. The starch and polymeric
Starch Granule Structural Changes and Amylolytic Patterns in Processed Sorghum Grain
Starch granule structural changes in steam flaked, micronized and popped sorghum grain and amylolysis of that starch by purified porcine pancreatic amylase and rumen microflora were studied by
Starch granule porosity and its changes by means of amylolysis
Thepresent work is a review on hydrolysis of native starch using a- and glucoamylases and its influence on starch granules porosity. Changes of specific surface area of starch granules were
