The method is specifically designed for flours characterized by:<br \/>\n1 &#8211; weak gluten,<br \/>\n2 &#8211; high gliadin\/glutenin ratio,<br \/>\n3 &#8211; redominantly viscous-cohesive rheological behavior.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">The presentation of this method derives from one of the tests conducted, selected because it is representative of the full expression of the process.<\/p>\n<p class=\"western\" align=\"JUSTIFY\"><span style=\"font-size: large;\"><b>1 &#8211; Technological context of the approach<\/b><\/span><\/p>\n<p class=\"western\" align=\"JUSTIFY\">Whole flours obtained from stone-milled ancient grains have technological characteristics that differ profoundly from those of modern strong flours commonly used in industrial breadmaking. The \u201cstrength\u201d of a flour, in breadmaking terms, is linked to the ability of the protein fraction to build an elastic, continuous gluten network resistant to the pressure of fermentation gases. Comparative studies on wheat species show that, even in the presence of a high total protein content, ancient species such as einkorn may present a higher gliadin\/glutenin ratio than modern soft wheat. The result is a less elastic and less structurally \u201cload-bearing\u201d network [1] (cf. comparative studies published in the MDPI field).<\/p>\n<p class=\"western\">In practical terms: in other words, a high protein content does not necessarily imply the presence of a functional gluten structure for breadmaking purposes.<\/p>\n<p class=\"western\">The reduced capacity of such flours to develop a continuous and elastic gluten network entails:<br \/>\n1 &#8211; difficulty in retaining the gases produced during fermentation;<br \/>\n2 &#8211; limited tolerance to mechanical processing;<br \/>\n3 &#8211; structural instability of the dough during the proofing stages;<br \/>\n4 &#8211; greater sensitivity to fermentation peaks.<\/p>\n<p class=\"western\">In current practice, these critical issues are often compensated for by:<br \/>\n1 &#8211; blending with high-strength flours;<br \/>\n2 &#8211; use of improver additives;<br \/>\n3 &#8211; use of technological aids.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Such interventions, although effective from a volumetric standpoint, frequently entail a reduction in the nutritional, sensory, and identity-related peculiarities of the original flours, in addition to modifying aspects of digestibility and tolerability.<\/p>\n<p class=\"western\" align=\"JUSTIFY\"><span style=\"font-size: large;\"><b>1.1 The specific case of einkorn<\/b><\/span><\/p>\n<p class=\"western\" align=\"JUSTIFY\">Triticum monococcum is one of the earliest cereals domesticated by humans and is considered one of the oldest wheat species still cultivated. Compared with modern wheats widely used in breadmaking, einkorn has peculiar nutritional and technological characteristics that significantly influence its behavior in doughs.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Several studies have shown that this species often has a relatively high total protein content; however, breadmaking functionality does not depend exclusively on the amount of protein, but rather on the structure and organization of the gluten protein system.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">According to the structural models proposed by Peter R. Shewry and Peter R. Halford (2002) and subsequently further developed by Herbert Wieser (2007), the rheological properties of wheat doughs mainly depend on the interaction between three main protein classes:<br \/>\n1 &#8211; high molecular weight glutenins (HMW-GS);<\/p>\n<p class=\"western\" align=\"JUSTIFY\">2 &#8211; low molecular weight glutenins (LMW-GS);<\/p>\n<p class=\"western\" align=\"JUSTIFY\">3 -gliadins.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In einkorn, the relative distribution of these fractions differs significantly from that of modern soft wheat. In particular, the following have been observed:<\/p>\n<p class=\"western\">1 &#8211; lower formation of high molecular weight protein polymers;<br \/>\n2 &#8211; greater proportion of monomeric proteins;<br \/>\n3 &#8211; limited ability to generate a continuous and structurally stable gluten network.<\/p>\n<p class=\"western\">From a technological standpoint, this generally translates into doughs characterized by:<br \/>\n1 &#8211; lower stability during processing;<br \/>\n2 &#8211; greater extensibility;<br \/>\n3 &#8211; lower ability to retain fermentation gases.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Despite these structural limitations, recent studies have shown that the breadmaking performance of ancient grains can be significantly improved through proper management of the technological process. In particular, techniques based on controlled fermentations, prolonged maturation, and careful management of the thermal conditions of the dough can promote a progressive reorganization of the protein system and improve structural stability during proofing and baking (Luca Cappelli et al., 2019; Gabriele Brandolini and Adriano Hidalgo, 2014).<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In light of these considerations, the present work experimentally analyzes the behavior of the einkorn protein network during a breadmaking process characterized by a prolonged low-temperature maturation phase followed by controlled thermal reactivation of the dough.<\/p>\n<p class=\"western\" align=\"JUSTIFY\"><span style=\"font-size: large;\"><b>2.

perforated bottom,<br \/>\n2 &#8211; walls not completely rigid.<\/p>\n<p class=\"western\"><b>This configuration allows:<\/b><br \/>\n1 &#8211; initial containment of the dough;<br \/>\n2 &#8211; progressive lateral expansion during oven spring;<br \/>\n3 &#8211; transformation of the shape toward a loaf or round loaf.<\/p>\n<p class=\"western\"><b>Structural rationale<\/b><br \/>\nDuring the initial baking stage:<br \/>\n1 &#8211; the increase in temperature causes expansion of trapped gases (air + CO\u2082 + steam);<br \/>\n2 &#8211; the viscosity of the matrix decreases before starch gelatinization;<br \/>\n3 &#8211; the structure is temporarily more deformable.<\/p>\n<p class=\"western\">A partially flexible mold allows the internal thrust to redistribute, avoiding vertical compression and favoring more natural expansion.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">The dough, obviously, can also be placed on a perforated baking tray; in this case it is likely that a more \u201cciabatta-like\u201d shape will be obtained, which may be interesting because it would allow the dough to \u201crise\u201d more freely and form a more airy structure.<\/p>\n<p class=\"western\" align=\"JUSTIFY\"><b>Note:<\/b> Perforated oven trays promote more homogeneous heat transfer and distribution than traditional baking trays<\/p>\n<p class=\"western\"><b>11.3 Mode of heat transfer<\/b><br \/>\nBaking is carried out by placing the container on a rack, not directly on the oven floor.<\/p>\n<p class=\"western\"><b>Difference compared with direct contact<\/b><br \/>\nIn traditional ovens, direct contact with the hot sole:<br \/>\n1 &#8211;

starch gelatinization is not yet complete;<br \/>\n2 &#8211; the structure has not yet reached maximum thermal fixation;<br \/>\n3 &#8211; further residual expansion is still possible.<\/p>\n<p class=\"western\">From a physical standpoint, oven spring is determined by:<br \/>\n1 &#8211;
