In this phase:<\/p>\n<p class=\"western\">1. they absorb large quantities of water [2]<br \/>\n2. they increase the viscosity of the liquid phase [3]<br \/>\n3. they compete with gluten proteins for hydration [2]<\/p>\n<p class=\"western\"><b>This has two main effects:<\/b><\/p>\n<p class=\"western\">1. temporary reduction of the continuity of the protein network [2]<br \/>\n2. increase in the viscosity of the system [3]<\/p>\n<p class=\"western\" align=\"JUSTIFY\">The observed phenomenon should not necessarily be interpreted as structural damage, but rather as a redistribution of water between proteins and polysaccharides [2].<\/p>\n<p class=\"western\"><b>2.2 Cold maturation: slow hydration of the polysaccharide matrix<\/b><\/p>\n<p class=\"western\">During storage in the refrigerator the following may occur:<\/p>\n<p class=\"western\">1. progressive hydration of insoluble arabinoxylans [2]<br \/>\n2. partial solubilization of some fractions [3]<br \/>\n3. increase in the viscosity of the aqueous phase [3]<\/p>\n<p class=\"western\"><b>This may produce a more continuous but less elastic matrix, in which:<\/b><\/p>\n<p class=\"western\">1. the gluten network appears more relaxed [5]<br \/>\n2. the polysaccharide phase is more hydrated<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Within the framework of the dynamic model, this phase corresponds to a biochemical relaxation of the matrix.<\/p>\n<p class=\"western\"><b>2.3 Post-cold storage critical window<\/b><\/p>\n<p class=\"western\">When the dough returns to a higher temperature, the following occur simultaneously:<\/p>\n<p class=\"western\">1. reactivation of fermentation<br \/>\n2. increase in gas pressure<br \/>\n3. variation in the viscosity of the polysaccharide matrix [3]<\/p>\n<p class=\"western\"><b>In this phase arabinoxylans may:<\/b><\/p>\n<p class=\"western\">1. increase the viscous resistance of the system [3]<br \/>\n2. make the surface more fragile in the case of non-uniform hydration [4]<\/p>\n<p class=\"western\" align=\"JUSTIFY\">This may explain the appearance of temporary surface ruptures. From this perspective, the surface of the dough may behave like a heterogeneous viscoelastic membrane [4].<\/p>\n<p class=\"western\"><b>2.4 Network reorganization<\/b><\/p>\n<p class=\"western\">During warm resting and handling:<\/p>\n<p class=\"western\">1. the protein network may reorganize part of the disulfide bonds [5]<br \/>\n2. arabinoxylans may contribute to forming a continuous viscous matrix [3]<\/p>\n<p class=\"western\">This results in a composite structure composed of:<\/p>\n<p class=\"western\">1. protein network<br \/>\n2. polysaccharide matrix<\/p>\n<p class=\"western\" align=\"JUSTIFY\">This aspect is particularly relevant in cereals with weak gluten, in which dough structure is often hybrid rather than purely gluten-based [6].<\/p>\n<p class=\"western\" align=\"JUSTIFY\">&#8220;It is also plausible that a fraction of gluten proteins is not initially fully integrated into the network due to incomplete hydration or uneven water distribution within the dough matrix. During resting and handling, the progressive redistribution of water and the relaxation of the structure may allow these protein fractions to become progressively incorporated into the gluten network, contributing to the recovery of cohesion observed experimentally.&#8221;system. This mechanism may contribute to the observed recovery of cohesion.\u201d<\/p>\n<p class=\"western\"><b>2.5 Final effect on the crumb<\/b><\/p>\n<p class=\"western\" align=\"JUSTIFY\">When the system is well balanced, the structure that retains gas derives from the interaction between:<\/p>\n<p class=\"western\">1. protein network<br \/>\n2. viscosity of the polysaccharide phase [3]<br \/>\n3. gelatinized starch<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Even in less balanced systems, such as in your Series II, arabinoxylans may contribute to retaining part of the gas, even in the presence of a less organized protein network. This is consistent with the observation of an irregular but stable crumb and of bread that remains functional [3].<\/p>\n<p class=\"western\"><span style=\"font-size: large;\"><b>In summary<\/b><\/span><\/p>\n<p class=\"western\">In einkorn, dough structure can be interpreted as the result of the interaction between:<\/p>\n<p class=\"western\">1. protein network<br \/>\n2. cell-wall polysaccharide matrix<\/p>\n<p class=\"western\">In this system arabinoxylans contribute to:<\/p>\n<p class=\"western\">1. regulation of the viscosity of the aqueous phase [3]<br \/>\n2. distribution of water in the dough [2]<br \/>\n3. stabilization of the structure [3]<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In cereals with limited gluten development capacity, these polysaccharides play a complementary role in the retention of fermentation gases [3][6].<\/p>\n<ol start=\"3\">\n<li>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Role of the polysaccharide matrix in ancient wheats<\/b><\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"western\" align=\"JUSTIFY\">Some studies indicate that in ancient wheats such as einkorn, emmer, and spelt, dough structure does not depend exclusively on the gluten network but is also influenced to a greater extent by the non-starch matrix of the cell wall [6][7].<\/p>\n<p class=\"western\">Compared with modern wheats, these cereals show:<\/p>\n<p class=\"western\">1. a gluten network that is generally weaker and less continuous [6]<br \/>\n2. a greater relative influence of non-protein components, including arabinoxylans and other fibers [2][3]<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In this context, the dough may be interpreted as less gluten-dominant and more matrix-dominant, that is, more dependent on the polysaccharide matrix and its interactions with water and proteins [3][6].<\/p>\n<p class=\"western\">This theoretical framework is consistent with what was observed in the present study:<\/p>\n<p class=\"western\">1. the protein network shows a temporary loss of continuity<br \/>\n2. the overall structure of the dough remains functional<br \/>\n3. a recovery of cohesion is observed after a phase of instability<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Consequently, in einkorn the stability of the dough may depend not only on the initial integrity of the gluten network but also on the ability of the overall matrix to reorganize and redistribute internal stresses.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">It should be specified, however, that in the present study the components of the non-starch matrix were not measured directly. Their role should therefore be considered as an interpretative hypothesis consistent with the literature, not as direct experimental evidence [2][3][6].<\/p>\n<ol start=\"4\">\n<li>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Interpretation of the experimental results<\/b><\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"western\">The experimental documentation clearly highlights several points:<\/p>\n<p class=\"western\">1. the dough network loses continuity after removal from the cold chamber<br \/>\n2. surface ruptures and temporary fragility appear<br \/>\n3. after resting and handling the mass recovers cohesion and continuity<br \/>\n4. the final bread shows a functional structure and effective gas retention<\/p>\n<p class=\"western\">The observed sequence:<\/p>\n<p class=\"western\">relaxed network \u2192 surface instability \u2192 reorganization \u2192 functional structure<\/p>\n<p class=\"western\">is compatible with complex viscoelastic models described in the literature [4].<\/p>\n<p class=\"western\" align=\"JUSTIFY\">From a scientific perspective, this means that einkorn dough does not behave in a linearly degradative way.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">The observed rupture is not necessarily an irreversible structural failure but may be part of a transient phase of matrix reorganization.<\/p>\n<p class=\"western\">This is consistent with:<\/p>\n<p class=\"western\">1. models of viscoelastic materials [4]<br \/>\n2. dynamics of gluten proteins [5]<\/p>\n<p class=\"western\">This is one of the most interesting results of your work.<\/p>\n<ol start=\"5\">\n<li>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Post-cold storage reorganization dynamics: original contribution of the work<\/b><\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"western\" align=\"JUSTIFY\">The literature on ancient wheats mainly focuses on aspects such as protein composition, gluten quality, rheological parameters (alveography and farinography), and final bread volume. In this framework, einkorn is generally described as having weaker gluten, greater extensibility, and lower structural stability [6][7].<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Studies that explicitly analyze the temporal dynamics of the dough network during the process, particularly in the stages following cold maturation, are relatively rare. In particular, the following aspects remain poorly documented:<\/p>\n<p class=\"western\">1. phenomena occurring after thermal reactivation of the dough<br \/>\n2. evolution of the structure during resting at room temperature<br \/>\n3. the possibility of network reorganization following an apparent loss of continuity<\/p>\n<p class=\"western\" align=\"JUSTIFY\">To date, explicit descriptions of this sequence in einkorn appear limited; however, the observed behavior is consistent with general models of viscoelastic systems and with the known properties of the gluten network and the polysaccharide matrix.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">The present study directly addresses this aspect by experimentally documenting the evolutionary sequence of the dough in the post-cold storage phase.<\/p>\n<p class=\"western\">The photographic documentation and experimental protocol coherently highlight the following succession of states:<\/p>\n<ol>\n<li>\n<p class=\"western\">apparently stable network at the end of cold maturation<\/p>\n<\/li>\n<li>\n<p class=\"western\">appearance of surface discontinuities during thermal reactivation<\/p>\n<\/li>\n<li>\n<p class=\"western\">progressive recovery of cohesion following resting and handling<\/p>\n<\/li>\n<li>\n<p class=\"western\">formation of a final functional structure capable of retaining fermentation gases<\/p>\n<\/li>\n<\/ol>\n<p class=\"western\" align=\"JUSTIFY\">This sequence indicates that einkorn dough may pass through a phase of structural instability after cold storage that does not correspond to an irreversible collapse of the network but rather to a transient phase of matrix reorganization.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">This result contrasts with the widespread operational interpretation according to which loss of surface continuity should be considered indicative of irreversible dough damage. On the contrary, the data suggest that this phase may represent a physiological transition of the system.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">From the perspective of soft-matter physics, the observed behavior is compatible with that of complex viscoelastic systems, in which transitions may occur between states characterized by apparent rupture, relaxation, and subsequent structural reorganization, as described for doughs and other structured food systems [4][5].<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In the case of einkorn, this phenomenon may be particularly evident for two main reasons:<\/p>\n<p class=\"western\" align=\"JUSTIFY\">the lower dominance of the gluten network compared with modern wheats [6]<br \/>\nthe greater relative influence of the non-protein matrix, including polysaccharides such as arabinoxylans, on the viscosity and structure of the system [2][3]<\/p>\n<p class=\"western\" align=\"JUSTIFY\">These conditions make structural transitions less masked and therefore more observable at the macroscopic level.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">In light of these observations, the present work suggests that in einkorn the final quality of the dough does not depend exclusively on the initial strength of the protein network but on the synchronization between matrix reorganization and fermentative development.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Within this framework, the post-cold storage phase emerges as a critical window of the process, in which phenomena of apparent instability may actively contribute to the construction of the final dough structure.<\/p>\n<ol start=\"6\">\n<li>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Scientifically correct formulation<\/b><\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"western\">A rigorous formulation could be the following:<\/p>\n<p class=\"western\" align=\"JUSTIFY\">Experimental observations show that einkorn dough undergoes a phase of surface instability after thermal reactivation, followed by recovery of structural cohesion during resting and handling. This behavior suggests a non-linear dynamics of the dough matrix. Although in the present study the non-starch components of the cell wall were not measured directly, the observed phenomenon is consistent with models described in the literature in which matrix polysaccharides, particularly arabinoxylans, contribute to system viscosity and gas retention in cereals with limited gluten development capacity [2][3][6].<\/p>\n<ol start=\"7\">\n<li>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Conclusions<\/b><\/span><\/p>\n<\/li>\n<\/ol>\n<p class=\"western\" align=\"JUSTIFY\">The main conclusion of the work is that, in einkorn, temporary surface rupture does not necessarily imply failure of the network.<\/p>\n<p class=\"western\">The network may:<\/p>\n<p class=\"western\"><span style=\"color: #800000;\"><b>break \u2192 reorganize \u2192 stabilize<\/b><\/span><\/p>\n<p class=\"western\">if thermal and temporal conditions are appropriate [4][5].<\/p>\n<p class=\"western\" align=\"JUSTIFY\">This result is relevant because it contrasts with the widespread idea that einkorn simply collapses once network continuity is lost.<\/p>\n<p class=\"western\" align=\"JUSTIFY\">More generally, your work suggests that einkorn dough should be interpreted as a dynamic system, in which final functionality depends on the interaction between:<\/p>\n<p class=\"western\">1. protein network<br \/>\n2. polysaccharide matrix<br \/>\n3. fermentative development<br \/>\n4. timing and thermal conditions of the process<\/p>\n<p class=\"western\"><span style=\"font-size: large;\"><b>Reference bibliography<\/b><\/span><\/p>\n<p class=\"western\">[1] Izydorczyk, M.
