Here, we present a simplified system comprising amylose of varying degrees of polymerization in water, with the goal of probing the temperature–concentration phase diagram to determine if a miscibility gap leading to liquid−liquid phase separation might serve as a model for starch granule initiation and, if so, under what conditions.
Findings
A miscibility gap in the cooling-rate-dependent phase behavior is demonstrated for the amylose−water system, with its temperature and concentration depending on the degree of polymerization (DP) of the starch. Liquid–liquid phase separation within this miscibility gap followed by crystallization of the polymer-rich phase produced spherulites. If crystallization preceded liquid–liquid phase separation, a precipitate or gel was formed. The upper critical solution temperature appeared between 60°C and 70°C, and the miscibility gap was observed between 5% and 30%–50% w/w starch, depending on DP for DP ≥ 68. For DP 29, the miscibility gap occurred at concentrations ≥ 20% w/w.
Conclusions
A cooling-rate-dependent miscibility gap in the temperature–concentration phase diagram has been observed in aqueous amylose solutions under reasonable ambient conditions of temperature and starch concentration, allowing phase separation to occur within plastids in vivo.
Significance and Novelty
This work provides a biophysical complement to the biochemistry associated with starch granule initiation.

The objective of this study was to evaluate a series of Rapid Visco Analyzer (RVA) methods for their ability to produce results that were predictive of hand folded Japanese sponge cake (JSC) quality. Two solvents (water and 50% [w/w] aqueous sucrose) and two temperature profiles (Standard 1 [STD 1] and an internal cake temperature profile) were selected to run across a set of flour samples from two crop years. The RVA results were previously analyzed (and published) for their ability to produce results that were predictive of mechanically folded JSC. Due to the continued use of the hand fold method, there was a need to understand how these RVA methods produced results that were predictive of hand folded JSC quality. Hand folded JSC is prepared by manually folding the flour into the egg sugar mixture using a wooden paddle, while the mechanical folding method utilizes a KitchenAid with attached paddle.
Findings
Water, 5% lactic acid, 5% sodium carbonate, and 50% sucrose SRC solvents showed no significant correlations with JSC quality. RVA viscosity results from both profiles using water were generally not significantly correlated with JSC quality while the sucrose solvent batter pasting viscosity (BPV) was significantly correlated. RVA BPV run with the internal cake temperature profile using the sucrose solvent showed significant correlations with hand folded JSC volume (r = 0.76, p ≤ 0.05), firmness (r = −0.89, p ≤ 0.01), and overall score (r = 0.79, p ≤ 0.01).
Conclusions
The RVA BPV results showed that a 50% (w/w) sucrose solvent, when compared to water, could more accurately be used to predict and screen for JSC quality outcomes. The internal cake temperature profile BPV was better correlated with hand folded JSC quality than the STD 1 profile when using sucrose solvent.
Significance and Novelty
This research identified that the RVA BPV employing the internal cake temperature profile, and a 50% sucrose solvent could estimate hand folded JSC quality using less flour and taking less time than a bake test.

Ancient grains like einkorn, emmer, and spelt remain underutilized and underexplored, limiting their market potential. This study evaluates the chemical composition, rheology, pasting, and baking properties of spring growth habit einkorn, emmer, and spelt cultivars grown in the Canadian prairies compared to wholemeal and refined hexaploid wheat.
Findings
Einkorn cultivars (CDC Aixe and CDC Marval) had inferior dough mixing properties and the lowest bread loaf volume. CDC Tatra (emmer) bread had a significantly (p < .05) higher specific volume (3.32 mL/g) than Canada Western Red Spring (CWRS) wholemeal bread.
Conclusions
Results from mixing and baking indicate that emmer and spelt cultivars have the potential to be used in breadmaking applications, while einkorn cultivars with suboptimal properties need ingredient technology and process modifications to improve their functionalities.
Significance and Novelty
The study was able to identify and characterize an emmer cultivar (CDC Tatra) with excellent mixing and baking properties having the potential as a standalone flour for baking applications. This represents a significant advancement, as prior research had not recognized any emmer cultivars for their suitability in baking. Our results highlight that cultivar-based assessment is essential in evaluating the end-use quality of ancient grain species, thereby developing products using such underutilized grains.
古老的谷物，如玉米、二粒小麦和斯佩尔特小麦，仍然没有得到充分利用和开发，限制了它们的市场潜力。本研究比较了生长在加拿大草原上的小麦品种的化学成分、流变学、糊化和烘烤特性，并将其与全麦小麦和精制六倍体小麦进行了比较。结果Einkorn品种（CDC Aixe和CDC Marval）的面团混合性能较差，面包体积最低。CDC Tatra （emmer）面包的比体积（3.32 mL/g）显著高于加拿大西部红泉（CWRS）全麦面包（p < 0.05）。结论混合和烘焙结果表明，emmer和spelt品种具有用于面包制作的潜力，而性能不理想的einkorn品种需要通过成分技术和工艺改造来提高其功能。该研究能够鉴定和表征一种具有优异混合和烘焙性能的二聚体品种（CDC Tatra），具有作为烘焙应用的独立面粉的潜力。这代表了一个重大的进步，因为以前的研究没有认识到任何二聚体栽培品种适合烘烤。我们的研究结果强调，基于品种的评估对于评估古代谷物物种的最终利用质量至关重要，从而开发利用这些未充分利用的谷物的产品。

Background and Objectives
The molecular interactions in naked oat flour are crucial to its processing quality. To investigate interaction mechanisms during oat-food Sanshu thermal processing, this study analyzed starch structure properties, rheological properties, and interactions between starch and other components in naked oat flour.
Findings
The rheological and pasting properties of oat starch were closely related to its structure during different thermal stages. X-ray diffraction revealed the formation of amylose–lipid complexes, and the starch–lipid/starch–protein interactions were confirmed by specific functional groups from Fourier transform infrared spectra. The formation of complexes during roasting thermal treatment significantly increased G′ and G″, while the decomposition of starch during boiling and steaming thermal treatment reduced the rheological properties. SEM showed the dispersion and decomposition of starch, which further provided evidence for the interaction of starch and other components during Sanshu processing. The digestibility increased gradually, as the starch gelatinized during Sanshu processing. During steaming thermal treatment, RDS did not change significantly, while SDS transformed into RS (RS content increased to 9.36%).
Conclusions
The interaction of starch–lipids/starch–protein occurred during oat-food Sanshu thermal processing. The alterations in the rheological and pasting properties of naked oat flour were observed to be intimately linked to these complexes.
Significance and Novelty
The structure of naked oat flour is closely related to its processing quality. The observed changes in starch short-range order and the formation of a microcrystalline structure are closely related to RS, which can be used as a signal of interaction-resistant starch formation.

Flour quality is a key target of hard winter wheat breeding. The Farinograph is important for assessing quality before cultivar release in the United States, but large sample size requirements and long test times render it impractical for early-stage selection relative to the GlutoPeak. To improve GlutoPeak utility for breeding, we calculated new parameters from device raw output and used random forest regression to predict key Farinograph parameters in a winter wheat population containing wild relative introgressions.
Findings
The key quality parameters of absorption, bake absorption, tolerance stability, and mixing tolerance index were moderately well predicted (R2 ranging from 0.488 to 0.745). Classification of samples as acceptable or unacceptable for mixing tolerance index and tolerance stability was more accurate than prediction of numeric values.
Conclusions
New features calculated from the GlutoPeak raw data were useful predictors of quality. Prediction accuracies are sufficient to improve breeding populations.
Significance and Novelty
This study is the first to use wheat wild relative introgressions in GlutoPeak Farinograph prediction, the first to generate features from raw data, and is one of the few random forest models for quality prediction. The tools that we provide will improve ability to cull poor-quality lines early in the breeding pipeline can support efficient wheat cultivar development.

Background and Objectives
Rice bran is a source of bioactive polyphenols. This study aimed to characterize the antidiabetic potential of different rice brans (one brown, two red, and two purple) by examining their ability to inhibit α-amylase, α-glucosidase, and pancreatic lipase, and to stimulate glucose uptake in adipocytes.
Findings
All pigmented bran extracts significantly inhibited α-glucosidase. Both red rice brans inhibited α-amylase close to 50% at the highest dose tested. All four pigmented rice brans inhibited lipase in vitro (IC50 values 4.38–10.09 mg/mL). The pigmented rice brans studied contained higher levels of total polyphenolic content (TPC), total flavonoid content (TFC), and antioxidant capacity when compared to brown rice bran. Purple bran contained anthocyanins and red brans contained proanthocyanidins. The pigmented brans consisted of higher levels of total benzoic acids, while the brown rice bran had higher levels of total cinnamic acids. Tricin was identified in all pigmented brans.
Conclusions
Our study indicates that pigmented rice brans have the ability to manage obesity and diabetes due to their inhibitory effects on lipid and carbohydrate digestion. Several bioactive polyphenols were identified.
Significance and Novelty
The potential of pigmented rice bran to inhibit α-amylase, α-glucosidase, and lipase was confirmed.

Conventional pulse starch extraction methods face challenges in terms of yield, purity, and recovery. The native starches after extraction often undergo modification for broader applications. Ultrasound is considered a promising approach for starch extraction and modification due to its unique principle and reduced processing times. This work addresses the effects of ultrasound-assisted methods on extraction and characteristic modification of pulse starches.
Findings
The cavitation effect of ultrasound effectively disrupts starch–protein interactions, improves diffusion, and significantly increases the pure starch yield. When applied to starch modification, it impacts surface morphology, amylose, and amylopectin chains resulting in notable changes to the characteristic behavior. Dual modification by combining ultrasound with other methods could allow for customized starch characteristics through structural reorganization, cross-linking, and depolymerization.
Conclusions
The increased yields and modified properties of pulse starches through ultrasound-assisted methods could enable their utilization in a wide range of food and nonfood applications.
Significance and Novelty
This review provides new insights into the extraction and modification of pulse starches through ultrasound-assisted methods. It benefits researchers, food and starch industries, in selecting appropriate processing methods based on yield and specific properties of pulse starches required for their intended applications.

Background and Objectives
Although bread waste is often processed into breadcrumbs for use in breading formulations, an alternative method to add value to this by-product is to incorporate it into snack food applications. This study examined the extrusion of breadcrumbs under varying conditions of feed moisture content (13%, 15%, or 17%) and die temperature (120°C or 150°C). To enhance the total dietary fiber (TDF) content of the extrudates, the base breadcrumbs formula was supplemented with resistant starch types 2 and 4 (RS2 and RS4) at different concentrations (15% and 30%). The physical and techno-functional properties of the resulting breadcrumb extrudates (BCEs) were then investigated.
Findings
The TDF content of BCEs generally increased with higher feed moisture contents, but it was not affected by different die temperatures. The highest radial expansion index (6.33) among the RS-supplemented BCEs was achieved with RS2-supplemented BCEs extruded at a die temperature of 120°C and a feed moisture content of 13%. RS4 supplementation also produced BCEs with similar properties under certain extrusion conditions.
Conclusions
There was no significant difference in TDF content between RS2 and RS4-supplemented BCEs at the lowest feed moisture content studied. Overall, RS2 supplementation had a less negative impact on the extrudate expansion index, density, and crispness values compared to RS4 supplementation, indicating the better suitability of RS2 for snack food applications. All BCEs produced had TDF contents higher than 6%, allowing them to carry a “high fiber content” claim according to relevant European Union regulations.
Significance and Novelty
The effects of different types of resistant starch on the physical and techno-functional properties of extruded snacks have not been studied to date. This study addresses this research gap and adds value to a major by-product of the bakery industry, breadcrumbs, by incorporating them into snack food applications.

Background and Objective
The interaction between starch and polyphenol would increase the bioaccessibility of those bioactive compounds. Previous studies have been conducted with pure polyphenols, but the use of medicinal plants, rich in bioactive compounds, able to complex with starch, is growing. The present study aimed to analyze the complex formation between the extract of a medicinal plant (Amphipterygium adstringent, AA) and high amylose starch (HA). The total polyphenol content (TPC), and antioxidant capacity (AC), besides X-ray diffraction pattern, differential scanning calorimetry, Fourier transform infrared spectroscopy (FTIR), and starch hydrolysis rate were evaluated in the AA-HA and compared with those of the complex gallic acid (GA)-HA.
Findings
The AA-HA complex had higher TPC than GA-HA, despite their rather similar AC. The increased crystallinity and short-range order of the HA confirmed the formation of the complex with AA. This complex required higher enthalpy (2.0 J/g) than its respective HA control (0.52 J/g) for the gelatinization and the in vitro starch hydrolysis suggests the formation of resistant starch.
Conclusion
The extract of medicinal plants can form complexes with amylose, which has antioxidant properties, besides increasing the resistant starch.
Significance and Novelty
Complex formation between HA and extract of medicinal plants is feasible for increasing the release of the bioactive compounds after digestion.

Background and Objective
Corn and soybean meal are important ingredients for livestock and poultry feed. Feed producers who wish to produce non-genetically modified (non-GM) feed must segregate ingredients, especially corn and soybeans, throughout the supply chain. All supply chain participants must apply segregation practices to minimize the allowable presence of GM material, termed adventitious presence (AP), in non-GM product loads. All these actions and processes raise concerns about production costs. The approach of this study was to model the feed supply chain segregation costs at country grain elevators, focusing on non-GM corn and soybeans. To estimate the costs of successfully reaching four specified tolerance levels (0.9%, 1.5%, 3.0%, and 5.0%), 24 scenarios were constructed and evaluated using the Monte Carlo simulation method. Input variables were drawn from previous literature findings on segregation within the grain elevator environment and the costs of segregation actions. These variables included costs for new or dedicated equipment construction, testing costs, segregation method, facility capacity, and cleaning approaches. Scenarios were categorized by segregation method and facility capacity.
Findings
According to the model, the grain elevator was expected to spend an additional $0.03 to $0.04 per bushel to handle and segregate non-GM soybeans as compared with GM soybeans and an additional $0.07 to $0.08 per bushel to successfully segregate non-GM corn.
Conclusion
Grain elevators are expected to spend an additional $0.03 to $0.04 per bushel to successfully handle and segregate non-GM soybeans as compared with GM soybeans. Costs to successfully handle and segregate non-GM corn were an additional $0.07 to $0.08 per bushel.
Significance and Novelty
The study provides cost estimates for segregating non-GM corn and soybeans in a grain elevator. When non-GM corn and soybeans are used as part of feed ingredients, feed costs will increase.
