Starch-based particles as stabilizers for Pickering emulsions: modification, characteristics, stabilization, and applications.

The potential utilization of starch as a particle-based emulsifier in the preparation of Pickering emulsions is gaining interest within the food industry. Starch is an affordable and abundant functional ingredient, which makes it an excellent candidate for the stabilization of Pickering emulsions. This review article focuses on the formation, stabilization, and properties of Pickering emulsions formulated using starch-based particles and their derivatives. First, methods of isolating and modifying starch-based particles are highlighted. The key parameters governing the properties of starch-stabilized Pickering emulsions are then discussed, including the concentration, size, morphology, charge, and wettability of the starch-based particles, as well as the type and size of the oil droplets. The physicochemical mechanisms underlying the ability of starch-based particles to form and stabilize Pickering emulsions are also discussed. Starch-based Pickering emulsions tend to be more resistant to coalescence than conventional emulsions, which is useful for some food applications. Potential applications of starch-stabilized Pickering emulsions are reviewed, as well as recent studies on their gastrointestinal fate. The information provided may stimulate the utilization of starch-based Pickering emulsions in food and other industries.

Green leaf proteins: a sustainable source of edible plant-based proteins.

The rise in the global population, which is projected to reach 9.7 billion by 2050, has resulted in an increased demand for proteins in the human diet. The green leaves of many plants are an affordable, abundant, and sustainable source of proteins suitable for human consumption. This article reviews the various sources of green leaf proteins that may play an important role in alleviating global malnutrition, including those from alfalfa, amaranth, cabbage, cassava, duckweed, moringa, olive, radish, spinach, sugar beet, and tea. The structure of green leaves and the location of the proteins within these leaves are described, as well as methods for extracting and purifying these proteins. The composition, nutritional profile, and functional attributes of green leaf proteins are then discussed. The potential advantages and disadvantages of using green leaf proteins as functional food ingredients are highlighted. The importance of obtaining a better understanding of the composition and structure of different green leaves and the proteins extracted from them is highlighted. This includes an assessment of non-protein nitrogen and anti-nutritional compounds that may be present. Furthermore, the impact of isolation and purification techniques on the functionality of the plant protein ingredients obtained must be carefully evaluated.

Amaranth proteins: From extraction to application as nanoparticle-based delivery systems for bioactive compounds.

Amaranth proteins can be produced more sustainably than animal proteins, and they have amino acid compositions that are nutritionally balanced, which makes them attractive candidates for various applications in the food and pharmaceutical industries. This article provides an overview of the composition and techno-functional properties of amaranth protein, including its solubility, emulsification, gelation, foaming, and binding properties. These properties play an important role in the use of amaranth proteins for formulating nanoparticle-based delivery systems with good functional attributes. Amaranth proteins have structural and physicochemical properties suitable for fabricating protein-based nanoparticles. These nanoparticles can be used to encapsulate and control the release of bioactive compounds. However, challenges associated with the presence of anti-nutritional factors in amaranth proteins need to be addressed. These antinutrients negatively affect the bioavailability and digestibility of proteins and bioactive compounds. Hence, strategies to mitigate these challenges are discussed, including processing technologies and genetic engineering methods.

Evaluating the traditional bread properties with new formula: Affected by triticale and cress seed gum.

During recent years, composite bread is more popular among consumers due to its functional and nutritional properties. Among cereals, triticale has been studied, along with careful observation of its characteristics. In addition, hydrocolloids can be replaced as an appropriate resource due to a decrease in the gluten content. The present study aimed to evaluate the effect of triticale flour replacement at the levels of 0, 100, 150, and 250 g/kg, and cress seed gum at the concentrations of 0, 3, 6, and 10 g/kg on the rheological parameters of dough and physicochemical, textural, microstructural, and sensory properties of bread. Based on the results, formula including composite flour (150 g/kg triticale flour+850 g/kg wheat flour) and cress seed gum at 6 g/kg was the best formulation for improving the texture, color parameters, and general acceptance of both types of bread (Barbari and Lavash). Regarding the Iranian Barbari bread, cress seed gum increased the specific volume, porosity, and brightness, while reduced the hardness compared to the control. Besides, sensory evaluation manifested that 150 g/kg of wheat flour could be replaced with triticale flour for providing a good quality of bread. In conclusion, the addition of 150 g/kg of triticale and 6 g/kg of cress seed gum into composite flour and bread formulations had positive effects on all properties measured in both types of bread.
