Physicochemical, nutraceutical, and sensory evaluation of a milk-type plant-based beverage of extruded common bean (Phaseolus vulgaris L.) added with iron.

Milk-type beverages are popular vegan products requiring iron and calcium fortification to improve their nutritional value, as iron deficiency is the world's most prevalent nutritional problem. This research aimed to develop and characterize an extruded common bean (Phaseolus vulgaris L.)-based milk-type beverage added with bean protein isolate and iron. The formulations included flavors (non-flavored, vanilla, and nut) and two iron concentrations (2 and 3 mg FeSO4/100 mL). Extrusion increased the beverages' protein (+17.38 %) and starch digestibility, and reduced their antinutritional compounds (trypsin inhibitors, condensed tannins, and carbonates). Developed beverages' formulations differed from a commercial soybean beverage in their physicochemical properties but were more nutritious (protein: 3.33-3.44 %; fiber: 3.43-4.08 %). Iron-added beverages displayed a medium sensory acceptance (best overall likeness: 5.3-6.2). The developed beverage is a suitable, sensory-accepted, and nutritious bean-based beverage, suggesting novel research lines improving vegan beverage formulations to increase average daily iron intake.

Nutritional and Nutraceutical Properties of Selected Pulses to Promote Gluten-Free Food Products.

The market for gluten-free products is increasing with an estimated 7.6% annual growth rate from 2020 to 2027. It has been reported that most gluten-free products, such as bread, cookies, and pasta, contain great amounts of simple carbohydrates and are low in fiber and protein, affecting people's health. Pulses such as common beans, chickpeas, lentils, and peas have been studied as an alternative for developing gluten-free products because of their high protein and fiber content. In addition, they contain bioactive compounds with nutraceutical properties, such as phenolics, saponins, dietary fiber, and resistant starch, among others. Most studies carried out with pulses in vitro and in vivo have displayed health benefits, proving that pulse-based food products are better than their counterparts, even those containing wheat, with proper sensory acceptance. This work reviews pulse's nutritional and nutraceutical properties to promote the development and consumption of gluten-free products and improve their formulations to promote people's health.

Avocado seed by-product uses in emulsion-type ingredients with nutraceutical value: Stability, cytotoxicity, nutraceutical properties, and assessment of in vitro oral-gastric digestion.

The avocado industry obtains 20-30% of the total by-products (peels and seeds). However, byproducts can be uses as sources of economic nutraceutical ingredients with functional potential. This work developed emulsion-type ingredients from avocado seed to evaluate its quality, stability, cytotoxicity, and nutraceutical properties before/after in vitro oral-gastric digestion. Ultrasound lipid extraction achieved an extraction yield of up to 95.75% compared with Soxhlet conventional extraction (p > 0.05). Six ingredients' formulations (E1-E6) were stable for up to day 20 during storage, preserving their antioxidant capacity and displaying low in vitro oxidation compared to control. None of the emulsion-type ingredients were considered cytotoxic according to the shrimp lethality assay (LC50 > 1000 µg/mL). Ingredients E2, E3, and E4 generated low lipoperoxides' concentrations and high antioxidant capacity during the oral-gastric stage. The 25 min-gastric phase showed the highest antioxidant capacity and low lipoperoxidation. Results suggested avocado seed-derived could be used to develop functional ingredients with nutraceutical properties.

Prediction of the Physicochemical and Nutraceutical Characteristics of 'Hass' Avocado Seeds by Correlating the Physicochemical Avocado Fruit Properties According to Their Ripening State.

Vegetal wastes are currently a source of pollution due to the excess of organic compounds in the environment. Seeds are the main by-product of the avocado industry and represent 16-22% of the total weight and it is considered a waste without applications. Despite the seed stands out for its high content of phenolic compounds, lack of knowledge regarding of the best processing state using non-invasive and short-time methods are required to take advantage of these nutraceutical compounds. This research aimed to find correlations from physicochemical analysis, color, hardness, and firmness of the whole avocado seeds with its nutraceutical properties as long as the ripeness increased, providing information for further industrial use of this waste. The results indicated that 'Hass' avocado fruit ripening positively correlates with the improvement of the physicochemical parameters involved in the fruit processing and the increase of nutraceutical compounds in the seed. The ripeness process decreased moisture (%) and hardness (N) parameters in the seeds (27.69 and 16.4%, respectively), facilitating its processing. Moreover, the ripening increased the antioxidant capacity by DPPH* around 7%, due to the concentration of phenolic compounds in the seed. Seed's phenolic compounds were positively correlated with the Hue angle at increasing ripeness, becoming a potential physicochemical indicator for the industry. The prediction of changes in nutraceutical compounds and physicochemical properties, as ripening occurred, may reduce analysis times, processes, and guidance to use avocado seeds as a by-product. These results facilitate the seed processing and open up opportunities for its use in the industry.
