“…Likewise, the intake of tryptophan has been associated with increased melatonin concentration in plasma [49]. Lentils are considered a source of tryptophan, both protein-bound and free [50]. Lentil sprout intake led to comparable increases of melatonin plasmatic concentration as those reported after walnut ingestion [51].…”

Melatonin is a multifunctional antioxidant neurohormone found in plant foods such as lentil sprouts. We aim to evaluate the effect of lentil sprout intake on the plasmatic levels of melatonin and metabolically related compounds (plasmatic serotonin and urinary 6-sulfatoxymelatonin), total phenolic compounds, and plasmatic antioxidant status, and compare it with synthetic melatonin. The germination of lentils increases the content of melatonin. However, the phenolic content diminished due to the loss of phenolic acids and flavan-3-ols. The flavonol content remained unaltered, being the main phenolic family in lentil sprouts, primarily composed of kaempferol glycosides. Sprague Dawley rats were used to investigate the pharmacokinetic profile of melatonin after oral administration of a lentil sprout extract and to evaluate plasma and urine melatonin and related biomarkers and antioxidant capacity. Melatonin showed maximum concentration (45.4 pg/mL) 90 min after lentil sprout administration. The plasmatic melatonin levels increased after lentil sprout intake (70%, p < 0.05) with respect to the control, 1.2-fold more than after synthetic melatonin ingestion. These increments correlated with urinary 6-sulfatoxymelatonin content (p < 0.05), a key biomarker of plasmatic melatonin. Nonetheless, the phenolic compound content did not exhibit any significant variation. Plasmatic antioxidant status increased in the antioxidant capacity upon both lentil sprout and synthetic melatonin administration. For the first time, we investigated the bioavailability of melatonin from lentil sprouts and its role in plasmatic antioxidant status. We concluded that their intake could increase melatonin plasmatic concentration and attenuate plasmatic oxidative stress.

“…The protein content of faba bean ranges from 24% to 35% of the seed dry matter [2], with an average of 29% [3], making it the most protein-rich major pulse crop [4]. It is relatively high in lysine, which is an essential amino acid in human and monogastric diets [5]. In addition to being an excellent source of protein and starch, it contains valuable mineral micronutrients [2].…”

Two-thirds of the world’s population are at risk of deficiency in one or more essential mineral elements. The high concentrations of essential mineral elements in pulse seeds are fundamentally important to human and animal nutrition. In this study, seeds of 25 genotypes of faba bean (12 low-tannin and 13 normal-tannin genotypes) were evaluated for mineral nutrients and protein content in three locations in Western Canada during 2016–2017. Seed mineral concentrations were examined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and the protein content was determined by Near-Infrared (NIR) spectroscopy. Location and year (site-year) effects were significant for all studied minerals, with less effect for calcium (Ca) and protein content. Genotype by environment interactions were found to be small for magnesium (Mg), cobalt (Co), Ca, zinc (Zn), and protein content. Higher seed concentrations of Ca, manganese (Mn), Mg, and cadmium (Cd) were observed for low-tannin genotypes compared to tannin-containing genotypes. The protein content was 1.9% higher in low-tannin compared to tannin-containing genotypes. The high estimated heritability for concentrations of seed Mg, Ca, Mn, potassium (K), sulphur (S), and protein content in this species suggests that genetic improvement is possible for mineral elements.

“…Pulses are versatile crops due to their notable compositions, which consist of high protein contents, complex carbohydrates (starch, nonstarch oligosaccharides, and dietary fiber), minerals, vitamins, and phytochemicals (9,10,13,21,22). The high protein contents of peas (14-31%), lentils (21-31%), and faba beans (19-39%) are regarded as important plant-protein sources and a good fit for value-added ingredients that meet human protein intake needs (10,11,14,23,24). Pulse proteins (Table I) are composed of major storage proteins, including globulins (soluble in salt solutions) and albumins (soluble in water) and minor proteins such as prolamins (soluble in alcohol) and glutelins (soluble at dilute acid or base solution) (10,11,12,14,23,24).…”

“…(Lens culinaris), and faba bean (Vicia faba). Pulse proteins can provide an alternative to soybean proteins as they are low in allergens, are non-GMO protein sources, and have similar amino acid attributes and digestibility scores compared with soybean proteins (1,3,7,9,11,14,17,19). Furthermore, promising techno-functionality attributes (e.g., solubility, gelling, waterbinding, and texturizing properties) of pulse proteins can provide additional benefits in food formulation systems (1,3,5,9,10,20).…”

Low- and High-Moisture Extrusion of Pulse Proteins as Plant-Based Meat Ingredients: A Review

Plant-based meat alternatives have become a major staple in the North American marketplace due to changing consumer demands. The main drivers of this market segment are changing dietary patterns, increasing numbers of consumers pursuing vegetarian and flexitarian lifestyles, rising individual income in developing countries, and an increase in global awareness of environmental concerns. Pulse crops and pulse proteins present an outstanding nutritional value chain, along with superior techno-functionality that can meet the requirements of plant proteins for producing meat analogue ingredients. In addition, pulse crops can assist in reducing carbon footprint by fixing nitrogen during agricultural production rotations. Pulse proteins also offer alternative solutions for addressing gluten-free, low-allergen, and GMO-free meat alternatives in the global marketplace. Alternative pulse-based solutions with similar sensory and texture attributes may be used to substitute for meat ingredients in new product applications. Global awareness of healthy lifestyles, increased protein intake, and rising income in developing countries have shifted eating habits toward following a well-balanced diet that consists of a complete combination of proteins, carbohydrates, lipids, and micronutrients (1). As the world population has been predicted to reach 9.5 billion by 2050, the demand for animal proteins would significantly increase due to changing consumption patterns in Asian and Southeast Asian countries (2). However, increased demand for animal-based products and their higher consumption levels may have negative impacts on the nutritional health of consumers and the environmental health of the planet (2-4). Particularly, increased use of animal-based proteins may increase carbon footprint, water consumption, and contribute to increased greenhouse gas formation. Alternative vegetable-based proteins can be considered to reduce these negative impacts and help food manufacturers develop sustainable solutions (3). Meat production has significantly increased in the United States, with 87,409 million pounds produced by November 2019 (8). The global demand for animal-based proteins has been rising as well and is expected to reach twice its current level by 2050 (2). However, the animal protein production industry may negatively affect a sustainable environment and human health. Additionally, the dietary restrictions of various cultures and high cost of animal-based proteins may limit the consumption of animal-based products (5). Thus, a new generation of North American consumers has recently started following a more sustainable and eco-friendly plant-based protein consumption pattern that 1) consumes low-cholesterol, low-fat, high-protein, and high-dietary fiber foods; 2) contributes to a sustainable food supply; 3) contributes to a reduction in pollution and ecological footprint; and 4) assists in the reduction of water consumption in the food production chain (1,2,5-7). Scientists have been conducting research on alternative protein resou...
