Variability in Prebiotic Carbohydrates in Different Market Classes of Chickpea, Common Bean, and Lentil Collected From the American Local Market

Abstract

Pulse crops such as lentil, common bean, and chickpea are rich in protein, low digestible carbohydrates, and range of micronutrients. The detailed information of low digestible carbohydrates also known as “prebiotic carbohydrate” profiles of commonly consumed pulse market classes and their impact on human health are yet to be studied. The objective of this study was to determine the profiles of prebiotic carbohydrates in two commonly consumed lentil market classes, seven common bean market classes, and two chickpea market classes. After removing fat and protein, total carbohydrates averaged 51/100 g for lentil, 53/100 g for common bean, and 54/100 g for chickpea. Among the portion of total carbohydrates, lentil showed 12/100 g of prebiotic carbohydrates (sugar alcohols, raffinose family oligosaccharides, fructooligosaccharides, hemicellulose, cellulose, and resistant starch), 15/100 g in common bean, and 12/100 g in chickpea. Prebiotic carbohydrate concentrations within the market classes for each crop were significantly different ( P < 0.05). In conclusion, these three pulses are rich in prebiotic carbohydrates, and considering the variation in these concentrations in the present materials, it is possible to breed appropriate market classes of pulses with high levels of prebiotic carbohydrates.

In Vitro Modulation of Gut Microbiota and Metabolism by Cooked Cowpea and Black Bean

“…Prebiotic carbohydrates are a specific colonic nutrient, comprising oligosaccharides and complex carbohydrates, which act as biosynthetic precursors for human microbiota providing subtracts for their metabolic activity. These prebiotic carbohydrates need to resist digestive processes in the upper gastrointestinal tract being fermented by intestinal microbiota, thereby selectively stimulating the growth and activity of health-promoting bacteria [34].…”

The roles and potential of lentil prebiotic carbohydrates in human and plant health

“…Lentil contains a range of prebiotic carbohydrates including average concentrations of 4,071 mg of RFOs, 1,423 mg of SAs, 62 mg of FOSs, and 7,500 mg of RS per 100 g (Johnson et al, 2013). A recent study reported the prebiotic carbohydrate profile after removing protein and fat from lentil seeds (Table 2: Siva, Thavarajah, Kumar, & Thavarajah, 2019). Among simple sugars, sucrose was the most abundant (1,174-2,288 mg/100 g) followed by glucose (21-61 mg/100 g), fructose (0.2-21.9 mg/100 g), mannose (1.2-7.9 mg/100 g), and rhamnose (0.5-1.0 mg/100 g).…”

“…When considering the impact of diet on the microbiome and chronic disease, we recommend a diet with satisfactory levels of prebiotics. Legumes, such as lentil, are a rich and affordable source of prebiotic carbohydrates with 100 g of lentil providing 12 g of prebiotic carbohydrates (Siva et al, 2019). This recommendation is especially applicable to countries where legumes are often neglected in people's diets.…”

Lantil in world and Ukraine: current state and prospects

“…Дослідження показали, що в цілому на нашій планеті 15-20% людей страждає від нестачі цього елементу, серед яких значну частку складають діти (Combs, 2001;CDC, 2016). Насіння сочевиці багате на селен (22-34 мг/г), а також на такі важливі мікроелементи як залізо (3,7-4,5 мг/г) і цинк (2,2-2,7 мг/г) (Thavarajah et al, 2011). У польових дослідженнях виявили суттєву генетичну мінливість умісту цього мікроелементу в насінні 26 сортів сочевиці із шести країн світу (Thavarajah et al, 2017).…”

Підживлення селеновим препаратом значно підвищило біомасу рослин сочевиці, що дало можливість збільшити вихід цього мікроелементу з одиниці площі.…”
