“…For many years, P. tetragonolobus or winged bean has been widely utilized in traditional medicine as it contains several bioactive compounds. It is a member of Fabaceae family and is high in protein, oils, vitamins, and carbohydrates [45]. It has been reported that winged bean seed hydrolysate is non-toxic and can stimulate cell proliferation in NIH/3T3 mouse fibroblast cells [46] and winged bean extract was non-toxic to RAW264.7 macrophage cells [47].…”

Background: Winged bean or Psophocarpus tetragonolobus (WB) seeds have high protein content and could be applied as a source of antioxidant proteins and peptides. The utilization of gamma rays in plant protein extraction provides consumers with a safe and harmless technology.Objective: To determine the efficiency of gamma rays in the protein extraction process of WB seeds and investigate the antioxidant activity, cytotoxicity, cytoprotective effect of the gamma ray irradiated WB (WB-G) seed protein hydrolysate.Methods: WB seeds were irradiated with gamma ray (WB-G) and total protein were extracted by acid-base extraction method. The total protein was further hydrolyzed with alcalase enzyme to obtain the protein hydrolysate. The antioxidant activity was evaluated by DPPH and ABTS assay. The cytotoxicity and cytoprotective effect were determined by MTT assay. The cellular reactive oxygen species was further analyzed by ACFDA assay.Results: The protein extracted from WB-G seeds showed higher protein yield and antioxidant activity than that of non-irradiated seeds. After hydrolysis with alcalase enzyme at 55°C for 6 hours, WB-G protein hydrolysate with degree of hydrolysis of 90.00±0.91% exhibited strong antioxidant activity with IC50 value of 10.30±0.02 µg/ml and 3.10±0.06 µg/ml as measured by DPPH and ABTS assay, respectively. Moreover, it showed no toxicity toward L929 mouse fibroblast cells and IPEC-J2 cell lines and can reduce the damage caused by H2O2. As determined in cellular reactive oxygen species by H2-DCFDA assay, the WB-G protein hydrolysate can reduce the level of ROS and subsequently the damage of cell by H2O2. Conclusions: This study demonstrated that gamma ray irradiation on the WB seeds can increase the protein yield and its protein hydrolysate exhibited promising antioxidant activity and cytoprotective effect on cells against H2O2 damage. It might be developed as an alternative food or feed supplement.Keywords:Psophocarpus tetragonolobus; Gamma rays; Protein hydrolysate; Antioxidant activity; Cytoprotective effect

Nutritional, functional, and bioactive properties of african underutilized legumes

et al. 2023

Globally, legumes are vital constituents of diet and perform critical roles in maintaining well-being owing to the dense nutritional contents and functional properties of their seeds. While much emphasis has been placed on the major grain legumes over the years, the neglected and underutilized legumes (NULs) are gaining significant recognition as probable crops to alleviate malnutrition and give a boost to food security in Africa. Consumption of these underutilized legumes has been associated with several health-promoting benefits and can be utilized as functional foods due to their rich dietary fibers, vitamins, polyunsaturated fatty acids (PUFAs), proteins/essential amino acids, micro-nutrients, and bioactive compounds. Despite the plethora of nutritional benefits, the underutilized legumes have not received much research attention compared to common mainstream grain legumes, thus hindering their adoption and utilization. Consequently, research efforts geared toward improvement, utilization, and incorporation into mainstream agriculture in Africa are more convincing than ever. This work reviews some selected NULs of Africa (Adzuki beans (Vigna angularis), African yam bean (Sphenostylis stenocarpa), Bambara groundnut (Vigna subterranea), Jack bean (Canavalia ensiformis), Kidney bean (Phaseolus vulgaris), Lima bean (Phaseolus lunatus), Marama bean (Tylosema esculentum), Mung bean, (Vigna radiata), Rice bean (Vigna Umbellata), and Winged bean (Psophocarpus tetragonolobus)), and their nutritional, and functional properties. Furthermore, we highlight the prospects and current challenges associated with the utilization of the NULs and discusses the strategies to facilitate their exploitation as not only sources of vital nutrients, but also their integration for the development of cheap and accessible functional foods.

“…Legume intake has also been found to be inversely associated with non-cardiovascular causes of death and overall total mortality. This is due to polyphenols that contains in legumes such as phenolic acid and flavonoids, which are known to alleviate CVD [8]. These benefits are optimal when three to four servings of legumes are consumed per day (equivalent to 375-500 g/day) [9].…”

New insights of minimum requirement on legumes (Fabaceae sp.) daily intake in Malaysia

et al. 2023

Background Despite their low energy density and high nutrient content, legumes may be under-recognised as a beneficial food for the prevention and management of obesity and related diseases, such as cardiovascular disease (CVD). This study aims to analyse the moderation effect of legume intake on the relationship between BMI and the prevalence of CVD among the Malaysian adult population. Methods This study addressed communities of urban and rural Malaysia, including adults aged between 35 and 70 years old at the baseline recruitment. A series of standardised questionnaires were used to assess legume intake, history of comorbidities and socio-demographic information. Resting blood pressure measurements and physical examinations were performed to collect blood pressure and anthropometric data. Bivariate analysis was completed to determine the association between legume intake, socio-demographic characteristics and CVD prevalence. Moderation analysis was used to quantify the moderation effect of minimum daily legume intake on the relationship between BMI and CVD prevalence. Results This study found that those who consume less than 3 servings of legumes per day benefit from protective effects against CVD risk (POR = 0.56, 95% CI = 0.37 – 0.85). Moderation analysis of a minimum of three servings/day for the relationship between BMI and CVD prevalence showed significant effects. The group that benefited the most from this effect was those with a BMI in the range of 26 to 34 kg/m2. Conclusions This study provides new insights into the recommendation for legume intake according to the relationship between BMI and the prevalence of CVD in Malaysian adults. This study recommends that those with a BMI of 26 to 34 kg/m2 should consume at least 3 servings of legumes per day to reduce the risk of CVD. Further prospective research is warranted to affirm these findings throughout the Malaysian population.
