Thus, this study aimed to assess the physicochemical and phytochemical parameters, biological activities, and nutritional value of the two pollen types: Pure date palm pollen and date palm pollen crushed with its spadix. Various physicochemical parameters were determined, including humidity, water activity (<i>a</i><sub>w</sub>), total soluble solids, ash content, and color parameters (<i>L*</i>, <i>a*</i>, <i>b*</i>, <i>C*<sub>ab</sub></i>, and <i>h<sub>ab</sub></i>). Additionally, the phenolic compound profiles were analyzed, and the <i>in vitro</i> antioxidant, enzyme inhibitory, and antidiabetic activities were assessed for both pure date palm pollen and date palm pollen crushed with its spadix. Furthermore, the nutritional value was evaluated by determining protein and carbohydrate contents, and mineral and fatty acid profiles. The results have revealed that pure date palm pollen had higher humidity, a<sub>w</sub>, <i>L*</i>, and <i>h<sub>ab</sub></i> color parameters than date palm pollen crushed with its spadix, but lower total soluble solid and ash contents. The main phenolic compounds in pure date palm pollen were ellagic acid, rutin, fisetin, and quercetin, whereas date palm pollen crushed with its spadix contained mainly catechin, chlorogenic acid, <i>p</i>-coumaric acid, ferulic acid, and rutin. Moreover, pure date palm pollen showed greater <i>in vitro</i> antioxidant activity, while date palm pollen crushed with its spadix had higher enzyme inhibitory and antidiabetic activities. PDPS was the richest source of proteins, carbohydrates, minerals, and saturated fatty acids, while date palm pollen crushed with its spadix was a better source of unsaturated fatty acids, which are mainly represented by linoleic acid. In conclusion, although date palm pollen crushed with its spadix is the most widely consumed type, its nutritional value is lower than that of pure date palm pollen.

In this study, sorghum and germinated lima bean flour (100, 90:10, 80:20, 70:30, 60:40 and 50:50) was extruded (feed moisture - 18%, screw speed - 250 rpm, barrel temperatures 50 °C-120 °C-120 °C, die hole diameter - 3 mm) and analysed for functional, proximate, textural, structural, pasting, microbiological and sensory properties. With 100% sorghum used as control, lima beans addition significantly (p < 0.05) improved the loose (0.37-0.44 g/ml) and packed (0.63-0.72 g/ml) bulk density, while water (5.00-3.15 g/g) and oil (2.45-1.60 g/g) absorption capacity and expansion ratio (3.11-2.30) decreased, respectively. An increase in protein (12.77-18.00%), crude fibre (2.58-5.17%) and ash content (2.11-3.12%) were observed in the extrudate, while the (<i>L*</i>) colour parameter (54.49-43.62), hardness (180.04-78.36 N) and pasting viscosities reduced with addition of lima beans. The structural micrograph depicted air-trapped bubbles with thick walls after adding lima beans, while a notable decline in microbial count below approved limits was observed after 8 weeks of storage. Sensory scores showed that values obtained were above average with the 90:10 sorghum-lima bean ratio having the highest score. The economic and industrial value of underutilised legumes such as lima bean can be promoted as functional ingredients via extrusion in addressing coeliac disease and alternative sources of protein, especially in developing countries.</p>","PeriodicalId":12331,"journal":{"name":"Food Science and Technology International","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142461610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
