Coix seed (Coix lachryma-jobi L.) is an important nourishing food and traditional Chinese medicine. The role of their bioactive constituents in physiology and pharmacology has received considerable scientific attention. However, very little is known about the role of coix seed bioactive components in the growth of Limosilactobacillus reuteri (L. reuteri). This study aimed to evaluate the effects of coix seed extract (CSE) on the growth, acidifying activity, and metabolism of L. reuteri. The results showed that CSE can increase the growth and acidifying activity of L. reuteri compared with the control group. During the stationary phase, the viable bacteria in the medium supplemented with coix seed oil (CSO, 13.72 Log10 CFU/mL), coix polysaccharide (CPO, 12.24 Log10 CFU/mL), and coix protein (CPR, 11.91 Log10 CFU/mL) were significantly higher (p < 0.05) than the control group (MRS, 9.16 Log10 CFU/mL). CSE also enhanced the biosynthesis of lactic acid and acetic acid of L. reuteri. Untargeted metabolomics results indicated that the carbohydrate metabolism, amino acid metabolism, and nucleotide metabolism activities of L. reuteri were increased after adding CSE. Furthermore, CSE increased the accumulation of bioactive metabolites, such as phenyl lactic acid, vitamins, and biotin. Overall, CSE may have prebiotic potential and can be used to culture L. reuteri with high viable bacteria.

“…This agreed with the ndings of Chauhan et al, 22 who also reported that M2 and M3 were the predominant MOS produced from coffee extract using a Bacillus nealsonii PN-11 b-mannanase. Wongsiridetchai et al 11,15 also reported that SCG hydrolysis, using a Bacillus sp. GA2 (1) mannanase, results in M2 and M3 as the predominant products.…”

“…Nguyen et al 2 also demonstrated that enzymatic hydrolysis of delignied and defatted SCG resulted in mannobiose (M2) and mannohexaose (M6) as the predominant sugars produced. Wongsiridetchai et al 11,15 demonstrated that enzymatic hydrolysis of pretreated SCG using a Bacillus subtilis GA2 (1) derived mannanase resulted in the production of M2 and mannotriose (M3) as predominant sugars. The MOS produced from both studies enhanced the growth of benecial bacteria, such as Lactobacillus acidophilus, L. casei and L. plantarum.…”

“…were obtained under optimal conditions (1:23 solid/water ratio, 213 W ultrasound power, 30 min extraction and 68 °C extraction temperature). Wongsiridetchai and collaborators [ 102 ] characterized the mannooligosaccharides obtained from SCG and evaluated their prebiotic properties. SCGs were submitted to an alkali treatment with NaOH and then digested by mannanase from Bacillus subtilis GA2.…”

Current estimates place the amount of spent coffee grounds annually generated worldwide in the 6 million ton figure, with the sources of spent coffee grounds being classified as domestic (i.e., household), commercial (i.e., coffee houses, cafeterias and restaurants), and industrial (i.e., soluble and instant coffee industries). The majority of the produced spent coffee grounds are currently being inappropriately destined for landfills or to a form of energy recovery (e.g., incineration) as a refuse-derived fuel. The disposal of spent coffee in landfills allows for its anaerobic degradation with consequent generation and emission of aggressive greenhouse gases such as methane and CO2, and energy recovery processes must be considered an end-of-life stage in the lifecycle of spent coffee grounds, as a way of delaying CO2 emissions and of avoiding emissions of toxic organic volatile compounds generated during combustion of this type of waste. Aside from these environmental issues, an aspect that should be considered is the inappropriate disposal of a product (SCG) that presents unique thermo-mechanical properties and textural characteristics and that is rich in a diversity of classes of compounds, such as polysaccharides, proteins, phenolics, lipids and alkaloids, which could be recovered and used in a diversity of applications, including food-related ones. Therefore, researchers worldwide are invested in studying a variety of possible applications for spent coffee grounds and products thereof, including (but not limited to) biofuels, catalysts, cosmetics, composite materials, feed and food ingredients. Hence, the aim of this essay was to present a comprehensive review of the recent literature on the proposals for utilization of spent coffee grounds in food-related applications, with focus on chemical composition of spent coffee, recovery of bioactive compounds, use as food ingredients and as components in the manufacture of composite materials that can be used in food applications, such as packaging.
