Coffee is consumed not just for its flavor, but also for its health advantages. The quality of coffee beverages is affected by a number of elements and a series of processes, including: the environment, cultivation, post-harvest, fermentation, storage, roasting, and brewing to produce a cup of coffee. The chemical components of coffee beans alter throughout this procedure. The purpose of this article is to present information about changes in chemical components and bioactive compounds in coffee during preharvest and postharvest. The selection of the appropriate cherry maturity level is the first step in the coffee manufacturing process. The coffee cherry has specific flavor-precursor components and other chemical components that become raw materials in the fermentation process. During the fermentation process, there are not many changes in the phenolic or other bioactive components of coffee. Metabolites fermented by microbes diffuse into the seeds, which improves their quality. A germination process occurs during wet processing, which increases the quantity of amino acids, while the dry process induces an increase in non-protein amino acid γ-aminobutyric acid (GABA). In the roasting process, there is a change in the aroma precursors from the phenolic compounds, especially chlorogenic acid, amino acids, and sugars found in coffee beans, to produce a distinctive coffee taste.

Vinegar is a liquid product produced from alcoholic and acetous fermentation. Vinegar contains acetic acid and bioactive compounds, which are brewed by liquid-state and solid-state fermentation techniques. This study reviews chemical fermentation process properties, bioactive compounds, and health benefits of fruit vinegars in Thailand. Chemical properties are the alcohol percentage and acetic acid percentage of vinegar. Bioactive compounds include antioxidant activity and total phenolic content, which have the role of antioxidative activity, blood pressure and glucose control, and anti-tumor. However, further studies are needed to find the new fruit raw materials to produce fruit vinegar which have more bioactive compound and more good taste.

The southern coast of Peru presents a wide diversity of seaweed, which could be used as a new sustainable source of nutritional and bioactive compounds. For the first time, we chemically characterized two species of brown (Macrocystis pyrifera) and red (Chondracanthus chamissoi) Peruvian seaweed. Both species contained significant amounts of proteins (5–12%), lipids (0.16–0.74%), carbohydrates (43.29–62.65%) and minerals (1300–1800 mg kg−1 dw: dry weight). However, the profiles of amino acids, fatty acids and minerals were highly dependent on species type. C. chamissoi had a higher content of essential amino acids and minerals than M. pyrifera (170% and 45%, respectively), while the presence of polyunsaturated fatty acids (ω 6) as well as the content of tocopherols was higher in M. pyrifera (15.77 g 100 g−1 and 2.37 μg 100 g−1, respectively). Additionally, both species presented significant concentrations of total polyphenols (39–59 mg GAE g−1) and a high antioxidant capacity (67–98 µM TE g−1). Although M. pyrifera and C. chamissoi seem to be excellent raw materials for the food and nutraceutical industry, both species contained toxic heavy metals (cadmium: Cd and nickel: Ni) which could affect the safety of their direct use. Therefore, new separation strategies that allow the selective recovery of nutrients and bioactive compounds from Peruvian seaweed are required.

In addition to soybean, Leucaena leucocephala is one of the tempe raw materials usually used in Indonesia. These tempe is only made by peoples in a few areas in the southern part of Java such as Wonogiri, Gunungkidul and Pacitan. For some purposes, such as cooking ingredients, tempe is deliberately fermented longer than usual to obtain a savory taste. In a previous study, we had studied leucaena tempe or people known as lamtoro tempe that process in Wonogiri and reported that there had been a change in characteristic during fermentation until over-fermented tempe. Therefore, in this research, we analyzed the change in the chemical and microbiological characteristic of lamtoro tempe from Pacitan during continued fermentation. This research showed that during the fermentation process, mold, yeast, and lactic acid bacteria (LAB) persisted for up to 126 hrs of fermentation time. The growth of yeast and mold tend to decrease while LAB continued to increase until it reached 11 log CFU/mL. In addition, the moisture content, ash content, soluble protein levels, pH and titrated acid increased during continued fermentation time. Glutamic acid and aspartic acid were the highest amino acids by weight percentage. Both amino acids have an important role in the sensory characteristics of lamtoro tempe.

Pitaya (Hylocereus genus) is a popular plant with exotic and nutritious fruit, which has widespread uses as a source of nutrients and raw materials in the pharmaceutical industry. However, the potential of pitaya peel as a natural source of bioactive compounds has not yet fully been explored. Recent advances in metabolomics have paved the way for understanding and evaluating the presence of diverse sets of metabolites in different plant parts. This study is aimed at exploring the diversity of primary and secondary metabolites in two commercial varieties of pitaya, i.e., green pitaya (Hylocereus undatus) and red pitaya (Hylocereus polyrhizus). A total of 433 metabolites were identified using a widely targeted metabolomic approach and classified into nine known diverse classes of metabolites, including flavonoids, amino acids and its derivatives, alkaloids, tannins, phenolic acids, organic acids, nucleotides and derivatives, lipids, and lignans. Red pitaya peel and pulp showed relatively high accumulation of metabolites viz. alkaloids, amino acids and its derivatives, and lipids. Differential metabolite landscape of pitaya fruit indicated the presence of key bioactive compounds, i.e., L-tyrosine, L-valine, DL-norvaline, tryptophan, γ-linolenic acid, and isorhamnetin 3-O-neohesperidoside. The findings in this study provide new insight into the broad spectrum of bioactive compounds of red and green pitaya, emphasizing the valorization of the biowaste pitaya peel as raw material for the pharmaceutical and food industries.

There is a growing need to recover raw materials from waste due to increasing environmental concerns and the widely adopted transition to circular economy. For waste tyres, it is necessary to continuously develop methods and processes that can devulcanize rubber vulcanizates into rubber products with qualities and properties that can closely match those of the virgin rubber. Currently, the most common, due to its efficiency and perceived eco-friendliness in recovering raw rubber from waste rubbers, such as tyres, is devulcanization in supercritical carbon dioxide (scCO2) using commercial and typical devulcanizing agents. The scCO2 has been generally accepted as an attractive alternative to the traditional liquid-based devulcanization media because of the resultant devulcanized rubber has relatively better quality than other processes. For instance, when scCO2 is employed to recover rubber from waste tyres (e.g. truck tyres) and the recovered rubber is blended with virgin natural rubber (NR) in various compositions, the curing and mechanical properties of the blends closely match those of virgin NR. The atmospheric toxicity and cost of the commonly used devulcanization materials like chemical agents, oils and solvents have enabled a shift towards utilization of greener (mainly organic) and readily available devulcanization chemical components. This literature review paper discusses the approaches, which have less negative impact on the environment, in chemical devulcanization of rubber vulcanizates. A special focus has been on thermo-chemical devulcanization of waste tyres in scCO2 using common organic devulcanizing agents.

The increase in the world population, the need to increase food production, both in quantity and quality, becomes increasingly prominent. The objective of this work was to identify the canonical correlations between yield components, morphological characters, micronutrients, bioactive compounds and amino acids in corn. The experimental design used was a randomized block containing 11 treatments arranged in three replications. The treatments consisted of 11 Top Crosses hybrid genotypes, these being made through crosses directed between a narrow genetic base tester hybrid for specific combining ability with 11 S5 inbred lines. It is inferred that groups considered yield components, secondary traits, bioactive compounds, micronutrients and amino acids are dependent. Promising characters are identified for the corn breeding for high yields, nutritional and energetic quality of corn grains. The indirect selection of grains with additions in essential amino acids can be directed to plants with superiority in height, mass and width of grains, phenols, flavonoids, soluble solids and zinc content.
