This study aimed to establish better extraction conditions of bioactive compounds from <i>Melipona</i><i> quadrifasciata</i> (MQ) propolis using a central composite rotational design (CCRD) and multivariate statistical tools. The solvent concentration and extraction time effects on the phenolic compounds profile with antioxidant activity (AA) were evaluated.

The best condition for TPC and AA was 50% ethanol and 60 min of the extraction. However, each phenolic compound identified had a different best extraction condition, probably due to the molecules’ polarity and solvent interaction. The cinnamic acid was the highest content identified, followed by ferulic acid, gallic acid, epicatechin, <i>p</i>-coumaric acid, and catechin. Anyway, more extended times of extraction and solvent concentration closer to 50% ethanol can maximise the extraction of compounds with antioxidant potential.

Principal Component Analysis (PCA) on the ATR-FTIR spectra clearly illustrated a clear separation between normal honey and SBH; and between raw SBH and processed SBH.

Saltiness index (SI) was defined as the ratio of perceived NaCl concentration to the actual NaCl concentration, and was proposed to evaluate the saltiness enchantment. Method validation of the saltiness sensor included assessments of linearity, repeatability, reproducibility, limit of detection, limit of quantitation, and recovery yield. A desirable linear relationship between the logarithm of perceived NaCl concentration and saltiness was observed at NaCl concentration ranging from 45 to 90 mM with a determination coefficient exceeding 0.99. A low relative standard deviation of less than 1% was achieved in the repeatability test. Through visual evaluation, the detection and quantitation limits of the saltiness sensor for NaCl solutions were determined to be 0.01 mM and 0.1 mM, respectively. A high recovery yield (97.6–108.3%) was obtained from the spike recovery test. Optional test solvents, including ultrapure water, distilled water, and pure water, were employed without interference. Upon adding 20–35 g/100 g potassium chloride, the salty response of the salt solution increased, while the linearity of NaCl solution remained unaffected. Saltiness enhancements of 37.20 ± 0.00% and 18.17 ± 0.18% were observed for the potassium-containing salt (30%, w/w) and oyster mushroom (<i>Pleurotus ostreatus</i>) peptides (0.3%, w/w), respectively. This evaluation method provided an effective and quantitative approach to advancing the development of salt reduction ingredients.</p></div>","PeriodicalId":561,"journal":{"name":"Food Analytical Methods","volume":"17 5","pages":"727 - 738"},"PeriodicalIF":2.6,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140026163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
