The effects of four treatments of Pleurotus eryngii (king oyster mushroom) as replacements for pork back fat were evaluated for the physicochemical, technological, and sensory properties; nitrite content; and amino acid profile in pork sausages. Five batches were manufactured: one control (formulated with pork back fat) and four treatments with raw, boiled, deep‐fried, and fried P. eryngii to replace the pork back fat in sausages. The results indicated that the fat content and energy value decreased, while the protein, moisture, total dietary fiber content, cooking loss, and water‐holding capacity of the modified sausages increased. All samples were judged acceptable for their sensory characteristics, with the best one being the sausage containing deep‐fried P. eryngii. The raw and fried P. eryngii decreased the residual nitrite content in the sausages. Boiled P. eryngii enhanced the essential amino acids content in the sausages, while the other P. eryngii treatments improved the nonessential amino acid content. In summary, P. eryngii may potentially replace fat in sausages.
Food poisoning caused by Staphylococcus aureus is responsible for staphylococcal enterotoxin (SE) produced in foods. Staphylococcal food poisoning is mostly caused by staphylococcal enterotoxin type A (SEA) among SEs. Growth/no growth for S. aureus under various environmental conditions was well studied with a logistic regression model so far. Recently we successfully described the boundaries of SEA production and growth of S. aureus in broth at various temperatures and salt concentrations with the model. In this study, the effects of lactic acid and salt on SEA production and growth of S. aureus was quantitatively studied. Consequently the boundaries of SEA production and growth of S. aureus cocktail in broth at various combinations of salt concentrations and pH values that were adjusted with lactic acid were successfully described with a logistic regression model. Here the cocktail was incubated in stationary culture at 30 °C and 10 °C. The maximum toxin production and cell growth of the cocktail were observed both at 5% salt in the pH range from 4.5 to 7.0. Also, the characteristics of individual strains of the cocktail in SEA production and growth at 30 °C and 10 °C were found to be specific to the strains. The present study revealed the effect of lactic acid and salt on SEA production and growth of S. aureus as well as the variety of SEA production and growth of S. aureus strains. These results would become useful information in food industry to prevent staphylococcal food poisoning.
Pectinase is a well‐known enzyme used in the food processing industry to produce fruit juice and concentrate. This study evaluated the anticancer and antiangiogenesis activities of pectinase‐treated Prunus mume fruit concentrate (PC) and its phenolic components. PC treatment (250 to 1,000 µg/mL) resulted in decreased proliferation of SW480 human colorectal cancer cells through S‐phase cell cycle arrest; however, equivalent concentrations of PC did not show toxicity toward CRL‐1539 colon normal cells. Furthermore, PC‐induced caspase‐dependent apoptosis in SW480 cells, which was characterized by accumulation of apoptotic cell population, cell shrinkage, formation of apoptotic bodies, upregulation of proapoptotic Bax, cleaved PARP, caspase‐3, caspase‐8, and caspase‐9, and downregulation of antiapoptotic Bcl‐2. Antiangiogenesis effects of PC were assessed using human umbilical vein endothelial cells (HUVECs). We found that PC did not inhibit HUVECs proliferation at concentrations of 500 to 1,500 µg/mL. In addition, treatment with PC at nontoxic concentrations (500 to 1,000 µg/mL) blocked vascular endothelial growth factor induced cell migration, invasion, capillary‐like tube formation, and angiogenesis from rat aortic rings. HPLC‐PDA analysis showed that there were at least four different phenolics including 5‐HMF, neochlorogenic acid, protocatechuic acid, and syringic acid. Taken together, these results indicated that PC could be used as a good source of phenolic compounds with selective anticancer and antiangiogenesis activities.
Storage temperature influences meat color stability and quality. This study was performed to quality change‐associated metabolites profiles using a nontargeted liquid chromatography‐mass spectrometry (LC‐MS/MS)‐based method. Beef longissimus dorsi samples were purchased immediately after slaughter, and then stored at room temperature, 4 °C and 0 °C. Water holding capacity (WHC), moisture content and pH value of the muscle samples were detected. Muscle samples and quality control samples were then prepared for nontargeted LC‐MS/MS system, followed by identification of distinct metabolites. Pearson correlation coefficients between metabolites and quality indexes were calculated. Storage reduced pH values of beef, and room temperature and 4 °C displayed the lowest pH value. Moisture content and WHC in beef muscles, especially WHC declined obviously during the first 24 hr. The significantly altered metabolites profiles in meat samples at 0, 3.5, and 7 days during 4 °C storage were identified using LC‐MS/MS. Most metabolites showed linear changes during storage (0 to 7 days). Using Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, we found 1(α)‐naphthol, urocanic acid, tyramine, guanine, histamine, picolinic acid, 4‐hydroxybenzaldehyde, and hypoxanthine were increased, and 2‐(S‐glutathionyl)acetyl glutathione and glutathione were decreased in beef during 4 °C storage. Correlation analysis showed there were significantly correlations between metabolites and meat quality indexes (WHC, moisture content, and pH). In summary, 1(α)‐naphthol, urocanic acid, tyramine, guanine, histamine, picolinic acid, 4‐hydroxybenzaldehyde, and hypoxanthine, proved to be harmful to human body, accumulated gradually, especially after 3.5 days during storage at 4 °C. While the contents of beneficial substances, including 2‐(S‐glutathionyl)acetyl glutathione and glutathione, were decreased, which provided reference for the nutrition guidance of using beef meat.
The interactions between black soybean protein isolate (B‐SPI) and cyanidin 3‐O‐glucoside (C3G), anthocyanin extracted from black soybean coat was investigated under neutral conditions. The fluorescence spectra showed that C3G had fluorescence quenching effects on B‐SPI. Thermodynamic parameters showed that ∆ G < 0, which demonstrated that the binding was a spontaneous reaction. Since ΔH > 0 and ΔS > 0, the interactions between C3G and B‐SPI was mainly hydrophobic interactions. Fourier infrared spectroscopy results suggested that the contents of α‐helix and β‐sheet structure showed an increasing trend, whereas the β‐angle content displayed a decreasing trend. The degradation of C3G followed first‐order kinetics at 85 °C and 100 °C. After the interactions with B‐SPI, the degradation rate constant was decreased and the half‐life of C3G was prolonged from 70.25 ± 0.90 min to 175.64 ± 38.04 min at 85 °C, from 62.68 ± 1.1 min to 72.51 ± 2.5 min at 100 °C (p < 0.05). The results indicated that the interactions of B‐SPI and C3G improved the thermal stability of C3G under heating conditions.
