Through response surface methodology, the optimal conditions were obtained as follows based on microencapsulation efficiency: the ratio of bacteria/EHSPI 1:1.83, EHSPI content 4.01%, modified phospholipid content 11.41%. The results of digestion in vitro showed that after passing through the simulated gastric fluid (SGF), the L. plantarum was released and reached 3.55 × 108 CFU/mL in the simulated intestinal fluid. Meanwhile, the surviving bacteria number of control significantly decreased to 2.63 × 104 CFU/mL (P < 0.05) at 120 min in SGF. In sum, the acid resistance and survival of L. plantarum were improved in SGF in vitro, through the microencapsulation technology based on EHSPI.","PeriodicalId":13976,"journal":{"name":"International Journal of Food Engineering","volume":"18 1","pages":"499 - 511"},"PeriodicalIF":1.6,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47050721","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}

Procedure exhibiting higher heating rate and lower thermal non-homogeneity was set as the deciding factor for an optimal heating scheme. In order to achieve optimal processing at both 915 and 2450 MHz frequency, rotation of smaller samples and non-rotation of larger samples were recommended in most of the case studies; however, few exceptions were also observed and reported. In addition, reciprocity between volume fraction, intensity of the microwave radiation and procedure duration was also discussed.

Fortification of a wheat flour-based staple food such as dried noodles, with corn silk flour could directly affect the pasting properties of wheat flour and hydration properties of dough, and thus influence the quality of dried noodles. The competition for water between corn silk flour and wheat flour inhibited the gelatinization of starch and hindered the formation of the gluten network which harmed the cooking properties and decreased consumer acceptance of the resulting dried noodles. Nutritionally, the dietary fiber and polyphenols content of the resulting dried noodles was effectively improved, especially at a 6∼9% replacement rate. The current work demonstrates the feasibility of fabricating corn silk flour-enriched dried noodles and its nutritional superiority compared to the corresponding normal product.","PeriodicalId":13976,"journal":{"name":"International Journal of Food Engineering","volume":"18 1","pages":"479 - 487"},"PeriodicalIF":1.6,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48260830","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}

The intermolecular interaction between host and guest was studied by 2D-ROESY NMR and the inclusion mode was proposed. Finally, the heat-controlled release experiment indicated that the inclusion complexes of ACBs/EVA possess less volatilization at higher temperature, longer retention time and heat-controlled release.

A novel computer simulation to model momentum, heat, and mass transfer was developed to investigate the effect of SOR (1/10, 1/15, and 1/20) on velocity, temperature, moisture, and oil distributions during frying of potato strips. The present study was intended to cover missing aspects in scientific literature dealing with potato frying modeling. In addition, one of the major contributions offered by this work regarded the possibility of major effect of SOR on healthiness of products. An increase in water vapor production at a higher SOR played a significant role in increasing oil velocity. While the SOR did not have a substantial effect on center temperature of potato strips, surface temperature decreased with an increase in SOR. The SOR affected moisture content of the corners of the specimens, whereas it did not significantly affect the center moisture. Simulation of the longitudinal section of potato center showed that oil uptake increased with increasing SOR. The decrease in oil uptake by decreasing SOR was justified by the water vapor production and crust formation. Water vapor acted as a barrier against oil diffusion and had a significant impact on stirring the oil and creating homogeneous temperatures. Overall, this study offered a proper numerical tool to control oil absorption, leading to understanding complex mechanisms during deep-fat frying of foods. It is hoped that the results of this study could head to a further step in developing an optimized deep-fat frying process.","PeriodicalId":13976,"journal":{"name":"International Journal of Food Engineering","volume":"18 1","pages":"337 - 358"},"PeriodicalIF":1.6,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43415756","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}
