Minimum and maximum hardness levels were 13.32 kg and 22.64 kg, as determined in the control sample and the chips enriched with 8 g/100 g PPF, respectively. Total phenolic of the chips was in the range of 364.7–1107.2 mgGAE/kg and increased significantly (P < 0.05) with increasing of the PPF. In addition, total dietary fiber content of the samples also increased (by 20%) significantly (P < 0.05) by PPF incorporation while the in vitro glycemic index content of samples decreased (P < 0.05).

The results showed that 2.26% samples were positive for Cronobacter among the 33 isolates that were identified. All Cronobacter isolates were susceptible to 12 antimicrobial agents tested except one isolate which showed intermediate resistance to Chloramphenicol. PFGE analysis showed that nine clusters comprising the 33 isolates were identified, among which C8, C4, and C5 were the predominant types. All 33 isolates were capable of forming biofilm, and particularly, C. malonaticus isolates showed a good biofilm-forming ability at both 28°C and 37°C.

Frozen minced beef products with 10 and 15% of fat content were kept at ?5, ?15, and ?23°C, and over a 6-month period, they were assessed for moisture content (MC), peroxide values (POV), acid values (AV), 2-thiobarbituric acid (TBA) value, total volatile basic nitrogen content (TVB-N), and the sensory test in order to identify the effect on quality. This helped to determine their appropriate storage duration at a given temperature. Multiple regression analysis was used to assess the correlations between storage tempera-ture, fat meat percentage, characteristic factors, and overall acceptance (OA). Five months for ?23°C, 4 months for ?15°C, and 2 months for ?5°C met 3.7 points or more of OA, in accordance with global sensory analysis stan-dards, and were determined as acceptable frozen storage durations. The very high multiple regression analysis R2 (0.97–0.99) verified the correlation between the characteristic factors and OA. In addition, TVB-N, MC, and POV, respectively, were the main quality factors affecting OA at ?5, ?15, and ?23°C (R2 > 0.8).

Results showed that all experiments have shorter drying time and higher essen-tial oil content than the shade-drying method. Also, the best drying conditions that led to an optimal essential oil yield (1.73 mL/g DM) involved a lower temperature (30°C) and velocity (2 m/s) and a mesh size of 10 mm.

In this study, Lactobacillus acidophilus was exposed to stress with B. persicum essential oil (BEO), NaCl, bile salts, and their combinations by 50 minimum inhibitory concentration (MIC) and then inoculated to the yogurt samples, which were stored at 4°C for 28 days. Indepen-dent parameters in this article are BEO 500 and 1000 ppm that the physicochemical, sensory properties, and L. acidophilus of viability in yogurt samples were assessed within the time. A steady increase in syneresis percent-age and acidity was observed, while pH values were reduced in all samples. The L. acidophilus survival decreased during storage time in all treatments. In addition, sensory scores showed a reduction trend in the samples. The survival rate of probiotic bacteria is also impacted by redox potential. Increasing the oxidation and resuscitation potential and increasing the hydrogen peroxide concentration due to the bacteria metabolic activity are among the factors that reduce the probiotic bacteria population in yogurt during storage. The most viability of L. acidophilus under stress with BEO compared with other stress treatments may be due to slight changes in pH during this period than in the stress treatments. Generally, it can be argued that the usage of BEO, NaCl, and bile salts at a MIC of 50% in yogurt stored in the refrigerator for 21 days provided a suitable environment for the storage and transmission of L. acidophilus, as recommended to the consumer and, therefore, the current results confirmed that the addition of probiotic and these materials improved the physicochemical and sensory characteristics of yogurt.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":"13 1","pages":"37-48"},"PeriodicalIF":4.0,"publicationDate":"2021-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45210276","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}

Recently, scientists recognized that human wellness and healthy life are going to face challenges in the near future because of the vulnerability of agriculture and nat-ural resources. It is due to imbalance and unnecessary use of synthetic agricultural inputs in traditional farming systems. Therefore, improved agricultural technology has to ensure, in traditional farming, safe agricultural produce and bringing down of environmental pollution. Recently, nanotechnology (NT) has been recognized as a promising next-generation technology in the field of agriculture. As an environment-friendly and economically viable tool, the potentiality of nanomaterials (NMs), such as nanosensors, nanopesticides, nanofertilizers, nanocarriers, nanochips, and nano-packaging, has shown great prospect in improving safe agricultural productivity and upholding of environmental safety. Because the use of NMs decreases imbalance and unconscious utilization of synthetic fertilizers and pesticides, this minimizes the loss of nutrients and lead to improved agricultural productivity thru the smooth distribution of fertilizers and pesticides, and also improving water and nutrient effi-ciency.

Nevertheless, the few remaining Datura seeds (up to one nut per 30 kg) could lead to an exceedance of the European Union (EU) limit values for tropane alkaloids in baby food. However, plant material other than seeds or even invisible abrasion of Datura seeds can contaminate the millet during harvest, handling, cleaning processes or crop transportation.
