To ensure this in Germany, a school food standard (SFS) was established. Implementation of the SFS is mandatory only in some federal states and has remained voluntary in others. The aim of this first exploratory study is to analyze school lunch menus regarding their fulfillment of the SFS requirements and detect differences between obligatory and voluntary implementation of the SFS.</div></div><div><h3>Methods</h3><div>After drawing a random sample of schools and reaching out for voluntary participation in this study, school menus of federal states with obligatory (OSFS) and voluntary (VSFS) SFS implementation were collected and analyzed. The SFS criteria are based on the conditions observed in the menu for a four-week mixed diet menu, an ovo-lacto-vegetarian dish, additional criteria for menu planning and menu criteria. In addition, we estimated binominal logistic regression models and two-step multiple regression models to control for the effects of geographical factors and socioeconomic status to the fulfillment of the SFS criteria.</div></div><div><h3>Results</h3><div>We assessed 48 menus from OSFS federal states and 102 menus from VSFS federal states. OFSF menus met the requirements to a higher extent and exhibited a better dietary pattern. School food-standardized meals included significantly less breaded and deep-fried components (96 % vs. 79 %, <em>p</em> = 0.009), contained more whole grain products (83 % vs. 30 %, <em>p</em> &lt; 0.001) and fewer meat products (60 % vs. 25 %, <em>p</em> &lt; 0.001), more fruits (81 % vs. 63 %, <em>p</em> = 0.023) and more vegetables, legumes and salad (85 % vs. 61 %, <em>p</em> = 0.002). Menus with SFS obligation emphasized nutrient optimized menus significantly more frequently (42 % vs. 28 %, <em>p</em> &lt; 0.001) and used unambiguous designations of meals more often (96 % vs. 82 %, <em>p</em> = 0.023).

The powdered tea market is expanding in popularity due to its functional properties. This study aimed to examine the influence of different particle sizes of mulberry leaf powder (MLP) infusion on the digestibility of starch in cooked <em>Japonica</em> rice (cv. Koshihikari) and the bioaccessibility of phytochemicals. Dried mulberry leaf was pulverized and sieved into several particle sizes: 160 μm (MLP160), 250 μm (MLP250), 404 μm (MLP404), and 774 μm (MLP774). Through simulated <em>in vitro</em> digestion, we assessed starch hydrolysis (%S_H), the kinetics of starch hydrolysis, estimated glycemic index (eGI), as well as total phenolic content (TPC) and total flavonoid content (TFC). The smaller particle size of MLP showed a greater reduction of eGI. Specifically, infusions prepared from MLP160 resulted in a reduction of 15 % in eGI for cooked grains and 3 % for slurries, respectively. The reduction in eGI was attributed to the interaction among flavonoids and digestive enzymes, demonstrating a concentration-dependent manner on enzyme inhibition effect. Pulverization significantly influenced the concentration of phytochemicals and their bioaccessibility in infusions. This study offers valuable insights into determining optimal particle sizes for MLP, considering both physical and functional characteristics as well as implications for the food industry. The results further suggest that MLP infusion holds promise as a functional beverage, potentially providing benefits in reducing postprandial hyperglycemia.</div></div>","PeriodicalId":19294,"journal":{"name":"NFS Journal","volume":"37 ","pages":"Article 100196"},"PeriodicalIF":4.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increasing demand for CM among people with lactose intolerance is expected to positively impact the industry. Despite efforts to develop a range of products from CM, its processing is generally considered challenging, and the resulting products are not comparable to those made from bovine milk. For decades, the dairy industry has relied primarily on conventional methods to process various dairy products; however, these methods can affect the organoleptic quality and nutritional profiles. This review focuses on innovative non-thermal processing methods for CM, including high-pressure processing, pulsed electric fields, ultrasonication, UV pasteurization, cold plasma technology, and microwave processing.
