This paper reviews the entire process of salted egg production, including salting, post-curing, cooking, and preservation, to fully explore the mechanisms of quality formation. The application of rapid processing, such as physical treatment and chemical additives, to reduce the salt content of SEW and enhance the quality of SEY is elaborated. Besides, the preference for SEY flavor leads to a great waste of SEW with high salt content lacking in foaming ability and low viscosity. Therefore, value-added SEY application as functional ingredients and converting the wastage of higher salt content SEW into valuable products are discussed in this paper. It will provide valuable information to improve processing efficiency, enhance the quality of salted eggs and promote the development of high-value-added and environmentally friendly nutritional egg products.</p>","PeriodicalId":101198,"journal":{"name":"Sustainable Food Technology","volume":" 5","pages":" 1409-1427"},"PeriodicalIF":0.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/fb/d4fb00129j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142246637","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}

It is dense in several valuable nutritional components such as carbohydrates, dietary fiber, minerals and some bioactive substances but low in protein. One of the strategies to facilitate its valorization is suggested as enhancing its protein content. Therefore, solid-state fermentation (SSF) of carob pulp was investigated using the edible fungus species <em>Pleurotus ostreatus</em>. For this purpose, carob pulp was first soaked with water, then treated thermally at 121 °C and subsequently subjected to SSF. During the SSF period of 30 days, samples were drawn every 5 days and analyzed with respect to protein, reducing sugars (glucose and fructose) and dietary fiber contents as well as polyphenol content and antioxidative properties. SSF with <em>Pleurotus ostreatus</em> could be proven to triple the protein content as well as the total fiber content of carob pulp. An increase in protein content is likely connected to the production of fungal biomass. However, a decrease in the reduced sugar content as well as in the antioxidant properties was observed.

This paper explores the potential of alginate-based food packaging as an environmentally friendly method for food-related issues. Alginate, a naturally occurring polysaccharide extracted from seaweed, has considerable potential as a sustainable packaging material due to its multifaceted properties. These properties enable alginate to encapsulate and preserve a wide range of food products effectively. Alginate food packaging has demonstrated its ability to prolong the shelf life of various food products, including fresh fruits, vegetables, meats, and baked goods. It is beneficial to maintain their moisture content and maintain oxygen levels. Furthermore, it is an effective barrier against microbial growth, while preserving the desired flavor and aroma profiles of the packaged items. Antimicrobial food packaging systems are specifically designed to inhibit microbial growth on surfaces, thus enhancing overall stability and preserving quality during storage periods. However, additional research is necessary to improve performance across various applications within the food industry. Alginate-based edible coatings have attracted significant attention due to their ability to enhance both sensory attributes, such as appearance, and mechanical properties across diverse categories including fruits, vegetables, meat, poultry, seafood, and cheese.
