Decreasing consumption trends have forced companies to look for healthier choices for their products. C-phycocyanin CPC, a bright blue cyanobacterial pigment with anti-oxidant and other health benefits has been proposed as a candidate in edible drinks. We found that CPC is stable in a wide pH and temperature regime. Reaction kinetics for 12 weeks at 4 °C in non-alcoholic carbonated beverages (B1-B4) showed that B3 (sweetened, ~30 % degradation) best preserved CPC integrity while B1 (non-sweetened, ~87 % degradation) was ineffective. Other beverages (sweetened) could preserve ~ 49 % CPC integrity. Behnajady-Modirshahla-Ghanbary and first order kinetic models explained CPC degradation with and without preservative (sucrose), respectively. The ’consume-by’ times suggest possible refrigeration from ~ 13 hours to 27 days for various CPC-containing beverages. Results suggest CPC could be filter-sterilized and added to non-alcoholic beverages before being packaged in cans or tetra packs to avoid light exposure.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":15086,"journal":{"name":"Journal of Applied Phycology","volume":"8 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140559922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario the use of natural sources such as <em>Ascophyllum nodosum</em> extracts (ANE) which contribute to the better adaptation of plants to environmental stresses, gains relevance. Nonetheless, understanding the metabolic effect of ANE according to the time of application could be better explored, such as, if the application before or during the stress occurrence can trigger different metabolic responses. Thus, this work aimed to identify the physiological and biochemical effects of foliar application of ANE at different times, in soybean plants subjected to water restriction. The experiment was carried out in pots with plants at the vegetative stage, subjected to foliar sprays of ANE in the following treatments: (i) application of ANE at adequate humidity with 80% of the substrate water holding capacity (WHC); (ii) application of ANE three days before the humidity reached 50% of the substrate WHC; (iii) application of ANE on the day that WHC reached 50% (established as drought stress condition); (iv) positive control without application of ANE and WHC 50%; (v) absolute control, without application of ANE and without water restriction. The results allow to point out that ANE application three days before drought stress improved nitrate reductase enzyme activity, chlorophyll and proline content, decrease lipid peroxidation and presented more effective improvement of peroxidase enzyme activity; while application at stress condition resulting in more effective reduction of stomata resistance, long term expressive proline content increment, more effective improvement of superoxide dismutase and catalase enzymes activity and reduce chlorophyll degradation.
