Microencapsulation with spray-chilling as an innovative strategy for probiotic low sodium requeijao cremoso processed cheese processing

The effect of sodium reduction and Lactobacillus acidophilus addition(free or microencapsulated)on the quality parameters of requeijao cremoso processed cheese was assessed for 90 days at 5℃.Three formulations were prepared:(CONT)regular salt content and curd fusion(90℃/2 min),(FREE)reduced salt content+free probiotic culture added after curd fusion(90℃/2 min),and(MICRO)reduced salt content+microencapsulated probiotic culture added before curd fusion(70℃/5 min).FREE and MICRO formulations showed increased monounsaturated and polyunsaturated fatty acid content,improved health indices(decreases in thrombogenic index and increases in desirable fatty acid index),and altered rheological properties(higher consistency index,apparent viscosity,elastic properties,and gel strength).In addition,the MICRO formulation showed higher texture sensory acceptance and probiotic counts higher than 6 log CFU/g during storage and simulated gastrointestinal conditions.Overall,microencapsulation of probiotics with spray chilling represents an innovative solution in requeijao cremoso processed cheese.

Prebiotics in non-dairy products:Technological and physiological functionality,challenges,and perspectives

Vegan consumers look for fresh,tasty,and nutritious products that use eco/animal-friendly ingredients.Prebiotics are substrates selectively utilized by host microorganisms conferring a health benefit.This study aimed to overview the potentially vegan products added with prebiotics,their health benefits,and the main technological and sensory challenges.The main potentially vegan products added with prebiotics studied were based on water-soluble plant-based extracts(fermented beverages,frozen desserts,cheese analog),fruits(fruit juices,fruit jelly,and ready to eat fruits),and cereals(snack bars,granola bars,bread,and cookies).The main prebiotic compounds used were inulin,fructooligosaccharides,oligofructose,polydextrose,and xylooligosaccharides.The effects of prebiotic on food products’,host health,and technological and sensory properties depended on the prebiotic type and dosage,food matrix,and subject type.The positive health effects were related to skin health,gut microbiota improvement,hypocholesterolemic impact,reduction of the risk of metabolic diseases,and improvements in postprandial blood glucose and insulin response.Prebiotics could improve vegan products’technological and sensory properties,such as fermentation time,texture and rheological properties,storage length,sensory acceptance,and probiotic survival.Furthermore,they could increase the concentration and/or bioaccessibility of phenolic compounds and vitamins.However,it is of paramount importance the determination of prebiotic stability.The trends direct to new prebiotic compounds based on microalgae,fruit and cereal by-products,and seeds.This review provides industries and researchers with important information about prebiotics and vegan products.
