“…Interestingly, cellulose and chitin are the first and the second most abundant natural polysaccharides on earth. The chemical structure of cellulose consists of a linear structure of β-1,4-linked D-glucose residues, while chitin is composed of β-1,4-linked units of the amino sugar N-acetyl-glucosamine [196][197][198]. CMC and CMCH are both broadly used in the food industry, including their use as coating material in the microencapsulation of probiotics.…”

The consumption of probiotics has been associated with a wide range of health benefits for consumers. Products containing probiotics need to have effective delivery of the microorganisms for their consumption to translate into benefits to the consumer. In the last few years, the microencapsulation of probiotic microorganisms has gained interest as a method to improve the delivery of probiotics in the host as well as extending the shelf life of probiotic-containing products. The microencapsulation of probiotics presents several aspects to be considered, such as the type of probiotic microorganisms, the methods of encapsulation, and the coating materials. The aim of this review is to present an updated overview of the most recent and common coating materials used for the microencapsulation of probiotics, as well as the involved techniques and the results of research studies, providing a useful knowledge basis to identify challenges, opportunities, and future trends around coating materials involved in the probiotic microencapsulation.

“…Metabolites associated with fecal DNA may have survived passage through the upper gut, and are more representative of the nutrient environment in the colon, which is particularly relevant to the metabolic activity of our commensal microbiota. MEDI may also provide insight into the consumption of certain highly-processed foods, due to the presence of DNA that is likely derived from common non-caloric bulking agents added to these foods, like cotton-derived cellulose and pine wood pulp 50,51 . Specifically, hibiscus (cotton plants are closely related to hibiscus) and pine tree DNA were among the most prevalent food components identified in MEDI-inferred diets from the METACARDIS cohort.…”

Dietary intake is tightly coupled to gut microbiota composition, human metabolism, and to the incidence of virtually all major chronic diseases. Dietary and nutrient intake are usually quantified using dietary questionnaires, which tend to focus on broad food categories, suffer from self-reporting biases, and require strong compliance from study participants. Here, we present MEDI (Metagenomic Estimation of Dietary Intake): a method for quantifying dietary intake using food-derived DNA in stool metagenomes. We show that food items can be accurately detected in metagenomic shotgun sequencing data, even when present at low abundances (>10 reads). Furthermore, we show how dietary intake, in terms of DNA abundance from specific organisms, can be converted into a detailed metabolic representation of nutrient intake. MEDI could identify the onset of solid food consumption in infants and it accurately predicted food questionnaire responses in an adult population. Additionally, we were able to identify specific dietary features associated with metabolic syndrome in a large clinical cohort, providing a proof-of-concept for detailed quantification of individual-specific dietary patterns without the need for questionnaires.

“…A high DS can significantly weaken the hydrogen bonding to give cellulose good water solubility and even solubility in polar organic solvents. 45 Interestingly, some cellulose derivatives are temperature sensitive. For example, HPC aqueous solutions exhibit an unusual solubility behavior with good solubility in cold water, but insolubility in hot water, resulting in the gelation of cellulose chains.…”
