Macronutrients of pulses or cereals are stored in the cotyledon or endosperm cells with protection from intact cell walls. However, pulses and cereals are generally processed into fine particles during food production. For example, after milling, the macronutrients enclosed in the intact cells are released and are easily accessible to digestive enzymes in the gastrointestinal tract, leading to high metabolic responses. Therefore, studies on the health effects of intact cells and developing an alternative ingredient with a higher proportion of intact cells are areas of emerging interest. In this review, we highlighted the smallest unit of whole grain, an individual cell, as "nutritional capsules" and elucidated the structure–function of the nutritional capsules, followed by isolation techniques, as a potential novel functional ingredient and food. The polysaccharides’ monomeric composition, secondary structure, and interactions determine the cell wall properties including the cell detachment during isolation and isolated cell properties. The intact cellular structure is retained after mild food processing and digestion, thereby, contributing to a lower extent/rate of digestion of entrapped macronutrients. Furthermore, the excursed intact capsules in the colonic environment modulate the population and diversity of microbiota, favouring the increased production of the short‐chain fatty acids (SCFAs). The structural schematic model of Type‐I and Type‐II cells is developed together with the schematics of the cell wall isolation process. The review provides a critical summary of the recent trends in intact plant cells as a functional‐nutritional food. It paves the way for the industrial production of intact cells as a novel food ingredient.

Fish is perishable and has the short shelf‐life. To maintain its quality, it is necessary to implement the appropriate technology, particularly nonthermal processing along with safe additive, especially from plant origin under the concept of "hurdle technology". The use of potential vesicle including liposome for loading the plant extract could be a means to enhance the stability and activities of the extract. The current study aimed to evaluate the effect of liposomes loaded with betel leaf ethanolic extract (L/BLEEs) or unencapsulated BLEE (U/BLEE) in conjunction with modified atmospheric packaging (MAP) and nonthermal plasma (NTP) on the quality changes and shelf‐life of Nile tilapia fillets (TFs) stored under refrigerated condition (4°C). TFs treated with L/BLEE or U/BLEE at 400 ppm, packed under modified atmosphere (CO2:Ar:O2 = 60:30:10) and subjected to NTP for 300 s (L/BLEE‐400/MAP‐NTP and U/BLEE‐400/MAP‐NTP, respectively) had the lowest microbial and chemical changes during storage, while the control showed the highest changes (p < 0.05). Lipid oxidation was lower in these samples, ascertained by more retained polyunsaturated fatty acids and lower lipid oxidation based on Fourier transform infrared (FT‐IR) spectra. Overall likeness scores were similar (p > 0.05) between all the samples at day 0 of storage. Only L/BLEE‐400/MAP‐NTP and U/BLEE‐400/MAP‐NTP were still sensorially acceptable after 12 days at 4°C. Therefore, L/BLEE or U/BLEE combined with MAP/NTP treatment could be adopted as a potent hurdle for shelf‐life extension of TFs. Practical Application Natural additives and nonthermal processing technologies have gained increasing interest for preservation of fish. Liposomes loaded with betel leaf ethanolic extract (L/BLEE) rich in polyphenolics could be used together with modified atmospheric packaging (MAP) and nonthermal plasma (NTP) to retard bacterial growth and chemical deterioration in Nile tilapia fillets. These hurdles were proven to be able to maintain the qualities of tilapia fillets stored at 4°C up to 12 days, especially when L/BLEE was used at 400 ppm. Therefore, shelf‐life extension of Nile tilapia fillets or other fish can be achieved by using the natural additive and nonthermal processing technologies.

Scope Human milk oligosaccharides (HMOs), multifunctional glycans naturally present in human milk, are known to contribute to the infant's microbiota and immune system development. However, the molecular specificity of HMOs on microbiota and associated fermentation is not yet fully understood, and is important for the development of infant formula optimum functionality. Methods and results In vitro fermentation is carried out on structurally different HMOs with infant fecal inocula dominated by Bifidobacterium longum, Bifidobacterium breve, and Bacteroides. The gas, metabolite (SCFA, lactate, and succinate) profiles, and microbiota responses differ between individual microbiota inocula patterns regardless of HMO structure. In terms of HMO pairs with same sugar composition but different glycosidic bonds, gas and metabolite profiles are similar with the B. longum‐ and B. breve‐dominated inocula. However, large individual variations are observed with the Bacteroides‐dominated inocula. The microbial communities at the end of fermentation are closely related to the initial microbiota composition. Conclusion The findings demonstrate that short‐term in vitro fermentation outcomes largely depend on the initial gut microbiota composition more than the impact of HMO molecular specificity. These results advance the current understanding for the design of personalized infant nutritional solutions and therapies in future.
