    Biomimetic foods are expected to have potential health benefits for the management and prevention of chronic diseases, such as diabetes and cardiovascular disease. In the current research, two commercially available and affordable plant proteins (soy protein isolate-SPI and pea protein isolate-PPI) at two levels (5%, 10%) were added to the Yangyu jiaotuan with the objective of developing a product with reduced glycaemic properties and high protein content while maintaining its original taste and texture. The results showed that several important textural properties such as hardness and chewiness did not change significantly during the refrigerated storage. The storage modulus G' increased with refrigerated storage time for different samples, but there were significant differences among the five samples (with and without protein addition) with respect to frequency dependence during rheological measurements. The in vitro starch digestion experiments showed that the starch hydrolysis of Yangyu jiaotuan decreased considerably (by up to 42.08%) with the increase in PPI content and during refrigerated storage due to starch retrogradation. Protein has protected the microstructure and there was less damage when compared to samples without protein. The bimodal peaks of the particle size distribution curves showed that the newly developed Yangyu jiaotuan contains two different sizes of particles; the smaller particles (~30 μm) corresponded to PPI and starch granules, while the larger particles corresponded to the fragments of the gel network of the starch matrix. Based on the above results, Yangyu jiaotuan mixed with pea protein is a convenient potato staple food product, which complies with the biomimetic potato food very well.

    Rice Germination and Its Impact on Technological and Nutritional Properties: A Review
    (Elsevier BV on behalf of the China National Rice Research Institute, 2022-05-06) do Nascimento LÁ; Abhilasha A; Singh J; Elias MC; Colussi R
    Grain germination is a process involving numerous factors that influence the biochemical processes inside the plant cells. This review covered the abiotic factors that lead to the germination and significantly impact the nutritional properties and digestion behavior of rice grains. The macro- and micro-nutrients can be changed depending on the intensity of the applied variables during germination. For instance, germination time can increase the protein content in the grain and concurrently reduce its protein digestibility. In most cases, the number of bioactive compounds present in rice grains are increased regardless of germination conditions. Germination can promote the complexation of nutrients and thus negatively interfere with the digestibility of macronutrients. This review highlighted the influence of the germination process on the nutritional quality of rice grains, providing information about the germination conditions and their impacts on the anabolic and catabolic reactions of the grain, emphasizing the health benefits.
