The aim of this research was to develop and solve the experimental mathematical model which described the cold-drying process to produce pennywort powder product. Results obtained were to build the multi-objective optimization for cold-drying process of pennywort and the product after drying was good quality, the moisture content was met requirement and the energy cost reached lowest level. The technological mode of cold-drying process for pennywort was found out by solving multi-objective optimization as follow: the optimal drying temperature was 44.24⁰C, the optimal drying time was 14.12hours and the optimal drying velocity was 12.83m/s. Corresponding to these optimal factors, the solute concentration reached the minimum value of 11.31%; moisture content reached the minimum value of 3.65%; ΔE of 2.056 while the energy consumption for 1kg final product reached the minimum value of 1.1 kWh / kg.

In this article, the immunomodulatory, antioxidantive, anti-microbial, anti-inflammatory, anti-hypertensive, anti-diabetic, anti-cancer, mineral-binding and cholesterol-lowering effects and opioid activities of physiologically active or bioactive peptides are discussed. Specific and small protein particles that have a positive impact on human metabolism or body conditions are called bioactive peptides. Bioactive peptides primarily affect gastrointestinal system, nervous system, cardiovascular system and immune system. These peptides are very important for pharmaceuticals and functional food formulations because of their beneficial properties for human health. Empiric and bioinformatics studies have provided important informations and nowadays, thousands of bioactive peptides identified.

In recent years, nanotechnological improvements are promising for the future. Nanoscience and nanotechnology have various applications and improvements notably for computer, electronic, textile and drug industry. Moreover, of high importance are the applications of these technologies for the agricultural and food engineering areas. Actually, the most important point, in the improvement of nanotechnology is the multidisciplinary study of all these sciences. The improvement of nanotechnology in the food industry is slower owing to the fact that foods are complex materials. Despite this fact, this technology has important area of uses in the food industry. Using of nanomaterials and nanodevices important improvements were recorded. Among the food chain, nanotechnology has a bright role in four major areas. These areas, where nanotechnology can be present and important are: food processing at nano- and microscale; developing of novel functional food materials; transport of bioactive materials and their smart release system and improving shelf life by developing new food packaging products. So, at this point, engineering applications and developing these applications are very important for nanotechnology. However, it should be remembered that nanoparticles created with nanotechnology applications, which have opened a whole new universe in the food industry, can form toxic compounds so human health can be adversely affected.

Multiple Traffic Light (MTL) could alert excess of saturated fat, sugar or sodium in food products. The aim of this research was to study the saturated fat, sugar and sodium contents informed in the principal biscuit labels commercialized in Brazil, as well to understand some biscuit consumer habits of Brazilian people, and finally, to propose new labels according to the MTL model for biscuits with excess of saturated fat, sugar or sodium. The saturated fat, sugar and sodium contents of the principal biscuits commercialized in Brazil was studied. Also, a cross-sectional study with 100 interviewees aged between 18 and 60 years old was conducted. One hundred percent of biscuit labels studied have high or medium contents of saturated fat, sugar or sodium. A high frequency of biscuit consumption by interviewees without and with non-communicable diseases was observed. Also, it was observed that Brazilian interviewees are not understanding the information contained in biscuit labels. It is possible to suggest the necessity of more studies, as well as the implementation of MTL model in biscuit labels commercialized in Brazil.
