Abstract
This article presents the results of a comprehensive toxicity assessment of brazzein and monellin, yeast-produced recombinant sweet-tasting proteins. Excessive sugar consumption is one of the leading dietary and nutritional problems in the world, resulting in health complications such as obesity, high blood pressure, and cardiovascular disease. Although artificial small-molecule sweeteners widely replace sugar in food, their safety and long-term health effects remain debatable. Many sweet-tasting proteins, including thaumatin, miraculin, pentadin, curculin, mabinlin, brazzein, and monellin have been found in tropical plants. These proteins, such as brazzein and monellin, are thousands-fold sweeter than sucrose. Multiple reports have presented preparations of recombinant sweet-tasting proteins. A thorough and comprehensive assessment of their toxicity and safety is necessary to introduce and apply sweet-tasting proteins in the food industry. We experimentally assessed acute, subchronic, and chronic toxicity effects, as well as allergenic and mutagenic properties of recombinant brazzein and monellin. Our study was performed on three mammalian species (mice, rats, and guinea pigs). Assessment of animals' physiological, biochemical, hematological, morphological, and behavioral indices allows us to assert that monellin and brazzein are safe and nontoxic for the mammalian organism, which opens vast opportunities for their application in the food industry as sugar alternatives.

Abstract
The acute oral, cutaneous, and inhalation toxicity of aversectin C was studied on white unbred rats and mice. The compound was less toxic for rats than for mice, the LD50 for oral administration being 90 and 33 mg/kg, respectively. Aversectin C exhibited a maximum acute toxicity upon the inhalation in rats (LD50 = 40 mg/kg), while a minimum toxicity level was observed for the cutaneous application in rats (1700 mg/kg).

Abstract
Aversectin C was evaluated for mutagenic activity in the Ames test with Salmonella typhimurium TA 97, TA 98 and TA 100, in the dominant lethal assay on uninbred albino rats in a dose of 2.25 mg/kg body weight (1/40 of the LD50) and in the metaphase test on F1CBAxC57BI/6 mice in a dose of 8.2 mg/kg body weight (1/5 of the LD50). The agent showed no mutagenic activity in any of the tests. The anaphase test on F1CBAxC57BI/6 mice revealed no antimitotic activity of aversectin C.
