The study of the quality of butter with flavoring components

The paper proposes to improve the quality of butter with flavoring components during storage through the use of prescription ingredients containing natural antioxidants. The composition of the flavor component includes: tomato flakes; salt; olives, basil, onions, oregano, garlic, sugar, sage. According to the results of the scoring of the samples, the optimal dose of adding a flavoring component of 1.0% was established. Taking into account the recommended standards according to GOST 32899, the salt in the composition of the flavor component contains an insufficient amount, so it was added to the oil in addition to a total content of 1% in the product. In tomato flakes, which make up more than half of the entire mixture of the flavoring component, a high content of beta-carotene, vitamin C, PP, B1, B2, B6 is noted. Also, a high content of vitamin E in olives, basil, oregano; vitamin C - in sage; vitamin PP - in basil, oregano, sage; Vitamin B1 - in oregano, garlic, sage, Vitamin B2 - in basil, oregano and sage, B6 - in basil, onion, oregano, garlic, sage. Amperometric method found an indicator of the antioxidant activity of the taste component of 0.382 mg / g The resistance of fat oil with flavoring components was determined. The sample passed the test for 8 hours, no spoilage of fat was noted. Microscopic studies of oil samples were carried out using a Altami BIO digital microscope at a magnification of 200 times. The microstructure of butter with flavoring components is characterized as granular, plasma drops are evenly distributed in the sample. Some consistency indicators are identified. A good cut-through consistency was established and good heat resistance of the oil with taste components. Organoleptic characteristics of butter with flavoring components: taste and smell creamy, salty, piquant, aroma and taste of the introduced component; plastic consistency with inclusions of the added component, glossy surface; color light cream with grains of the introduced component. The main physicochemical parameters of butter with flavoring components were established experimentally: mass fraction of fat 62.0%; mass fraction of moisture 32.5%; salt - 1%. Microbiological indicators comply with regulatory requirements. The addition of a flavoring component to butter contributes to the formation of its dense structure, stable storage of the fat fraction, and uniform distribution of the oil plasma. The product has improved quality indicators.

Influence of Ethyl Caproate on the Size of Lipid Vesicles and Yeast Cells

Ethyl caproate (EC) is a key flavor component of sake. Recently, in sake brewing, an effort has been underway to increase the content of aromatic components such as EC. However, the function of EC in yeast cells remains poorly understood. Therefore, we investigated the effects of EC using cell-sized lipid vesicles. We found that vesicle size decreases in a concentration-dependent manner when EC is contained in lipid vesicles. Furthermore, yeast experiments showed that a strain producing high quantities of EC in its stationary phase decreased in size during EC production. Given caproic acid’s (CA) status as the esterification precursor of EC in yeast, we also compared lipid vesicles containing CA with those containing EC. We found that CA vesicles were smaller than EC vesicles of the same concentration. These results suggest that EC production may function apparently to maintain cell size.

Hard hadronic diffraction is not hard

Hadronic diffractive processes characterized by a hard scale (hard diffraction) contain a nontrivial interplay of hard and soft, nonperturbative interactions, which breaks down factorization of short and long distances. On the contrary to the expectations based on the factorization hypothesis, assuming that hard diffraction is a higher twist, these processes should be classified as a leading twist. We overview various implications of this important observation for diffractive radiation of Abelian (Drell–Yan, gauge bosons, Higgs boson) and non-Abelian (heavy flavors) particles, as well as direct coalescence into the Higgs boson of the nonperturbative intrinsic heavy flavor component of the hadronic wave function.
