Clinical and epidemiological characteristics of botulism in the Astrakhan region for the period from 2013 to 2019 are presented. 37 people with a diagnosis of Botulism were under observation. It was found that most often (28 (75.7%) cases) patients associated their disease with the use of canned home-made products. Canned vegetables (cucumbers, tomatoes, vegetable salad, eggplant, cabbage) were consumed by 18 (48.7%) people, mushrooms 10 (27%), dried fish 7 (18.9%), herring-balyk 1 (2.7%) and home-made liver pate-1 (2.7%) patient. The incubation period in the observed patients was on average 2.4 days. It lasted 12 days in 24 (64.9%) patients, 3-5 days in 12 (32.4%) patients, and 6 days in 1 (2.7%) patient. According to the severity of the condition, 17 (45.9%) patients were hospitalized in the intensive care unit. Severe course of the disease was in 17 (45.9%) patients, moderate-in 20 (54.1%) patients. Early and persistent symptoms in all patients were marked muscle weakness, in 78.4% of patients dizziness, in 83.8% of patients difficulty walking and unsteadiness of gait. In 34 (91.9%) patients, the most pronounced symptoms were ophthalmoplegic: blurred vision, fog, flies in front of the eyes, inability to read the text. In General, up to 10 cases of botulism are registered annually in the Astrakhan region. Almost half of the patients (45.9%) have severe botulism. The disease is mostly sporadic and is associated with the use of canned vegetables and home-made mushrooms. In addition, cases of botulism associated with the use of dried fish have become more frequent in the Astrakhan region. Late hospitalization was observed in 1/3 of patients (11 (29.7%) cases) with botulism. This is due to untimely diagnosis at the pre-hospital stage and late access of patients to medical care.

Разработана технология производства овощного пюре из корнеклубней якона, успешно интродуцированного в Республику Северная Осетия - Алания. Изучая химические показатели корнеклубней якона, установлено, что они отличаются богатым химическим составом и содержат сухих веществ - 11,9 %, протеина - 1,88 %, жира - 0,21 %, клетчатки - 1,06 %, золы - 1,48 %, безазотистых экстрактивных веществ - 9,0 %, инулина - 9,0 %, кислотность - 0,22 %. Якон имеет богатый минеральный состав. В 1 кг корнеклубней якона содержится кальция - 0,4 г, фосфора - 0,3 г, железа - 56,1 мг, меди - 0,57 мг, цинка - 3,0 мг, марганца - 12,6 мг, кобальта - 0,03 мг, йода - 0,01 мг, селена - 0,041 мг. Установлено, что в пюре из якона содержание сухих веществ составляет 15,0 %, что соответствует стандартам, содержание жира достигает 4,5 %, а минеральных примесей - 0,003 %. Растительные и посторонние примеси не обнаружены. По внешнему виду пюре из корнеклубней якона представляет собой однородную пюреобразную массу. Запах пюре фруктовый, без постороннего запаха. Вкус сладковатый, полный, насыщенный с приятным послевкусием, без постороннего вкуса. Цвет пюре однородный по всей массе: от желтого до светло-коричневого. Потемнение поверхностного слоя отсутствует. Особую ценность якону придает наличие в его составе инулина - природного полисахарида, на 95% состоящего из фруктозы, что позволяет корневые клубни якона и полученный продукт из него - пюре - рекомендовать как диетический продукт, в том числе людям, страдающим сахарным диабетом и ожирением. Установлено, что целесообразно использовать корневые клубни якона для производства овощного пюре. Пюре из корнеклубней якона по физико-химическим и органолептическим показателям соответствует требованиям стандартов. A technology to produce yacon pips-besed mashed vegetables successfully introduced to the Republic of North Ossetia - Alania is developed. Studying the chemical parameters of yacon pips, it was found that they differ in rich chemical composition and contain dry matter - 11.9 %, protein - 1.88 %, fat - 0.21 %, fiber - 1.06 %, ash - 1.48 %, nitrogen-free extractives - 9.0 %, inulin - 9.0 %, acidity - 0.22 %. Yacon has the rich mineral composition. 1 kg of yacon pips contains calcium - 0.4 g, phosphorus - 0.3 g, iron - 56.1 mg, copper - 0.57 mg, zinc - 3.0 mg, manganese - 12.6 mg, cobalt - 0.03 mg, iodine - 0.01 mg, selenium - 0.041 mg. It was found that mashed yacon contains 15.0 % of dry matter, which meets standards, the fat content reaches 4.5 %, and mineral admixtures - 0.003 %. No plant or extraneous matter was detected. In appearance, the yacon pips-based mash is a homogeneous, mash-like mass. The mash smell is fruity, free of any foreign smell. The taste is sweet, full, rich, with a pleasant aftertaste, free of foreign taste. The color of the mash is homogeneous throughout the whole mass from yellow to light brown. There is no darkening of the surface layer. The special value of yacon is due to inulin in its composition - natural polysaccharide, consists of 95 % fructose, which allows the yacon pips and the resulting product - mash, to be recommended as a dietary product, including people suffering from diabetes and obesity. It was found that it is advisable to use yacon pips for the production of mashed vegetables. Yacon pips-based mash meets standards in physico-chemical and organoleptic parameters.

Abstract The method adopted as official, final action last year was studied collaboratively again this year for calcium in canned vegetable products other than canned whole tomatoes. Twenty-six cans each of whole potatoes with calcium declared on the label and sliced potatoes and lima beans without a label declaration for calcium were analyzed by 13 analysts in 12 laboratories. Again the results were easily reproducible, and the agreement between laboratories was good. Because the method gives continuing precision and low standard deviations, it is recommended for adoption as official, final action for pharmaceutical and vitamin-mineral preparations and canned whole tomatoes, and as official, first action for canned potatoes and lima beans.

Relevance. Most of the pea varieties used in the production of canned vegetables have similar morphological structure of the stalk: shortened internodes, their limited number and location in the upper part of the stalk. The deficiency of such plant architectonics is the limitation of yielding capacity in relation to small number of yielding nodes, yielding capacity instability, and high degree of affliction by plant diseases. The production of pea varieties having an increased number of yielding nodes will allow changing the relation between the nonproductive and reproductive parts to the advantage of the latter.Methods. The pea varieties from the collection of bean cultures laboratories of the Federal Scientific Vegetable Center were used as the research varieties. The main method of work was intervarietal hybridization with subsequent single plant selection. In 2018-2019 the selected lines were seeded in a nursery with an area of 7 m2 . The forms with changed flowering pattern (Pervenets, Ranniy 28-11, Wenson) and the most yielding early and midseason varieties (Dakota, Ranniy Gribovsky 11, Voronezhsky Zelyony, Korsar, Orus, Viola, Zelyonaya Strela, Quartella) were used as parent components. The selection was performed on the basis of the following features: changed flowering pattern, the number of yielding nodes, the number of legumes on a node, as well as the length of a bean and the number of seeds in a legume. A finometer was used for the determination of the green pea hardness.Results. Sample 50-4-19 having a relatively low number of yielding nodes (6, 9) had the highest characteristics and was considerably superior to all the other samples by its yielding capacity during the first and the second harvesting periods (7.24 and 9.55 tons per hectare). The selection of the early forms with the changed flowering pattern and the shift of the attraction centre to the 2nd or to the 3rd node allow carrying out breeding aimed at increasing the early ripeness and the yielding capacity of peas.
