Description

Пзвестные способы получени  препарата каротина, включающие выращивание гриба Blakeslea trispora иа питательной среде с последующим вакуумным высушиванием, не позвол ют получить препарат с высокой сохран емостью без добавлени  антиоксидантов .The well-known methods for preparing a carotene preparation, including cultivating the Blakeslea trispora mushroom in a nutrient medium followed by vacuum drying, do not make it possible to obtain a preparation with high persistence without the addition of antioxidants.

По предложенному способу выращивание гриба Blakeslea trispora провод т на среде, содержащей: кукурузной муки в смеси с отруб ми (1:1) 90-90,Гэ/о, кукурузного экстракта 1,9-2%; керосина до 4о/о и растительного масла до 4(/о, а высушивание производ т при температуре 50-60°С.According to the proposed method, the cultivation of the Blakeslea trispora fungus is carried out on a medium containing: corn flour mixed with bran (1: 1) 90-90, Ge / o, corn extract 1.9-2%; kerosene up to 4o / o and vegetable oil up to 4 (/ o), and drying is performed at a temperature of 50-60 ° C.

Благодар  этому повышаетс  сохран емость препарата каротина без добавлени  антиоксидантов.This increases the retention of the carotene preparation without the addition of antioxidants.

Способ заключаетс  в следующем. Посевной материал получают в виде спор Blakeslea trispora + и - вариантов, которые выращивают на картофельном агаре, каждый отдельно , в течение 7-10 дней при температуре 28°С. Полученные споры смывают с агара физиологическим раствором или используют вместе с питательной средой. В качестве посевного материала можно примен ть и мицелиальную культуру гриба, выращенную на плотной зерновой среде.The method is as follows. Seed material is obtained in the form of Blakeslea trispora + and - spores, which are grown on potato agar, each separately, for 7-10 days at a temperature of 28 ° C. The resulting spores are washed from the agar with saline or used with a nutrient medium. The mycelial culture of the fungus grown on a dense cereal medium can also be used as a seed.

ную муку грубого помола или кукурузную муку в смеси с отруб ми (1:1), в которую после увлажнени  водопроводной водой до 30-35% добавл ют растительное масло, керосин и кукурузный экстракт. Состав ферментационной среды следующий, о/о к муке:wholemeal flour or corn flour in a mixture with cuts (1: 1), in which, after moistening with tap water to 30-35%, add vegetable oil, kerosene and corn extract. The composition of the fermentation medium is the following, o / o to flour:

кукурузный экстракт (сырой) 1,9-2 керосиндо 4corn extract (raw) 1,9-2 kerosene 4

растительное маслодо 4vegetable butter 4

В среде устанавливают рН 6,2, раскладывают ее в кюветы слоем 2-2,5 см, стерилизуют в автоклаве при 120°С в течение 40- 60 мин. После этого среду охлаждают до 30°СThe medium is adjusted to pH 6.2, laid out in cuvettes with a layer of 2-2.5 cm, sterilized in an autoclave at 120 ° C for 40- 60 minutes. After that, the medium is cooled to 30 ° C

и засевают суспензией спор гриба - продуцента каротина из расчета 4-5 млн. спор + и - вариантов или около 50 г мицелиальной культуры гриба на 1 кг воздущного сухого сырь . При посеве добавл ют воду в количестве , обеспечивающем увлажнение среды до 60-65%, и 50 ед/г окситетрациклина дл  предупреждени  бактериальной инфекции. Ферментацию каротина провод т в термостате в течение 3-4 суток. По окончании ферментации гриб вместе с питательной средой и продуктами биосинтеза высушивают в калориферной сушилке при температуре 50- 60°С и размалывают. Сухой препарат содержит в 1 г до 400 мкг каротина и сохран етс  3 -4and seeded with a suspension of spores of the fungus - the producer of carotene at the rate of 4-5 million spores + and - variants, or about 50 g of mycelial culture of the fungus per 1 kg of dry air. When sowing, water is added in an amount that provides a moistening of the medium up to 60-65%, and 50 units / g of oxytetracycline to prevent bacterial infection. Fermentation of carotene is carried out in a thermostat for 3-4 days. At the end of the fermentation, the fungus, together with the nutrient medium and products of biosynthesis, is dried in a calorifer dryer at a temperature of 50-60 ° C and ground. The dry preparation contains in 1 g up to 400 µg of carotene and is kept 3-4.
