Opis wynalazkuDescription of the invention
Przedmiotem wynalazku jest sposób wytwarzania spożywczych fosforanów potasu o doskonałej rozpuszczalności w solance technologicznej.The subject of the invention is a method for the production of food potassium phosphates with excellent solubility in technological brine.
W procesach technologicznych stosowanych w przetwórstwie mięsa, drobiu i ryb znajdują zastosowanie sole fosforanowe sodu i potasu, w szczególności difosforany i trifosforany. W najczęściej stosowanych mieszankach funkcjonalnych trifosforany stanowią 60-90% masowych. Difosforany i trifosforany sodu są relatywnie sł abo rozpuszczalne w wodzie, a tym bardziej w solankach technologicznych, które są roztworami NaCl w wodzie o stężeniu bliskim nasycenia w warunkach procesu przetwórstwa mięs (procesy te prowadzi się w temperaturach poniżej 10°C).In technological processes used in the processing of meat, poultry and fish, sodium and potassium phosphate salts, in particular diphosphates and triphosphates, are used. In the most commonly used functional mixtures, triphosphates constitute 60-90% by weight. Sodium diphosphates and triphosphates are relatively poorly soluble in water, and even more so in technological brines, which are NaCl solutions in water with a concentration close to saturation under the conditions of the meat processing process (these processes are carried out at temperatures below 10 ° C).
Z literaturowych danych wynika, ż e znacznie lepsza jest rozpuszczalność odpowiednich soli potasu niż sodu. Otrzymywanie czystych trifosforanów potasu w warunkach znanego procesu technicznego wytwarzania trifosforanów, czyli przy stosunku stechiometrycznym zasady do kwasu jak 5:3 (K2O do P2O5) i przy prowadzeniu procesu kalcynacji (reakcji polikondensacji) w temperaturze 450±50°C rozpuszczalność tych soli jest ograniczona przez równocześnie przebiegającą reakcję tworzenia nierozpuszczalnych metafosforanów potasu, zgodnie z reakcją:Literature data show that the solubility of the corresponding potassium salts is much better than the solubility of sodium. Obtaining pure potassium triphosphates under the conditions of a known technical process for the production of triphosphates, i.e. with a stoichiometric ratio of base to acid as 5: 3 (K2O to P2O5) and carrying out the calcination process (polycondensation reaction) at a temperature of 450 ± 50 ° C, the solubility of these salts is limited by a simultaneous reaction of the formation of insoluble potassium metaphosphates, according to the reaction:
nKH2PO4 (KPO3)n + nH2O konkurencyjną wobec reakcji tworzenia trifosforanu pentapotasu, przebiegającą w tych warunkach:nKH2PO4 (KPO3) n + nH2O competitive to the pentapotassium triphosphate formation reaction, taking place under these conditions:
3H3PO4 + 3KOH >3KH2PO4 + 3H2O3H 3 PO 4 + 3KOH> 3KH 2 PO 4 + 3H 2 O
2KH2PO4 + 2KOH >2K2HPO4 + 2H2O2KH 2 PO 4 + 2KOH> 2K 2 HPO 4 + 2H 2 O
KH2PO4 + 2K2HPO4 K5P3O10 + 2H2OKH 2 PO 4 + 2K 2 HPO 4 K 5 P 3 O 10 + 2H 2 O
W zapisie sumarycznym: 3H3PO4 + 5KOH K5P3O10 + 7H2O.In summary notation: 3H 3 PO 4 + 5KOH K 5 P 3 O 10 + 7H 2 O.
W rezultacie, w normalnie stosowanych warunkach technicznych otrzymuje się bardzo dobrze rozpuszczalny w wodzie trifosforan pentapotasu zanieczyszczony metafosforanem potasu w ilości 1-4% mas. Obecność tego ostatniego związku powoduje widoczne zmętnienie roztworów technologicznych, a w przypadku zastosowania preparatu do nastrzyku i masowania, stwarza problemy z zatykaniem igieł nastrzykowych.As a result, under normal technical conditions, a highly water-soluble pentapotassium triphosphate is obtained, contaminated with potassium metaphosphate in an amount of 1-4 wt. The presence of the latter compound causes visible turbidity of technological solutions, and in the case of using the preparation for injection and massaging, it causes problems with clogging of injection needles.
Sposób według wynalazku polega na tym, że w reakcji kwasu fosforowego z wodorotlenkiem potasu stosuje się nadmiar wodorotlenku potasu od 0,04 do 0,1 mola w odniesieniu do ilości stechiometrycznych właściwych do otrzymania trifosforanu pentapotasu. Zamiast wodorotlenku potasu można zastosować równoważną molowo ilość węglanu potasu. Przy tak prowadzonym procesie udział najbardziej pożądanego trifosforanu pentapotasu obniża się do poziomu poniżej 90% (w zakresie około 65-90% całkowitej ilości fosforanów), ale udział niekorzystnego metafosforanu spada do poniżej 1% (0-0,6% mas.). W mieszaninie pojawia się natomiast difosforan tetrapotasu, korzystny dla mieszanek funkcjonalnych ze względu na silne właściwości kompleksujące żelazo na drugim stopniu utlenienia i tym samym utrzymującym różową barwę przetworów mięsnych.The method according to the invention consists in the use of an excess of potassium hydroxide of 0.04 to 0.1 mol in the reaction of phosphoric acid with potassium hydroxide, based on the stoichiometric amounts appropriate to the preparation of pentapotassium triphosphate. Instead of potassium hydroxide, an equivalent molar amount of potassium carbonate may be used. With such a process, the proportion of the most desirable pentapotassium triphosphate drops to a level below 90% (in the range of about 65-90% of the total amount of phosphates), but the proportion of unfavorable metaphosphate drops to below 1% (0-0.6% by weight). On the other hand, tetrapotassium diphosphate appears in the mixture, advantageous for functional mixtures due to the strong iron complexing properties in the second oxidation state and thus maintaining the pink color of meat products.
Sposób według wynalazku przestawiono w przykładzie.The method according to the invention is illustrated in the example.
P r z y k ł a d: Do reaktora wyposażonego w mieszadło i płaszcz grzewczo-chłodzący wprowadzono 2500 g kwasu fosforowego spożywczego zawierającego 75,8% P2O5. Do kwasu zadozowano powoli 4230 g roztworu KOH o stężeniu 45% mas. Proces neutralizacji prowadzono w temperaturze 80±2°C. Otrzymano roztwór odpowiednich ortofosforanów potasu, który skierowano do suszenia rozpryskowego, gdzie następuje odparowanie wody. Proces prowadzono tak, aby otrzymany półprodukt zawierał nie więcej niż 5% wilgoci. Następnie półprodukt kalcynowano na tacach metalowych kwasoodpornych w temperaturze 450°C przez 60 minut przy zastosowaniu grubości warstwy kalcynowanej nie większej niż 2 cm. Otrzymany produkt zawierał poniżej 0,3% części nierozpuszczalnych w wodzie. Części rozpuszczalne zostały zanalizowane metodą wysokosprawnej chromatografii cieczowej (HPLC) na zawartość form fosforanów. Analiza wykazała 70,5% cz. wag. P2O5 w formie trifosforanów, 29,0% difosforanów i 0,5% całkowitego P2O5 w formie ortofosforanów.Example: 2500 g of food grade phosphoric acid containing 75.8% P2O5 were introduced into a reactor equipped with a stirrer and a heating and cooling jacket. 4230 g of KOH solution with a concentration of 45% by weight were slowly dosed into the acid. The neutralization process was carried out at the temperature of 80 ± 2 ° C. A solution of the corresponding potassium orthophosphates was obtained, which was directed to spray drying, where the water was evaporated. The process was carried out so that the obtained semi-finished product contained no more than 5% of moisture. Then, the semi-finished product was calcined on acid-resistant metal trays at a temperature of 450 ° C for 60 minutes with a calcined layer thickness not exceeding 2 cm. The obtained product contained less than 0.3% water-insoluble parts. The soluble parts were analyzed by high performance liquid chromatography (HPLC) for the content of phosphate forms. The analysis showed 70.5% bp. wt. P2O5 as triphosphate, 29.0% diphosphate and 0.5% total P2O5 as orthophosphate.
