Method of producing protein fibres
专利摘要:
A process of continuously forming pH modified protein filaments from a proteinaceous material is disclosed wherein an aqueous slurry of the proteinaceous material is formed having a proteinaceous solids content of between about 0.5 and 35% by weight. Discrete filaments are formed by conducting the slurry under pressure through a heat exchange zone and heating the slurry to a temperature which is above 240 DEG F. whereby the protein is subjected to such temperature for a sufficient period of time so that elongated filaments are thereafter separated from the remaining constituents of the slurry. The heated slurry is then continuously removed from said heat exchange zone through a back pressure creating orifice whereby discharge of said filaments from the heat exchange zone to a collecting zone is controlled by confining the stream of said filaments to within a total angle of between about 4 DEG and 90 DEG . A pH elevating material is then injected into the stream of filaments during confinement in order to modify the pH of the filaments to a pH of above about 6.0 and preferably between about 6.0 and 7.0. It has been determined that pH modified filaments produced in the above manner are highly functional for meat extender applications, yet pH modification in the above manner provides the maximum yield of protein filaments from a given weight of proteinaceous slurry since the pH of the slurry is not altered prior to filament formation. 公开号:SU921450A3 申请号:SU762426457 申请日:1976-12-02 公开日:1982-04-15 发明作者:Энтони Хоер Ральф;Хенри Стюарт Майкл 申请人:Ральстон Пьюрина Компани (Фирма); IPC主号:

The invention relates to techniques for the production of protein fibers from protein material used for additives to meat products in the food industry. b There is a known method for producing a protein food product, which consists of preparing a suspension of defatted soybeans, adding HC to pH 4.3, the resulting precipitate is dried, added to the initial precipitate in an amount providing 35% humidity, the pH is adjusted to 7, and the resulting mixture is fed to an extruder, at the exit of which the protein fibers have a temperature of -5 150 ° C [1]. There is also known a method for producing protein fibers, comprising preparing an aqueous suspension from plant materials, heating the suspensions by passing through a heat exchanger with a solids content of 0.5-35 wt.%, Forcing the heated suspension through a diaphragm under a pressure of 25 to obtain protein fibers and unloading fibers into the collection area [2]. Formed protein fibers are widely used in the production of a wide variety of food products with improved aesthetic properties and taste. However, these known methods do not involve adjusting the pH of the suspension prior to the formation of fibers. in the desired range from 6.0 to 7.0, as a result of which these wafers cannot be used as a source of additives to foods such as meat. Protein fibers having a pH in the range of 6.0 to 7.0 have better culinary properties when added to meat than those having a lower pH of 4.5 to 5.5. The closest to the proposed technical essence and the achieved result is a method of producing protein fibers, which provides for the preparation of an aqueous suspension of a dilute protein-containing raw material having a pH of 4.5-5.0 with a solid content of 0.5–35 wt.%, heating the suspension to a temperature of 116-157 ° C, forcing the heated suspension under pressure to obtain protein fibers, unloading the fibers into the collection zone, followed by the introduction of sodium carbonate to establish a pH of 6 to 7 [3]. However, protein fibers obtained by a known method cannot be used as additives to meat products and their yield is low. The chain of the invention is to increase the yield of fibers used as up to: 15 additives for meat products. This goal is achieved in that according to the proposed method for producing protein fibers, which provides for the preparation of an aqueous suspension from a soluble thermal protein-containing raw material having a pH of 4.5-5.0 with a solids content of 0.5-35 wt.%, Heating the suspension to a temperature of 116157 ° C, forcing the heated suspension under pressure to obtain protein fibers, discharging the fibers into the collection zone, followed by the introduction of sodium carbonate until a pH of 6 to reach. 7, the introduction of sodium carbonate into protein fibers is carried out immediately before unloading them into the collection zone by injecting sodium carbonate into the stream of protein fibers. The aqueous sodium carbonate solution is preheated. The introduction of sodium carbonate into protein fibers provides a modification of their pH, preferably between 6th and 7th, without reducing the yield of protein fibers or changing their functional properties, while ensuring maximum yield of protein fibers from a given weight of the protein suspension, since the pH does not change until fiber formation.

Next, an aqueous solution of sodium carbonate is introduced into the protein fibers until a pH of 6 to 7 is established by injecting it through the nozzles 12 into a stream of protein fibers immediately before they are discharged into the collection zone 7. Before injection, an aqueous solution of sodium carbonate with a concentration of 8 to 13 wt.% Is heated up to about 121 ° C. Example. A protein suspension, comprising 438.8 kg of isolated soy protein with a solids content of 24.0 wt%, is mixed with 11.7 kg of coke oil, and the pH of the suspension is adjusted to 4.7 by adding 50% sodium hydroxide solution. The protein suspension is mixed in a colloid mill and sent through a heat exchanger with mowing. 151 ° C.

The proposed method for producing protein fibers can increase the yield of fibers used as additives in the production of a wide variety of food products. The resulting protein fibers can serve as additives to meat products, giving them improved aesthetic properties, good taste and better culinary properties. In addition, the protein protein obtained reduces the cost of various types of meat products when introduced into them.
