製作肉丸的幾個步驟
肉丸是一種非常有名的食品,你知道製作肉丸的步驟是什麼嗎?在肉丸加工中應該注意哪些預防措施?
第1步:原料處理的肉丸製作
原料預處理主要包括原料分段和沖洗。分段的目的是方便下一步的原料破碎。沖洗的主要目的是去除原料中的水溶性蛋白質和其他影響品質的物質,如內源酶、殘血、色素、殘留脂肪、腥味物質、無機鹽、殘留骨屑等,以提高成品肉丸的品質和整體感官品質。

其中,沖洗溫度和用水量是兩個主要的影響因素。過高的漂洗溫度會導致部分或全部原料中的蛋白質變性,進而影響後續加工中蛋白凝膠性能的形成,導致蛋白網絡無法良好形成,最終使成品的彈性降低、口感差、感官品質整體下降。雖然大量用水會降低成品的原始風味,但會提升整體感官品質。研究發現,沖洗水溫低於10°C,水量為原料重量的4倍時,是最佳的預處理工藝。
第2步:破碎工藝

Before adding auxiliary materials and chopping and mixing the ingredients into minced meat, the crushing of the raw meat is a necessary process operation. , to avoid uneven mixing of raw and auxiliary materials in the next step of chopping and mixing, excessive chopping and mixing time, and high temperature, which will affect the quality of the product. The key to the crushing process lies in the control of temperature and the selection of crushing particle size. For example, the high temperature of the beef ball machine causes protein denaturation and solidification, which affects the subsequent process. If the crushing particle size is too large, the time required for the chopping and mixing process will be prolonged, and at the same time, it will easily lead to uneven mixing; if the crushing particle size is too small, a gel will be formed between the meat particles in advance, hindering the next step of mixing. Therefore, the temperature is generally controlled below 10 °C, and the crushing particle size is generally selected at 4~5mm.
第3步:切碎與混合工藝

In the meatball production process, the function of chopping and mixing is to cut and break the intermuscular connective tissue and muscle fibers in the muscle tissue, and destroy the integrity of the sarcolemma, endomysium, and muscle fibers. The force between the chopping knife and the meat particles increases, the temperature of the raw material increases, the protein is denatured and solidified, and the molecules are cross-linked to form a network structure, which encapsulates water molecules and other components, and finally becomes a complex structure. Gel aggregates.
切碎時間不足會導致原料破碎不充分,過長則會提高原料溫度,一方面會導致鹽溶性蛋白變性,影響產品品質。因此,切碎過程中通常加入碎冰塊或冰水來控制原料溫度不超過15°C。文獻也顯示,切碎溫度應控制在8~10°C。使用切碎機進行切碎。
第4步:肉丸成型的步驟

的 meatball forming machine uses a meatball forming machine, put the prepared minced meat into the machine, and the meatball forming machine will make the raw materials into meatballs of equal size. Filled meatballs can be made, or solid meatballs. The meatballs can be made of various materials, such as beef balls, chicken meatballs, and fish meatballs, as well as vegetarian meatballs. There are no restrictions on raw materials.
第5步:烹飪與炸制工藝
肉丸加工技術中烹飪的目的是使原料中的蛋白質變性,形成穩定的形態結構。烹飪過程中不同的時間和溫度條件會導致產品的物理性質、蛋白質、脂肪和風味產生不同程度的變化,例如水分和汁液的流失、肉的硬度和顏色的變化、脂肪的溶解以及揮發性物質的逸出等。其中,隨著溫度變化的蛋白質變性程度對肉丸的品質影響最為明顯。為避免因汁液流失而導致的品質和產量下降,烹飪溫度和時間的控制通常採用二次烹飪法,即:在60~70℃預煮3~10分鐘,然後迅速升溫至80~90℃,再煮5~15分鐘。一次烹飪則為85~90℃,持續15~20分鐘。研究發現,慢火烹調(98℃,15分鐘)能促進低脂肉丸的感官品質。雖然炸制過程可能對肉丸的感官品質、營養價值和安全性產生一定潛在影響,但控制適當的油溫和炸制時間不僅能改善產品的色澤和風味等感官品質,還能在肉丸表面形成堅硬的外殼,從而減少烹飪過程中活性成分的流失。油溫的選擇根據肉丸的原料和配方而異,通常在160~180℃,炸3~5分鐘;或在180~200℃,炸2~3分鐘。
第6步:快速冷凍工藝
快速冷凍的目的是為了避免在存儲、運輸和銷售過程中肉丸受到微生物污染。肉丸富含多種營養素,易在室溫下受到微生物感染,導致感官品質和保質期嚴重下降。因此,肉丸加工完成後,必須冷卻並冷凍後再包裝。冷卻和冷凍的溫度與時間直接影響產品的感官品質和保質期。如果冷凍溫度過低且時間過長,會形成大冰晶,分布不均,破壞產品的組織狀態;如果冷凍溫度不夠低,微生物的生長繁殖無法有效控制。因此,肉丸加工中常用的快速冷凍方法是先預冷產品,使其溫度降至0~4°C,然後在-25°C以下的環境中快速將核心溫度降至-18°C。
