Q.3
The major protein complex in the surimi production belongs to the group of
- Protein Composition of Fish Muscle and Surimi:
- Fish muscle proteins are classified into three major fractions:
- Sarcoplasmic Proteins ($20-30\%$): Water-soluble enzymes and myoglobin; washed out during surimi water-washing steps because they impair gel formation.
- Stroma Proteins ($3-10\%$): Insoluble connective tissue collagen and elastin.
- Myofibrillar Proteins ($65-75\%$): Salt-soluble structural contractile proteins (Myosin, Actin, Actomyosin, and Tropomyosin).
- Concentrated myofibrillar proteins (actomyosin) are the functional backbone of surimi, unfolding and cross-linking to form the firm, elastic heat-induced gel (kamaboko) structure.
- Correct Option: Option 2 (Myofibrillar Proteins).
