Preterm Infant Nutritional Ingredients Development
Preterm and low birth weight infants have underdeveloped digestive systems and limited nutrient absorption, requiring highly precise and bioavailable nutrition. Traditional infant ingredients often struggle to meet these needs in terms of mildness, safety, and stability. Aprofood develops tailored nutrition ingredients using structural optimization, microencapsulation, and carrier technologies to enhance absorption and ensure safe, effective, and application-ready solutions for these vulnerable infants.

Critical Nutritional Requirements for Preterm and Low Birth Weight Infants
Preterm and low birth weight infants have unique nutritional needs due to their underdeveloped digestive systems, limited absorption capacity, and ongoing metabolic development. Meeting these needs requires carefully designed nutrition ingredients that are gentle, highly bioavailable, and compatible with various infant formula formats.
Limited Digestive and Absorption Capacity
Insufficient gastric acid secretion, pancreatic enzymes, and bile production lead to low absorption efficiency for proteins, fats, and certain trace elements. These infants have a higher dependence on mild proteins, small peptides, low-molecular-weight carbohydrates, and lipids.
High Growth and Developmental Demands
Rapid development of body weight, bones, muscles, and the nervous system results in high requirements for energy, protein, minerals, and fatty acids. Inadequate nutrient utilization can easily affect weight gain and organ development.
Immature Immune System
They are more susceptible to oxidative stress due to underdeveloped antioxidant defense systems. Trace supplementation of vitamins, minerals, and plant-derived bioactive compounds is often necessary to support immune function and maintain oxidative balance.
Formulation and Processing Compatibility Challenges
Formulations for preterm infants often include liquids, powdered formulas, semi-solid foods, or fortified dairy products. Nutritional ingredients must remain stable under low-temperature, low-shear processing conditions to prevent sedimentation, separation, or flavor deterioration.
Therefore, developing nutrition ingredients for preterm and low birth weight infants requires careful consideration not only of nutrient selection but also of solubility, absorption efficiency, mildness, processing compatibility, stability, and suitability across multiple application formats.
Our Service

Aprofood provides a comprehensive development pathway for infant nutrition ingredients, covering scientific research, raw material screening, structural optimization, and practical application. Through precise design of proteins, amino acids, lipids, polysaccharides, minerals, trace elements, and plant-derived bioactive components, Aprofood helps companies develop safe, highly absorbable, and stable nutrition ingredients for infants.
Protein and Peptide Ingredient Development
Preterm and low birth weight infants have limited protein digestion capacity, making small peptides and easily absorbable amino acids critical raw materials. Aprofood conducts scientific screening of different protein sources and optimizes enzymatic hydrolysis to achieve highly digestible small peptides.
- Small peptide and amino acid combination design: Protein sources are selected based on infant digestive characteristics, with molecular weight control and peptide optimization to enhance gastrointestinal absorption while minimizing potential immune reactions. Microencapsulation or carrier coating technologies can further improve stability in acidic environments.
- Mild processing and solubility optimization: Low-temperature, low-shear processing preserves protein and peptide structures, ensuring rapid dissolution and uniform dispersion in liquids, powdered formulas, and dairy products.
- Sensory and safety improvement: Flavor optimization techniques reduce bitterness or off-tastes, improving texture and palatability for easier infant ingestion, while ensuring safety and mildness.
- Multi-dosage form compatibility: Protein and peptide ingredients can be applied in liquids, powders, semi-solid, and fortified dairy products, providing flexible options for product development.
Lipid and Essential Fatty Acid Ingredient Development
Lipids are crucial for neural development and weight gain in preterm infants, but absorption capacity is limited. Aprofood provides multilayer optimization for key lipids such as DHA, ARA, and MCTs.
- High absorption lipid design: Emulsification, nano-dispersion, or microencapsulation techniques enhance uniformity of lipids in liquids, powders, and dairy products.
- Stability and antioxidant treatment: Lipids are prone to oxidation; protective coatings, oxygen-sensitive encapsulation, and formulation stabilization ensure activity is maintained during storage, transportation, and processing.
- Formulation compatibility: Lipid ingredients are compatible with protein, mineral, and carbohydrate systems, preventing sedimentation, separation, or caking and ensuring long-term stability.
- Multi-scenario application: Lipids can be used in powdered formulas, fortified dairy products, liquid beverages, and semi-solid nutritional products to meet diverse production needs.
Mineral and Trace Element Ingredient Development
Minerals and trace elements are essential for infant bone, neural, and metabolic development. Preterm infants have lower absorption capacity, requiring mild, highly absorbable raw materials.
- High absorption mineral design: Calcium, iron, zinc, magnesium, and others are provided in chelated or organic-complexed forms to enhance bioavailability and reduce gastrointestinal irritation.
- Mildness and digestive tolerance optimization: Dissolution rates are controlled to improve gastrointestinal tolerance and allow synergistic use with proteins, lipids, and carbohydrates.
- Multi-element blend strategy: Mineral blends are designed according to infant absorption mechanisms to prevent antagonism and improve overall absorption efficiency.
- Processing compatibility: Mineral ingredients remain stable in powdered formulas, liquids, and dairy products, ensuring uniformity and stability in formulations.
Carbohydrate and Energy Support Ingredient Development
Preterm infants have high energy needs but immature digestive systems, making low-molecular-weight, easily absorbable carbohydrates essential.
- Low-molecular-weight carbohydrates: Optimized ratios of glucose, maltodextrin, and lactose enhance solubility and absorption rates in liquids, powders, and dairy products.
- Energy density optimization: Carbohydrate and lipid ratios are balanced to provide high energy while reducing gastrointestinal burden.
- Mild processing and palatability design: High temperatures or shear forces are avoided to preserve carbohydrate structure, ensuring gentle taste and digestibility in powdered and liquid products.
- Multi-scenario application: Suitable for fortified dairy products, liquid nutritional beverages, powdered formulas, and semi-solid products to provide precise energy supplementation.
Dietary Fiber and Prebiotic Ingredient Development
Dietary fiber and prebiotics play key roles in infant gut development, but preterm infants have sensitive digestive systems requiring mild and highly absorbable ingredients.
- Low-stimulation fiber design: Molecular weight and structure are controlled to reduce bloating and digestive discomfort.
- Prebiotic blend optimization: Galacto-oligosaccharides (GOS), fructo-oligosaccharides (FOS), and soluble fibers are stabilized to improve storage and processing tolerance.
- Multi-dosage form compatibility: Can be added to powdered formulas, liquid beverages, and dairy products, ensuring palatability and functionality.
Antioxidant and Cellular Homeostasis Support Ingredient Development
Preterm infants have immature antioxidant systems and require nutritional ingredients to support cellular homeostasis.
- Heat-sensitive antioxidant design: Vitamins and plant polyphenols are protected through microencapsulation or carrier coating.
- Multi-system compatibility: Ensures even dispersion and preserved activity in liquids, powders, and dairy formulations.
- Mildness and safety control: Flavor and irritancy are optimized to protect infant gastrointestinal tolerance.
- Diverse applications: Suitable for liquids, powders, dairy products, and semi-solid nutritional items to deliver antioxidant and homeostasis-supporting functions effectively.
