Detailed Description:

In human breast milk, and in most infant formulas more than 98% of this milk fat is in the form of triglycerides, which contain saturated and unsaturated fatty acids esterified to glycerol. Fatty acids in human milk-fat have a highly specific positional distribution on the glycerol backbone and this specific configuration is known to have a major contribution to the efficacy of this nutrient absorption.

Palmitic acid (C16:0), the major saturated fatty acid, is predominantly esterified to the sn-2 (β) position of the triglyceride in human milk. In contrast, palmitic acid in standard infant formulas is esterified to the sn-1 and sn-3 positions.

Infants fed with high sn-2 palmitic acid formula had softer stools, less constipation and better calcium absorption as compared to standard infant formula.

InFat™ is structured triglyceride fat ingredient with high levels of palmitic acid at sn-2 position.

The primary objective of this trial is to demonstrate that feeding Chinese term infants, with formula having proportion of palmitate in the sn-2 position comparable to human milk, reduces calcium-soaps formation.


Ages Eligible for Study:   up to 8 Days   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Term infants: gestation 37-40 weeks
  • Birth weight 2500-4000 g
  • Apparent good health
  • The infant is a product of normal pregnancy and delivery.

Exclusion Criteria:

  • Any maternal disease (psychological or disabled) or socioeconomic problems that may interfere with the mother's ability to take care of her infant
  • Major congenital abnormality or chromosomal disorder with a clinical significance that can be detected at birth, clinically significant
  • Disease requiring mechanical ventilation or medication treatment at the first week (not including photo treatment for infantile hepatitis)
  • Born with a 5- or 10-minute Apgar score <7
  • Any suspected or known metabolic or physical limitations interfering with feeding or normal metabolism (require a special formula)
  • Breast-feeding for a week or over.
  • Any other reason that, in the opinion of the investigator, prevents the subject from participating in the study.
