The likelihood of choosing alternative source of collagen among consumers: logistic regression approach
2020
: Collagen is the main structural protein of hard and soft tissues in animals and human body. It can
maintain the biological and structural integrity of extracellular matrix and also provides physical support to
tissues. Collagen is much needed nowadays because there are some factors that can deplete the level of collagen
within the body. High sugar consumption, exposure to ultraviolet in the sunlight, smoking, genetic changes,
autoimmune disorder and aging process are the common factors that can damage the collagen within the human
body. Collagen is used in pharmaceutical industries, tissues engineering, food industry, cosmetics, biomedical
industry and medical field. The sources of collagens and gelatins are recently being questioned particularly
among the Muslim users on the status of syariah permissible (halal). This is because the raw materials used in its
manufacture could be sourced from porcine or non-halal slaughtered animals. There are growing concerns
regarding the transfer of diseases from animal sources of collagen to human users and the halal issue on the
sources and manufacturing processes of it. Though currently collagen can be extracted from marine life, the
sources are very limited and this is the main reason why an alternative source is being explored in the current
study. The current study provides an alternative source to the available collagen market using recombinant
collagen-like protein. The present study aims to analyze the factors that contribute to the probability of using this
alternative source of collagen among consumers. Using survey data collected within the area of Wilayah
Persekutuan and Selangor (Klang Valley), the data then are tested empirically using Logistic regression. The
study finds that the probability consumers opt for the alternative source of collagen is significantly determined by
age of consumers and the level of their incomes. The likelihood of the consumers to opt for this alternative source
of collagen is higher among elderly and lower income consumers.
