Abstract
<p>Lactose intolerant consumers can consume milk if there is a lactase enzyme that breaks down lactose in dairy products first. Enzyme immobilization is an enzyme attached to the material and not dissolved in the product stream repeatedly. The process of reducing lactose levels by immobilizing the lactase enzyme in milk can be a claim that the milk is low in lactose and lactose-free. This review aims to identify recent and significant advances in enzyme immobilization technology, generate ideas for future research areas, and help identify critical gaps in research to find solutions. The highest percentage of enzyme immobilization until almost 100% uses an alginate matrix and a cycle more than twice. That indicates that the enzyme immobilization method is very effective in making low-lactose milk in the food industry in this particular. Some benefits of enzyme immobilization for the food industry are: producing low-lactose milk and improving the quality or the value of dairy products by increasing the product’s softness, digestibility, and sweetnes. In addition, it can speed up the ripening process of cheese and is a source of sugar in confectionery, feedstuffs, soft drinks, candy, cakes, ice cream, flavored milk, desserts, and molasses.</p><p>Keywords: Milk, lactose intolerance, anzyme immobilization, alginate.</p><p> </p><p><strong>Abstrak</strong></p><p>Konsumen intoleransi laktosa dapat mengonsumsi susu apabila ada enzim laktase yang memecah laktosa terlebih dahulu. Kadar laktosa dapat diturunkan dengan cara imobilisasi enzim laktase pada susu sehingga memiliki laktosa yang rendah atau bebas laktosa. Imobilisasi enzim merupakan enzim yang melekat pada bahan dan tidak terlarut dalam aliran produk sehingga dapat digunakan berulang kali. Naskah ini mengungkapkan kemajuan teknologi imobilisasi enzim dan membantu menemukan solusi dalam menurunkan kadar laktosa pada susu. Tingkat imobilisasi enzim yang tinggi hingga mencapai hampir 100% menggunakan matriks alginat dan siklus yang dapat digunakan lebih dari dua kali menunjukkan metode imobilisasi enzim sangat efektif menekan kadar laktosa pada susu atau pada industri pangan umumnya. Manfaat imobilisasi enzim bagi industri pangan selain untuk memproduksi susu rendah laktosa juga dapat meningkatkan kualitas atau nilai produk susu dengan meningkatkan kelembutan, daya cerna, dan rasa manis produk. Selain itu, dapat mempercepat proses pematangan keju dan sumber gula dalam penganan, bahan pakan, minuman ringan, permen, kue, es krim, susu berperisa, makanan penutup, dan molase. <br /><br />Kata kunci: Susu, intoleransi laktosa, imobilisasi enzim, alginat</p>
