The materials and chemicals that have been used in this study are stated as follows: commercial grade (Ingeo™ 2003D (NatureWorks)) poly (lactic acid) (PLA) with a melt flow rate of 6 g/10 min; lactic acid (88%, Loba Chemie Pvt. Ltd. India); sodium chloride (Assay 99%); chloroform (99.99%, Fisher Chemicals the Scientific UK); sodium hydroxide (99.8%, LABKEMICAL India); acetone (99.5% Ranchem industry and trading); broiler skin (collected from the local market) and distilled water.
Lactic acid
Manufactured by Loba Chemie
Sourced in India
Lactic acid is a colorless, odorless, and water-soluble organic acid produced by the fermentation of carbohydrates. It is a common ingredient in various industries, including food, pharmaceutical, and cosmetic applications.

The procedure involved the use of 8 g of methylcellulose gel (Xi'a Geekee Biotech Co., Ltd, Shaanxi, China). A demineralizing solution was prepared combining 100 ml of 0.1 M lactic acid (LobaChemie Pvt. Ltd., Mumbai, India), with a fixed pH of 4.6, adjusted using a 45% KOH solution (HiMedia® laboratories, Pa, USA) [17 (link)]. The mixture was then stored in an incubator at 37 °C for a period of 7 days. Throughout the incubation period, the pH was maintained at 4.5 using a digital pen-type pH meter (SD Fujian, China) [18 (link)].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
