is widely used fermented milk product in India. Low Density Polyethylene (LDPE) is the most extensively used packaging material for in India. The present study was conducted to develop the analytical methods for extraction and migration of chemical additives from LDPE into . Characterization of packaging materials collected from five different firms was done by Fourier Transform Infrared Spectroscopy. Focused ultrasound solid liquid extraction method was observed to be better as compared to solid liquid extraction method as the former extracted maximum additives from the LDPE. Out of total 76 chemical additives extracted from LDPE, only eight (10.52%) matched with the existing positive list of polyolefins prescribed by Bureau of Indian Standads (BIS). The overall migration of chemical additives from all the LDPE samples was below their maximum limit as given by BIS standards. Chemical additives which migrated into the simulants included the antioxidants, fatty acids and their derivatives, unreacted hydrocarbons, plasticizers, lubricants and surfactant etc.
在印度是广泛使用的发酵乳制品。低密度聚乙烯（LDPE）是印度用于[此处原文缺失相关内容]的最广泛使用的包装材料。本研究旨在开发从LDPE中提取化学添加剂并使其迁移到[此处原文缺失相关内容]中的分析方法。通过傅里叶变换红外光谱法对从五家不同公司收集的[此处原文缺失相关内容]包装材料进行了表征。与固液萃取法相比，聚焦超声固液萃取法被认为更好，因为前者从LDPE中提取的添加剂最多。从LDPE中提取的76种化学添加剂中，只有8种（10.52%）与印度标准局（BIS）规定的聚烯烃现有阳性清单相匹配。所有LDPE样品中化学添加剂的总体迁移量低于BIS标准规定的最大限量。迁移到模拟物中的化学添加剂包括抗氧化剂、脂肪酸及其衍生物、未反应的烃类、增塑剂、润滑剂和表面活性剂等。
