摘要

牛奶是现存最完整的食物之一。在过去的几十年里，由于降低了心血管疾病和相关疾病的风险，牛奶FA已被证明可以改善人类健康。本研究的目的是评估近红外光谱（NIRS）反射分析预测牧区奶牛鲜奶营养价值、脂肪酸（FA）成分和健康指数的可行性。近红外光谱法对鲜奶样品中的动脉粥样硬化性和血栓形成性指数以及其他FA比率的预测是准确的。此外，NIRS获得的校准模型为牛奶的健康FA（如ω-3和共轭亚油酸（CLA））的常规定量提供了机会，并在乳制品行业应用于食品标签，在农场层面应用于奶牛饮食管理。

Determination of nutritional health indexes of fresh bovine milk using near infrared spectroscopy

Bovine milk is one of the most complete foods that exist. During the last decades, milk FA have shown to improve human health due to the reduction in risk of cardiovascular disease and related pathologies. The aim of this study was to evaluate the feasibility of near infrared spectroscopy (NIRS) reflectance analysis to predict the nutritional value, fatty acid (FA) composition, and health index of fresh milk from dairy cows of pastoral systems. The prediction of Atherogenicity and Thrombogenicity indexes, along with other FA ratios in fresh milk samples by NIRS were precise and accurate. In addition, the calibration model obtained by NIRS provides an opportunity for the routine quantification of milk’s healthy FA such as omega-3 and conjugated linoleic acid (CLA), with applications in the dairy industry for food labeling, and at the farm level for management of the dairy cow’s diet.

期刊介绍： Grasas y Aceites is a peer-reviewed journal devoted to the publication of original articles concerning the broad field of lipids, especially edible fats and oils from different origins, including non acyl lipids from microbial origin relevant to the food industry. It publishes full research articles, research notes, reviews as well as information on references, patents, and books. Grasas y Aceites publishes original articles on basic or practical research, as well as review articles on lipid related topics in food science and technology, biology, (bio)chemistry, medical science, nutrition, (bio)technology, processing and engineering. Topics at the interface of basic research and applications are encouraged. Manuscripts related to by-products from the oil industry and the handling and treatment of the wastewaters are also welcomed. Topics of special interest to Grasas y Aceites are: -Lipid analysis, including sensory analysis -Oleochemistry, including lipase modified lipids -Biochemistry and molecular biology of lipids, including genetically modified oil crops and micro-organisms -Lipids in health and disease, including functional foods and clinical studies -Technical aspects of oil extraction and refining -Processing and storage of oleaginous fruit, especially olive pickling -Agricultural practices in oil crops, when affecting oil yield or quality
