The fat in vegetable foods--tree nuts, peanuts, sunflower seeds, avocado, and olives--can be determined volumetrically by acid digestion of the material and separation of the fat. The assay can be performed conveniently by using the equipment developed for fat determination of milk (Gerber method). The results agree well with those obtained by Soxhlet extraction. The advantages of using the Gerber method for vegetable foods are simplicity, speed, low operation cost, and elimination of the use of inflammable solvents.
植物性食物中的脂肪——如坚果、花生、向日葵籽、牛油果和橄榄——可以通过对材料进行酸消化并分离脂肪来进行容量测定。使用为牛奶脂肪测定开发的设备（格伯氏法）可以方便地进行该测定。结果与索氏提取法得到的结果非常吻合。对植物性食物使用格伯氏法的优点是操作简单、速度快、运营成本低，并且无需使用易燃溶剂。
