Additional reasons for gaining a better comprehension of the effect of lignin on the permanence of paper obtain from the increased use of recycled paper , which may have an appreciable lignin content , and a new trend in paper manufacture , where small amounts of lignin are reintroduced in the paper-making process . In 1993 , DOE discovered that some of the longest stored oil had accumulated an excessive gas content . Therefore , the identity specification for low erucic acid rapeseed oil ( 21 CFR 184.1555 ( c ) ( 1 ) ) stipulates that , chemically , the oil is a mixture of triglycerides , composed of both saturated and unsaturated fatty acids , with an erucic acid content of no more than 2 percent of the component fatty acids . The raw water in this well had an average iron content of 0.074 mg / L and manganese content of 0.013 mg / L . Fat has an energy content of 9.4 kcal / g and protein 5.7 kcal / g. Assuming that fat tissue has 15 % as water , the stored energy of tissue fat is 8 kcal / g. Similarly , since lean tissue has an average protein content of 20 % , it has an energy storage value of 1.2 kcal / g. in developed countries , yielding 45.4 and 61.6 kg per day of dry biomass , respectively , with an average protein content of 42 per cent . Low erucic acid oil derived from Brassica juncea contains five principal fatty acids ( palmitic , stearic , oleic , linoleic and linolenic ) and has an erucic acid content of approximately 0.2 % .
