Chocolate Pudding and the Effects

on the Final Product

By Sau (Sara) Ming Lam and Yuna Lee

Purpose of Our Experiment

• 2.3% of the adult population in the United States were vegetarians, about 1.4% were vegans (ADA, 2009)

• Increase risks of nutrition deficiencies: calcium, iron, zinc, vitamin B-12, vitamin D, riboflavin, and especially long-chain omega-3 fatty acids

• Essential fatty acids, EPA and DHA cannot be produced in the body

• Fish is the major dietary source

Purpose of Experiment (continued)

• Hemp seeds are naturally rich in omega-3 fatty acids.

• Hemp milk a good alternative of cow’s milk for vegetarians and vegans.

• Recommendation = 500mg/day

• 1 cup (240mL) = 5g omega-3 fatty acids

• More than any of the nondairy milk

Review of Literature

• Vegans tend to have lower blood concentrations of EPA and DHA compare with meat-eaters (Craig, 2009)

• Omega-3 fatty acid supplements are available, but it can cause harm to the body if excessive amount is taken (Craig, 2009)

• Plant0based milks could be good dietary sources for vegetarians and vegans to increase their intake of omega-3 fatty acids

Review of Literature (continued)

• Why we choose hemp milk?

• Optimum balance of omega-6 and omega-3 fatty acids is needed for the body, for vegetarian is between 2:1 and 4:1 (Marsh, Zeuschner, & Saunders, 2011)

• Hemp seeds have 3:1 ratio of omega-6 to omega-3 fatty acids (Vahanvaty, 2009)

• Hemp milk is plant-based, safe for pregnant women, mercury free! (Vahanvaty, 2009)

Review of Literature (continued)

• Function of omega-3 fatty acids ▫ Play a very important role in the growth and

function of nervous system (innis, 2008). ▫ Inadequate intake would result in deficits in the

development of never tissue, leaning ability and visual function (Innis, 2008).

▫ Increased needs for pregnant women for development of the fetus (Craig, 2009)

▫ Maternal intake of omega-3 fatty acid contributes to the DHA levels in breast milk (Kennedy, Luo & Ausman (2012)

• Vegetarian and vegan diets provide many health benefits, but nutrition deficiencies could happen if it is not well-planned

• Based on the results of the sensory evaluation, the experimental samples are quite acceptable to the tasters

• Further research is need to improve the quality of our product
