Feeding The Future Meat Doesn’T Come Cheap, Lukas C. Southard
Capstones
Cultured – or as it is referred to by companies innovating the technology clean – meat is expected to be the next innovation to change the way the world gets its animal protein. Meat from animal cells grown in a lab seems like science fiction but it is around the corner from hitting your supermarket shelves. The technology has been developed but how these companies intend on scaling up their production to meet retail demands remains a mystery. So far companies have relied on seed and early stage investment from venture capital companies and private sources to fund research. Predictions …

Food and Machinery
The protein and amino acid composition of 24 rice samples from 8 late indica varieties in three production bases were determined. With FAO/WHO provisional pattern of amino acids as reference, a comprehensive evaluation model for rice protein was established by combining modified analytic hierarchy process (AHP) with grey correlation analysis, and the feasibility of the evaluation model in evaluating the nutritional value of protein was verified. The results showed that the quality of rice protein was significantly different among different bases and varieties (P<0.05). The correlation coefficient r of the weighted grey correlation method with PER and NPR was 0.959 (P=0.003) and 0.974 (P=0.001) respectively. The results demonstrate that the weighted grey correlation degree is highly correlated with biological indexes of protein quality, which can characterize the nutritional quality of rice protein scientifically and effectively.
