Classification and Processing Optimization of Barley Milk Production Using NIR Spectroscopy, Particle Size, and Total Dissolved Solids Analysis

Table 2

Particle size parameters of spent grain used for barley milk production. Results are expressed as mean of 3 measurements ± SD.

Spent barley grain sample	(0.5)	[3,2]	Specific surface area [m^2 g^−1]
B_15 s	509.28 ± 35.06^a	34.97 ± 1.84^a	0.17 ± 0.01^a
B_30 s	286.76 ± 11.41^b	30.39 ± 0.97^b	0.20 ± 0.01^b
B_45 s	218.40 ± 10.99^c	26.43 ± 1.33^c	0.23 ± 0.01^c
B_60 s	144.55 ± 13.31^d	25.70 ± 0.97^d	0.23 ± 0.01^c

Values in the same column with different letters are significantly different (Duncan, < 0.05).
