2.1. Preparation of batters and shrimp nuggets
Four different shrimp nuggets were prepared and manufactured
according to the formulations shown in Table 1. A reference batter
was prepared by mixing Egg powder (10.4 gr/100gr) and wheat
flour (89.6 gr/100gr). In CMC formula 1 gr/100gr Carboxymethyl
cellulose (Sunrose, Japan)was added, replacing the same amount of
batter wheat flour. The water/dry mix proportion was always kept
at 2:1. The temperature of the water before mixing was 25 C. The
Metapenaeus affinis shrimps used were obtained from a local
producer (Mobarakian, Iran). The shrimps were held under hygienic
condition at 18 C for 2 days before processing. The BG
formula was consisted of 3 gr/100 gr b-glucan in center of nuggets
was used instead of 3 gr/100 gr bread crumb. b-glucan used was of
34 gr/100 gr purity and obtained from promOat (promOat, Swedish).
The cleaned shrimps were ground by grinder and according to
the four formulations shown in Table 1. Additives were added and
mixed to make rawnugget paste. The shrimp formerwas filled with
paste and shaped nuggets. After forming, predusting, battering and
breading was done respectively. Then raw nuggets were steam
cooked for 35 min to achieve an internal temperature of about 85 C
