INTRODUCTION
Surimi waste, such as the heads, bones,
scales and skin of fish from surimi processing
plants can be an alternative source for producing
fish sauce. Most fish used in surimi processing
are Nemipterus sp., Saurida elongata, Johniusspp.
and Priacanthus tayenus. About 40% of the waste
from a surimi processing plant each day is usually
used as animal feed (Pacific Marine Food Products
Co., Ltd).
Proteinase enzyme is necessary for
fermenting fish sauce and other fermented foods.
Bromelain, papain and ficin are proteolytic
enzymes used in several kinds of foods. In this
research, bromelain from pineapple waste was
chosen for the acceleration of the fermentation
phase in the condiment products. Bromelain is an
enzyme found only in pineapple plants (Laura et
al., 2005; Gupta et al., 2007). The largest amount
of this enzyme (36.1%) was found in the stem.
The amount of enzyme is greater in older pineapple
plants, with at least 53% in a five-year-old plant
compared to 11% in a one-year-old plant
(Pukrushphan, 1990).
Bromelain is used in many food
industries. The Japanese have used bromelain to
improve tofu by increasing the taste and flavor
compared with using fungi (Pukrushphan, 1990).
Bromelain has been used in fermented fish
products, such as fish sauce, fish paste and Pla-ra
to accelerate the process by reducing the
fermentation time. There has been some research
on using bromelain from pineapple plants to
accelerate the fermentation process. Chuapoehuk
et al. (1981) reported that bromelain can be used
to produce fish sauce from freshwater fish like
Crossocheilus reticularis Fowler. The activity of
bromelain is related to temperature

INLEIDING
Surimi afval, soos die hoofde, Bones,
Vel en Skale van surimi van Fish Processing
plante kan 'n alternatiewe bron vir die vervaardiging van wees
vissous. Die meeste gebruik word in surimi Fish Processing
is Nemipterus SP., Saurida elongata, Johniusspp.
en Priacanthus tayenus. Sowat 40% van die afval
van 'n surimi Processing Plant elke dag word gewoonlik
gebruik as dierevoer (Pacific Marine Food Products
Co, Ltd).
Proteïnase ensiem is nodig vir
gis vissous en ander kos gegiste.
Bromelain, papaien en Ficin is proteolitiese
ensieme wat in verskillende soorte kos. In hierdie
navorsing,
Pynappel bromelain van afval is gekies vir die versnelling van die fermentasie
fase in die kruiderij Produkte. Bromelain is 'n
ensiem wat net in Pynappel Plante (Laura et
al, Twee duisend vyf;.. Gupta et al, 2007). Die grootste hoeveelheid
van hierdie ensiem (36.1%) is gevind in die stam.
Die bedrag van ensiem is groter by ouer Pynappel
Plante, met ten minste 53% in 'n Vyf-jaar-oue Plant
in vergelyking met 11% in 'n een-jaar-oue Plant
(Pukrushphan, 1990).
Bromelain word in baie Food
Industries. Die Japannese gebruik bromelain te
verbeter deur die verhoging van die Tofu smaak en geur
in vergelyking met die gebruik van swamme (Pukrushphan, 1990).
Bromelain is gebruik in gegiste Fish
Produkte, soos vissous ,.
Vissmeer en Pla-RA om die proses te versnel deur die vermindering van die
fermentasie tyd. Daar het 'n bietjie navorsing het
oor die gebruik van bromelain van Pynappel Plante om
die proses fermentasie te versnel. Chuapoehuk
et al. (1981) berig dat bromelain Kan gebruik word
om vissous van varswatervis soos Produseer
Crossocheilus reticularis Fowler. Aktiwiteit van die
bromelain is verwant aan temperatuur. (1981) berig dat bromelain Kan gebruik word om vissous van varswatervis soos Produseer Crossocheilus reticularis Fowler. Aktiwiteit van die bromelain is verwant aan temperatuur. (1981) berig dat bromelain Kan gebruik word om vissous van varswatervis soos Produseer Crossocheilus reticularis Fowler.
