The desire for spicy food has
grown phenomenally over the last 500 years or so. Initially, red chili has been cultivated for its role as a
flavor enhancer. It had been used
to spicing-up maize-based diet. Red chili has been known to contain a rich source of vitamins; vitamin A and C. It also has antimicrobial
properties, which the function of that is for helping the distribution, beside using cold preservation. This is stated by Spence (2018), that the
ability of chili by releasing an endogenous opioid as antimicrobial compound
may have helped the distribution toaround the world.
Capsaicinoid has been known as flavor compound
in red chili. Lu et al. (2016) said
that the research of anticancer and
antitumor on capsaicinoid have killed cancer cells in the
prostate, skin, breast, colon, lung, and human bladder. Besides capsaicinoid, carotenoid in red chili has an important role.
Carotenoid is yellow-orange-red pigment, that can be found in botanical
photosynthetic plant, algae and microorganism. In addition,the functions of carotenoid are as a color pigment and protects plant tissues from the light.
In recent years, this compound has
been able to be used as protecting agent againts degenerative
deseases.

Red chili becomes one kind of food
commodities that has high content of
carotenoid. There are 50
structures of various carotenoids in chili that have been identified. Post-harvest
handling and processing give a good effect in carotenoid bioavailability of food matrix. The food material will be injured by the processing, so that carotenoid can breakdown easily by oxidative
enzyme and other oxidative substances.This will cause discharge and dissolution of carotenoid.
In red chili processing production, storage takes role in
carotenoid reduction process. Compared with bell-pepper, red chili has lower
numbers of reduction. Carotenoid reduction process in bell-pepper can be
identified by colour degradation because of several factors that affect bell-pepper fruit during storage,
i.e. temperature and water activity (Aw). Amethod that is capable to prevent
carotenoid reduction during storage is using vacuum packaging. According to research conducting by Duman (2010), packing
red chili by using flexible vacuum-hermetic (80 – 100 mmHg) gives the advantage compared with traditional
storage, where is
observed from quality parameters such as colour, odor and aflatoxin content.
Commonly, preventing carotenoid
degradation in storage can be achieved by reducing relative humidity(RH) and light
intensity.
Heat treatment of
red chili can help reduce carotenoid degradation before its storage, i.e. blanching method
at 70 to 1050C. It is because
of the enzyme will be inactivated. In red chili
pickle product, pasteurization process with 20% NaCl and 2% acetic acid at 830C for 5,2 minutes is the
optimum condition to reduce carotenoid
degradation. Besides that, heat treatment at
10, 90 and 1000C for 5 to 10 minutes will reduce carotenoid in the amount of 25-34% in red chili and 20-53% in bell-pepper.
